Yes, especially with motor-assist. It will give you more power just when you need it.

+ Do electric bikes charge when you pedal them ?

No, this is not the purpose of having an electric bicycle. The purpose is not to have to pedal harder to charge the bike battery. Instead, the aim is to pedal less and make it easier for you to get around.

Electric bikes don’t have this feature because the effort that the rider puts in to pedaling can only go so far. Either the effort from pedaling is used to assist the bikes motion, or it could charge the battery. Unfortunately there’s no such thing as ‘free energy’ so you could image pedaling an e-bike that is also trying to charge the battery would make it very hard to pedal, as you’d be battling against the resistance of an added generator (not to mention the weight and cost) and also trying to assist the bikes motion. The most efficient use of the rider’s effort is to assist the motor in moving the bike, extended the range.

+ Can the battery be removed on the e bikes ?
