I am just looking for some help in comparing these two bikes. I dont really understand the difference / benifit of the geared bike vs SS.

I currently ride alot of road and cross country mtb. I am just tired of taking my fancy mtb bike downtown for urban rides. I suppose a bike like either of these will be much more adapt to wheelies, manuals and drops.

Just looking for a fun bike to ride around in. nothing to fancy if anyone has any other options in the same price range.
