Thanks for your reply. Do you know which direction it should facing, A or B? I might be able to dremel it out and stick it on the outside of the pedal section. That way it still spins. The unit comes with a throttle also, so if all fails I could just use rely on that. If I opt for throttle...

Hi everyone, My ebike rear hub kit and battery finally arrived. I’m installing it on a BMX 24” cruiser. It’s not going to be an everyday bike or commuter, just an alternative weekend travel option when I catch up with friends. I’m having a bit of difficulty figuring out this PAS device. I’m...

Can anyone recommend a torque arm set that might work with a bmx? All the ones I’ve seen appear to require a second fixing that the bmx doesn’t have...

This is really helpful. Thank you.

Not sure. Don’t see any other option at the moment. I’ll play around with the kit to see if I can make room. I only need one sprocket, so maybe I can make it work with less movement.

I’ve looked at front hub, but haven’t heard great things. I might give a 135mm kit a shot, widen the rear dropouts 12.5mm each side. They aren’t super expensive on alibaba, so if it doesn’t work out, I’ll go a front hub. The sellers are recommending a 48v 13ah hailong battery. Any good? I need...

I’m thinking of manually widening the drop outs to 135 as per this YouTube video. I suppose this will mess with the chain alignment?

Hi guys, I decided to keep my Raleigh Twenty as is and work on my 24” bmx. I’ve looked at mid engine builds with the same bike; but it looks like a nightmare for chain alignment and quite a bit of grinding to make it fit. Decided I’d opt for a rear hub kit. The problem I’m having now is...

I’ve been doing a bit more research and I might opt for a rear hub kit. Only because I don’t trust the front forks and any failure upfront could be dangerous on London roads (or any roads!). Would this be an issue if the rear wheel is a slightly different size to the front? Also, any...

Sorry for the late reply. Any suggestions? I just rode the bike back from the office, worst day for it, but was the only time I was going to be near the office for the next couple of months. The brakes were terrible. Worse than I remember.

Sorry to bombard the thread, but would a mid mount motor (ie bafang 750/1000) work? The rear wheel has an internal 3 speed hub, so I’m thinking that would allow me to retain 3 gears to help move me along (6’3 115kg).

Not too sure how wide the front is, but this is an image I found from when I first bought it. Unfortunately the bike is still at the office. I’ll walk to the office this weekend and cycle home with it.

Hi, Would the smaller wheel not give it extra torque, therefore I’d be looking for higher rpm to gain top end? Maybe I’m misunderstanding something here. Amoto65 is right, the wheel size will be off. Do they sell kits that include a 20” rim? Maybe that would be more suitable...

Hi Woosh, More than happy for it to go in the Whiskey box, assuming it fits. I'd also be up for replacing the box if necessary. Would a front hub 20" kit be better than a crank positioned motor? Ideally trying to keep everything under £500. Cheers

Hi All, The current climate has me thinking about putting a motor on my little Twenty. See the photo link below. I suspect I'll be back at work in a couple of months (London) and want a bike for my daily commute. My flat to the office is approximately 3.5-4 miles each way, and it is quite flat...
