Hi Louis & All other readers,

I got the front wheel and rear wheel versions from Louis last year. For the front wheel version, last year I tested it and found that the third gear (the H gear more preciously) was not working. I wrote to Louis and he gave me several suggestions. But I still could not get the H gear working. And Louis's final suggestion was to send the motor back to him for testing. I did not send it because of some reasons.
This year I have time and so I tried it again recently. I found the H gear is not not working but working in a strange way. The gear H only kicks in when the M gear reaches it maximum speed. So I would like to ask Louis if the H gear is designed in this way. And if any reader gets a more normal H gear. Here is the details. When it is in L gear, the speed changes gradually from 0 to a maximum speed of about 26 km/h as I twist the throttle. When I switch from L to M gear and with the throttle holding at a certain point, the speed changes to a higher speed. (This is what I expect when switching from a low gear to high gear just like driving a car). The maximum speed in M gear is about 35 km/h. When I switch from M gear to H gear with the throttle holding at a certain point, the speed remains unchanged. (that was why I complaint to Louis that the H gear was not working). But as I continue to twist the throttle so that the speed reaches to the maximum of the M gear (which is about 36km/h), then the speed suddenly (instead of gradually) jumps to about 45 km/h. There is no control of speed in between 36 and 45km/h. That means after 36km/h, you can only have 45km/h. I will consider this is not normal. Also, this is very dangerous because of the sudden increase of about 9km/h and so I did not try that on ground (I only tried it with the front wheel running freely not touching the ground). Hope Louis and all reader can give me some comments on this.

Recently, I also tried to install the rear wheel kit. I got the wheel installed and all the wires connected. As I twist the throttle, the wheel turns but with some abnormal noise, no matter which gear it is on. (There is no such noise from the front wheel kit). I have checked the installation. The wheel is not touching the bike frame or anything. When the wheel is turn manually, there is no such noise. I am suspecting the noise is from the gears inside and so I dare not twist the throttle fully. You comment is highly appreciated.

Hi Mr. Ho,

nice to see you here, the problems you described sounds have nothing to do with the motor, but the problem of the coonection between motor & controller.

By motor & controller there are 8 wires, 5 thin of them is called haul wires, while 3 thick of them is called phase wires. When these wires are not connected correctly there will be similar problems of what you described.

Below is a procedure of how to detect correct wires connection.

How to Check this connection?

1: Remain the connection of motor 5 wires with controller 5 wires unchanged; (so called haul wires)

2: By the controller and motor there is still another 3 wires called phase wires;

3: Connect motor phase wire and controller phase wire casually, such as green with yellow, yellow with blue, and blue with green, then applying throttle to observe if the motor could spin;

4: If the motor doesn't spin, then change the phase wires connection casually, then apply throttle to observe if the motor could spin;

5: When the motor could spin under one connection, but this spin is abnormal, such as very noisy, very fast, or very slow, then follow the enclosed " phase wire order detect".

In the enclosed file, we take it as an example, that is under green--green, yellow-yellow, blue--blue connection the motor could spin but very noisy, then we remain the motor's phase wire sequence unchanged, but change the controller's phase wire in such a order:

The middle & bottom wires go up, the top wire drops to bottom.

Every time after you change the connection, apply the throttle to observe if the motor could spin normally and if 3 speeds works normally;

6: If the motor spins normally but it spins reversely during the procedure "5 " ,

then we need to change the connection of the haul wires of the motor and controller. Just change the "green" & "blue" haul wires.

For example, if original connection of the haul wires is

green--green
yellow--yellow
blue--blue

Then change it to

green-blue
yellow--yellow (unchanged)
blue--green

Then repeat the procedure of 3,4,5 until you find out the correct connect wire order.

Please try it one by one, i.e first front wheel kit, when you succeed, then rear wheel kit.

Just note please the controller for front wheel kit is different than controller for rear wheel kit, donot mix them.

Above is a simple procedure on how to check out the connection, if you do have problems in this you could just send back this 2 controllers then we will check it for you. Remember please you purchased another controller supporting ebike analyst, it doesn't works with throttle 3 speeds.

Waitting for your further reports.

