I picked up a baritone uke last year to take with me on my bike, it didn't work out. My fault, I should have gone to a music store to find one instead of ordering it. The strings are too far apart, once I get use to it then go back to the guitar, I'm all messed up. So over the winter I plan to look locally for something else to trade a really nice ukulele in on. I really like the size and sound of this uke though.
It would be no problem carrying it on the bike. My guitars are "dreadnoughts", would need a trailer and someone to help peddle for either of those.
