3 things you should consider before buying an electric bicycle


Nowadays Electric Bicycle has reached the heart of people specifically Indians as we already know its advantages compare to non-electric ones, but do we all know what it is exactly? How does it run on electrical driven?

Electric Bicycle (e-bikes) is bicycle with an integrated electric motor to reduce human power while riding the cycle . It will help reducing 30% human effort up to 100% (effortless) depends on choice. There few types of Electric Bicycle in the market. Most of them are ready-to-use or installed cycle, which we can directly ride on it as we purchased and non-electric cycle, which we can convert with electric conversion kit. E bike has 3 main parts that attached on it in order to give electric-driven cycle.

1. Motor

In an e bikes, the motor plays an important roles to give a different result. However this can be customized with the specification of each motor, the outcome still be not the same and satisfying. The motors can be hub motor and mid drive motor. Our bicycles use Brushless DC (BLDC) motor in rear wheels . In other hands, mid drive motor can be BLDC or PMDC (Permanent Magnet DC).

Hub motor is often preferred as a driven in an e bike due to its easiness to only pull throttle when we are going to ride in electric mode. This kind of motor are widely used in the market right now. It can be installed in the front or rear wheels, while most of e bikes put in on the latter. 

The advantages of rear hub motor are users will get pushing effect instead of pulling. It is considered safer when a rider tries to make sudden stop. While the front hub will pull a rider out from the cycle. Besides hub motor is affordable enough compare to mid drive. It gives a best output for an e bike beginner out of there.

2. Battery

First generation of e bikes used Sealed Lead Acid (SLA) battery with mid to high power on it. As technologies develop, this kind of battery is replaced by Lithium Ion/Polymer. The Lead Acid battery had also been used in submarine, solar energy storage, and automotive and traction industry before. It has advantages for its robust, tolerant of overcharging, and deliver high current. It also less costly. However it only has short life span, its slow and inefficient charging.

While The Lithium Ion battery has more advantages compare to former battery.

It is fast charging with efficiency near 100% even when discharge

The weight is lighter, more than half lesser of Lead Acid

Long life cycle around 5000 times compared to 400-500 cycles in Lead Acid

Environment friendly

Despite its cost is pricey, but it gives more benefits for any application.

Due to the facts that Lithium Ion Battery has taken over the place for decades and its superior specifications, GoGoA1.com had already set the plan to provide electric conversion kit with Lithium Battery on it. Also all electric bicycle under GoGoA1.com company are installed with the same battery. Furthermore, we still can find the application of Lead Acid battery on an electric bicycle in the market. The mid drive cycle can be installed with either Lithium Ion or Lead Acid depends on customer choice.

3. Controller

Basically, the controller can be pedal based and throttle based. The former means that the electric power will be activated when pedaling. Once the button is turned on, you can feel the electric force by only pedaling just like the way people cycling. It comes naturally. While the other hand, throttle based controller is way different. The source is in a throttle. Once the button is turned on, you can only pull the throttle to get the electric force. No need pedaling. It is suitable to ride on the road as there is no particular effort to push the pedal.

About US

We can’t stop the development but we need to find ways to lead speed and at the same time conserve our future. As an automobile technologist, I thought I could contribute to this thought by embracing e-mobility. KIMI is a step forward in this direction.
