after finding the PAS (pedal assist sensor) connector, i connected a push switch and now the motor is running on full speed when i push it.
it is not perfect, but can run the e bikes at uphills and go nice in flat roads.
the controller it programed to run at 25km/h max.
for long run rides i connected on/off switch and now i can comfortably seat and go for long distances.
this 250w motor is powerful when it gets the right amperage it needs.
if you like to support, you can order from me this controller. it’s a good quality
you can also find the wiring diagram in the product page
