Electric bikes and motorcycles are treated very differently by the law. Motorcycles are liable for road tax, insurance, and must be registered with the DVLA. A driving license is needed for a motorcycle which also implies an age limit. With an ebike you do not need a driving license, it doesn’t need to be registered or insured and you don’t need to pay road tax. Ebikes are treated the same as other bikes.
Ebikes do not do the same high speed as motorcycles. Regulation limits the speed at which electric bikes will provide the rider with assistance. When an ebike reaches the speed of 15.5mph ebikes are required by law to stop providing power.
Like motorcycles, ebikes can slip down the side of traffic however ebikes have the added benefit of being able to skip onto cycle lanes, cut through parks and along nature trails. A motorcycle is restricted to roads.
With an ebike there is no need for a parking space and they can be carried on to trains and buses ready for you to explore new areas with minimum fuss.
