Ive been commuting on recumbents for 11 years now. Low racers do not make good commuter bikes. They are too low, you will be looking a cars wheels, drivers won't see you, not to mention semi trucks. Its scary! Too layed back, it's hard to balance, you will find yourself on the ground on the first sand patch. Too heavy, you are using solid steel parts. Ive only ridden a moving bottom bracket bike once, a cruze bike Vendetta. Very strange sensation steering and pedaling, they say you get use to it, but cadence has to be slow due to the dynamic imbalance on the fork, makes it wobble at high speed. Yes, I prefer long wheel base and web seats, though my current commuter is a Vision R40 swb with a tail box. It fits in the saturn. Good luck on your build.
