Usually not. It'll be fast at the start, but a small crank will limit top speed unless you can turn the pedals really fast.
Not Haro
It's a size measurement, taken from the center of the seat tube(the tube that the seat post goes into), along the top tube, and to the center of the head tube(the tube that the fork goes through at the front of the bike).
working from back to front: tyre, innertube, rim, spokes, nipples, hubs, frame, cranks, pedals, sprocket, seat clamp, seat post, seat, bars, grips, bar ends, stem, headset, top cap, forks, hubs, spokes, nipples, rim, innertube, tyre :)
in terms of modern bmx the logest that people use today is either 21" or 24" top tube
ANSWER: I believe that Haro is the best BMX complete bikes for the money. I love my Haro BMX race bike.

It's a BMX racing bike for beginners. What we would call a "Junior" size (pre-teen). It's a strange mix of entry level and high end. For example, it has a hi-ten steel frame, plastic pedals and unsealed hubs, yet it has a sealed bottom bracket and a Cro-Mo three piece crank. It's a small bike as it has only a 19 3/4" top tube and an "upside down" style handlebar stem.

The crank sensor is mounted on the top of the transmission bell housing.
