That's the thing with electric motors, maximum torque nearly instantly and continuously.
Look at those electric bikes running at Pikes Peak, no loss of performance as altitude increases.
I'm looking forward to the electric motorcycles (not the HD one there making) but the sports bikes, they'll be stunning. Once the battery and charging technology gets there I'll be grovelling for another bike to put in the garage.
This ones limited to 150mph and does 0-60mph in less than 3 seconds, the bikes fast too....
