The SuperQuick uses a 6061 aluminum frame with hydroformed downtube, reinforced gusset and reinforced rear dropouts. Its low-standover geometry is designed to let smaller riders use 20-inch BMX wheels. The single-speed drivetrain uses a KMC Z-410 chain, and the rear coaster brake is operated by pedaling backward.

The reinforced full CrMo rigid fork, double-wall aluminum rims, 20 x 1.95-inch tires and BMX platform pedals complete the build.
