Many E-bike fans sent us such an enquiry: May I convert a double (F&R) motorized wheel to my bicycle? Recently we have done such a test to convert F&R double hub motor to the bicycle.
The whole conception of double hub motor conversion as follows:
Which problems should we think about before we get ready to convert double hub motor to the bicycle?
a).Whether 1 battery can supply 2 hub motors?
b).Whether 1 throttle can operate the F&R hub motors well at the same time?
c).Whether one pair of brake handles can control the F&R hub motors?
As we all know, every hub motor with one single HALL working system, there is no doubt we have to use two controllers while convert the F&R hub motor to the bicycle.
So, the next problem lies in how to maintain the simultaneousness of the running and the braking for the F&R hub motor.
So, the solution to the above problem as below:
Material Preparation:
48V/20AH pingbattery *1
48V/1KW hub motor *2
48V/1KW controller *2
Brake handle *1 (L&R)
Throttle *1
Bicycle(GIANT ATX690) *1
1) How to fulfill both controllers connect with one battery?
We split one pair of Anderson pole into two pairs (Side B) first, and then connect side A to the original battery output Anderson pole.
2) How to fulfill both controllers connect with one throttle?
Similarly we split the black connector of the throttle signal cable into two.
3) How to fulfill both controllers connect with one pair of brake handles?
We split the white connector of brake handle cable into two.
4) The overall look when double hub motor conversion completed.
Finally, we get a conclusion as below:
* We drive at a fast start, and the top speed can reach 62KM/H on the street road.
* We have to install both same type hub motor to ensure the F&R motorized wheel drive at the same running circle. However, another new problem following, it’s too hard to be controlled the bicycle at the turning because of the same speed of both wheels. So next, we should make a great breakthrough to realize the conversion of double hub motor.
* Honestly, we don’t suggest you to try double hub motor. It’s too hard to be controlled
* Thanks in advance for your attention. Time permitted, I’ll constantly upload some more pictures &videos later.

Now I want to add a little equipment to limit the speed of the rear motor when I turn right/left.
A hall sensor will tell the rear motor controller to limit the electric current just like this:
