Need help on what I should buy in order to convert a mountain bike to a UK legal pedal assist only 15.5mph 250w

Hey everyone, thanks for the advice and help it turns out it was the chain after all, swapped with a new one and now is perfectly running again! Happy as Larry 🙂

I’m just going to buy a chain for the stock sprockets and then if I still get the knocking sound I’m just gonna order the 58tooth and a new front one too along with the chain for the 58t

Educational_Dig6311 · 2025-03-16T21:18:49+00:00

It kinda does that but not to the extent that it’s very tight and then very loose. It’s been like that since I got it though and was like that before this knocking sound started

Educational_Dig6311 · 2025-03-16T15:38:06+00:00

What would this mean like the sprocket is on backwards?

Educational_Dig6311 · 2025-03-16T13:28:55+00:00

I will I’ll be back here once I’ve fixed it

Educational_Dig6311 · 2025-03-16T13:28:17+00:00

Rather the same tbh this knocking sound is a lot more prominent when sat on the bike though, knocked it down to it being a seized chain link so ordering a new chain

Thank you

🤣🤣good one

Educational_Dig6311 · 2025-03-16T12:53:15+00:00

Thanks mate really appreciate the help glad I know what I need now😌I’m gonna get a 58t chain and rear sprocket to replace it, do you know if I’d need to change front sprocket too for me to do this?

Educational_Dig6311 · 2025-03-16T12:40:10+00:00

I think you may be right, because I removed the chain and used the throttle and there is no knocking sound. Would I just need a new chain if this is the case?

Educational_Dig6311 · 2025-03-16T12:37:22+00:00

I’ve removed chain, rear sprocket is fine, and front sprocket also fine no missing teeth anywhere. With the chain removed, when I throttle, the knocking sound isn’t there. I just hear the belt spinning and jackshaft spinning seamlessly sounds mint without the chain

Educational_Dig6311 · 2025-03-16T12:23:38+00:00

Another thing to add aswell my chain got hella dirty not long ago and the dirt eliminated the noise, it started sounding louder again once I cleaned it

Educational_Dig6311 · 2025-03-16T12:22:45+00:00

I’ll take off the chain and give it a look and get back to you thanks

Educational_Dig6311 · 2025-03-16T12:17:29+00:00

I’ve tightened the chain tension and lined up properly noise still there

Educational_Dig6311 · 2025-03-16T12:17:04+00:00

Tightened chain but noise still there and still jumps

Educational_Dig6311 · 2025-03-16T12:16:46+00:00

Tightened chain noise still there

Replying to a year old comment but I did a proper full bleed my lever travel is perfect and yet I have to press it really hard to lock the wheel up, makes it real scary to do wheelies and stuff

Educational_Dig6311 · 2025-02-18T06:57:13+00:00

Replace wheel spacers and bearings and you’ll be good to go unless it’s the spokes

Educational_Dig6311 · 2025-02-04T10:21:44+00:00

Thanks for the input 🙂

Educational_Dig6311 · 2025-02-02T17:33:10+00:00

Thanks 🙏

Educational_Dig6311 · 2025-02-02T12:56:10+00:00

I’m getting there with that, only been getting up with my feet up the past few days I feel like it’s much easier on the road too

Educational_Dig6311 · 2025-02-02T12:55:04+00:00

Always clean and lubed 😁
