January 17, 20224 yr Motor cable replacement is never easy. In the video he may have made the pulling through tougher by not lubing the cable or the hollow axle, grease is not good and needs something super slippy. For this I would use an everyday item found in the fridge, spread used on bread. How to replace a damaged cable harness in an ebike hub motor - Bing video

January 17, 20224 yr gotta admire your staying power with this project, if that moped was mine it would of been swimming with the shopping trolleys in the canal a long time ago
January 17, 20224 yr Author gotta admire your staying power with this project, if that moped was mine it would of been swimming with the shopping trolleys in the canal a long time ago Well what's the point in dumping it, when I have paid out all that money, as it was going ok, except when it slowed down, and its not the battery, or controller, as both been replaced. I'm now on the last stages of it the motor. new cable , new battery power lead, not a IEC plug no more but a deans cable, a new throttle, bingo all working again fingers crossed. I'm no hurry as too cold to ride it this weather anyway Plus its all knowledgeable as what I've learnt about the moped so far will be handy if I need to repair again Edited January 17, 20224 yr by billyboya
January 17, 20224 yr The only thing I find strange is in other threads you say it was 39km/h capable but e -rider only ever claimed it was 25km/h capable for the 15 model so that it complied with pedelec law.

Yes I agree and yes it did say on display 39 Km/h. But this motor has been altered as the previous owner. Not the person I bought it off. Had added it seems a extra wire to motor. Although it wasn’t attached to anything. But there is a plug on old controller which I never plugged in anywhere which has a connection from brown wire back into same wire where it plugs in or where it’s supposed to. I did read on YouTube someone doing that to increase speed. Also the power lead on moped is broke now as when trying to remove freewheel I had to press the tool tight to lock it in the 4 groves to undo it. So wires got cut so had to cut off cable. But I now have a problem getting the side case off so I can remove old wires ready for new cable. I have ordered a 6in gear puller as my old 4in one was not long enough so I hope it will come off ok as if not I’m stuck Yes I also thought of using butter from fridge as that's slippery But need to access wires inside 1st to see what's what Edited January 17, 20224 yr by billyboya

January 17, 20224 yr I'm not sure you can pull that off any more ? Otherwise the bloke at GRIN would have done so to make the job easier.
January 17, 20224 yr Author I'm not sure you can pull that off any more ? Otherwise the bloke at GRIN would have done so to make the job easier. Well there is no way I can access the wires inside. but not received 6" gear puller yet its arriving today so will try that. maybe that man on grin didn't think of removing the side cover. I mean look at him using his feet to pull cable through not very pro is he if anything he has stretched the cable. like you said some butter will make cable slip through I wont want him to fix my moped motor.
January 17, 20224 yr Author What a idiot I am a bloody 6in gear puller is way too small I should have measured side plate 1st it’s 9 1/2in wide. So it’s 10in I need this dam moped is slowly getting close to being dumped Lol. Grghhhh

You can't put the puller legs on the outside of the casing, it will either bend or break. TBH, I can't see how it's gonna help removing the cover as the cable exits behind that rivetted steel plate. Edit. Looking again at photo, I'm not sure you can strip this down any further. I think maybe the outer casing and the steel inner plate are held together by those rivets. Have a peek through the cut outs in the plate and see whats behind the rivets. Edited January 17, 20224 yr by wheeliepete

No you are right as the wires on opp side of freewheel Need to be cut. Like he does in that grin YouTube video then I can see if I can. Grip all those loose wires with a pair of pliers. And pull through freewheel side. Then thread new cable through. But only trouble is I don’t have a clue what wires to cut. Nealh was also right about that freewheel side case stays on. As in that grin video his is left on. I’m so grateful to you all for telling me this as I would have probably like you said crack casing. btw that unattached wire must have been problem as it just pulled through so obviously was broke that’s why wheel didn’t spin
January 17, 20224 yr With you hub the cable end exit in the hub can't be seen and so far the hall sensor's aren't visible. Edited January 17, 20224 yr by Nealh
January 17, 20224 yr Author With you hub the cake end exit in the hu can't be seen and so far the hall sensor's aren't visible. I’m very confused what’s cake and hu Can you repeat please are these the sensors but they seem to be on the freewheel side Edited January 17, 20224 yr by billyboya

I have checked behind the rivets and there isn’t anything but can see the wires now when I shine a torch behind inside case. So will case come off then if I replace freewheel then use gear puller to get case off EDIT: Well I’ve attached the freewheel and now using gear puller and it does seem to be coming off well slowly as I can see it’s moved so will try a bit more tomoz but slowly Edited January 17, 20224 yr by billyboya

If you have watched the video of cable replacement, you can see that you need good access to the axle where the cable enters the motor on the inside and I can't see removing the outer casing is not going to give you this.

Well by removing case it will give me more access to the wires and where they go well case has come off ok and now can see the sensor and phase wires Edited January 17, 20224 yr by billyboya
January 17, 20224 yr If you do try to pull a new cable through, then something like this might help: https://www.screwfix.com/p/ideal-yellow-77-wire-cable-pulling-lubricant-950ml/44462
