    TSDZ2 front mech, adapters needed

I had this working before, but at some point I lost the mech. I want to use a direct mount/braze on front mech, and an adapter (my bike is only designed for...

    Tongsheng TSDZ2 - unavailable on AliExpress?

    I bought a Tongsheng TSDZ2 last year on AliExpress. There were loads of them - 250W, 750W, 36v, 48v, 52v... I need to buy another one, but I can't see any of them on AliExpress. There are a lot fewer on ebay, too. Why? Has it gone out of production or something?

    Tongsheng, add throttle functionality

    I use my Tongsheng as pedal assist only. I would like to add a throttle to it. I have a throttle lever, but the plug on the cable is the wrong shape to connect to the motor unit. AFAIK the Tongsheng comes in two versions, with & without throttle. I seem to have the version without. Is it...

    tsdz2, no power to motor

    There is no power to the motor on my tsdz2. I can turn it on and the screen (VLCD5) lights up. However, when I turn the pedals there is no power. It has worked before, but not today after I transplanted the kit from my upright to my recumbent. I have re-read the manual and I am satisfied it...

    p850c compatibility, flexible open source software

    I'm aiming to install the Flexible Open Source firmware from casainho. I recently obtained a P850c controller. Will they be compatible? (The answer is probably listed somewhere, but I'm a bit of a noob and very baffled. Trying to keep it simple.)

    TSDZ2, can I use an aftermarket charger?

    I recently installed a TSDZ2. It came with a fan cooled charger, which I don't like. It's bulky and shouldn't need moving parts at that power. I don't expect it to last. Can I use an aftermarket charger? Or, could this cause problems with overcharging? If it's a smart battery with a dumb...

    TSDZ2, how do I know I'm not wearing out the motor?

    I recently installed a 52v 750w TSDZ2 motor on my road bike. I know that riding in too high a gear will eventually wear the motor out. However, how do I know this is happening? In other vehicles, you can tell if it is overworked. You can hear a car's engine struggling, or automatic...
