So I have a Tern Verge D9 that has 451 wheels. The actual size of the tyre on the bike says 37-451 Now looking for replacement tyres, it's actually proving impossible to find a decent make in that exact size. I can find other 451 tyres (e.g 28-451 or 25-451). Will these fit? Is the first number...

So I have a Tern Verge D9 that I've put a BBSHD on. Currently I have a 52T chainring on the front. The smallest rear cog is 11T but currently the bike gets max speed in a higher rear cog. Would I get any increase in max speed by going for a smaller front chain ring (say 44T or 46T) and utilising...

on my mid drive ebike the rear gear cog turns a little bit before it 'locks' and starts turning the rear wheel meaning I get a little 'clunk' when the motor engages. Is this normal or is something broken/breaking? (see video)

Had a BBS02 installed on my bike for a few weeks now but today got the chance to test out a BBSHD so swapped over. It all works well except that when under full throttle the watts meter on the display (500c) drops from showing about 1200w to virtually nothing. The motor is still putting out...

Bought this battery about 4 weeks ago but it's bigger than I need and I'm looking to sell it and get a smaller one. It was £395 new - I'm after £330 for it if anyone is interested. it's got a bluetooth BMS so you can see the state of charge etc on a phone app. Nice bit of kit. I'm located in...

So I have a BBS02 750w. Got the programming cable to look at the settings and it came set to 22amps max current. Just wondering what others are running? Some people seem to go 25amps and some stick to 18 or 20 I'm on 52v. Great performance so far. Just wondering if going to 25 would make any...

So I finished building a folding bike with a BBS02 750w motor and 52v 14.5Ah battery My use case requires me to have a bike that folds but I still wanted something with some power. After seeing the Lunacycles folding bike yet sadly not able to get one in the UK I decided to try and build one...

So I'm converting a Tern folding bike to an e-bike by adding a BBS02 my typical need will be 2 3 or 4 mile trips a day but that would be mostly throttle, some hills nothing outrageous Will a 10ah battery (52v) give me enough range? Or should I go for 14.5ah? I'm trying to keep weight down...

Looking at getting one of these motors but: don't want to wait more than a few days want either no battery or a small (10ah 48v) one want a 52T chainring want a decent colour display don't want to pay silly money (like more that about £420) Ebay doesn't seem to have 52T rings with the ones I...

can the BBS02 be used with a 52v battery or does it have to be 48v??

When using the throttle on these do the pedals stay locked and spin or is there a clutch so you can use the throttle and freewheel?

anyone have a BBS02 motor? if so does the throttle behave in a progressive way or is it more of an on/off kind of thing?
