Hi, I am looking at building my first e-bike and I am seeking some advice for my build. Basically looking to build a fast dual suspension electric bike that will get me to work and back without to much fuss and be able to used occasionally on dirt tracks on the weekend for XC. Round trip to work and back is about 15km's.
I have ridden a BH Emotion Cross, with a 350W hub, limited at the top end to comply with Australian laws of being a pedalec. Ideally something 4-5 times more powerful.
The bike I am looking to use is a 2005 Scott MC30 dual suspension bike. There should be enough room for batteries in the frame.
My requirements are as follows:
- 20-30km range with low to moderate pedalling
- 50-60 km/h top speed
- mostly flat riding in Melbourne with the occasional small hill
- I weigh about 80kg
Currently I am looking at the following options:
- Crystalyte HS3548 or HT3548 hub, not sure which one or to get a sensor or sensor less hub
- 26in wheel, more efficent but may overheat the hub with 72v, or 20inch or 24inch wheel, more power and the hub should run cooler but lower top speed
- Cycle Analyst 3 to monitor the battery and limit the current to the hub if needed, as well as set min cut off voltage levels for the battery
- Battery, 72V 10ah Lipo made up of the following:
8 x Turnigy nano-tech 5000mah 5S 25~50C Lipo Packs, 4 groups made up of 2 packs wired in parallel and then the 4 packs wired in series.
- controller, I am not sure if I need a 30amp, 45amp or 65amp controller. I am currently looking at the 18 FET Low RDS MOSFET Overclocker Ready LYEN Controller which is tuned for a 72v system and can take up to 65amps.
Please let me know if there are other more appropriate hubs/type of battery/battery voltage/battery configurations and controllers that may be better suited.
Thanks
Dan.
