well if girly is a lot smaller than u ull be in troubles anyways... I think it will be better get a bike for herself u know... besides... what if she doesnt like the track?? U'll be stucked trying to sell that stuff... or what if the relationship ends??? u can get the bike back or give it to her or sell it or sometihng.. wt-hell r u going to do with a tandem as a statue in the garage?? think in those things 1st hehehe... If she was my wife i would think in the posibility of getting a tandem... but nah! my wife wont ride in a track ever! hehe...
