Patent Battle May Loom Over 'Copenhagen Wheel' Electric Bike 152

curtwoodward writes "Nearly four years after the concept was introduced, MIT spinout Superpedestrian has started selling its $700 'Copenhagen wheel' kits that promise to turn any old bike into an electric-powered, smartphone-connected dynamo, simply by swapping out the back wheel. But they're not alone: a competing startup called FlyKly has already raised $700,000 worth of pre-orders for a similar device. Superpedestrian, which holds exclusive license to the MIT patents covering the Copenhagen wheel, clearly thinks there's some foul play going on. 'Their founder actually dropped by our lab at MIT a year and a half ago, saying he wants to collaborate, and spent quite some time with the Copenhagen wheel team. We'll leave it at that,' Superpedestrian founder Assaf Biderman said."

        Your response illuminates one benefit called out in the article. With a wheel like this, instead of violating the law on descents, you can regeneratively brake, and then use that energy to stay close to the speed limit on ascents as well.

        I bike for fitness, and I fully intend to get something like this one day. I may be looking for an all-electronic drive train, where my cadence and effort are coupled to speed and torque only as a long-term average -- I decide how hard I want to work and what pace I want to maintain, and the power system manages everything else, letting me know if my configuration will either draw my battery down too far or exceed its charging capacity. No more finicky derailleurs, no more chain cleaning, no more chewed-up cuffs or shoelaces. And if the regenerative braking is good, it doesn't really matter that the bike is heavier -- you reclaim energy when coming to a stop, and then tap that energy to accelerate back to your pace.

        But who am I kidding? I'm riding a 30-year-old touring bike. I've put 10K miles on it over the last four years, and I'm still on the original chain, never mind groups and such. I'm not going to be pushing the leading edge (except perhaps with obscenely bright headlights).

        • It's not a bad idea. If it were actually safe to bike in my area, or if I didn't have a 25 mile commute, I might consider getting this. But it feels stupid to drive somewhere just to go biking.

      • After a few months of biking regularly without assistance

        And then repeat at least some of those few months every cycling season. I typically start cycling once freezing weather has left for the year, typically in March, but don't feel up to peak form until the end of April.

        On my bike, with walking effort, I can easily maintain 22-25 km/h on the flats.

        Perhaps the real problem is that flats are a luxury. After a long day at work, an uphill ride home isn't very fun.

        • What is wrong with spike tires?

          And for me, personally, an uphill ride home after a long day at work is exactly what I need to finally relax and let it go. It helps that I live at a mountain and work in a valley.

      • I don't see it as a macho endurance event. My bike is cheap and has flat handlebars and 5 gears. I use it to go places. I am far from fit.

        Not getting sweaty is achievable by adding a motor, or pedaling less hard. It seems to me that the latter is cheaper and more convenient.

        • Pedaling less hard comes with the disadvantages of not getting where you were planning on going in the time-frame you may have imagined. It could also come with the disadvantage of slowing to a stop and rolling backwards when you come to a hill. I get that no everyone needs every new gadget that comes out, but why is it such a big deal for people around here to brag about how unnecessary technology is to them.

          • People aren't bragging about how unnecessary technology is, but instead trying to belittle anyone who isn't in as good shape as they are. They're saving the planet and your fat ass is destroying it. Nothing beats a rider's high except for having a rider's high while being smug about it.

        • Some people will sweat even while pedaling less hard. If there's a hill then pedaling less hard means you will not get up the hill. Pedaling less hard may mean you don't get to work on time so that you can't use the bike for commuting and instead have it for the weekend only.

    • So does mine. But I couldn't ride it to work without getting all sweated up. And my wife, with the repaired ankle (kevlar != tendon), can't ride like she used to.

      How is this regenerative?

      If it swaps out with the back wheel on a traditional bike, it looks like it relies on the traditional rim brakes to stop. Unless it relies on triggering a regenerative brake from a smartphone, which sounds utterly impractical.

      You could probably create one of these electric drive wheels that swaps out with a coaster brake wheel (the one where you back-pedal to stop), but that seems like it wouldn't stop the bike as fast as a coaster brake.

      • You could in principle setup the maximum downhill speed with the smartphone - hit 20MPH and it regeneratively brakes you down to that speed.
        Basically stupid though not to have a little wireless thing triggered by a small press on the brakes.

      • Others have described this as suitable for 'fixies' (fixed-gear) only. In that design, the only torque supplied to the wheel comes from the chain, as there are no brakes. Braking action comes from applying pressure to the pedals on the 'other' side of the stroke. Whatever motor is inside this wheel would then become a generator, providing regenerative braking.
