hi,
i am very new to this ebike field, due to my own interest i started to thinking about ebikes and planned to create controller from scratch.
How the interest came ?
I am from India and always i try the new technologies, just like that TVS (one of motorbike company in india) announced about launching "TVS Qube", but more than 3 years, they not launched it.
TVS Qube is a hybrid 2 wheeler (scooter) which work on petrol as well as electricity stored in battery, i dreamed it to buy one, but that delay caused me to think "whyn't you can develop one ..??" then i started searching in internet about hybrid and electric ebikes, this way i concentrated more on eBikes in my free time.
After a small research, i planned to build eBike (bicycle with electric powered one wheel), that is we have to replace rear wheel by hub motor fitted wheel.
Parts needed for Ebike :
i thought, we can buy this and assemble it, finish, but here the problem start, we can buy everything, except controller, because all the controller available here are only for 250W BLDC motor, but i planned to create for 2000W, so if i got the controller means, Project finished, but controller...????
thats why i created this blog about creating controller from scratch, i planned to use my free time for creating the controller circuit.

Parts needed for Ebike :
- One Cycle (mountain ranger or one with good front/back suspension is needed)
- 48V 2000W BLDC Hub Motor (with sensor)
- Rear rim with high gauge spokes (we have to Lace the hub motor in it) and Tyre.
- Lipo Battery (2 nos)
- BMS (Battery management system) so we can charge battery
- Throttle (to control the present speed like we do in bikes)
- On/Off Switch
- Cycle analyst (that display speed/battery current/temeperature and all)
- Controller.
