46 Analysis : "This Way" Commuter Bicycle Concept

'This Way' Commuter Bike : Pictures Courtesy of Bicycle Design & T.Dohmers


In October last year, the Bicycle Design blog hosted a competition called "Commuter Bike For The Masses". The theme of the competition was centered around designing a 'transportation-oriented' bicycle to try and reel in (or attract) the vast "blue ocean" of people out there who don't ride at all, and have zero prior interest in cycling. Design and form factors were entirely up to the designers. The idea sounded fun, and Cannondale sponsored the competition. Winners would get a grand prize equaling a free Cannondale Bad Boy Bike, valued at 1000 US dollars.

The 7 jurors were :

Out of 65 total entries, it was announced that 6 made it as finalists. They had some interesting, and creative concepts from a bike that would become a lock when folded, to bikes that had a car like feel to them, both from a design standpoint and other specific elements such as the idea of using 'keys' to get something unlocked.


Yesterday, the winner was announced and it was the "This Way" commuter bike concept from designer Torkel Dohmer. Congratulations!! Man, I fail to see how you can't enjoy that grand prize!


Here are my thoughts on the design, and you can think about them too :


1. ALL CAR DRIVERS? : It appears it was taken for granted in the competition that all non-cyclists drive cars. How about those who take the public transport system in cities (many are happy with public transport) ? What about the many others who're much satisfied with walking? How about those who don't want anything to do with cars at all? Will a design that looks and feels like a car answer all the questions?

2. JURY : Close to 60% of the jury I mentioned before consisted of people who ride bikes or are in the bicycle business. How can you avoid a selection bias or be able to get information from people who don't ride, like through a survey?

3. SOLAR PANELS? : In the design rendering, there are no solar panels depicted at all on the roof. Just a mere glass like structure. That doesn't say much, does it? Moreover, while solar power isn't necessarily bad, it could be expensive. In 2005, the price of solar panels averaged about $3-$4 USD per watt of installed power. The designer of the bike has to calculate how much power all his electrical equipment in the bike would need and justify the costs of buying, and installing solar panels to run the calculated watts and amperage. Then compare those costs with batteries. Whats a better option?

4. WEATHER PROTECTION : By weather, I take it that this bike can be ridden in the rain. The bike has a roof, so it is supposed to have that weather protection. But does rain only fall directly vertical?

The bike also has solar cells on the roof, which, according to the designer must power the bike's built in LED lights. How do you protect all that equipment when it rains? Attention must be also put on the fact that the sun isn't directly overhead all the time. Solar panels in the real world are able to tilt and position themselves correctly relative to the sun.

5. SNOW : Conventional bikes can be ridden on the snow using different tires and many commuters ride to work in the cold. Due to This Way's low rider position and small wheels, I highly doubt whether it'll be possible to achieve this.

6. DRIVE TRAIN : The bike has a "belt drive". Belt drives don't work with multiple gear sprockets. You could, however, pair them with an internal geared rear hub but you probably won't be able to enjoy some things. That may also cost more than simple sprockets.

7. SAFETY : Will a rider be really safe with a low center of gravity? What if consumers think aerodynamics is not as important as safely getting somewhere. Will he or she be visible to the traffic? When its time to brake and stop, how do you get out without tumbing either way due to a loss of balance? And finally, a few things about the windshield :

1) I'm not sure how the designer aims to make the windshield. If it is some plastic or polymer, then the issue of scratches on it comes up.

2) If its going to be made of glass, there's no telling when the rider can impact his head on it in case of an impact or accident. My next question would be : Should a seat belt be provided to the rider? What would be the industry standards that have to be followed for vehicles with windshields?


3) The viewing range of the windshield can be restrictive to observation. Notice how its not only narrow, but the windshield frame itself can block the rider's view ahead. This may or may not be an issue, but still something to consider.

