The Marin Alpine Trail E2 Electric Bike is Their top-end Alpine Trail, ready to tame the roughest and toughest of trails. For the best of the bunch, they've packed in the big-dog Shimano STEPs EP801 system and a long-lasting 630Wh battery, Fox 38/Float DHX2 Performance Elite suspension and a blend of Shimano XT and SLX 12-speed, including powerful 4-piston brakes.SERIES 4 ALUMINUM FRAMEAlpine Trail 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.MULTITRAC SUSPENSIONThe Alpine Trail E features the same great, proven MultiTrac suspension technology, but optimized for the Shimano STEPS system. With this combination there is no need for platform or lockout levers, just get on and blast up the hills.MIXED WHEEL SIZES29” front and 27.5”+ rear wheel sizes are the ideal combination for the Alpine Trail E, with larger front wheel easily rolling over most any trail obstacle and offering the best cornering traction, while the burly 27.5” x 2.8” rear setup adds playfulness and enhances acceleration and braking traction.DROPPER POST OPTIMIZEDThe modern day trail rider needs their saddle out of the way at times, while low-slung frames require longer length posts. On the Alpine Trail E, seat tube lengths have been minimized, along with minimum insertion depths, so that riders of all sizes can get the proper extension needed.Marin Alpine Trail E2 Electric Bike HighlightsShimano STEPS EP801 systemFox 38/Float DHX2 Performance Elite suspensionShimano XT/SLX 12-speed drivetrain w/10-51t cassetteTRP DH-R EVO 4-piston disc brakes
