I've seriously considered the Schlumpf but the simplicity of the dual chainring without derailluer appeals to me as well. I really enjoyed the Xootr I test rode so the Swift should be even better. I did notice that the Xootr I rode needed to have the derailleur adjusted or dialed in as the shifting wasn't exactly great but the dynamics of the bike itself were quite impressive. I am big guy and I didn't feel any flex at all in the frame. Should be a fast fun ride. I'll get loaded up on gears to try out.
I'll post pics as sort of an evolutionary tale as it progresses. I am still deciding on color choice at this point. Too many choices sometimes are a PITA!
