Copenhagen wheel?
 
Saw this little video. Looks like an interesting take on the electric bike idea.

Every week there is a new thread on this. :cry:

Glad I could help. Any opinions on the wheel?

Seems a good product to me. Will see.:)

I think putting the battery and motor in the wheel is probably a bad idea. Time will tell. If it sells, it's a good design. If not, ...

I've yet to find a situation where I needed a motor in my wheel. I am the motor, and don't take kindly to the notion of being replaced by a machine.

Someday we'll have bicycles that ride themselves with no need for humans. We'll sit home strapped/wired to machines that stimulate our brains directly, electrically exciting the sensations of riding a bike, along with the smell of pumpkin pie. That'll be nice...

Having the motor in the wheel doesn't seem like a problem, but I'd rather have a separate battery. That way you can get the battery capacity needed for your application and range requirements and you'd be able to charge one battery at home or work while using another.

Wasn't there a company that built something like this about ten years ago - the entrepreneur put about $25 million into it, basically because he was pushing a new motor design invented by a Russian scientist and they decided that bikes were the most logical application. I can't recall the name. Anyway, they were hoping for a military contract which fell through because the NiCd batteries in the wheels didn't have the capacity for the necessary range. Inexplicable, since any e-bike enthusiast could have told them ... but trying to pivot to retail e-bike sales the company went under. It really is a niche market, not enough to sustain an operation of that magnitude.

My point is, the big problem they never surmounted was the battery capacity, among other battery issues. That won't be as much an issue with this one, and maybe they've also benefited from hindsight. Even though 250 watts is on the low side for e-bikes I find myself wanting one. There's something to be said for the simplicity and ruggedness of building the power source, controller and motor into one unit in the wheel. Just taking one wheel off and putting this one on, and adding your wireless control panel, that's pretty compelling.

Where do you ride it? You can't take it on the MUP, since it's a powered vehicle, and it lacks the oomph needed to compete with other powered vehicles on most streets. This is the same problem faced by all electric bikes, Segways, etc.

In the US it would most likely fall into the electric assisted bicycle category like e-bikes not moped nor motorcycle nor medium-speed electric vehicle nor motor assisted scooter nor motor vehicle

Exactly. And like an e-bike, there wouldn't be anyplace to ride it.

Ride on the street, like with any bicycle.

I like the idea but the concept of the batteries taking a physical beating each day worries me. I can see this wheel having many problems so the first generation will become the testers! Maybe in three or four years, I'll take another look.
