Riding in traffic especially stop/start is not something you want to start doing til
you have a few hundred kilometers experience on the bike. Starting bents is different
enough that you need lots of practice and get in the habit of downgearing automatically when you stop. If you stop on an upgrade in too high a gear and in
traffic you will never get going and getting off the machine to manually change
gears is harder on a bent than DF, especially ones like the Challenge models. Use BMX or platform pedals to start with as clipping in adds too much distraction to everything else. Bents wobble back and
forth a lot more than DF bikes do-you will look like a 6yr just out of training wheels
initially on the bent, after 3-400km this will be much better. 62cm seat height
on the Seiran might be a bit of stretch for you. I have sat on a ridden briefly a
Baccheta Aero that has about the same seat height and you learn to sit up
at a stop to reach the ground. Sitting up is easier with above seat steering than
below seat as you don't scoot forward in front of the bars, so that would be a consideration. The 52 cm seat height of the Wizard would be friendlier. Steve
