Looking for best bang for buck E Bike. I know very little about them. Can't go over budget unless multipurpose, ie dirt bike.
It needs to handle the following;
90kg rider
20km distance on single charge
Available spare batteries
19km of flat road and about 1km of decent hills to climb, (25 degree slopes?) Good example of hills
Edit:
Decent speed, say 40-60 25km/h
