First ebike build for me. Criticism welcomed.
Main Goals & Constraints I wanted to adhere to:
- Dual suspension (comfortable ride)
- Moto styled seat (more comfortable than bike saddle)
- Keep frame in original condition (no frame modifications)
- Suit urban riding and mild off-road/trail riding
- Must be relatively cheap build for an e-bike
- Spend under $1000 AUD ($700 USD) on electrics (motor/controller/battery)
- More than 750W
- Decent range eg. 50km+ (31miles+)
- Min speed 35km/h (22mph)
- Twist Thottle controlled (I am used to riding dirt bikes)
Final Specs:
- Donor bike - 2010 Specialized Bighit FSR I, 26" wheels, second-hand, very good cond. $800 AUD ($536 USD)
- Hub Motor - 1000W Voilamart Hub + 26" wheel + 26Amp Controller, SW900 Display, $360 AUD ($240 USD)
- Battery - 52V, 19.2Ah, 998Wh, 40Amp, UPP Hailong Battery, Panasonic 27100 cells, $510 AUD ($340 USD) October2023
- Max Power Delivery - At full charge ~1400W
- Max Speed - Flat ground, no wind 49km/h (30.5mph)
- Max range at full power, no peddling, 50km+ (31miles+)
- Max range at low power, no peddling, 60km+ (43miles+)
- Final weight 32kg (70.5lbs)
