Bikes are becoming a convenient form of transport with people becoming more environment-friendly. While most designers are focusing on making bikes that fold easily or lock more securely, the MIT Senseable City Lab has come up with the Copenhagen Wheel, a hybrid e-bike which provides feedback on pollution, traffic congestions, and road conditions in real time! Controlled using your smart phone, the Copenhagen Wheel allows you to capture the energy dissipated during cycling and braking and saves it for a boost when needed. Plan your routes and achieve exercise goals efficiently with this creative design concept of a bike.

I watched the video, interesting, it seems very like the Gtech with a single speed, and I have found with the e-bikes I have one tends to only use top gear on flattish roads, the one gain which is lacking with most e-bikes is the regenerative braking, however I have found here in Wales you need an e-bike with mid motor running through the gears, to get the boost needed on steep hills, my folding e-bike has motor in rear wheel, and although it has 21 gears, the assistance drops off once you drop below 6 MPH, but it is a cheap real motor, son has a more expensive one, which comes in faster so easier to hill start, and also seem to give more punch at low speeds, but once the hill is too steep, then you need the walk assist, wife bike has a button for walk assist and it is very hard to use, mine has a throttle type twist grip, much better, but she does not need the walk assist as much.

The gearing means can't really pedal over the 16 MPH assist limit, even down hill, so using the non electric bike with my wife, she would leave me on a rise, but I would catch up down hill, the 16 MPH is too slow on major roads, the weight is also a problem, mine is 24 kg which is OK to lift into car, but try getting it over a stile as I did on the Shropshire route which follows the canal and it is really too heavy.
