I do really want to build a heavy (140kg/300lbs, including a rider) full-suspension direct drive bike. As I see it now it will be 72v 65ah + ~3kW direct drive motor. The only thing that stops me - I have never tried direct drives and have no idea how they behave: power consumption on low speed (20kmh/12mph) in Watts, how power consumption changes from low to above average speed (40kmh/25mph), power consumption on top speed. And the most important question - range.
Let's say I am cruising 30kmh/18mph average, let's say the route is 1km/0.6mi elevation per 70km/44mi distance (which is what I would describe as "flat with small hills"). What range/distance (no pedaling) to expect?
My estimations show 80km/50mi as absolute maximum (no pedaling).
Any thoughts?
Would also appreciate just some data (for direct drive motors) like: battery voltage/cruising speed/power consumption/terrain/pedal assist.
Info from mid-drives will work as well (at least it's better than nothing).
