I have seen a lot of off road type bikes on the main roads in foreign countries. Smaller, lightweight and easy on gas, they are a popular form of transportation. Rough roads are no problem and they are made tough. I can see this type of EV bike being a very popular form of transportation. Not sure of its popularity in the racing community though.
I saw some electric cycles road race as a MotoGP support race at Indy. Some were pretty impressive, some quite lame. It was a short race, too.
