Hi, I'm going to build an e bike, and I just want to know a few things, my area is a very flat area, and I would need to move as too as 40 km or 50km in an extreme situation.
I'm 90 kg, so I would like to know if it is ok with a 500W motor or I should need a 750W or 1000W motor??, ( I don't need to go faster than 25km/h perhaps 30km/h),
I've decide to use a 48V sistem, because of the idea that I'll need less amperage to get the same Wattage.
But how many Ah would I need, to be able to drive for around 40km or 50km?
