Vehicle, Mobility and Transportation Design Superstrata Bike and Ebike by Arevo Superstrata is the world's first customized unibody bicycle frame 3D-printed from carbon fiber composite. The Superstrata bike frame touts a unibody construction that is free of joints and bolts, which improves not only the strength but also adds aesthetic to the bike. Each frame can also be custom 3D printed based on the owner's body measurements and riding preferences, meaning it is unique to each rider. The design is further accentuated by the unconventional absence of a seat tube, placing Superstrata in a place of its own.
