They way you installed it will cause rain to drip into the motor and then everything will rust inside and probably the clutch will brake at first. I can tell you from experience. Better to use a longer cable and put the axle upside down.

I was about to post something similar, with the axle upside down and the cable going up as you say rain will wick along that cable into the motor ether shorting connections or causing rust, for this reason I always install with the cut in the axle facing down I also make sure the wire goes directly down about an inch and then loops back up to the frame where it is secured / zip-tied this means that any rain on the wire will travel down and drip off at the loop and not wick up into the motor

Hi Mels. The cable at the inner end of the hollow axle is blathered in black silicone at manufacturing from my experience, having had to dig this out to release the cable. I guess it’s a good idea to reseal this before putting the whole thing back together. 😉

There is a serious lack of ebike repair knowledge here in Ireland but like every new technology l'm sure this will improve. I went to a repair shop in Tallaght Dublin ( inner city scooters) with a damaged cable on my Engwe Engine Pro. They put in a new set of sensors for me and I highly recommend them. Big shout out to Dan the Man👍

Great video Dominic. My spindle came loose and knotted up the cable. I was going to solder joint all 9 wire externally, but was never comfortable with what would be the end result for a fixed wiring back to the controller. I've now found a new 9 pin extension lead 1.5 metres long. So I can cut off the plug end about 30cm or so and rewire wire this through the spindle as you show. Once I rewire the other piece of cable back to the controller I'll then have a convenient 9 pin connector joint to ease wheel and tyre service

Came looking for the tip about not removing the free hub screws! I'm trying to take them out right now not sure if I needed to. And boom one is stripped. Then some penetrating oil. A few minutes. One screw out. The other 4 not turning, feel like they're stripping. I'll quit now and put the one back in. I'll get the three screws and clip on the other side. And do it properly. Thanks

I damaged my front hub motor slightly (it sometimes turns off when riding and I have to reboot) due to the shaft rotating in the fork, very dangerous when the wire wraps and the wheel stops! The u shaped tabs spread apart over time (they were thin and weak), and the shaft was not restrained. I fixed by welding reinforcing plates to the outside of the fork. I would recommend rear wheel drive now, ha ha. I may have to take the hub apart if it gets any worse, thanks for a video to describe what to expect, it would be easier on front hub, and no gears to deal with.
@EQINOX187
@EQINOX187 3 жыл бұрын
I think part of your issue was using a front motor and the second was not using torque arms, front motors work well but forks are not really designed to take the load so can fail in one way or another and the usual point is the u shaped tabs as you call them as they can spread or round out if there the nuts are not sufficiently tight, this is why a torque arms are very important as it as an extra way to secure the axle in relation to the fork or frame and stop fork or frame damage in the event the nuts loosen or a large amount of torque tried to twist the axle in the U shaped tabs, even on the rear i would and still do use torque arms .

I've got the exact same problem right now and I can't find anyone to help fix it for me. I'm in London and run a small unfunded, nonprofit homeless outreach group delivering food and other much needed essentials to our friends on the streets, I do this on an electric cargo bike. But as you mentioned 1 of the forks cracked at the front and has in turn twisted the wires, I've managed to get the forks welded thankfully, however I still need to fix the motor if anyone can possibly point me in the direction of someone who can help please, as I can't do the outreaches as efficiently without the bike.

@dominicogallachoir4554
@dominicogallachoir4554 3 жыл бұрын
Hi Tom, it sounds like an issue with the cadence (pedalling) sensor. Check if there's a little disk near your bottom bracket with magnets embedded in it. I've a feeling the disk is a bit wonky, so the magnets are moving too far from the sensor at certain parts of the pedal stroke, causing the motor controller to think you've stopped pedalling and the motor to cut out. Try to move the whole magnet disk as close to the sensor as possible, without rubbing. And as straight as possible.

When you mention that you need cassete lock ring tool with decent size in the middle, how did you remove the original nut that is on the axle and holds it to the bike frame? When I unscrew mine it is still stuck on the power cable and can not be forced over the connector.

It might remove the 25km/h speed limit. However, it will also give you "speed sensor abnormality" and stop the odometer from working so I would not recommend. There are other ways to remove the 25km/h limit if that's what you want - See page 10 of the Bafang C961 manual.

Hi Dan. It's a long while, so I can't really remember all the details, but I do think the white wire is some sort of sensor - maybe for hub speed or temperature or something. Maybe try eBay for a harness. And yes, I think you could just solder in a new piece for the white wire instead of cutting the harness and re-soldering to the board.

hi Dominic great video you know your stuff i am in ireland too and was wondering if you can help i converted a ninebot mini pro to a wheelchair[ as you do] i had bad heart attack but something went wrong it showed error code 39 motor problem so tested both motor hall sensors one was testing perfect 5 volts dc to zero volts dc when wheel was turned but the other wheel was showing a dead short between the red and black testing down the cable into the motor , on opening it up two sensors where completely burned out so replaced all three with ss 41 , couldnt read what was on the old sensors they were too badly burned. the middle sensor has reversed live with the sensor output so looking at all three sensors the left and right one had the live on the right hand side and the sensor out put green and blue on the left , the yellow middle sensor was on the right and the positive on the left so I read that what people do is then turn the middle sensor around so as to make the writing ss41 face away from the stator to be just like the other two, built it back up now its bleeping error code 18 and the motor not sure if its both or one is shaking and on the app its saying motor shake ride with caution so was wondering could there be something else wrong , I did fit a second hand supposed to be working ok mother board , any help greatly appreciated thanks

Hi I have a new ebike kit wheel wont turn when any phase wires touch each other when not o bike or power connected when all set up wheel wont turn feels jammed thanks if you can help
@dominicogallachoir4554
@dominicogallachoir4554 4 жыл бұрын
Hi dave john. It's normal for the motor to be difficult to turn when you touch some of the phase wires together. That's because it's effectively behaving as a short-circuited generator (very stiff). On the other hand, if you connected the electronics properly and the wheel is jammed then it could be mounted incorrectly into the frame of the bike.

do you think if you disconnected the speed wire it would disable it
@dominicogallachoir4554
@dominicogallachoir4554 4 жыл бұрын
If you disconnect the speed sensor wire you will definitely get the Error 21 warning which will be annoying at least and causes some other issues with the system. If I remember right, I wasn't able to change the power setting once Error 21 appeared (only exception was by turning the bike off and on again). The motor may kind of work otherwise but this would be a very poor user experience

I stopped at about 3 minutes and 7 seconds into the video I'm sorry but I'm a mechanic and a bike shop and if you're going to change the cable you might as well change the halt sensors as well all you have to do is unscrew the two Phillips screws that are holding down the circuit board and you can access everything as long as you have some of the insulating paper that was originally there you can still reconnect the wires from underneath if you're going to reconnect the wires or resolder them on the top of the board you should cover it with a little bit of hot glue or some sort of silicone sealant and make sure that the top cover is not rub against any of the contact points of the wiring mind you but it's also necessary to use some silicone at the point where the motor cable enters the inside of the motor body and possibly a little bit on the outside of the axle where the motor cable enters the Axel from outside to protect from any water Ingress

This all depends on what's causing the problem. Is there damage on any of the parts? Are you getting any errors? Is the battery charging okay? You may need to do some experiments to figure out what's causing the problem.

Unfortunately, Bafang parts distribution is patchy. There are some sellers on Aliexpress that do a lot of Bafang/8fun parts, might be worth a try. I suspect your motor is sensor-less but can't promise.
