Fast Electric Bike - Diy 50mph Electric Bike Now this is an interesting offer. It is unique in the fact that it teaches you how to build an electrical bike as opposed to converting a car to electricity or building your own solar plant in your backyard. Before we go any further however, know that we are talking about bicycles here and not motorcycles. http://alternativeenergyidea.com/fast-electric-bike-diy-50mph-electric-bike-z-mpjjint.html
The Swiss Cruiser Happymaker is the only bike on this list (other than expensive optional Clean Mobile drive system on the the Black Block) to not go the easy way out and use a hub motor. It has a mid drive system which uses an over-sized gear on the rear wheel and a small sprocket on the motor to provide the reduction needed to run the electric motor at the necessary high rpm. This is a fast bike which will set you back 3,000 euros. It has a purpose built frame to hold the battery pack.
