I think sensored brushless systems are better for this bikes.

LRP Sphere with Vector 3 or 4 stars or Novak GTB/ Velociti 6.5 or 5.5 are great.

For doing wheelies you will need good slick tires (PMT).

If you want a rocket, the Hyperion VX 3.700mA lipos fit in the battery case (you have to cut a little of plastic) and are not too expensive.
