BMW Motorrad E-Scooter concept gets detailed
11 July 2011
The BMW Motorrad Concept Vehicle BMW E-Scooter is all-electric, but does its best to provide the range of a regular, internal-combustion-engine scooter.
The point of this exercise was to create an electric mount that could take the place of a scooter commuter in terms of range, power and convenience. The E-Scooter has a daily range of 100 kilometers (62 miles), and it's battery can be fully charged in three hours from a household outlet.
Speaking of that battery, instead of a proper frame, the aluminum casing for the battery and liquid-cooled ancillary systems acts as the frame. BMW says the powerplant is strong enough for "safe and reliable overtaking" on highways and for "hill starts on steep slopes" with two on board.
Lacking a hub motor and planetary gearbox, a toothed belt runs from the electric motor to a belt pulley on the swinging fork pivot, where a drive pinion controls power to the rear wheel via a roller chain. Intense, yes, but what else would you expect of BMW?
