ebiker
10 mW
After reading this forum for months and collecting ideas over ideas I want to present my first build now.
Everything started when I first bought my 1000W 48V Goldenmotor kit from ebay. I took my old Mountainbike and tried to fit the parts to the frame. As battery I bought a 10Ah 48V lifepo4 battery from ebay. The problem was that is was too big to fit into the triangle of my frame. So I had to think of another solution for mounting the battery. As I definitevly didn't want to mount a rack to my bike, the only space to fit the battery was on thr top tube of the frame.
To make a first test ride and to protect the battery from any kind of water I decided to wrap the frame triangle into some plastic sheets.
First test runs showed a top speed of about 54 km/h. Which felt pretty good, but not as good as I wanted it to be
Moreover the look of the bike was still pretty worse. So the next step was to build a new canopy around the frame.
I disassembled the frame and cut some aluminum u-profiles which were fitted to the frame triangle. Then the sides were covered with 1mm aluminum sheets.
After painting and assembling the bike looked like this:
As I was still not satisfied with the power, I decided to take it to the next level. I bought a 72V 70A Infineon controller from keywin and some lipos from hobbycity. So with that setup pumping about 5000 W into the motor the next test ride showed about 63 km/h top speed and an impressive torque.

But this is definitevly not the end of the story. I will completely redo the frame (probably a different frame), install large disc brakes and maybe some time later try to get one of Methods 100A controllers (if he will sell them as complete units, not kits again )
