    Ebike battery fire

    Help me out with this one Neal, which of the many wires in a battery pack are we talking about? If it were one of the balancing wires shorting out, surely the wire which is thin, would blow out like a fuse in very short order before any further damage would occur? Ditto for any of the other...

    Ebike battery fire

    Another ebike/battery fire report to scare the pants off the ill-informed. When there are fires from well made, quality batteries that have been kept charged with quality chargers and not abused in the many ways that people do, then I'll worry, but in the meantime I'll be attributing such...

    Ebike battery fire

    A badly made battery what ever it is contained in is not a good thing but of course a bag battery is more prone to having problems if not we'll built. But with the right build quality and bag then a bag battery is going to be OK in my book. I wonder what @Woosh might have to say on this...

    Swytch Kit - no communication, nobody cares

    I wonder if the case study is with the knowledge/permission/blessing of Swytch?

    Help! Battery problems

    Oh dear, that battery looks to be as said already, something cheap and nasty from somewhere like Ali Express I would hazard a guess that the previous owner just bought it to be able to sell the bike in working order. But glad to hear that you are enjoying the ebike experience but to continue to...

    Battery problem

    As a basic principle, to replace a BMS requires a bit of a strip down to get to the module and then some unsoldering of some cables and usually just unplugging the battery sensing wires. One would have thought that for the supplier to do this would take an hour's work? The BMS it's self may...

    Battery problem

    I'm suspecting a BMS problem for several reasons: In first post you said battery had died but showing plenty of charge. I'm guessing you mean the motor assist stopped rather than the battery died? Then the charger led staying green. It normally goes green (from red) to show charging is...

    Review Tong Sheng TSDZ2 Owner Survey

    Enjoy the fettling - it's good to get inside these motors occasionly to check for any water ingress or re-greasing. If for no other reason it is good to explore the motor's layout to get to understand the various parts and their location and to realise that it isn't complicated to swap out most...

    Help! TSDZ2 clunk when free wheeling

    @Woosh makes a very good point as when you're free-wheeling nothing inside the motor is moving. Out of interest, when you took the Marin 'out of retirement', did you test ride it before fitting the TSDZ2?

    Tsdz2 Q-Factor and ankle pain

    Good to hear that things are on the up and that the 'Q' factor element has been put into perspective. I've always been sceptical about ordinary cyclists saying their bike's Q factor is an issue. For a normal healthy person it really is difficult to imagine that a few millimetres here or there...

    TongSheng Tsdz screeching noise.

    Bike noises like that can be a devil to find On my TSDZ2 I had what seemed like a sprag clutch failure in that on hard peddling the cranks would slip/skip a few teeth in the motor - a classic sprag clutch issue There's a YT vid somewhere with a guy stomping on the pedals to demonstrate this and...

    Why would you not wear a Cape in the rain?(current equivalent "Poncho")

    The cape I have (but haven't used for years) was a total blessing on some very wet days on a cycle tour - it has a hood too and underneath the cape all was warm and cosy. Downsides are as mentioned, the wind and exspecially a crosswind, see you being buffeted around a bit and of course a...

    TongSheng Tsdz screeching noise.

    I think (and understand why) you are clutching at straws here. In that audio clip: how near to the noise source was the recording microphone (just trying to understand the depth/volume of the creaking noise)? From a mechanical point of view I've never heard of a Blue Gear bearing failure before...

    Tongsheng tsdz2 48v issues

    I've no particular idea behind the problem but given that fitting a new controller inside the motor isn't a straight forward task and that the fault symptoms now are different to the original one, it seems less likely that the new controller is faulty but more likely a fault has been introduced...

    Calibre Bossnut with Tongsheng TSDZ2

    That @Paultig is a very neat conversion. On the battery support matter, rather than straps, have you considered adding rivnuts to the frame? Obviously an ordinary drill won't be able to line up with the underside of the frame but maybe a small right-angle adapter will do it? I bought one of...

    TongSheng Tsdz screeching noise.

    Assuiming there's nothin else wrong with the drive train I think a strip-down is inevitable On the non-drive side take of the crank arm and then the motor cover to reveal the main gear wheel. This area can be prone to water ingress and it's possible that there was minor corrosion going on...

    Raining on me ebike parade TSDZ2

    Yup, I had that problem with a friend's bike (LINK) - I said I could probably get it back to working order but being an impatient sort he just bought another and gave me his old one which I've stripped down and am in the process of re-building. I love how easy these motors are to strip down and...

    "Get me Home" Battery

    Bravo @vidtek for sticking with cycling despite having to put up with the discomfort. How's the TSDZ2 going BTW?

    "Get me Home" Battery

    Ouch - there's nothing worse than a sore butt from cycling - I'm guessing you've tried different saddles although that can be an expensive experiment. I've always got on well with Brookes leather jobbies - torture for some but heaven for others. Posteriors and saddles are very personal things...

    "Get me Home" Battery

    Yes, I do - I run my TSDZ2 250w mostly on ECO assist, so low current draw and as a 'reserve tank' I built a 10s 2p battery using the LG 21700 M50LT costing about £100 or less and I carry it in a small handlebar bag. This gives me around 8.5Ah+ and an extra 40+ miles I am now looking to build...
