There is a member here, DarkAngel who has modified Curry bikes for more power and speed. Depending on your size and weight you may simply need more power. The Currie brushed motors that you show are quite powerful with their internal gear system. Interesting about mid-mounts as I had not seen that particular kit before. Usually the noise level would turn me off but I understand the newer My16 and My18z motors are quiter. The Lithium battery that you show is not a great one for power or longevity.
