When you read that the maximum speed achieved by these electrics at the Isle of Man was just 140 mph, you must understand that the present state of battery technology requires that the limited battery energy be used where it has best effect on lap-time, while also preventing harmful effects such as motor, power supply, or battery overheating. In this sense, racing an electric bike is very similar to present-day MotoGP racing, which must use the allotted 20-liters of fuel not only efficiently, but with least negative effect on engine behavior and rider style. In both cases, lots of software has been written!
