My fatbike will cruise over anything, rocks, gravel, sand, soft tall grass, mud, snow, sticks, etc.. I can run 5 psi in the tires for the soft stuff requiring grip. At 10 psi, these tires are very stable on the streets; small patches of dirt, sand, gravel, etc. are no issue. The disc braking is very efficient, cornering is easy, and the speed attainable is mindblowing to people watching you fly by on a bicycle. I now ride it more frequently than I do my home converted street bike(see Dearmissmermaid's posts for the same conversion kit) which is fun and lighter than my Radrover. By the way, my self converted e-bike has belt drive rather than chain. I think it's the future for casual cruisers.
