That's pretty sweet. But $500 is where it'll catch on, not $3,600.

  Seriously, I can buy 4 motorcycles for that kind of money.
- idheitmann 16y ago
  Anyone who has built their own bikes quickly realizes how easy it is to get to the order of thousands. $3500 for carbon fiber is fairly reasonable.

It'd feel awfully strange riding a bike without my hands out in front of me. Also: * My crappy commuter bike probably costs between 1 and 5% of the price of this thing. * How's it deal with rain/dirt? * Sometimes I do want to just lock it up. Imagine going to the grocery store... at 22 pounds you don't want to haul it around inside. I have a lot more peace of mind locking up my cheap commuter bike outside. Still, it looks like it's beautifully engineered.

  It was either going to be you or I who responded ;) My biggest concern when I saw this originally was the emergency braking scenario. Which basically involves doing a face plant and using your nose and forehead to slow you down by embedding it in the floor. One of the selling points mentioned in the article is, "you can jump forward off the bike in a crisis; there’s no hardware in your way". Which seems strange as every accident I've had or come perilously close to has been hitting something head-on (from the cyclist perspective... such as peds who walk out in front of you, or cars coming out from a side street). The weirdest thing I find though is just the speed. These things tend to be speed limited as this helps classify them separately from the soon to be coming breed of electric scooters and motorcycles. Obv' electric bike manufacturers do not want to be forced in complying with that set of regulations and all that it entails. But the speed limiting is such that even a commuter on a cheap bike is going to be going the same speed, and a fit commuter will achieve a higher average speed than someone on this thing.

    My thoughts exactly. I guess they put the battery in the tail end to keep it from flipping over when breaking. Still, it seems kind of dangerous. As for speed, many cyclists will go considerably faster than any of these things, especially if it goes downhill. It might spoil some of the fun to be regularly overtaken by muscle-powered bikes...
  - delackner 16y ago
    On the "face plant when braking" angle, even a normal bicycle is at risk for this with a lot of handlebar designs, like the simple straight length of tube I have. I slammed my brakes once last year when a car turned in front of me, and the bike stopped. I kept going, yanking the bicycle to then fly over me. * At speed I now always brace my arms behind the handlebar. * Damn I'm glad I was wearing gel padded gloves. * I am very much considering different handlebars.

    A road bike is a piece of athletic equipment. It can be maneouvered in several ways to emergency brake, drastically swerve or accelerate to avoid an accident. This little thing looks more like a tea cart. With you as the bumper. No way am I riding this dangerous little thing.
- sliverstorm 16y ago
  How's it deal with rain/dirt? Forget that, how's it even deal with rough/uneven pavement!?

You can buy regular bicycles with little electric motors on them here in Japan for about $1,000. That seems a lot more reasonable than completely redesigning the bicycle...
- flipbrad 16y ago
  I doubt many japanese take those on the subway though! I don't recall seeing standard bicycles on the tokyo metro at all, in fact. To the person who said you prefer to lock it up outside a grocery store - what exactly stops you from doing that with this device? The cost is a major stumbling block; mind you, I see a lot of heinously expensive road bikes around London, and I suppose their actual utility is lower (harder to take onto buses and rail services; harder to store at home, in the street or at the office; not electric) I'd be interested to see a study done on the device's eco credentials; I've heard persuasive arguments that electric bikes are greener than pedal powered bikes when you consider the petrochemical requirements of a pedal bike's energy source (your food)...
  - atgm 16y ago
    No subway out where I live. Plenty of older people use them because of the hills/mountains out here. You can see them on the buses that take bikes, or the non-JR train lines that let you take bikes.

Seems kind of overdone. You can barely use the sidewalk in Tokyo without getting knocked down by a middle-aged woman with a huge sun-visor, a bag of groceries and two kids strapped to something like this: http://us.sanyo.com/Commercial-eneloop-bike http://us.sanyo.com/Commercial-eneloop-bike They're just like a regular bike but they assist you when you climb up hills or just plain get tired. The battery behind the seat-tube slides out for a recharge. I would say about 20% of the bikes you see parked by a train station are electric hybrids. edit: I will say though, that the foldability part of this is nice, but I prefer the hybrid approach of a standard bike.
- ot 16y ago
  IMHO the foldability part is the main point. The typical usage seems to be home -> bus or tube stop -> public transport -> office. Here in UK you can't take bycicles in buses or tube. There are indeed foldable bikes (http://www.brompton.co.uk/ http://www.brompton.co.uk/) but they are a pain to (un)fold and they are not electric. Still, price and limited autonomy are real issues. At 1K$ and 20 miles of autonomy I would probably buy one.
  - samatman 16y ago
    As a ridiculously happy Brompton owner and fanboy (how's that for a disclaimer!) let me assure you that they are no pain at all to fold or unfold. I have challenged a dozen people to get their bikes locked to a post in the time it takes me to fold the Brommy. No one has succeeded to date.
    - ot 16y ago
      Good to know, I withdraw my objection about folding :) Still, they are not electric and cost around 1400$ EDIT: This video shows how to fold/unfold one http://www.youtube.com/watch?v=pNnOdoUn3kg http://www.youtube.com/watch?v=pNnOdoUn3kg . I'm sold!
    - delackner 16y ago
      You must be leaving out some salient details on why it takes your friends such a long time to lock up their bikes. You live in a city with a high bicycle theft crime rate perhaps? So how long are we talking about? The video links by the next commenter shows it taking about 20-30 seconds. I manage to lock up my bike with a simple 4 digit combo chain in less than 10 seconds, but I can get away with locking it to itself in Tokyo :)
noonespecial 16y ago
Bicycles enjoy a kind of special status in the US when it comes to tort law and manufacturer liability that is shared with many other older designs. People know they are dangerous and automatically accept this. Things like table saws, ladders, kitchen knives, and roller skates are other examples of things that fit this category. Inventors of this type of device face a steep uphill climb in the litigious climate of today's United States because its so completely different than traditional bikes. I'm not saying its impossible, I'm just saying that things like this will be magnets for the lawsuit-lottery. I wonder what the ratio of lawsuits/Segway vs. lawsuits/Schwinn happens to be...

