not only is it too small for you it has all un-sealed bearings. which are just going to be a headache
20"tt is something someone who hasnt hit 5 ft yet should ride. even a 20.5 would be pushing it for you.
you could get the gap, which is the next model up. that has a 20.5
or for 20 dollars more, get the whip. which is a 20.75tt. and you get a better frame, double wayy back rim, sealed cassette and sealed bb.
and still the whip is only 50 dollars more than the launch
