Look at a lot of new energy vehicles, today we look at pure electric motorcycle. BMW, one of the first to be involved in the development of electric motorcycles, launched an electric concept motorcycle called vision DC Roadster in June. Today, BMW unveiled a test car called the E-Power Roadster. From themedia exposure of the test car, due to the presence of batteries and motors, the new car’s frame looks unusually bloated under the car frame, the weight of the vehicle also reached 289kg.
But the parts were also borrowed from their own existing models. The battery pack comes from the 2-series PHEV, and the electric motor is taken from the long wheelbase 7 series new energy models sold in the Chinese market.
The grafted powertrain gives the BMW electric motorcycle, which is still in the development stage, a maximum power of 136 horsepower and a maximum torque of nearly 200 Nm. According tomedia reports, the electric motorcycle 0-100km/h acceleration time of 2.9 seconds, only 0.2 seconds slower than the sports car S 1000RR.
More importantly, this BMW electric motorcycle eliminates the chain-drive of conventional motorcycles, powered by a drive shaft to the rear wheels. Imagine the horror of the seamless connection of the electric motor with the drive shaft… This test car is not very clear, then bmw announced the concept car, may help people to better understand the car look.
It is reported that the electric motorcycle can be fast charging, one minute can increase 4.8 kilometers of battery life, in 30 minutes can increase the power of 90%. When the battery temperature rises above 40 degrees C, the speed of charging decreases rapidly, and BMW is currently developing a charging cooling system to solve this technical problem.
In addition, according to BMW officials, the future of new car life is expected to be further increased to 201km-297km.
