The Erokit electric bicycle built by Stefan Gulas was introduced in Germany. The name is pronounced "e rocket". The 220 pound bike reaches a top speed of 50 mph and seems to get there fast watching this video where the rider is set to pass a car moving at a decent clip. It can be yours for 33,000 euro (about $45,000 USD). eROCKIT electronics monitoring the driver's muscular effort and multiplying it by a factor of up to 50.
The electrically driven eROCKIT is best described as the alignment of two extremely different characteristics. Conventional handling that is familiar to everyone, coupled with a highly innovative and revolutionary propulsion system.
Everything about eROCKIT’s general handling comes from the common bicycle. From using the pedals to accelerate and ride the vehicle, to the rear and front wheel brakes, whose handles are positioned in natural locations on the left and right handlebars.
The revolutionary propulsion system is based on muscle force multiplication and delivers comparable power to a regular motorcycle. This is possible due to the proprietary eROCKIT electronics monitoring the driver's muscular effort and multiplying it by a factor of up to 50. The multiplied force is then transmitted to the rear wheel propelling the eROCKIT to a top speed of up to 80 kph (50 mph).
