Built for getting into BMX, the Amp 18 is a sized down version of the Amp20. A smaller frame, bars and stem and 18-inch wheelset make this bike easier to manage while still maintaining a true BMX feel for a smaller rider. 25/9 gearing, 3 piece cranks and added clearance on the frame, fork and brake for wider aftermarket tires means this bike has all the basics as well as the newest features in BMX. Keep downtime to a minimum with low maintenance components like fully sealed rear cassette and sealed Mid bottom bracket.
