smallwheeler - Do you know of any mini velo bikes that would not be too difficult to get ahold of in the US that can take a wide tire? It seems like the fork limits tire size on many of these. I am toying with putting together an electric bike that can take on Seattle hills. I like the torque of the smaller 20" wheels when assist is applied, not really concerned w/ top speed, steel frame highly preferred, as is ability to mount disc brakes. I have considered converting a bmx but am worried that simply getting a longer seat post will still leave compromises in comfort. I like the riding position of the mini velo and the space within the frame to mount a battery on the down tube. Thanks!
