e-bikes
An e-bike is a bicycle with an integrated electric motor which offers propulsion assistance to a rider as required. This makes commuter riding far easier as the battery can assist up hill riding and riding long distances. Most electric bikes use lithium-ion battery packs, which are rechargeable via a standard power socket. Most e-bikes will have one battery system on board, however, some touring and commuter e-bikes are capable of taking two, even three battery packs at a time.
