pretty much anything that requires standing up just doesn't work well on those bikes. i agree they are for crusing around, not racing around. i rode my dad's one time because my commuter was in the shop, it took me for ever to get to work, it was super awkward to try and climb out of the seat. they do descend rather nicely though.
