Bet one thing won't change though. Bikers will still be at a greater risk than car drivers. Will we even hear them coming!Be careful of those figures. You can do some simple sums. You need about 12kW to run a medium sized, medium streamlined motorbike at 70 mph, so a 20kWh battery will last for about 90 minutes, so around 110 miles as long as you don't have the wind against you.
