German E-Rocket (bicycle/motorbike 50mph)

Electric bikes have a field of application currently in, for instance, a mid-distance commute in a rural area, say 15 miles. Not easily done for many people on a non-electric assist bike, but quite easily done on an electric bike.

The bike in the video is clearly overkill and so advanced that it really blurs boundaries. Without figures on energy consumption, it's not possible to tell how 'green' it is. But who knows? It may plug more of the gap between motorcycles and pedal cycles and may enable more people to discover the pleasure of less motor-dependent transport.

It's still way too fast. The primary objective of any sustainable transport policy is not to cater for the high need to travel, but to reduce it. A bike that seemingly offers such mobility can only be as counterproductive to sustainable land use planning as other motorised vehicles.

What?? Rural area? Overkill?? Too fast!? The reason most people don't ride bicycles is because they're too slow!

Sorry to drag you out of your bubble, my friend, but a lot of people do not care about how 'green' a form of transport is, only the price, speed, and comfort and the trade-off between them. These are faster and more comfortable than a bicycle, only it's price is higher. Once more companies start manufacturing them, the price will come down. I hope they sell hundreds of thousands.
