    Tongsheng TSDZ2 Build - This much I know - Part 5 - Cabling/ electrics

    Another great writeup @PGT - I'd considered Wago connectors before whereas the 'traditional' connectors are ofeten XT30, XT60, Anderson etc. The Wago 221 in-line splicing connecors (which it looks like you are using?) are rated for 32A so no problem for the TSDZ2. Obviously not waterproof in...

    Tongsheng TSDZ2 Build - This much I know - Part 2 - Donor Bike

    A great write-up @PGT - the frame type with the down tube like in your last pic are potentially problematic - of my four TSDZ2 builds the most awkward one was of that type - I ended up carefully grinding enough away to make the motor fit but that might not be for the feint hearted on their new...

    Tongsheng TSDZ2 Build - This much I know - Part 1 - General

    Hi @PGT - I'm just starting to read through your various posting on the TSDZ2 build and I think it is really good for someone to take the time and trouble to write down their experiences as it will inform others as whether to do their own conversion or not. You're absolutely right about kit...

    Experiences with Open Source Firmware on the Tongsheng TSDZ2

    Thanks for that. Correct me if I'm wrong but isn't 1c.4 for the 860c display? I'm using the vlcd6 so it looks as though 1c.2 is the latest for the vlcd5, vlcd6, xh18. (BTW, the fixes listed for 1c.4 are very similar to 1c.2 to no doubt to get the firmware for both display sets to a comparable...

    Experiences with Open Source Firmware on the Tongsheng TSDZ2

    Topic creep - I thought this thread was about Open Source Firmware? So whilst on that topic, I have been using V20.1c.1 (I have the VLCD6 display) for some time now although I know that there is a v20.1c.2 too - is that the latest release and has 1c.2 been running for a while without issues?

    What is the radius (or diameter) of the 44t Tongsheng TSDZ2 chainring and how far out does it extend from the edge of the bottom bracket?

    I see what you're saying but I think the OP is concerned about the chainring teeth touching the chainstay and at that point the chain isn't of course on the chainring :cool:. And I'm about to correct my post as the chainring I measured is 42T not 44T - durgh - so your other post giving 184.6m...

    What is the radius (or diameter) of the 44t Tongsheng TSDZ2 chainring and how far out does it extend from the edge of the bottom bracket?

    I have a spare EDIT 44T chainring and I've just measured it and it is 175mm diameter. My mistake, I measured a 42T chainring - durgh. As @Woosh says in another post, go for 184.6mm for a 44T chainring. The motor casing covers the edge of the bottom bracket so I can't measure precisely, but I...

    What is the actual measured distance between the bottom bracket and the Tongsheng TSDZ2.

    I have fitted four TSDZ2 and although I can't give you an actual measurement, I can tell you that in all cases I have had to remove the cable guide. For the single gear cable to the rear deraileur I managed to run a short length (20cm ish) of gear cable outer between the BB and motor, secured...

    saddle catching trouser pocket

    I get the same/similar problem when riding our tandem and solo bikes, especially so if wearing lycra pants which because of their softness, tend to catch on the saddle nose more so that ordinary cotton material what I do is to make sure my butt is a little further forward on 'take off'...

    TSDZ2 "Brake Error"

    I suspect that for what ever reason, the micro controller itself can become firmware corrupt or electronically fail and simply stops working. I have no proof that this is the case but my installation just stopped working after around 2,700km and shortly after I'd loaded v20.1c.2 for my vlcd6...

    TSDZ2 speed sensor works partly

    Just tidying up this post in that the OP's issue is still resolved as at 18Jul22 as mentioned in this post HERE.

    TSDZ2 250w VLCD5 speed sensor strange behavior

    Just to clarify when you say you have the exact same issue - are you saying that you initially installed the TSDZ2 with the VLCD5 display and the ebrakes and all worked correctly until you then added lights and a new yellow splitter cable and speed sensor? And if you did add lights etc, can you...

    My Cargo bike build.

    Hi @Nealh - a question please: looking back at your post #425 where you fitted extra bearings to the drive and non-drive side of the main gear shaft/axle: I've now obtained some bearings and 'penny washer' seals and am all poised to go but on the non-drive side (and looking at your picture)...

    Tongsheng TSDZ2 review and build tips.

    @OrdnanceAnt - you may also find that the bottom part of the down tube where the cables exit, fouls the motor too? This was the case with my friend's bike that I converted for him - basically I ground the offending metalwork back until the motor fitted It was a brand new bike so I didn't have...

    Refurb/rebuild

    I bought a rack mounted battery but no matching rack but fitted it very nicely to the bike's exiting rack using rubber lined 'P' clips screwed into the battery case fitting points. Whether that is possible for everyone depends on having suitably located rack attachment point too, but maybe worth...

    You get what you pay for!!

    Hah, The term 'bicycle like object' comes to mind! Your experience proves that despite appearances, you really do have to test ride a bike before purchase. Having said that, the law of diminishing returns plays a part here too as in is a £3,000 bike twice as good as a £1,500 one or just an...

    My Cargo bike build.

    Excuss my ignorance Neal, but I've not heard of neoprene face seals - what are they - just neoprene washers the same diameter of the bearing? Any web links or pics of these items please? Ali Express do the 6902 2RS at very reasonable prices.

    Where can I get a compatible replacement handlebar display for a Pendleton Somerby ebike? (King Meter 790 LED)

    Good Grief - whilst sorting out the bike shed today, I have actually found my old 790 display from my old Pendleton - if it's of any use to anyone, drop me a PM - just pay for the postage and it's yours. I've also got the original Pendleton controller as well if you want it?

    Tongsheng TSDZ2 review and build tips.

    On my bike fit I needed to remove the bottom bracket plastic cable guide - rather than re-route the rear derailleur cable, I used a short length of gear cable outer sleeve (maybe 200mm long) threaded through the small gap where the cable guide was and secured each end of it with cable ties. This...