8. RIDING POSITION & COMFORT : I like the concept of a recumbent riding position for a commuter's bike for the masses, but it seems to me as if in this winner's concept, the rider's arms will be outstretched at the handlebars. How comfortable will turning and maneuvering the bike be in corners and in climbing on hills? In conventional bicycles, a rider can stand and pedal to generate more power on hills. However, no such provisions are on the This Way bike.



Also note that from the rendering, the design of the handlebars makes it possible for them to strike the windshield frame on turning.




9. PARKING : Without a stand or a stable support point, how do you park a two wheeler such as this? And what facilities are there on the bike itself to use with existing public bike racks?

10. BIKE TRANSPORTATION : Will this bike fit into a bike bag or an aftermarket vehicle rack for transportation? I don't see that happening knowing what exists in the market today. in high density urban areas, cyclists are seen placing their bikes onto trains or buses. Given the big dimensions of the This Way bike, I hardly think that's possible.

11. MATERIALS OF CONSTRUCTION : The concept is to be made out of carbon fiber or flax fiber, and hydroformed aluminum. We all know that bicycles and velomobiles made out of carbon fiber are not cheap.

12. PRICE POINT AND LIFECYCLE COST : The judges think that to keep costs down, this concept could borrow ideas from toy and boat manufacturers and be made to sell under 500 dollars if volume took off. Pay attention. "IF VOLUME took off". Otherwise, they think selling point will be around a 1000 dollars. Now, none of the judges have talked about a certain element called 'Risk Assessment'. By using composite materials and having solar panels on your roof, is it guaranteed to attract consumers? This isn't simple to answer in a day or two. Its all too simple to sit somewhere and say, 'My idea is going to be great. Lots of people are going to buy it. My competitors will be dum as well. They won't figure out a cheaper, easier or more innovative way to do things.'

Keep in mind that the materials of construction, solar panel and electrical transducer equipment, wiring and the extra cargo attachement that goes with the bike can all bump up costs. To rely on manufacturing methods for toys and boats can also have its own set of agendas to follow, such as having to follow different sets of standards or testing. Considering all this, if it can still be sold for 1000 dollars, great. But is 1000 dollars what everyone wants to pay for a commuter bike? And over a period of its life, how costly will it get for the average Joe to maintain, replace and buy new parts due to damage, wear and tear?

13. COPY, NO COPY OR JUST DESIGN IMPROVEMENT? :
In the summer of last year, I saw a concept very similar to This Way. It was a solar powered bicycle designed by Miroslav Milijevic based at Z & Co. Design in London. It was called Cycle Sol (Sol may be short for Solar). The only differences I see are that Cyclesol has an electric assist motor, the handlebars are positioned at the sides, the seats look a little less comfortable and wheels look more solid. Even though such a design was shown months earlier, even it seems like it didn't transform into reality till now. Yet, the design renderings have substantial detail in them, which is how I think a proposal should be submitted.






14. WILL IT TAKE OFF? : For all the publicity that surrounded this competition, what I'm really interested in is will the concept see the light of day? Congratulations to the winner, but there appears to be a need to have a reality check put on the design. I hope you can work and build upon the apparent practical disadvantages I and many others see in this concept.

At the end of the day, ask yourself the question :
Is poor bicycle design really the culprit in keeping people away from cycling, as opposed to safety problems, poor infrastructure, poor riding facilities and poor advocacy programs by governments and other authorities? If it indeed is, by how much (like a %) ? What amount of role does it play in discouraging cycling? Because if it is indeed a tiny % compared to other factors, then maybe the best efforts to get people on bikes can be achieved through strategies trying to improve those other factors.

    Excellent analysis.

    One reason most bicycle companies don't pursue projects such as this is thats its too risky. The price is high, the bikes are heavy or clunky, and for the most part they don't end up attracting a lot of people into riding.

  4. there are different cars and trucks for different uses. the same thing happens with bikes. you cannot have the perfect bike for all seasons and terrains. i understand this design tries to address the issues of alternative transportation in the city and its suburbs. for touring and hill climbing look elsewhere.

