Hello,
This is my first post and hoping someone can steer me in the right direction. I live in Australia ,Gold Coast.
Just received Dengfu E22 frame and hope to modify original controller or purchase an external controller that will allow the Ultra to have increased RPM over standard. Not looking for huge power . Battery will probably be limited to 52V as the E22 has a small battery compartment. About 88mm wide by 80mm high and 375mm long. Length of compartment may be able to be increased to 400mm .
Single speed with around 1 : 1 ratio with top speed around 70 kmph . I weigh 70 kg .
Have never, built an ebike before ,modified a controller or built a battery .
Thanks for any help with achieving this.
