    Faulty BMS?

    I have a conversion kit fitted to my utility bike; it has a new Tongsheng motor and a 5 year old Hailong battery pack. All works well, except when I first set off, after between 5 and 10 seconds, the power cuts out for a moment. If I'm pedalling, the motor drops out and I have to turn it on...

    Are any mid-drive conversions waterproof - and does it matter?

    I am trying to decide what to buy to replace the dead GSM motor on my Raleigh Pioneer utility bike. I like the idea of the torque sensing on the Tongsheng TSZD2B, but I'm a bit concerned that it's only classed as water resistant to IP54, and the manufacturer advises that it shouldn't be used in...

    Help! Intermittent power on GSM mid drive

    That's helpful. I had a look inside the motor unit today, and there's no obviously sign of anything overheating, although most of the electronics are potted up so I can't get a good look. It's quite clear that there's no way of replacing the internal controller with a similar unit because of...

    Help! Intermittent power on GSM mid drive

    I did 15 miles on it a few days ago, in quite hilly terrain, so I suppose it’s possible that I’ve cooked the controller. Certainly didn’t get hot this morning - I only did a few hundred metres before I noticed the problem. Is it likely to be the controller, or the motor windings? If the...

    Help! Intermittent power on GSM mid drive

    Hi, all, I’ve been happily using a GSM 250W mid drive kit on my hub geared utility bike for the past 5+ years, but this morning it started to play up. It’s fine for 20 seconds or so, and then the assistance cuts out for 2 or 3 seconds before returning to normal and then the good/bad cycle...

    The importance of good connections!

    Err - that should have read "a Maplin station" Sent from my MI 5 using Tapatalk

    The importance of good connections!

    The size of the soldering iron bit is also important. I use a napkin 50w soldering station, with interchangeable bits. For meaty jobs I use a meaty bit (ooh err missus), and turn the temperature up. That way I get a quicker job, with less chance of overheating adjacent items. Sent from my MI 5...

    bike locks

    Most locks can be manipulated, but it takes skill. Most thefts are committed by scrotes that just in brute force and ingnorance. Sent from my MI 5 using Tapatalk

    bike locks

    I use one of those dutch-style frame locks, and I have a decent quality chain that's designed to plug into it. All made by Abus. It's not their top-rated one, but the next one down. But then my bike doesn't look anything special - it's a Raleigh utility bike with hub gears and a GSM crank drive...

    E-bike with motors greater than 250w, speeds above 15mph and the UK police

    That's good. I didn't realise that you were so well organised. Sent from my SGP311 using Tapatalk

    E-bike with motors greater than 250w, speeds above 15mph and the UK police

    It sounds almost as if you're advising a lobby group who are about to try and get the rules changed. Is there such a group in the UK that represents the interests of ebikers, or do our legislators just blindly adopt the EEC decisions?

    But that's only the limit for assistance. There's no limit if you're using leg power, and they'd have to prove that you weren't. Easy-ish if you're doing 30, but much harder at 20. Sent from my MI 5 using Tapatalk

    E-bike with motors greater than 250w, speeds above 15mph and the UK police

    In the days before my knees gave out, I remember seeing about 35 mph on the speedo of my dawes galaxy (not an ebike) on downhills. Dread to think what would have happened if I'd need to stop quickly, those Weinmann centre-pull brakes weren't particularly good. Sent from my SGP311 using Tapatalk

    E-bike with motors greater than 250w, speeds above 15mph and the UK police

    Although there are some private road with public access, for example royal parks, where the speed limit rules specifically include cycles, and since many of them are 20 mph, it's far from being only a theoretical issue. Sent from my SGP311 using Tapatalk

    You're about 95% right. This article is quite interesting: http://www.slatergordon.co.uk/media-centre/blog/2015/06/can-cyclists-break-the-speed-limit-or-does-the-law-only-apply-to-motorists/ Sent from my SGP311 using Tapatalk
