broken cable help

[billyboya]

Will this PCB be ok nealh as Ive gone and ordered it as I cant seem to fix old one.

 

[Nealh]

It's not the exact one but is similar, it shouldn't be an issue.

Ok many thanks Nealh will update you when it’s fitted

Hi Nealh just to let you know at long last after waiting 5 weeks the hall sensors pcb arrived today 12th march so will fit 1 and hopefully it will run straight away if not will have to use those learn wires. or do the combinations. which I hope I don't need to. will keep you updated later

not bad price 5 sets of pcbs for £13.87 much cheaper than in UK

 

[billyboya]

Nealh if you about, I have fixed the hall sensors pcb board wired it all up and it went 1st time. so well happy with that. didn't have to do the learning wires or do those combinations. I just have to fit all the proper anti- rotation and torque washers etc to wheel. I am only taking it for tests along a short road and back to test out a few times its not far if I have to walk it back But fingers crossed all testing will be fine this time.

hope you can view videos ok

and as always many thanks for your marvellous help plus others here too

 

[Nealh]

Well done, hope the road test goes all ok.

 

[billyboya]

Well done, hope the road test goes all ok.

Well I will now have rotation washers and also torque washers on axle plus that loctite 243 glue on the thread so hopefully that will be ok as can’t see axle turning again. But like I said will do just a few walking distance runs first. But I’m sure it will be ok

4 months been doing this lol. So it had better be ok

 

[billyboya]

Nealh if you about Im having a problem fitting the torque washers, as its making the chain far too tight. I have the rotation washers on ok so will they be enough 1 on each side. But its real hard to fit the torque ones

 

[Nealh]

The chain probably is too short then, it is imperative the torque arms are fitted otherwise the wheel will twist the motor cable again.

 

[billyboya]

Well this is what I have so far, But the chain is same as I have had from since I bought moped.

I have a washer on inside of spokes, and on the outside is a rotation washer plus a big washer then the nut. but how can I tell what size chain to get then, would that mean unlinking chain measure length

I think when i did have torgue washers on the axle was nearly to ends of drop outs so wont a longer chain be too loose

 

[billyboya]

Here are some images of torque washers, But I also have before those the ant rotation ones, so maybe its best to leave the anti rotation ones off as I cant fit those if I fit the torque ones 1st as the anti ones wont fit into drop outs then

I was watching some youtube videos on torque washers and see they use a ring clip

can anyone here recommend strong torque washers

Is it still too soon to congratulate you again billyboya? I'm amazed you stuck at it for so long! I'd have (carefully) torn it up into ickle teeny tiny bits to sell on ebay pretty much straightaway - that you stuck with it and saw it through to a successful conclusion is very impressive! By reading the great advice others have posted on this thread, such as the incomprehensibly patient nealh, I've learned useful things too.

 

[Nealh]

One needs to go back to #15 & #18 and fit those style torque arms on each side including the fixing bolt in to the tapped hole, the tabbed torque washers I in the main just a location/holding washer ( alfine geared hubs use them for locating and holding the axle in the correct position).
Once they are fitted then find a suitable chain that is long enough, the chain already on the bike is likely not the correct length as the torque arm/s were never fixed in situ.

Hi geurney thanks for your congrats. It means a lot. The reason why I have stuck to it, is because I don’t give up on things. And as I had spent money on a battery plus a few other parts. I wanted to get it fixed. It’s been like a hobby to me I’m opening my 1st electric moped shop soon lol. Billyboya electric moped repairs. What I’ve learnt here I will certainly know what to do next time if it goes wrong. I have been on this moped 4 months now. But a month well 5 weeks was waiting for those hall sensor pcb boards from China. Which I thought at £13.87 for 5 boards was cheap. As I saw same just 1 board for £22 what a rip off I thought.

I have to thank Nealh for his great help. He has taught me loads here. I never had a clue what phase or hall wires was or even how to remove the motor . Also. Matthewslack I think that’s his name who told me to join the 3 phase wires together at motor end

Hi Nealh so you are saying to fit the ones ERider sent me as I have ordered these from eBay as the ones from ERider seem too long which makes the chain too taught also with having a bolt in that hole is a bit impossible as don’t line up. But I think if I shorted them a bit then maybe drill new bolt holes in the drop out it should be ok also add some more chain links will help too

Im not sure if these will fit a 14mm axle

This is what ERider sent but don’t seem for this moped

Nealh. How do you lengthen a chain do you have to buy spare links and if so how do you add them. And lock them

 

[Nealh]

I would try and use the erider one piece torque arms, you already had one that was correct. The erider ones look ok to me from the pic, they need to sit direct on the drop out and then secure with a bolt.
The chain looks to be a single speed cycle chain, count the links as they come in various lengths/links .

 

[Nealh]

In #111 the torque arm isn't dead flat on the drop out /stay, you have the anti rotation washer (ARW) in between, this needs to be removed.

Don't forget some one had messed with the bike big time before you got it, so looks like someone omitted fitting the torque arms and may have fitted the ARW's instead. The ARW's may originally /probably weren't used and are just throwing a spanner in the works and are not required as the Torque arm's are all that are needed.

 

[guerney]

How many links is your Erider 15 supposed to have had originally billyboya? I've been googling for that info, but no joy. I did find a manual for another Erider model, which says there should be a small amount of slack in the chain (page 22), which may or may not be relevant for your bike. Might be worth asking Erider how long the chain is supposed to be, for your model 15?

https://eriderbikes.com/wp-content/uploads/2020/10/V7-Manual.pdf

Adjustment of chain
Loosen the rear axle nut first to adjust the slack of the chain. While adjusting the chain, the front and rear chain wheel must be aligned in a straight line. After adjustment, fix the rear axle nut. Lock the adjusting nut for final inspection to make the loosening distance between the centers of two chain wheels is 10 ~ 15mm.

Oh so those ARW are not required if I fit torque washers. What about those I have ordered from eBay I sent you a link won’t they be better. That’s if they fit a 14mm axle as those what ERider sent are not same as in the 11 and 18 images. Also they are a bit too long so need shortening a bit which I can do that’s why the chain is a bit taught. As you can’t move wheel back in dropouts to make chain looser