  6. Thanks for the comments.

    I was thinking of something : Given that this concept has won, why don't someone try and make it a reality? I think Cannondale should take this designer's idea abroad and work with him to make something practical in the next few months/years. I really don't wish to see this design withering away on paper, just like the rest of them.

    Ron : Someone above talked about your negativity. Such negativity is hardly anything new. The conflict at work between conceptual designers and engineers are seen even in the car industry. The designers will freely play around with form and create clay models, but whatever they come up with irks the engineers who're really the ones who build this thing up, and put life into it. I think what would be needed in good bicycle design is a team of people, not just one. Communication is very important.

    The design is not viable.
    A similar incarnation was attempted in the 70's and failed miserably.

    Does any designer actually do any research before they start on stuff like this?

    To all who commented here and the author : This is a first step concept. It will take lots of work to make it practical. There's no point in arguing that its a horrible design. The designer most likely knew that this is just a rendering of his idea, not something that he should provide someone with to ride immediately.

    Carrying on from annon 11:16

    Jonathan Ives (Apple designer) said recently [paraphrased] that new concepts at apple are like precious new green shoots, and need to be protected or they are easily trampled on by the mass of opinion with no vision. I think this applies to any new concept - it is so easy to trample on. But by understanding it is still very young and at a very early, even embryonic stage of development, he with the help of Steve Jobs feeds and grows it in sealed incobaters - to emerge later as the sorts of products that apple is renowned for.

    Apple design is staffed by creative people both creative engineers and creative designers.
    They recognise that engineering can also be a creative activity, even though not all modern engineers are creative ... by understanding the need for new ideas they make a positive contribution.

    ReplyDelete
  12. Ron, Torkel plans to explore the concept a bit further and possibly build a prototype. As others have pointed out, his concept is just that at this point- a concept rendering. I will certainly pass along any further development work that he does if that is what he wishes.

    Anon 9:20, great comment about design and engineering at Apple. In my career as an industrial designer, I have worked with some really great creative engineers who get pretty excited about working though problems together. I have also worked with a few who want to kill every new concept by pointing out past failures of something they consider similar. The key is to understand that a product has less constraints at the beginning of the conceptualization phase. As the designer and engineer move through the development process, those constraints become tighter and the issues get solved one by one. It is definitely a collaborative process.

    ReplyDelete
  13. James : Thats good to hear. If Torkel has the resources to get something underway, great. Hopefully he won't fail to take into account the majority of practical disadvantages we all see from his initial renderings.

    Speaking of Apple, I'm reading a book called Apple Confidential 2.0, a history of the Apple company. So far its been very good.

  14. This design looks kind of fun but I think your final paragraph sums up the problem, Ron. For example, Shimano`s whole Coasting technology is based on the idea that fear of shifting is keeping people off of bicycles. I do not think this is the case but rather the lack of roads that can be cycled safely in North America. From an engineering standpoint (rather than a marketing one) can it be said that this design is truly an advance over what we are already riding to work? My NYCBikes crossframe probably cost around $700 to build, and is festooned with lots of blinky lights. It has a solid rack and I carry panniers on it for my gear. It is easy to fix, carries lots and actually fun to ride. It is no big deal to store it or chain it to a bikerack. It does not have a roof but in the proposed design you are still going to get wet in the rain (and where do you put your shopping?). I have been struck by the fact that bike design has advanced very little since the early 20th century but it might be that the current design--strong, simple, pretty cheap--just works so well. The competition was pretty entertaining, though.

    ReplyDelete
  15. Sprocket : Excellent point you make. I have no arguments against human factors design in bicycles. In fact, you cannot take for granted that what you design is intuitive for everyone to use, with both comfort and ease.

