Bafang BBS03/BBSHD programming

Has anybody had limited programming experience with the new Bafang BBS03

The BBS03 is more commonly referred to as the BBSHD so I've added that to your thread title

Thank you Anton .

I wrote up a few articles about it, geared more to what you'd want with a street application (i.e. high cadence, low-torque pedaling). I've recently done some work with urban riding in steep hills that I'm eye'ing for a separate update of some kind. In particular one of the things I've taken better advantage of is the soft starting of the motor under both pedal assist and throttle. Its not brain surgery but not something I should just toss out in a vacuum, as these settings tend to be somewhat interactive.

I recently came across this diagram that is now embedded in the latest version of the Bafang Config Tool. It came out in 2019 so 'latest' may not be quite the applicable term. In any event the graph gives a visual representation of how settings are supposed to work, as interpreted (educated guesswork) by the DIY community.

Ignore the actual settings on this snippet. All I did was open up the tool so I could screenshot the graph.

If you want to get hold of a reasonably easy-to-implement, portable motor interface, google the Speeed app (note the three e's) and put it on your Android phone. You then connect with a Bafang cable and a USB C adapter to your phone and you're in business.
