this is a nirve switchblade , it has the scooterguy system mounted with freewheel crank it came with a coaster break witch wont work with the freewheeling crank , so a threaded rear hub flipped around and laced to the original rim worked perfect to mount a scooter drum break . next the rear hub will have to be replaced with an internal 3 speed that has a drum break also , woth will work from the sick bike parts double break lever , i'm waiting for the titan motor . from thatsdax.com
