I live in a very hilly place around 20-30% gradient.
I’m wondering will a 280kv motor with a 2:1 pulley ratio pull a 160 pound guy up thowse hills or would a 3:1 ratio be better
6s battery 2x 5000mah
I think 16mm witdh timing belt
What size wheels?
Gearing? (ex. 15t to 36t)
We need to know a lot more
Also, a 2:1 ratio probably won’t be enough to get you up anything more than 15% assuming your using 9mm belt
You can put all your specs in there and play with them. Even the steepness of your hill.
I had a similar scenario, I am about 10kg lighter, went for 10s, 13t/36t and mono 190kv 6374 with Kegel wheels. Works really well, can accelerate up most hills.
He’s not using 190kv and he has a higher gear ratio than you, he will not get up hills.
I know, thats why I shared a setup that I know works for hilly areas.
You need around a 3:1 ratio to get up a hill that steep and at least two motors to move up a hill with 30% incline. 30% is steep. There is no way you live around hills that steep unless it San Francisco, Los Angeles, or New Zealand.
