I have a Phoenix A3: 20" foldable ebike, which I imported from Tabao in China. It is the style with a hidden battery and 250w's. Unfortunately, it currently only has a max speed of 25kph (15mph) which is quite slow. I was wondering if anyone knows about how to remove the speed limiter to increase it to 32kph, or if this bike actually has a speed limiter? I tried several tricks with no success.