    If Shimano's idea was to get more people on bikes by introducing better shifting, so be it. But for every explanation, there's an alternative one. I would have been glad to see some research data from Shimano saying that yes, in the global scene, x amount or x percentage of people don't ride or are fearful to ride because they DON'T know how to shift! However, Shimano hasn't produced anything like this for us. I can't blame them. Shimano, like other bike manufacturers, have to come up with SOMETHING every year to make money.

    I like your point about Life cycle cost. Thats something consumers hardly think about. It would be great to have a "Cradle To Grave" cost assessment of this bike and compare that with alternatives. Thats the way I would do it.

    Its interesting how design concepts can be so out of touch with reality. For example, how is the proposed belt drive transmission going to fit in this bike? I suppose the frictional drag caused by a curved and twisted transmission line will far outweigh any benefits I see in the design.

  19. Anonymous12:21 AM

    I think the concept is great. Sure you can pick a million and one reasons it might not work, but it sure throws some possibilities into the ring. Why should it need to be a practical idea that could be manufactured tomorrow? It's a concept...

    So many of the points you raise are possible problems, but could so easily be engineered out of it or may not even be a problem.

    Disappointingly negative post, what ever happened to creative criticism.

    ReplyDelete
  20. Anon : No where have I said Torkel should drop his idea and just walk away. But even you won't deny it - the questions I have posed is something every rider will ask.

    It also depends how you define "creative criticism". I'm a pretty straight forward guy. So if you mean I should sugar coat criticism, sorry I can't do that well enough. Maybe I should try harder.

    Read the design brief from the original competition announcement. It says: "do make sure that your concepts are based in reality (don’t break the laws of physics, etc) and that they are manufacturable using existing technology"

    In my opinion that requires practicality.

    The purpose of competitions like this is maximizing media coverage. Cannondale got quite a few blog mentions in ultra positive context with the price (not retail) of one bicycle.



    This is not my bike, but I think it is a very sensible and useful commuter bike. It could use a chain guard and front basket or rack to make laptop loading easier, but panniers work well too. Smart, sensible, useful, cheap, manufacturable and absolutely not sexy or interesting at all.

  22. But let's face it... no amount of cool bicycles are going to lure drivers to become riders. Key issue is laziness and most people are not willing to give it up without a good reason.

    Good reasons include:

    1) Degrading personal health (doctor orders)
    2) Environmental concerns (requires capability to altruism)
    3) Law (requires major change in government)
    4) ?

  23. Asb :

    Lets try and put a number 4) to that.

    Most non-cyclists I talk around here have such a degrading notion of riding a bicycle. They think its slower, you get sweaty, dirty and that your status is somehow lowered by actually riding.

    The way I respond to them is simple. I show them the high efficiency of a human powered bike for energy consumed/km and I also tell them about the tonnage of CO2 a bicycle releases in a year - which is nil (if you neglect the manufacturing of bikes, clothing and the food we consume)

    So :

    4) Absolute ignorance

    ReplyDelete
  24. I just want to add, regarding your last paragraph, that it was acknowledged from the start of the competition that infrastructure improvement would likely make a much larger difference in bicycle commuting popularity. The blog isn't about infrastructure, though.

    Shimano did some homework before introducing coasting, I'd love for them to share it, but they paid for it and I doubt they'll give it away for free. Sadly, they neglected to do a better job education the LBS employee on how to introduce it to potential customers.

