Hey all,
Im looking to make a simple ebike out of:
2nd hand starter motor
spare car 12v battery
Not going to be too complex. Im thinking of welding a rail or rails onto the frame of the bike to allow me to adjust the position and chain tension of the starter motor setup.
Im thinking of chaining it to the pedals with a seperate cog. That idea would allow me to have use of the full 21 gears but i wouldnt be able to have my feet on the pedals, id prob just weld some foot rests somewhere infront or behind. I want to know tho if anyone has tried that, im a bit worried about stability.
Also do startermotors have continous power output or it is in large surges? i only ask this because of the noise they make when i start my car
Would i be better off just having a single gear on the rear wheel? Id like to be able to spin the wheel in the wet on full charge but gear it to pull well up hills ( i have some nasty long hills in my suburb lol).
I understand the safety issues with a car battery but im cool with that
Also for the starter to the front or rear wheel where are the best placements?
I was thinking if to the front id put it in the centre of the bike and if to the rear id sit it infront of the rear brakes with a few brackets.
And if i had it above the rear brakes, would i want to go for friction drive or chain drive? I hear that the chains break often.
thanks for putting up with my lack of understanding!
