I‘ve not left the battery to charge for an extended period. Of the 20 batteries in the pack - 18 read 4.0v and two read 4.1v. If I measure volts across +ve and -ve I get 40.4v

I have a question regarding my ebike set up: I have a home made li-ion battery 36v 6.8a with bms (10s2p). It is charging to 40.4v I have an S-06S controller and Q100 motor. when I turn on the system usung the thumb switch from the lcd 3, nothing happens. When I disconnect and reconnect the...

All sorted. I popped the motor open and took the clutch apart. Reinstalled everything and the wheel spins fine, both ways. All hooked up and working. Thanks for the replies.

Good point! It’s fine forwards. Doesn’t spin at all backwards.

Thanks for the responses. When I was truing the wheel, I noticed very little resistance spinning it either way. Now, it spins freely around the axle when turned forwards, and is super stiff going backwards, to the point I need a 10mm spanner to hold the axle whilst turning the wheel...

Update: I think you might be right regarding the disc bolts. Everything was turning freely until I installed the disc. So, with the disc bolts removed, I can turn the axle both ways. However, turning it one way has more resistance and it feels like cogs are engaging. When I take the three...

They are.... I can turn the motor on the axle one way and it goes around three-quarters of a turn before locking up. I can then turn the axle backwards for three-quarters of a turn before locks up and it feels like I am turning against a ratchet or gear whilst I turn it backwards. I have...

So, I spent the morning lacing my q100c cst hub into a rim. No problems. However, when I put the wheel into the bike frame, it has seized up and won’t move forward or backward. At first I thought that the disc brake caliper needed adjustment... No, all good there, with plenty of clearance...

So, I finally got my integrated PAS to fit - slightly wider bottom bracket required and, because tightening the crank arm onto the original bb had squashed the innards out of round, the PAS required a bit of dissection and fettling. It,s all back together and everything works. I think I prefer...

Out of interest, what is the appropriate C2 setting for the q100 and S06?

I did change the Throttle Start-up setting to 7 (standard) and all is fine now. I will have a play around with some of the other settings later this week to see what happens.

Thanks for the response. I think your suggestion is spot on, for the 2-piece PAS, i.e. the separate cable with fitting ring and magnet, coupled with the disc, that can be oriented in the various positions you suggest. My PAS is the ‘one-piece’ unit, with the ‘disc’ revolving within a housing...

So, after all the great advice given on this website, I have finally managed to put my bike together and take it for a ride. All is great and working well. One question I have concerns the PAS option. I have the integrated unit, KT-V12L which I have installed on the left crank (I also have the...

Thanks for the feedback. I thought I would provide an update of how things are going with my first installation. I bought a 36v 10.4a bottle battery to complete the kit referenced above. Installation was fairly painless - using disc brakes meant that I needed a selection of axle shims to get...

Thanks. All sorted now. Just waiting for the post......

Hello, Ready to buy my first kit..... I will source all bar the battery from BMS: Q100C cst rear motor (I am happy to make up my own wheel) Dual hall 12 pole pas S-KU93 controller S-LCD3 screen Thumb throttle The battery, I think I will get from a UK supplier - 36v 11.8a or perhaps a 48v...

long-time lurker, but now on the verge of building my own hub motor hybrid. I have a question regarding braking.... If my bike has hydraulic brakes, what are my options? I am looking to be able to control when the motor switches off either by stopping pedalling, or by throttle control...
