After I got hit by a car I re-built my Easy-3 and went with 26" wheels in the rear and a 20" wheel in the front; I have my reasons. After some months I've noticed that my rear wheels now need to be re-trued (?). So now I'm thinking I'd like to lose the spokes all together and go with wheels that can withstand the stress. Is there such an animal? Who makes it? Again; I have my reasons for going with bigger wheels.
