This is my second build. The first being the Trek 3500d. This time it is a Kona Kikapoo full suspension. Calibike motor and battery. 48v 20 ah this motor tests out to about 1800w. Rock Shox front and rear, Deore derailleurs, SRAM fluid hydrolic brakes. This time I put the controller in the seat bag. Speed: This controller is different than the first one. The Trek goes 18mph-28mph-39mph. This Kona goes 23mph-28mph-34mph A little faster in 1st, a little slower in 3rd.