Thanks,

Louis

Hi Louis,

Thanks for your prompt reply.
I will sure try your suggestion and post the result after trying it.
But how about my problem with the H gear? Do you mean the switching of phase wires may also solve the problem?

Hi Ho, yes you are right, when controller is not connected with motor properly, not only the motor will be abnormal, the 3 speeds will be abnormal too.

Just try this and this should be solved.

Thanks,

Louis

Hi Louis,
I have tried your suggestion with the rear wheel kit. I have tried every combination on the phase wires. And I can get the wheel spins forward smoothly without any abnormal noise. The wires combination are: motor phase wire Yellow - controller phase wire Yellow, motor phase wire Green - controller phase wire Blue, motor phase wire Blue - controller phase wire Green. But the H gear also has the same problem of the front wheel kit. Do you have any more suggestion to me to solve the H gear problem?
Thanks!

Hello Ho,

please try same procedure with the front wheeler and let us know what happen.

Thanks,

Louis

I have tested the front wheel kit as well. Here below are the details of what I found.

Front wheel kit:

Motor phase wire Yellow - Controller phase wire Yellow
Motor phase wire Green - Controller phase wire Green
Motor phase wire Blue - Controller phase wire Blue
(that is the original connection - no switching of phase wires)
The wheel spins normally.
L gear speed: 0-26 km/h
M gear speed: 0-36 km/h
H gear speed: 0-36 km/h, but speed jumps to 42 km/h suddenly when 36 km/h is reached (no speed in between 36 & 44 km/h)

Motor phase wire Green - Controller phase wire Yellow
Motor phase wire Yellow - Controller phase wire Blue
Motor phase wire Blue - Controller phase wire Green
The wheel spins smoothly but in Reverse direction.
L gear speed: 0-32 km/h
M gear speed: 0-42 km/h
H gear speed: 0-42 km/h, (there is no difference between M & H gears)

Motor phase wire Green - Controller phase wire Blue
Motor phase wire Yellow - Controller phase wire Green
Motor phase wire Blue - Controller phase wire Yellow
The wheel does not spin and there is no noise.

Motor phase wire Yellow - Controller phase wire Yellow
Motor phase wire Green - Controller phase wire Blue
Motor phase wire Blue - Controller phase wire Green
The wheel does not spin and there is abnormal noise.

Motor phase wire Blue - Controller phase wire Blue
Motor phase wire Yellow - Controller phase wire Green
Motor phase wire Green - Controller phase wire Yellow
The wheel does not spin and there is abnormal noise

Motor phase wire Green - Controller phase wire Green
Motor phase wire Yellow - Controller phase wire Blue
Motor phase wire Blue - Controller phase wire Yellow
The wheel does not spin and there is abnormal noise

Please note only the phase wires have been switched around and the haul wires have not been switched.
Also, the test was done with wheels not touching the ground (that means the wheels were without any external load).

Here below is the more detail findings regarding the gears of the Rear wheel kit:
L gear: 0-21 km/h
M gear: 0-31 km/h
L gear: 0-31 km/h, but jump to 35 km/h suddenly when 31 km/h is reached (no speed in between 31-35 km/h). But occasionally, you can get 42 km/h for 0.5 second and then back to 35 km/h. I got one time holding the throttle at a certain position and can keep the 42 km/h.

Hi Mr. Ho,

thanks for the response, could you please change the controller and repeat these procedures again?

Why we asked this is the controller supporting the front wheeler or rear wheeler is different setup (software), so when the controllers are mixed there will be problems.

When we packed the kits we put controller with related kit in one carton, before the package we also tested each kit and it works with no problems. I guess you might mixed the controllers.

Anyway if these problems still happen, please pack this 2 controllers and send it back to us, we could check it here in our workshop.

Thanks,

Louis

Hi Louis,
I have switched the controllers. The results are just the same for both front wheel and rear wheel.
Where should I send those controllers to?

Hi Mr.Ho,

send back the controllers to our address

Fusin Motor Sports Co., Ltd.
1# WeiXiang Cangchu,
Feihe South Road, Hefei,
Anhui, China

Phone: +86 551 2829206

we will check if the controllers are broken and will fix them.

Thanks,

Louis
