I am seeking the experience of Rad Runner users on the single speed setup. I am interested in the Runner for utility use. The Rad Wagon is more than I need. I have a Qualisports Volador with a 350 watt/40 nm motor vs the Runner 750 watt/80 nm. The Volador is 40 lbs vs the Runner 60 lbs. Living in Florida, I can ride the Volador easily in the highest gear (14 tooth) with a 52 tooth chainring using power level 1 with occasional blips of the throttle on inclines (can't really call them hills). The Runner has a 16 tooth sprocket with a 52 tooth chainring. My intended use is grocery shopping/light errands, flat terrain, total trip distance 10-15 miles. I thought of the Runner Plus but I have no need for the passenger package and given the fact that I ride sidewalks and smooth pavement the fork is not a necessity for me. I do plan to upgrade the seat post and seat. Experience and feedback on likes/dislikes of the single speed would be appreciated.
