- Review and thoughts on my hardtail MTB after converting to a mid-drive eMTB using the Tongsheng TSDZ2 with Open Source Firmware. Bike has about 500 miles on it since conversion with mixed use of off-road (MTB trails), greenways (paved or hard pack gravel), and chip&seal /blacktop backroads. At time of recording I also have over 700 miles on my full suspension Giant Trance X E+ 2 Pro 29r to compare against.
Notice at the very start of this video with the motor screaming, the MTB tires are still installed.
can you get rid of the top speed limit?
Yes but as mentioned the gearing is more of a limit. Even with a rear 11t cog. Putting on a much bigger front sprocket would make it struggle up hills.
@@MTBPerspective Imagine using the stock firmware and running into the cadence limit of 90 instead of 120 with OSF
Fastest I been able to ride with stock sprocket and a11t on the back is around 30mph on a full charge.
Is this the 500W version? How would you rate the strength of the motor?
48v kit running the open source firmware so it can be set at various wattages. I've got mine set to go no more than 380watts so it stays cool- plenty of power even at that.
@@MTBPerspective Did you install the cooling kit or not?
@@MarvinWestmaas no cooling kit
@@MTBPerspectiveOk, I wonder why? It's cheap and works wonders allowing utilizing a lot more power.
Though that might be why you didn't do it, this way you feel you're still 'pushing yourself' to do the max effort you can?
You didn't say which power of motor you had, which was it, 250, 350 or 500W?
This is exactly it:

@@MTBPerspectiveThis link is to the version B. I understood the one in the video is the previous version, correct? Btw, I have exactly the same kit and was looking for a review of it. I agree it is not for real mountain biking, but it is fun and good enough for less demanding trails /roads. Thanks!
I got mine mid 2022 so they likely have updated to the B version. As mentioned towards the end of the video it is a great kit for non-mtb riding but if Id did it again I'd skip the open source and just use the standard kit and matching battery voltage for any of the tongsheng kits. Gets old fast taking them apart to replace burned out motors and controllers.@@cilami
@@MTBPerspective I got 4000k on mine without any issue. Running OSF @ 750w, cooling kit mod and bearing mod done when installing OSF off course. If pushing more then 500w you need the cooling kit, and pushing more then 750w you need the temperature sensor.
Anybody want a programming cable for tsdz2/tsdz2b?
I would. How much?
me too, how much?
£30
Make one yourself, the cables which come with your ST-Link v2 will work fine. Break the black plastic connector housing, put heatshrink on the metal connectors, widen the connectors using a thick needle, and they will slide right over your pin connectors.
