An electric bicycle (e-bike) is a pedal-powered bicycle equipped with an integrated electric motor that assists with pedaling, making it easier for riders to travel longer distances, climb hills, and carry heavier loads without excessive physical strain. E-bikes are typically classified intothreecategoriesbasedonthemotor'srole.
Pedelecs (Pedal-Assist):-
Thesebikesprovidemotorassistanceonlywhentherider is pedaling. The motor cuts off once the rider stops pedaling or exceeds a certain speed, making the experienceclosetotraditionalcyclingwithanextraboost.
Throttle-Controlled E-Bikes:-
Fig–2:Throttle
These bikes can be powered by the motor alone via a throttle mechanism, without the need for pedaling. The ridercancontrolthemotorspeeddirectly,offeringgreater flexibility.
Speed Pedelecs:-

Key Components of an Electric Bicycle:-
Motor:-
Fig–3:Motor
The motor, typically located in the wheel hub or central drive system, provides power to assist with pedaling. The size and power of the motor are measured in watts (W), withtypicalrangesbeingbetween250Wto750W.
