In this post, I will give you a general idea about what you mainly need when you convert your regular bicycle into an electric bicycle.
The first component you need is the motor. Normally, it ranges from 200 watts to 1000 watts. While most electric bicycles don’t need a bigger motor than 500 watts, since the law sets the maximum speed at 25km/h for electric bicycle. Modern electric bikes have motors built into their wheels. For example, brushless hub motor have a longer life expectancy (compared with magnetic brushes) and it is the bottom bracket motor. In other words, it turns the pedal instead of the wheel, so the rider feels a little more in tune with the motor, rather than feeling pushed or pulled by an external force.
The second component is the battery. In the last ten years, the most common battery used in electric bicycle is Sealed Lead Acid battery. This is the same battery in a lawnmower, golf cart, or go cart. Due to the need of lighter battery and longer range, Lithium batteries come to the stage. It can run for 20-30 miles on a single charge.
The last component is control unit. If you don’t want to pedal at all, just add a throttle. If you don’t want to drain battery quickly, pedal-assist control is an option. For instance, if you select “MODE 3”, you will get 50% power from the motor.
