I'd have to say its looks and storage space. I can only own so many
more bikes before I'm out of space. I'm also looking at transporting
the thing. I'm a few miles off the bike trail and getting there
could be a problem. I think the short wheel base will fit on my yak
rack pretty easily. I guess I'll have to agree we all probably have
several reasons for building SWB. Is there a reason to choose over
seat stearing rather than underseat stearing?
