It is most used motor in E-bike with light weight, cool looking, reliable and cheap. It uses planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel along with Hall Effect sensors, pass sensors.  Motors of an e-bike are placed on the hub or between pedals.

It is the main part of the E-bike connected to all other parts such as batteries, motors and throttle. It is used to collect input information from devices connected to it and send the signal in various voltages to the bikes, motor hub. There are different types of controller system available for E-bikes.

It is a kit which is used to convert regular bicycle into an electric bicycle. This electric bike conversion kit comes with a Li-ion battery pack with charger, Motor hub, complete wheel set, motor-throttle cable system, cabling zip ties, that is removable and portable. The e bike conversion kit can be completely customized based on your requirements and usage patterns.

 PAS stands for Pedal Assist System.  PAS consists of magnetic ring attached to crank arm or spindle PAS sensors used to detect the speed at which cranks are turning. The main benefit of PAS on an E-bike is that you can get power assist without using the throttle. A PAS controlled E-bike will usually have a control button on the handlebars to set the assist level, so you can still increase or decrease the motor power while riding.

Hall Effect sensors are used in hub motor to identify the presence of magnetic field also it is used by e-bike controller. Controller needs to know the position of motor at every point. It works on the signal strength coming from haul sensors if the strength is high that mean that one of the motor magnets going right past it. When signal strength is low means motor magnet has already gone past.

It is motor which is closer to the centre of bicycle and transfer the motor's power to the rear wheel via the bicycle's chain drive, mid-drive motors allow the use of true torque sensors for pedal assist systems, which regulate the motor power based on how hard you push on the pedals as measured at the crank.

Batteries are used to give energy to the motor E-bikes uses various types of rechargeable batteries like Lithium Batteries, Nickel Batteries and Lead batteries. Most E-bikes takes 2hour to 6 hour to fully charge E-bikes come with bay in order to connect the battery to bike Some e-bikes come with a feature that enables you to recharge the battery while you are riding the e-bike.

To charge an electric bikes battery charger is used , for charging the battery  remove the battery pack from the bike, make sure the battery pack switch is turned off, place the charger that comes with the e-bike into a mains outlet, connect the charger to the battery pack and then turn the plug on.

Charging cables used to recharge the e-bike battery easily and safely. The innovative and intelligent charging cable makes it possible in combination with bike-energy charging stations The unique charging cable from bike-energy is handy and light-weight.

Rim is the outer edge of a wheel holding the tire. Rim is important because it rotates around roads that are called arcs. Rims provide leverage and reduce friction when vehicle is moving.

Spokes is used for transferring the normal force to the hub along with maintaining the circular shape of wheel. The spokes to the bicycle increases the moment of inertia due to the increase in the distribution of mask.

Freewheel is a device which allows motion in only one direction. In the case of a bicycle, it allows the chain to transfer power only from the pedals to the wheel, not in the other direction. In a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft without a freewheel the rear wheel drives the pedals around.

Disk brakes are brakes that use calipers to squeeze pairs of pads against the disc or rotor to create friction. Disc brakes contains caliper which is used to squeeze break pad, brake pads squeeze the rotor instead of wheel, rotor is mounted on hub. In this system force is transmitted hydraulically instead through cable. Friction between the pads and the disc slows the disc down.

Rack is hardware component which is used to hold hardware modules, in E-bikes racks are used to hold batteries.

E-brake means emergency brake which is used in to keep the vehicle securely motionless when parked. In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. It is secondary braking system installed in motor vehicles E-Brakes are not powered by hydraulics and are independent of the service brakes used to slow and stop vehicles.

Brake levers are the small metal levers mounted on your handlebars that connects to the brake cable and thus operates the braking mechanism. The brake lever uses hydraulic fluid to transmit the force from your hand to the brake shoes. The handle presses a small piston that applies pressure to the fluid in the line, this piston is larger the force is multiplied at the wheels at the wheels, a larger piston squeezes the pads onto the disc.

E-bike contain ON/OFF switch for various applications. This switch is plugged-in between battery and controller it has remote ON/OFF button which can located anywhere on your E-bike.

Display of an e-bike is generally placed on handlebars which is easy to reach with your hands and your eyesight E-bikes displays are come in different variants some of the displays uses button.  The buttons are very easy to reach with the left thumb, without need to move the hand from its normal position these display shows the parameter like pedaling cadence, watts delivered by motor, estimate of the available range in miles, and more.
