We built up the Amp frame today with some choice kit, keeping it simple with single speed and pretty burly parts.
I was amazed how easy it was to fit the integrated headset, and how light it was! The Amp is probably the closet mountain bike I have ever ridden to a BMX, it really is SO slammed, tight and low. And at a frame weight of only 4.5lbs (for the long size), it will be a GREAT bike for dirt jumping, street and pump tracks.
There are a few things I plan to in the frame change before full production, but the geometry is pretty dialed (shout out to Scott Alleyn one of our riders in Canada) for help with the design, and in particular the geometry. The changes are pretty simple tweaks that will not add any weight, but should improve the aesthetics and performance.
So far I have only had a chance to do some parking lot testing, but it feels really planted. The BB is so low that it just tears round corners, and it feels stiff and responsive under pedaling and J-hoping and manualling are easy as anything!
Massive thanks to Rob Cole for all his help with the spec and build!
