Issue resolved. The STlink dongle needed a firmware update. Once updated it now connects ok and I've flashed the motor.

yes it shows 5v and Java is fully installed and working

I don’t have the bike here atm but I get the following output when the stlink is connected on Linux. The other Stlink I have outputs the same values but the serial number is just showing ‘Y’

I've tried both Linux and Windows 10 on 2 different PCs desktop and laptop. Java is working all ok. Assume it's a hardware issue or incompatibility with the motor.

Tbh I'm a bit reluctant to spend any more money on clones as 2 different ones from different sellers haven't worked. I could buy a genuine one e.g. from CPC farnell but there is no guarantee this will work either...

Update, tried with a much shortened cable (see attached pics) at 3.3 and 5v. No change. Any other suggestions before I give up? I've tried 2 STlink clones from different vendors and no joy.

I did try 3.3v instead of 5v and no difference. Been busy with work but will try the shortened cable this weekend. Does the OSF make much difference to the torque or top end speed (compared to stock firmware 48v 16a)?

I will try shortening the cable first. This is the second STlink dongle I've tried from Amazon (using different sellers) so it is more likely to be the length of the cable.

Yes software all installed correctly. It just refuses to connect

Hi all, Many thanks for all of the advice. The cable would not work with my old 36v motor or the new 48v motor. The entire cable is 13cm long from end to end. I have tried with windows 10 and 11 installed on a fairly modern laptop and a separate desktop PC. Also tried Linux and no joy with...

I have recently purchased a Tongsheng TSDZ2 48v 750w kit from PSWpower to replace my previous TSDZ2 36v 250w motor (also purchased from PSWpower). I have a VLCD5 and wanted to use the open source firmware on the unit (the embrusa firmware for the VLCD5 screen). I bought an ST link adaptor from...

Cheers both, I will check the chainline first before I order anything

Ok thanks guys. So in summary I need the following: California Ebike stabiliser bar Lekkie bling ring spacer 1 or 2 or more? Longer M6 bolts into the motor Loctite/thread lock I’ve attached pics, tell me if this is your thinking?

I don’t really fancy using the angle grinder on the frame as the bike is brand new. I have one of those California evoke brackets on my other bike, might buy me 1mm. I could grind a bit off the motor but still not sure if that is going to be enough. I’ve attached some more pics.u

Ok thanks Peter, I also found this but it isn’t cheap (still cheaper than buying a bbshd though) http://precialps.com/uk/accessories-bafang-bbs01-bbs02/12-kit-modification-bafang-bbs02-en-100mm-fat-bike.html

Thanks for the replies guys. I would rather reuse the existing motor rather than buy a brand-new BBSHD as these are the best part of £500. Would any of these ideas work? The second picture I stole from another website.

Hi, I’ve have a Bafang bbs01 kit I want to transfer to my new Cannondale mountain bike. Unfortunately,my chainstay is in the way & I don’t have enough threads showing to attach the lockring & mounting plate. I’ve got a lekkie bling ring. Would a spacer work? I’ve checked this thread out but...

Hi, I’m still on then lekkie bling ring, decided to put that on hold for now, may take the plunge this summer...

Thanks for the replies guys. A couple of questions: I assume the sturmey archer cassette hub would require a custom wheel? The double chainring solution looks quite good, I would need a front derailleur shifter added to the bike to make this work? I removed the original front derailleurs...

Thanks rilot, that sounds like an interesting solution. Does it just slot into the back wheel? I not a good DIY person so would not want to build a wheel for it.
