Most new electric vehicles you get to hear about these days are cars, whether they are a hybrid or a full electric car four wheels is the norm. We have brought you news about electric bikes before with the range of Brammo motorcycles most recently. But today we have news of the BMW E-Scooter concept, which could be the vehicle to make battery bikes acceptable.
A great way to improve pollution and congestion of our big cities is to get commuters on to two wheels, and the idea of a two wheeled electric solution will interest some people. Electric bikes that have been released so far have only been short range solutions according to an article on ioLmotoring.
BMW have come up with a bike which instead of having a conventional frame, has a casing which houses the battery cell and electronics which forms a monocoque tub. This has the steering head attached at the front, and at the back a single-sided swing arm with a hydraulic damper.
There are no power figures for the electric motor but it is too big for being mounted on the hub and it drives the rear wheel with a toothed belt. One really clever feature of the bike is when it slows down or brakes; kinetic energy is used to increase its range by up to twenty percent.
The bikes electric components are easily accessed, and there is even an independent system that monitors important data such as temperature and voltage from the battery. To charge the vehicle there is a cable to hook it up to the household supply. There is an earth leakage breaker which will trip if there is a fault to protect the user.
When the scooter is being ridden the motor and electronics are liquid cooled, and when it is charging coolant is moved through the radiator by an electric coolant pump. Unlike electric cars that use liquid coolant for the batteries, the BMW saves space and uses air.
At the moment the BMW E-Scooter is only a concept but it looks to be a big step forward with electric bikes. Thing is though will there be a market for it? Many modern scooters even though powered by gasoline, are extremely economical and cheap to run. They offer a good alternative for car owning commuters who want to save time and money with their journey to work.
Do you think there is a market for electric scooters?
