2016 Amp Jr - Black/Orange
2016 Amp Jr - Black/Orange
Built for getting into BMX, the Amp JR is a modified version of the Amp 20. Still based on a 20" wheel set, the AMP JR has smaller frame, bars and stem making this bike easier to manage while still maintaining a true BMX feel. 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 down time to a minimum with low maintenance components like fully sealed rear cassette and sealed Mid bottom bracket.
