Bafang clutch

[Tortus]

Hi.
Can anyone tell me if I can get a clutch for this motor please.
Its off a Carrera Crosscity, Bafang 250w rear wheel.
Ive looked everywhere (I think)
Please help if you can.
Thanks.

What is the teeth count of the two stages .

One needs to define the actual hub model number.
Though the clutch say's G110 250D , there is no such hub model number.

One could send a pic of it to Topbikekit to see if they can supply a clutch.

One is likely to find it nigh on impossible to find them for sale.

Thanks for the info, I need to remove the clutch part to count the splines. I will try and borrow a 3 jaw puller this week and count them and get back to you.
Thanks.

If I cant get one is there anyway I can fix it, maybe soak it in degreaser that's if it is not mechanically destroyed inside.

What's wrong with it ?

If you can build a wheel, you can get either a MXUS XF08C or AKM100SX motor complete from PSWPower for not much more than what you're going to pay for just a clutch. The XF08C id 280rpm at 36v and the AKM 100SX is 201 rpm at 36v. They list it with an easy-peal label as 350w, though nobody would believe that it is 350w because of its small size.

The clutch turns both ways. I thought they would only turn the way the arrow points.
I bought it 2nd hand and when I tried it out there was just an awful noise from the motor. I thought the nylon teeth had stripped but they are ok.
I have watched a youtube video of a guy (Grin technologies) who welded the clutch so it did regen braking.

Thanks I will have a look.

I don't think I could build a wheel, never done one before.

That's the same as many other guys on this forum, but we all had a go and got success - very satisfying! I've built about 20 wheels now. I do it on my lap while watching a film.

I have sent them an email with the pictures, fingers crossed.
Thanks for the info.

I doubt that one will be able to find them tbh, better off buying an AKM hub for which we know the gear sets are available.

Cheers, will it work with all the electrics that are already on the Halfords Crosscity?

 

[Nealh]

If the connector is a std nine pin Julet then yes. All of the AKM's use a two stage gear set so internal hub gearing won't be too dissimilar.

Great, thanks for that.
What would happen if I welded the clutch so it was always in drive?
I suppose when I stopped pedalling the motor would act like a generator and slow the bike down. but would it also give it regen?

Try working some 3in one oil down into the clutch and wiggling it back and forward. Sometimes it works.

One won't see any benefit from regen on a bike.
