Has anyone tried the silent PEEK nylon gear replacement from Luna? I am looking to replace the stock nylon gear with something more robust as I tend to ride on throttle quite a bit. A steel gear seems to be the toughest option but is REALY noisy, so the PEEK gear could potentially be the sweat...

Just ordered molly grease, will be greasing it up next weekend ;) I suspect it may be something else though, as it started quite suddenly rather than building up over time. First squeaks heard after steep hill climb - could it be a worn out clutch? I did have an issue with grinding gears in...

My BBSHD developed a loud squeaking noise when running at heavy load, very similar to what's shown on this video (see 30sec mark): It's quite loud but only audible at heavy load, i.e. either when riding on throttle or pressing pedals hard (also without PAS). When I get off my bike and move...

I checked the display manual and it says the setting allow you to change auto-off between 1min to 9min. The issue I have is motor immedially cuts off once error 21 pops up - which is typically about 3 seconds into the ride. Have you had the same issue, or did your motor keep going despite the...

How do you turn auto power off?

Thanks. Is there a way to keep the motor running until I fix it? From what I read the error 21H usually allows the motor to keep running, but in my case it stops and stays unresponsive until switched off & on again.

I just had the same issue today. I managed to pinch the cable connecting the speed sensor to the controller while installing new bike stand :rolleyes:. The damage is about 6 inches away from the controller, so it’s at about 1/5th of the length of the cable. The controller shows 21H error about...

I recently upgraded front fork to rockshox recon so I can swap the front disc brake from 160mm to 203mm on my 29er. Since then, under braking the wheel pulls heavily to the left, so much that it rubs the forks. Interestingly, the wheel does not align back when braking is over, but when I take it...

His name is David, slightly older guy, seemed very nice. Turned out the button would get stuck due to improper alignment (factory issue), it was fixed quickly and free of charge (under warranty). It still gets stuck every now and then, but is workable. David suggested to replace the button...

Thanks. I got an email from Joseph at em3ev earlier today and was offered new switch or inspection by their technical consultant locally in London. Went for option two, so I trust they will be able to fix it.

hard case

Have you done a proper gear adjustment after replacing the ring, if not then you should start with that. Make sure the limits are set correctly (both front and rear gears). Also check if you're using the correct chain size for your setup. The problem could also be a change in the chain tension...

Hi all, as in the subject line I recently started having issues with the power switch button on my 52V triangle battery from em3ev. The battery itself works fine, but the power button is playing up and I cannot switch the battery on or off. LEDs seem to be a bit dimmed too, not sure if that's...

I read that Bird, the e-scooter sharing company announced adding shared ebikes to their fleet. They will soon be coming to multiple cities across the world, including London and few EU capitals. Unlike Jump or Lime, they will be fitted with 52V batteries and 20amp controllers. The press release...

For sale a brand new pair of hydraulic brake sensors for Bafang BBSxx. Will work with all types of brakes, hydraulic or mechanical. I purchased them for my BBSHD conversion kit but didn't really like the way they operate and decided not to install them. The kit includes sensors, magnets and some...

Update on the old thread, as someone could experience similar issue in the future. Athough there was some good advise in this thread, in the end I haven't taken any action and let the bike sit outside under a bike cover for another 2-3 weeks whilst weather was improving and temperatures went up...

If you meet such officer he would probably stop you just to complement your bike and give you high five ;) I would imagine if the crackdown was ever to be launched it would start with electric scooters which are all and without exception illegal, very easy to spot and way more popular on...

Unless an officer is an ebike enthusiast they will never spot if the motor is overpowered or not. Event then, unless there is a label on it that says it's more than 250W, or there is no label at all (as required by the law), you could claim this is a 250W kit. Similarly with mid-drive motors, it...
