Hello here is my little storry of my build:
It all started on that I wanted to make a fast electric bike, but I could not find a suitable frame where I could properly put ~ 1kwh battery, controller and a powerful charger. So, I started to design my own frame. For frame material I chose stainless steel because it was easy to get the right profiles. There are some pictures of building:
some sketches:
used parts:
- Clyte 3540 hub, with added hall sensors, 2x thicker phase wires and additional varnish layer on windings;
- Lyen 6fet pcb with little SMD fets that package can withstand 240A;
- 32pcs Headway 10ah cells 16s2p with standard BMS (this BMS is just for test)
- integrated 1.2kw ac/dc power supply for charging.
- all bike parts will be from DH bike.
and building begun:
finished welding:
and finaly I assemble all bike for first test, results are exactly I planed:
weight ~40kg;
top speed 60km/h;
acceleration is very good (it's impossible to keep front wheel on ground in first meters on full throttle).
sorry, but in pictures bike parts are not all right for this bike, in a week or two I must get all "right" DH bike parts and make some more photos:
I'm planing to make more frames for my friends, so if anyone would like a frame, please write, I'll put new topic on sale section.
