as the title says.. i do have an itch and it's getting worse. i'm so tempted. the type i'm looking for are like the verge X20, and those that are very similar to a road bike but in 20" wheels.
the thing that's holding me back is since the wheels are smaller, would it take more effort to pedal to keep up with my friends on regular road bikes?
i know it depends on the engine.. but in general, anything about the gear combinations/ ratios that can allow me to keep up and not fall too far behind. at the same time, give me the massive gear to help me climb without putting too much pressure on my knees (recovering from injury)?