Clearly someone hasn't read PG's The Trouble With The Segway: http://paulgraham.com/segway.html http://paulgraham.com/segway.html
- gjm11 16y ago
  PG says: "Someone riding a motorcycle isn't working any harder. But because he's sitting astride it, he seems to be making an effort. When you're riding a Segway you're just standing there." and: "So there may be a way to capture more of the market Segway hoped to reach: make a version that doesn't look so easy for the rider. It would also be helpful if the styling was in the tradition of skateboards or bicycles rather than medical devices." This thing does in fact look rather like a bicycle, and the rider does sit astride it. Perhaps the YikeBike people have read PG's note about the Segway. On the other hand, I think it still makes it look as if the rider is "too lazy to walk". If that (rather than, say, the $3600 price tag) makes the YikeBike fail, then it'll indicate that PG's basic analysis was right even though his proposed ways of solving the problem were wrong.

  "When he rides the Eunicycle, people smile at him" There is a chap who commutes through central Edinburgh on a unicycle and it does indeed cheer me up every time I see him.

Frankly, I don't see the point of electric bicycles. I have not seen any electric bicycle that offered any real advantage to a normal muscle-operated one. As a matter of fact, bicycles are one of the oldest and most refined technologies available to us. They are marvelously efficient, they are light and versatile. Adding an electric motor and battery makes them heavy, limits your range and decreases the amount of control you have over the bike. Which is nice for, say, elderly people. And maybe you are American and you don't know this, but many European countries have excellent biking routes everywhere and cars actually brake for cyclists. All that talk about cycling being dangerous is mainly an American problem. In most other countries, bikes are actually a lot safer than cars for the simple reason that they don't go as fast. I think bicycles are plain fun. I ride my bicycle to work whenever I can. I love my bicycles. All three of them!

  > I think bicycles are plain fun. I ride my bicycle to work whenever I can. I would do the same, if only we'd have a decent shower at our workplace, so that I won't smell all day after a bike-ride from home. Nevertheless, I can't wait for this winter to be finally over so that I can take my bike for photo-taking rides outside the city I live in. (if it matters, I'm a fellow (East-)European whose city doesn't have that many bike-lines, but it doesn't matter anyway, cause I've first ridden a bike on a national road at age 12, so nothing scares me :) ).

  > I have not seen any electric bicycle that offered any real advantage to a normal muscle-operated one. Some people don't have showering facilities at work, or do not want to carry a change of clothes with them. An electric bike is less likely to produce a stinky cyclist.
  - Derbasti 16y ago
    Most electric bicycles only enhance your own pedaling. This makes you faster, but it won't make you sweat less as you can still exert the same force (only to greater effect). In other words, if sweating is the problem, ride slower. Personally, I ride slowly to work, and fast back.

It seems horribly unsafe in case of an accident. Sure, 15mph is turtle speed when it comes to bicycles (disclosure: I've been racing road bicycles for five years) but you can still get hurt pretty horribly if you fly out of that thing. There's no frame/hand compression to stop you. Also, it doesn't look like a bicycle, at least compared to something in the similar price range: http://www.londoncyclesport.com/Assets/LondonCycleSport+Digital+Assets/bike+bmc/bmc091.jpg http://www.londoncyclesport.com/Assets/LondonCycleSport+Digi...

  Not to mention he isn't wearing a helmet! [NB I've had one accident where a helmet definitely saved my life and a couple of close calls - two my own fault cycling off road and another where kids threw a brick at me].
pmccool 16y ago
The more I think about it, the more the 6-mile range sounds like a crippling flaw. Hills and headwinds will presumably knock this around, but that aside, there's just so little room for error. Forget to charge, make a short detour to buy groceries and there you are walking home with a bag full of perishables and an immobile chunk of carbon fibre. Nice to see some attention paid to lighting though. It's an important issue for commuter bikes, and one that doesn't seem to get as much attention as it should.
lacerus 16y ago
I tried an electric GoCycle the other day. It is the best looking folding bike I've ever seen, reaches 30 km/h (faster than all other cyclists around you) and you don't smell when you arrive at work. http://store.gocycle.com/ http://store.gocycle.com/ Also you can fold it up and take the subway if it starts to rain unexpectedly.
ntoshev 16y ago
That's too far from the bike concept and way too expensive. I may try electrifying my bike, a local guy does this and it looks reasonable. You can see the pictures here: http://prodavalnik.com/sglobyavam-elektricheski-velosipedi-po-porachka-pr-i1260639 http://prodavalnik.com/sglobyavam-elektricheski-velosipedi-p...

I think this product could be a hit, with a bit better design and manufactured at scale.
mechanical_fish 16y ago
I don't know about the bike itself, but the pricing is an excellent innovation. Now I can buy the Brompton of my dreams, secure in the knowledge that I'm getting an amazing bargain. In other news, it might be time to reread Cialdini. ;)
marknutter 16y ago
Too bad you look like an idiot riding one of these things. There's a huge barrier of entry for strange and unique transportation devices, and that's the strong aversion most people have to sticking out like a sore thumb.
