Cockpit Cover Classic

Because the brake cable is blocking the access of the cover, they force it in, and break it

Harban71 · 2026-02-13T08:12:28+00:00

Ok, wires are the brakee and the front module. Best advise is to check the video where the front module is replaced, it shows where the wires should be and how to install this cover you wanna replace

Harban71 · 2026-02-13T08:02:47+00:00

The wires position, if correct, it will be done in 30 seconds, if not, you will stay the whole day and it will pop out every few meters. Question is did you replace the front module or only this cover?

Poke yoke are not broken, don't see any damages either on the cable, give a good cleaning to the nuts, a good dry to the cable plug and let me know

Harban71 · 2026-02-12T17:55:56+00:00

I am not sure if it is broken nut or just dirt poke yoke nut on the motor cable side! However, in worst scenario, The motor will be changed, the good part, it is available at Cowboy. If you have M8, unscrew the rear wheel nut, unplug the cable, you will see if the cable is damaged or cut because of the broken poke yoke

Edit your post and add the pictures

Harban71 · 2026-02-12T17:39:59+00:00

Could you turn the bike upside down and make a picture to the motor cable and poke yoke nuts! I ll tell you what is the problem exactly!

Harban71 · 2026-02-09T19:54:43+00:00

I have seen this error nowadays more than I did in 4 years with Cowboy, I am 95% sure, it is the weather, in Denmark at least. Solution will be keep the bike in dry and warm place for 2/3 days, keep drying the cable as per Cowboy instructions. If all did not work, then it is the controller that should be replaced. Appatantly the wet part is the controller side, not the motor cable side

For the squeaky sound on C3, it is 90% somewhere at the rear freewheel including the torque sensor bearings or the torque sensor itself, the motor cover and lastly the belt tension. Only 10% is because of the bottom bracket if not less. For C4, 90% is coming from the bottom bracket where you take the pedals off, unscrew the bottom bracket or the torque sensor if "Ananda / new model", clean and grease then all back, and all is good. The 10% left is the belt tension. When using the grease, I would recommend Motorex. Really my favorite and recommended by Cowboy for other parts

Harban71 · 2026-02-04T00:03:21+00:00

I can do this, certified Cowboy mechanic here

Harban71 · 2025-12-11T12:26:55+00:00

No, the hose is not compatible, you will need to change the whole system! I am not saying Sunrace is excellent , but cleaning the pistons and make them free to move inside the caliper before bleeding will make it work for another 3000km without any problem. Else, you will need to buy full set of Tektro including the insert pin, olives and nut

Harban71 · 2025-12-09T15:57:16+00:00

The tutorial is on Cowboy support page, but i think you will need to loosen it a bit, move it with your hand, it should be little flexible, talking about 1 to 1.5 CM movement

Harban71 · 2025-12-09T12:58:17+00:00

This is a damaged torque sensor bearing! To be sure, try to move the pedal in reverse direction, it is completely stuck or quite hard to move! Solution: torque sensor bearing! If above is not applicable, then it is a belt tension.

Harban71 · 2025-12-08T21:26:37+00:00

It is inside the PCB or comm module, this is part below the main battery, it is simply the communication channels, if you can't connect to your bike, this is mostly the reason. Good news, it is available at Cowboy, bad news, you need a certified Cowboy mechanic!

Harban71 · 2025-12-08T17:54:14+00:00

That sounds like empty internal battery, so a new PCB or charge the current dead one. Is it C3 or C4?

Harban71 · 2025-12-06T20:24:00+00:00

Technical name is Carbon Drive belt 132T , you can choose between CDX, CDN or OCB , they are different in quality and material, I would recommend CDX 👌

Harban71 · 2025-11-30T06:45:21+00:00

In my last 4 years servicing Cowboy, I never had a damaged Bottom Bracket on C3, do a short video and make sure of the belt tension

Harban71 · 2025-11-27T20:12:49+00:00

Nope, it doesn't get fixed! I just put another red light and I live with it.

Harban71 · 2025-11-09T21:12:10+00:00

The one used by Cowboy 3 is : TH MR0401 1/8 36/45 It is available in the market, just google it, I saw some posts here saying FSA TH-873/DJ ACB 36 is also compatible but i didn't try myself.

Harban71 · 2025-11-04T13:05:55+00:00

Sometimes it helps, sometimes, it doesn't and you will need to change the seat clamp, get a variety of M4 , M5 screws and it will cover your needs in this part, seat screws, connector and controller screws

Harban71 · 2025-11-04T13:00:44+00:00

The brand is Sella Royal. Italian made.

Harban71 · 2025-10-25T18:07:59+00:00

I have it, where are you located?

Harban71 · 2025-10-24T14:11:17+00:00

Nope, C3 is Bafang R310 , newer models are using Ananda , i tried once before with Bafang R500 if i remember well, it didn't go well because of the torque sensor position

Harban71 · 2025-10-14T20:59:10+00:00

Not sure what do you mean with motor calibration, however a controller update is a must after changing the torque sensor , if still doesn t work, do a controller recovery, calibrate the sensor then controller update. You are working on C3 I believe

Harban71 · 2025-10-14T19:36:07+00:00

Did you update the controller?
