Electric bikes are as diverse as any other vehicle in the world. So, often it becomes very difficult for a new buyer to decide the right e-bike. To ease this problem, here is a short guide to different types of electric bikes based on the motor system.
A motor is a vital part of an e-bike, so a rider needs to understand at least a little about different types of e-bike motors. Broadly, there are two major types of electric bikes, based on how a bike starts and controls the motor – Pedelec (pedal-assisted) and throttle electric bikes. Though it is only a generalized and rough division, it is rapidly growing popular in e-bike ranges.
Let us get to know about them in detail.
Throttle electric bikes
As the name suggests, throttle e-bikes offer some sort of throttle to the rider. It can be compared to the variable throttle switch on the handlebar placed on a motorcycle which manually turns the motor on and controls its power. A throttle allows a rider to take control of the bike when the motor turns on or off and use as little power as they require. It makes the bike easy to ride, be it pedal-only or motor-only mode. With the application of the brakes, power can be cut, and the bike can be slowed down so that the rider doesn’t get carried away when they wish to stop.
While deciding on the types of an e-bike, catering to your requirements, one of the important things to consider is – the type and degree of control you want over the motor. If you have to ride the e-bike in different road conditions and terrains, or you are looking for an all-inclusive control for quickly switching from pedal-only to motor-only modes, it is advisable to pick a throttle electric bike.
Pedelec electric bikes
Pedal-assisted e-bikes, or commonly referred to as pedelecs do not contain throttle to control the motor directly. Instead, these e-bikes use pedal assist system to respond to rider’s pedaling. When the bike is run, it activates the automatic motor assistance to assess how much power the rider is applying to the pedals and add it get the adequate help when required.
There are two types of pedelecs:
Torque sensing Pedelec – It requires little effort to operate as the boost system automatically responds when pedaled. It assists from a standing start as a lot of power can be generated with a strong push. It also requires sensors to monitor pedal rotation, road speed, and force.
Rotation sensing Pedelec – One sensor is used to check how fast a rider is pedaling forward. Such type of bike includes the motor system that turns on or off fully according to ot the level of assistance the rider has set once they start pedaling for a few seconds.
Hub electric bikes
Based on the location of the motor e-bikes can be grouped into two major types. Hub motors are located in the wheels while the mid-drive electric bicycles consist motor located on the frame.
There are two types of hub-motors available in the market – direct hub motors and geared hub motors.
Direct drive hub motors are known for their larger, faster and durable style, but they have less torque. They are also known for a bit of drag which results in less efficiency. Geared hub motors are smaller and lighter and have great torque. However, they have less speed than direct drive. E-bikes can contain hub motors located, either on the front or rear wheel with different benefits and drawbacks.
Hope this guide would help you choose the right type of e-bike. Have a great ride!
