Marin Rift Zone E XR 2025 eMTB

XR stands for EXTRA RAD. We turned the Rifty E up another notch with this one – RockShox Lyrik Ultimate fork and Super Deluxe Ultimate Shock, Vee Tire Co rubber, Shimano XT drivetrain, next-gen Shimano EP801 motor, SRAM Code 4-piston brakes. And the cherry on top? SRAM AXS wireless shifting and a wireless RockShox Reverb dropper post. Our highest spec, highest tech Rifty E ever.

Rift Zone E models are built upon our Series 4 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing, giving the rider the highest-end alloy frame that Marin offers, compatible with modern coil or air shocks.

The Alpine Trail E features the same great, proven MultiTrac suspension technology, but optimized for the Shimano STEPS system, with 140mm of suspension for the best on-trail experience.

Shimano’s STEPS system is both powerful and lightweight, with the mid-drive motor down low to help ensure that the Rift Zone E performs like the analog version, but with a 250W boost. Three levels of power give riders options to balance electric power, speed and range. Electric assist up to 20mph in the US, 25km/h in Europe.
