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...

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 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...

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...

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. £12 a pair and free postage within UK...

As in the subject line, I'm looking for ways to increase the initial acceleration without touching the motor, controller or battery. Not interested in top speed, just bigger 'oomph' when launching at traffic lights. Currently using BBSHD on a 29er bike on 2.3 tyres with 42T lekkie and 28T low...

As in the subject line, recently my BBSHD started to make grinding noises when starting up, the chain ring does not spin for about a second or two but then it feels like it ‘gets in the gear’ and is back to normal again. This seems to be an internal issue, nothing seems wrong with bike’s...

Hi all, I have a new battery and charger having done only about 5 charging cycles. I noticed last night the charger makes a high pitch noise when the battery is being charged. I noticed this when battery was almost full, but perhaps the noise was there before and I just wasnt there to pick it up...

This might be a dummy question but does BBSxx require a freewheel or a cassette is fine? I’m planning on upgrading my stock 14-28T to 11-34T for larger range of gears. Thanks.

Benefits of upgrading the stock ring to lekkie are extensively covered on this forum and I will be upgrading to lekkie at some point for sure, but given a tight budget do you think I need to get BBSHD with lekkie ring immediately or can it wait a few weeks until I save up the extra? I read some...

Sanyo NCR cells seem to be a step up from Samsung 29E with more capacity per cell, but is there any real advantage of buying a battery based on NCR over 29E apart from less weight? I assume reliability (less cells = less things to go wrong), anything else? Performance/power output improvements...

Does anyone have any experience with purchasing stuff from em3ev.com website? They seem to have very competitive prices on BBSHD and 52V batteries and although website mentions 'local support in UK', the only contact option is a form on the website, and that seems a bit dodgy. At first glance...

Your thoughts on gear shift sensors, are they strongly recommended or an optional gimmick?

As I will be riding predominantly on flats and very light hills in an urban area, is it worth buying BBSHD over BBS02B? Would that extra £200 make any difference whatsoever? I don't think all that extra power of BBSHD would ever be needed, and from what I read BBS02B seems to be as reliable as...

As in the subject line, at first glance cyclone mid drive kits seem to be quite similar to Bafang kits and yet they are half the price, what are the differences in performance, reliability etc. as it seems like cyclone is not that popular among fellow enthusiasts?

Hi everyone, as in the subject line - I was wondering what's the difference in battery usage between mid drive motor (say BBSHD / BBS02) and a hub motor of the same power. Let's assume 10 mile ride, mostly flat, PAS set to max level and identical riding conditions. Does anyone have an...

I recently came across this video where the owner of a bike fitted with a standard (not modded) BBS02 complained about chain snapping pretty much every 2-4 weeks if the bike was ridden with throttle only. Mid drive motor would definitely wear out the drivetrain considerably quicker than a human...

Hi everyone, As in the subject line, it seems a lot of manufacturers selling 700C conversion kits also advertise them to be suitable for 29er wheels, as both sizes are 29inch wheels it would make sense, although rims for 29er are typically wider. Has anyone used 700C conversion kit on 29er...
