I got my Radwagon in 2018, I think. I've got almost 6000 miles on it. (Spring, Summer, Fall & Winter)
I am an old bike nut going back 50 years. The radwagon was my first ebike and my first cargo bike. It has become my run to the store bike.
I my problems with the bike have been minor and routine for the most part...
--The controller going out at 1000 miles but the Rad Power people replaced it at no cost, after some email communication.
-- The design of the bike makes changing the rear wheel/tire a pain in the butt and the nuts tend to loosen themselves.
--I had a lock washer on the rear axal shear off at about 2500 miles
--Ordering a new battery was a problem. They sent the wrong one 1st time.
I have bought a new ebike because the Radwagon was too big to transport with ease, so I don't ride it as much as I once did. It is still part an active part of my fleet.
