All Rad Power bikes usually weight around the same at +62 lbs and not geared for very fast pedaling without some level of power assist from PAS and/or throttle. You won't get up to the same speeds like a lighter pedal bike on the same level terrain. Radmini is great for compact size if you need to transport or store in limited spaces, heavy load hauling up to 275lbs total weight, all terrain capabilities, all weather capabilities, leveling out hills, and negating head winds.
Any type of headwind or incline makes these heavy bikes 2X-3X more difficult to pedal at speed without power. I once ran out of power about 1/2 mile from home (headwind of +15 mph and an incline) and it 2-3 mph was my max speed. I just had to do that once to realize never ever again.
You can still ride these bikes without power at PAS 0 or PAS level 1 with very minimal assist. You still have the full power 750w throttle available if you need a quick boost to get across intersections or up small inclines as needed.