    My responses to your initial questions:
    1. A design that looks and feels like a car will not answer all the questions, but a design that looks and feels like a bike has been tried for quite a while now.
    2. Good question, maybe just not in the scope of time/effort for this competition.
    3. This is a design competition that was supposed to be reasonably feasible, it didn't need to be production-ready with all costs and engineering completed.
    4. I actually quite like the roof/windscreen. It may not protect completely, but it will keep the majority of the rain off, which can make quite a difference.
    5. Talk to some recumbent riders from the midwest. I see no reason why the tires on this bike can't be changed for studded ones.
    6. Yes, the cost might be more for an internal hub, but shifting while sitting still at a stop sign would seem an advantage for this bike. What do you mean by "probably won't be able to enjoy some things".
    7. I'm unclear on how center of gravity makes a huge difference in safety? At any rate, this thing will look like a UFO going down the road/path so visibility won't be a problem. I agree that an upright bike allows the rider a better view over car roofs, etc, but none of us can see around an H2 with tinted windows. When you stop you put a foot down, simple. Yes, a kickstand will need to be standard equipment.
    Windshield: There are quite a few plastic helmet visors, motorcycle windscreens, etc. The issue of scratching needs to be looked at, but is not a fundamental design flaw, just a technical challenge. Good call on view restriction by the A pillars needing to be worked out before production.

    8. Yeah, looks like the bars/pedals /seat position may need more adjustment. Again, this is a minor issue, easily addressed before production -right now it looks like it's maxed out for a 6'3" rider. On a conventional bicycle if you want more pressure on the pedals than your body weight, you must pull down on the bars(or be clipped in). On this bike you have a seatback to push into, like the leg press at the gym. I know some recumbent riders who destroy me on hills. Yeah, the turning circle will be huge for this thing.
    9. Yep, needs a kickstand. The frame needs some "handles" or ears at belt-height that one could use to U-lock to a bike rack.
    10. Huge demerit for not fitting on a bus bike-rack. Roof rack on a car would work, or a Draftmaster-style hitch rack. A minivan or long wagon would also work. The solutions already exist for tandems and LWB recumbents.
    11. True.
    12. This will be the biggest obstacle, just ahead of getting LBS employees to sell it. I can't see how this could be made cheaply, but there are plenty of $3k bikes out there that never see a race course, too. People like nice things, and some can even afford them. Long term, I see this being about the same upkeep as a standard bike, maybe less because the drivetrain is protected from the elements. The electronics/solar cells could get expensive, though.
    13. I'd say no copy. Recumbents have been a round a long time, and designing one with a monocoque construction isn't really novel. Same goes for the idea of a fairing or roof, especially when you start looking at motorcycles/scooters with roofs.
    14. I kinda doubt it, mostly for the reasons of your last paragraph. Namely, that there are other larger obstacles to overcome, and a company risking much on a design that may only win a small percentage of consumers might not be an attractive business decision. But I'm no businessman, so who knows?

    Thanks for the blog and the analysis, it's good food for my brain!

  25. The most obvious fantasy in the spec of this thing is the claimed 12-13 kg weight, including roof. That suggests something like an all-cf frame (and a fastidiously light one, at that), which seems unlikely for $500, $1000, or even $2000.

    At the risk of being blunt, most people who don't ride bikes don't want to pedal. Pedaling (and concommitant sweating) messes up your look far more than any rain storm could hope to, and 120 years of commuting have caused some very effective rainwear to appear on the market, and it works better worn by the rider than the bicycle.

    Half the finalists appear to have compromised their bicycles by making them, fundamentally, really heavy. There's hasn't been a lot of call for bicycles to get heavier, at least not from people who actually pedal them.

    Bikes (mostly trikes like the velomobile, really) like these do exist, and do work, but you often hear that the first thing the owner added was an electric-assist. A "hybrid" faired electric/pedaled trike goes some considerable way to being a sensible vehicle, and its weight is mitigated by its electric assist.

    Thanks for stating that jimmythefly. I have seen comments to that effect all over the place today, and yeah, I have acknowledged many times that infrastructure is a much bigger issue. I just think it is funny that so many people keep bringing that up like it somehow invalidates the very idea behind the competition.

    I can say that I have done a LOT of advocacy work in my local community because I do want to make conditions better for all cyclists. I hope that all the other people bringing that issue up in the various comments are doing the same.

  27. Jimmythefly : Here's an invisible trophy for completing the biggest comment on my blog yet. Did the coffee cup on the header motivate you that much?

