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...

I have checked gov.uk pages and if I’m looking at the correct code (commodity code 8501200030) the duty for ebike motor kits is 2.7% (same for batteries) which works out to be around £22 on £800 purchase. So it seems like you have been charged (somewhat) correctly. But that's just duty paid...

Thanks, does anyone know how much tax and duty is charged for ebike kits and batteries? Are we talking 10%, 20%? With that in mind their competitive pricing does not seem be that competitive anymore... plus I recon if a defect product is sent, even if Paul sends a free replacement I’d have to...

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...

That's right, I was looking to upgrade to 42T or even 36T for nice acceleration, top speed is not really something I'd be pursuing... What about reliability of BBS02B vs BBSHD? Actually, what's the difference between standard BBS02 and B-version upgrade?

Thanks tommie, what about efficiency and acceleration?

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...

Thanks flecc, I suppose it's worth spending few extra quid for years of reliability!

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...

Depends what you mean by stupidly high power? My original post mentioned 1500W DD hub motor, I guess for that torque arms are a must?

So the question is, is single torque arm enough or should you install one on each side of the wheel?

Thanks, so it shouldnt be a problem then if a quality chain is used and optimal tension is maintained? Do you recommend any source for instructions how to limit start current? I’m looking to buy BBS02 with LCD KT3

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...

Thanks Woosh - that's indeed a very good reason to install a torque arm.

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...

Hi everyone, As in the subject line, do you think torque arms are required for conversion kits up to 1500W if DD hub motor is mounted on the rear wheel? I have read a lot of stories where front forks snapped under much stress but did not find much evidence to suggest rear frame bars can't...
