Hardtail Heaven Paradox 27.5” Electric Street Bike
Built for the Streets. Powered for Everyday.
Most electric bikes look the same — oversized frames, bulky batteries, exposed cables, and awkward motor systems that take away from the bike’s design.
The Hardtail Heaven Paradox 27.5” Electric Street Bike was created to change that.
Built from the foundations of our Sinner Street Jump platform, the Paradox takes everything riders love about a capable hardtail and adds a discreet, intelligent electric assist system designed to keep the bike clean, lightweight, and undeniably cool.
Instead of relying on oversized downtubes or bulky external batteries, the Paradox uses the innovative Keyde all-in-one rear hub system. The motor, battery, controller, and sensors are all integrated into a compact rear hub, creating a fully wireless setup with no clutter and no compromise to the bike’s appearance.
The result is a fast, practical, and stylish electric street bike built for commuting, urban riding, pump tracks, and everyday adventures.
