Electric Fixie is a concept bike with one gear, electric drive, and no brakes. It’s a personal project that aims to solve problem of cycling with a fixed gear specially in cities with hilly landscapes such as La Paz or San Francisco. A fixie is a bicycle with one gear and no brakes. Fixed gear bicycles have no freewheel, so the cyclist always needs to pedal. Although there are no brakes as a system, you can stop the bike by pushing the pedals backward, blocking the rotation of the rear wheel. Such braking is called “skid”.
Fixie is popular these days because its design is simple and it’s fun to ride. There is a problem of cycling with a fixed gear bike in cities with hilly landscapes such as San Francisco. While the bike has no gears, riders are limited by the landscape and need to avoid a lot of places in the city. Riding a hill is not so easy, and anyway, you are also limited by the number of hills that you can ride. In order to solve this problem, Electric Fixie has been designed to adapt to the environment, it works just like regular fixed gear bike, but it has additional capability, an electric drive.
Designed by Andrey Avgust, Electric Fixie comes with an electric drive where it creates additional traction for your bike to climb the hill. The regenerative braking also provides battery recuperation. Electric Fixie is capable to adapt to hilly roads, it provides power where regular fixie bikes won’t. The battery is located inside the frame triangle, in the aluminum case of the battery there are 16 accumulators 2170 type with a total capacity of the battery is 80,000 mp/h. The battery weight is only 1,8 kg (3,9 lbs). The percentage of acceleration and recuperation can be adjusted through the handlebars.