    I like your discussion with me, as opposed to others who have attacked me from left and right without adding anything valuable to this topic.

    For point # 3 on solar cells, what irked me is that it was almost as if Torkel gave an afterthought to his solar panel idea, even though its one of the central themes. Yet, no evidence of any solar cell in the rendering.

    For a professional presentation, that hardly cuts it. This was somewhat more informal and a fun competition, yet for the prize of a 1000 dollar Bad Boy bike, Torkel could have done more, if not give us pin point accurate engineering calculations.

    Also, reasonably feasible is not feasible.

    Torkel himself declares his design as "feasible" on his website.

    Ryan : Good call. 12-13kg total vehicle for 1000 dollars seems almost utopian to me. Just as an example, the Go-One HPV is around 15-20 kgs total, but costs close to 10,000 dollars. Go-One's cost is not only prohibitive to 90% of the people, but I cannot see how a closed design like that is comfortable for long distance travel, especially if it becomes a greenhouse in the sun. Moreover, with carbon fiber not as durable as traditional materials, covering your entire bike and roof with that stuff is just inviting trouble for your wallet over the long run.

    Check out this upright bike with a roof. Simple add-on for weather protection!

    It would be nice if this was done as a tadpole trike, with 2 front wheels, giving it much better stability to counteract the wind torque the wind/rainshield could add. also make it much easier to maneuver in the city.

    I agree that the handlebars need to be more convenient/lower to the normal position of arms. USS is the way to go.

    Original design and these improvements are all very good and insightful. Well done.

  34. Thanks Anon @ 3:11

    I was thinking a little more about the handlebars. Since this bike was designed to sort of look like a car, why go for a straight handlebar design? Why not do a round shape, steering wheel? You could then maybe have buttons on it to activate the lights. Just a thought. A round shape makes it obvious that the rider can change his hand position better for comfort, as opposed to the limitations of a handlebar. A handlebar isn't even much of a concern here since the rider is most in a recumbent position and he won't be standing on the pedals to climb hills.

  35. Anonymous6:17 PM

    Your comment on a steering wheel is hilarious. After the next few ideas remaining for this design like a bumper, a trunk, and a sunroof for the roof, I think it'd just be better off buying a car instead of riding a toy for adult daycare.

  38. Anon @ 6:17pm : I welcome all kinds of sarcasm but I was only trying to offer ideas for improvement in this design. If you want to downgrade every single suggestion put forth go ahead. Whatever floats your boat.


    Anon @ 7:27pm : Yes, I agree that perception to a degree is responsible for safety concerns. These may be right or wrong perceptions. However, they are present and real and in most cases, there is solid reason for it. Can you argue that the NEED to dissolve wrong perceptions are insignificant and unimportant compared to the VITAL need to keep producing more varieties of bikes? What good is that going to do?

    Root cause prevention is better than cure my friend.

    I have problems with your website for a few reasons. Remember, statistics can play with your mind if you don't do some critical thinking :

    1) No links to actual citations.

    2) Outdated data for our times. Think : the number people may have doubled, the number of vehicles on the roads may have quadrupled from 1990 to 2008! That could increase the odds of drunk driving and crime. New technology, bad companies, bad manufacturing methods can all cause failures in bikes. The injuries, or fatalities from these events aren't explored either. So whether you're skilled or not doesn't mean cycling is necessarily safer. There are lots of variables to consider.

    3) Where's the data for the rest of the world? Do people only bike or have perceptions about it in USA?

    4) What is the cutoff for these rates between urban and rural cycling, road and off road cycling, and just different types of cycling? These are not evident in your data. It may very well be that these numbers pertain to a safer form of cycling while discounting others.

    4) People not only bike for utility purposes, they also compete on it. Competition is an extreme case scenario you can't under rule, where ever it may be.

    5) Other subtle things like increase in popularity of cycling may also increase the rates of injury. These aspects aren't explored by your site.

