You're right, that's it

You mean on this new bike? It's dark at the minute but I'll try in the morning. It's a generic torque arm and only on the one side - I could attach it to the brake mount, but on the other side there's nothing to mount anything to. Luckily we have just had an engineering firm move into the unit...

Yeah it was the clone. I cant even find the frame after a quick search on google now either. Main reason I went for it was because it was cheap. But after 6 months it started rusting in parts and after the crash it retired to the shed.

Hi over the years I've owned a couple of ebikes - I worked 25 miles away from home so started with a BBS02 Cube hardtail, the drive failed so built another one and that went too. So I decided to scrap the kid drive idea and bought a cheap DD hub and fitted that..then bought a EEB clone frame and...

I have this frame - or at least one that looks exactly like it, it's not an EEB one or EM3EV one, but is holding up pretty well (survived a few knocks!). It is steel construction, I bought off a guy advertising on here and paid $350 shipped which I think is a bargain...

Last month I got knocked off my bike by an old man that wasn't looking where he was going. My bike came down with a crash and wrecked the motor. I would like to fix the bike up because I enjoyed riding it, although have relocated so don't need it to do the 25 miles that it used to to get me to...

I'm having this problem at the moment too. I had the same issue a while back too - back then it was a water ingress issue and the hall wires were shorting against each other. This time though it's intermittent and was not easily identified - and as someone said in a previous post is down to a...

With the nights getting darker I've noticed that my cheap front light just isn't cutting it. I've seen some much better options on Amazon and Ebay but they come with their own (seperate) battery packs. An example is one that is 7.4V 8000mah. Call me lazy but I'd like a solution whereby I can...

Turns out it wasn't the solder joint after all - that part was relatively clean. The actual male bullet connector was rattling around inside the female part - it wasn't a good connection at all. There were broken bits of metal in there and everything. It doesn't surprise me it failed. It's...

I understand direct connection from a performance and reliability point of view, but wouldn't this create a nightmare regarding maintenance? I might give that a go... I don't fancy breaking down half way home... 13 miles with only one gear and a 40kg bike doesn't sound too good. I might hard...

My new build has been running smoothly for about 3 months now, but on the way into work today the bike intermittently lost power, the voltage indicator showing a temporary (2 second) drop in voltage. I made it into work and had a quick look around the bike and it appears the problem is from a...

Now that you mention it, the voltmeter that I have came with a large shunt that I've placed quite close to the controller and could be 'grounding' against the frame. Is this the sort of thing that can cause this problem?

I'm 95% through a new project of mine - my battery is an 18S 24Ah Lipo pack and I've just wired a new connector to a brand new 75V Li Ion charger. Plugged the charger in and it's charging the bike fine and dandy. I go to put my bike lights on while the bike is charging and I can feel a weird...

370 cycles is one years worth of riding for me haha! A 14s 32ah multistar pack will cost me £400 at a minimum, I don't know if I can justify replacing the pack every year :(

Hi all, My setup consists 14S2P Multistar Lipo 16ah giving me 51.8V 32AH nominal. My controller's maximum current is 40A and at this level there's normally a voltage sag of around 3V. Today I noticed while going up a long hill that the voltage sag was much worse than usual and that the cells...
