Which motor will get me up hills easily?

[lieinking1]

I have a rear drive motor e bike but it can't get me up some hills. I'm 100kg without much stamina. I have seen on youtube some of the electric mountain bikes in high gears going up pretty steep muddy hills. I'm not planning on going off road but I'd like to be able to get up steep ish hills without much effort, even if it is slowly. I've been thinking to get one of those ebikes with a bosch motor because the bosch motors and their torque are stated on that website, and these bikes say which motor is on them. So I'm wondering with my weight how many NM of torque I will need on one of these motors to get up hills easily? Or even on other motors.

Post details of what exactly you already have, motor, controller and battery, so that we can propose options.

You need more power, which doesn't necessarily mean you need a new motor. It's not the motor that determines the power you get, it's the controller, and the battery needs to be able to provide the power.

In some cases, you can get what you need with what you have for no additional cost.

The bike is an ADO AIR 20.

THIS?

Which version??

Just so we get an idea of the gradient , could you say which hill you are struggling with at the minute ? We can check how steep it is and how much power you would need to get up

Oh it's single gear ! Won't help with steep hills !

Some info here https://www.reddit.com/r/ebikes/s/ap9VdXiT70

It doesn't look an ideal choice for a 100kg rider with limited stamina in hilly areas tbh

Maybe try a shunt mod to the controller ?

I suspect the fact that it has a torque sensor and you say you have little stamina that is the problem. A Bosch motor won't solve that problem. Also as @Peter.Bridge said, single gear doesn't help either .

Yes that one.

I thought a mid drive motor with gears would solve the problem if it has high enough torque like 70+ NM. Or would that still be a struggle to get up hills?

I get to around this point on this hill before I stop usually. https://www.google.com/maps/@51.4806075,0.0035728,3a,75y,146.35h,69.53t/data=!3m7!1e1!3m5!1sgLr-aeVj_NHyyEp4QTzNYw!2e0!6shttps://streetviewpixels-pa.googleapis.com/v1/thumbnail?panoid=gLr-aeVj_NHyyEp4QTzNYw&cb_client=maps_sv.tactile.gps&w=203&h=100&yaw=321.1282&pitch=0&thumbfov=100!7i13312!8i6656?coh=205409&entry=ttu&g_ep=EgoyMDI0MTAxNi4wIKXMDSoASAFQAw==

Single gear on hills is a disaster.
