I am considering a Rad Wagon to do grocery shopping and light errands, not hauling bricks or heavy duty stuff. My main bike is a mid drive commuter/urban and I have a rear hub geared 350 watt for guests. While I would love to buy a mid drive cargo bike, the additional costs don't seem warranted since this will not be my main bike for riding. I live in FL, I'm 205 lbs and there are really no significant hills to deal with. I'm not sure of the magnetic drag when coasting down the gentle hills that I ride. Is it significant? Also would appreciate opinions on the overall performance of the motor when carrying a load.
