Transition Regulator SX Carbon Eagle 90 E-Mountain Bike 2026

The Transition Regulator SX Carbon Eagle 90 E-Mountain Bike is what happens when Transition builds an e-bike on their own terms — no compromises, no excuses. Its lightweight Bosch Performance Line SX motor powers out 55Nm of torque through a mixed-wheel chassis with 150mm of travel and a geometry that prioritizes fun over brute force. The 400wh battery offers enough juice for everyday riding with the option of a 250wh range extender for bigger days — perfect for riders trying to strike the right balance between weight and range. It's more trail bike than e-bike, and that's exactly the point. This build features Rockshox suspension, SRAM Maven Silver brakes, and SRAM Eagle 90 T-Type drivetrain components for smooth shifting under load.
