About the Lithium ion battery
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 ion battery supplies the motor with electric power. The bicycle can be ridden using both pedal power and battery power at the same time.
The controller regulates how much power is sent from the battery to the motor.
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.
Electrical energy is stored in the battery pack. It is composed of many smaller battery cells similar to that of a modern mobile phone.
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.
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.
The motor is built into the hub of the rear wheel. When power is sent to the motor, it will began to spin, propelling the bike forward.
The gear shifter changes the ratio between the pedals and the rear wheel. It is used to find a more comfortable pedaling cadence under different riding conditions. The low gear is used for pedaling during starts, uphill or loaded riding. The higher gears are use when pedaling downhill or during faster riding.
The brakes use friction to slow the bike down. The levers on the handlebars control the braking. The brakes have an electrical switch which cuts the power to the motor at the moment when the brakes are used. This prevents accidental accelerations while braking.
The battery has a fuse which is used to prevent excessive amounts of power surging through the wires and damaging the electronics. When the fuse is tripped, it will need to be replaced.
Tire and Inner Tube
The tire is made of rubber and provides traction for your bicycle. The Inner tube, is a rubber tube inside the tire retains the tire’s air.
PSI (Pounds per Square Inch)
The PSI is a measure of air pressure inside the tire. It can be measured with a tire gauge. Pumping more air into the tire increases the PSI and
makes the tire harder. Releasing air from the tire decreases the PSI and makes the tire softer. Both over and under inflating the tire can have negative effects.
