Interesting, obviously we’ve all been using the same universal throttle on Bafang and Tong Shen for years, many options to change.It doesn't void the warranty. No you cannot use the bafang throttle please do not attach it.
We have 2 throttle options. We can ship you one no problem
Your basic one looks like same old, is pinout different ?
only 3 wires, shouldn’t be hard to get it to normal standard
Your upspec one looks trick, aesthetic joy or better (smoother) action ?
It would be good to read of someone actually using and testing a toseven hard, ie giving it 52v , some amps and steep climbs, any links .?
I need tech detail not fancy youtubes vids that tell you nothing
