Key parts of the electric bicycle
An electric bicycle is a lot like a normal bicycle. The major difference is
the inclusion of a motor which provides a boost when desired. An
onboard rechargeable lithium battery supplies the motor with electric
power. The bicycle can be ridden using both pedal power and battery
power at the same time.
Controller
The controller regulates how much power is sent from the battery to the
motor.
Throttle
The throttle allows the rider to control the bike’s speed. It sends a signal to
the controller telling it how much power to send to the motor.
Battery
Electrical energy is stored in the battery pack. It is composed of many
smaller battery cells similar to that of a modern mobile phone.
Charger
The charger plugs into the electrical outlet and is used to pump energy
back into the battery pack when it becomes depleted. The more energy that
is discharged from the battery pack, the longer it will take to recharge.
Display
The display reads the battery’s voltage. This will give an approximation of
the battery’s charge state. The display may have other buttons to control
other functions.
Motor
The motor is built into the hub of the front wheel. When power is sent to
motor, it will began to spin, propelling the bike forward.
