Just been out for an hour on the V20 software and a few things to report.
There's a fraction of a second longer motor delay once stopping pedaling than the standard. Its noticeable but not an issue to the point I'm not sure I would spend time trying to sort the code.
I think the cadence top end problem is slightly worse over the standard 36volt motor run at 48 volts. I will experiment with the numbers in the advanced menu when I get a chance. I normally ride a non electric mtb so do run a higher cadence than most.
Ummm really really struggling getting my head around the way you can change the display outside of the configuration menu which seems to work well. The press the on/off button with a short and long press of the up button is so temperamental as to timing that I was getting into all sorts of unintended fields that in the end I gave up for the night. I'll have another go tonight as I can see the method but my fat fingers and age
is just not getting the desired results.
In the default power settings its way to easy to get 550 motor watts off even the 3rd level, I know one can change it but perhaps the default could be backed off a bit.
Emtb, I'm not sure yet as I had it set too sensitive and by consequence could pull the 550W upper level I had set in the upper limit, far to often.
The motor is definitely quieter and if it wasn't for the small clicking sound of a partially stripped blue gear then we are probably quieter than some of the commercial Ebikes out there. Not quite Bafang but probably better than the early Bosch and Shimano units I have ridden.
Mind you had a real hoot and a big grin so I can't complain too much, all in all pretty cool guys and big thanks to you developers as in total, way way better than the factory TSDZ2 units.
