Recumbent based on QT50. Frame modified with new upper shock mount, foot pegs out front mounted on mountain bike stem, cross tube and seat mount. Many mods including front disc brake in stock hub with Wilwood caliper and custom mount. Custom made gas tanks with hockey puck gas cap. Battery, CDI, wiring stuffed in modified Walmart pencil case. 2.5" rear tire. I put a ton of miles on this thing. Very comfortable!
