Video: MIT-Backed Copenhagen Wheel On Sale Now – Gives Your Bike 31 Miles Of Range

DEC 6 2013 BY JAY COLE 16

The Copenhagen Wheel project has been a long time coming.  In fact many bike enthusiasts may have even forgotten the concept debuted 4 years ago at the UN Climate Change Conference.

Now engadget reports the project has been completed and you can now turn your bicycle into a extended range/power assisted EV for only $699.

The concept is simple and the tech is designed to “snap onto a standard 26-inch bicycle wheel, converting your ordinary bike into a powerful hybrid electric version that can cruise along at 20 miles per hour.”

The company says that Copenhagen Wheel’s  48-volt battery has a range of up to 31 miles.  As it is self-contained, there is no throttle, but rather you just increased pedal speed (as you would with no battery on board) and the motor will compensate with additional power.

I saw this and am glad InsideEVs chose to report it “despite that is has no plug”. It is very clever.

My understanding was this has a plug, as they give a 4 hour charge time and removable battery as a spec. I desperately searched for an image of what this looked like with the battery removed and or charging, but have turned up nothing.

This is an incredibly clever product. In my couple trips to Copenhagen, I can see how this could be wildly popular. Biking is commuting over there, not for recreation or exersize as more commonly thought of here in the US.

I don’t know how I didn’t hear about the Copenhagen Wheel in the last four years, but holy shit: this is brilliant.

Being able to convert any existing bike so simply is HUGE. There are millions of bikes out there that can become electrified with minimal labor. The low weight minimizes worries about accidents.

When you think about the developing world, this is amazing. Much cheaper to buy and fuel than motorbikes. The reduction in air pollution could be tremendous.

Um, “peddle speed”? — the speed at which things are being sold? I think you meant, “pedal speed”, or more correctly, “pedaling speed”. (Man, with this kind of grammar, you don’t not going to win any metals. 😉

Hey, stop picking on Jay Coal. 😉

I hate you all, (= And I don’t need no stinking “metals”, writing is its own reward, lol.

I’m not sure I love the idea of having to pedal faster to go faster, but maybe in practice it would be ok. I’ve driven a couple electric conversion systems for bikes and it was nice having a real throttle for when I want a REAL break. It was awesome to give it full throttle and fly down the road without pedaling.
That being said, I would peddle this thing day and night, if I think my city would regenerate my level of support and enthusiasm. 🙂

I’m not sure I like the color. Can it have an led light option for night biking?

Does it come with a deck of cards to make the flapping noise?

Except for the months of the year (like December) which have limited daylight, I do some of my commuting by bike. Its about 8 miles one way. There are lots of bike commuters in my ares. I’ve been passed by some electric bikes, and in some cases have been able to keep up and pass them back — It kind of depends on the grade of the road.

I’ve seen some electric bike conversion kits. The disadvantage of this one is the rotational weight. Weight that is rotating makes a bigger difference than weight that is not. Adding 13lbs anywhere to a bicycle is significant, but adding 13lbs to a wheel is huge. Still, I’d love to try this out.

Would these by legal in NYC?

NYC recently banned electric bikes under a new law, even though they were already banned under a previous law. However, according to GreenCarReports: “there remains some confusion over what kinds of e-bikes are targeted. The NYC law covers any electric bicycle that has a throttle, possibly exempting those where the electric motor only assists the pedaling rider.” So the Copenhagen Wheel might be allowed under the law. I see electric bikes everywhere in NYC, though most are restaurant delivery bikes with a throttle. So I don’t think the new law is being enforced.

I was curious about what the fine is for riding an electric bike in New York City. Under this new law the fine was increased from $500 to a whopping $1,000!!! To add insult to injury, the NYC Police department has also been confiscating the electric bikes. According to, “most of the blame on the crackdown is being put on food delivery men who often time ride ebikes at reckless speeds.”

Citizens of NYC should write the Council/Mayor and tell them that instead of the e-bike, they’ll go back to the Humvee.

NYC just began a bike share program, like Boston’s. They closed ours for the winter, and I’m considering the also impressive developments in folding lithium scooters (like a Razor), for that last mile between work, and the EVSE.

There are already several manufacturers of hub-based electric bike wheels.