    4) While your website puts actual numbers to injuries and fatalities, its sort of downplaying it by comparing it with other more dangerous activities. So isn't there a value to these numbers??? Keep in mind that a leg bruised, an arm lost, or a shoulder broken can put you off work, lower the quality of your life and may decrease your privileges in society. Whether a cyclist injures himself lesser than a motorist is not the question. The question is 'HAS THE CYCLIST INJURED HIMSELF?' If yes, its bad and somewhere, something is wrong.

    Cycling is a great and healthy activity but the society at large and the environment within which we bike is the problem. Perceptions are a product of this environment. They don't just come out of no where.

    Interesting link. I think roof is IMPOSSIBLE without going into
    tricycle - and crosswind would make that bike to crash. But trike
    with solar panels and A LOT of cargo space - that sound like a
    possibility. Weight is a bit of a limiting factor as far as
    transporting but perhaps there is a way to tow a big trike behind
    the car?

    Solar as a whole is still more complicated and expensive than it needs to be. I'm currently looking into a solar charge system for a sailboat I'm restoring. My options seem to be spend way more than I consider reasonable (and even then options are quite limited), or patch together an equally efficient and far more cost effective but more bulky and cumbersome system on my own. One would think complete, reasonably priced solar systems would be more common than they are.

    Lighting a bike with it? No thanks, Ive got my hands full trying to light my boat where weight is no concern.

    Until there's a prototype that's actually practical to build, buy and use, it's vaporware. Today's commuters need something that they can buy and use *now*, and this isn't it. Whether it ever will reach the point of being a real product is somewhat worse than just debatable; too many of the "apparent practical disadvantages" are in areas which are well-known to be nontrivial.

    My prediction: This concept will not prove as horribly profitless to
    investors as Moller's flying car, but it will ultimately be nearly as
    unsuccessful, for some of the same reasons. In the case of this
    project, the prototype may well be fully functional, but will prove
    both impractical to build and less useful in real-world environments
    than expected; given that similar attempts have been made many times,
    there is no reason to expect that the results will be different in
    this instance. If it reaches production, there will be a small
    specialty market for it, but the overall response from the marketplace is unlikely to be enthusiastic.

    The windshield is a BIG issue. Polycarbonate is hard to mold in way that does not have severe optical distortions, and is easily scratched.Sailplane canopies overcome this by being hideously expensive and handled with extreme care on the ground. A glass windshield can overcome these problems, but at a significant cost on weight. Defogging the windshield in poor weather is also a major problem.

    I suspect this is why a lot of velomobile designer have gone to the "exposed rider's head" design.

  43. Anon @ 2:15 : How about acrylic/plexiglass? Windshields in motorcycles are made out of them. However, its only about 3% as impact resistant as polycarbonate, according to this website. Same website has some interesting things to say about Von Karman vortice generation on windshields. Bad for aerodynamics I guess?


    DankMTB : Solar energy is perhaps the most available and all forms of life use it in some way or fashion (except some in the deep ocean). However, cost effectively applying this to modern houses and vehicles is an entirely different thing. While it all sounds nice and 'green', the cost is still prohibitive as of today.

    Here's a CNN tech article writing that solar cells in automobiles are still a long way off from today. Its a far reaching goal. According to the article, Toyota has huge plans to incorporate solar panels into their cars but the project will take years to bring the costs down. This is why I'm suspicious that "This Way" from Torkel can be cost effectively produced at 1000 dollars as one of the judges said in this competition.

  45. to your last point/question - I don't think it's design, or safety or infrastructure that limits people's participation in cycling as an alternative means of transportation. I think the majority of people are just lazy.

    I think its also an image thing - some folk just have a negative view of cycling . period . such as .. 'for folk who cannot afford a car', 'for athletes', 'for enthusiasts', or for nerds ? .... I am non of the others so I guess I am a nerd :-)
