The 2026 Altitude Powerplay is Rocky Mountain's enduro e-MTB, built around the in-house Dyname S4 Pro drive system (250 W nominal, 1000 W peak, 110 Nm per the spec sheets) and a 720 Wh two-bolt removable battery. The optional Overtimepack 2.0 adds 314 Wh on the down tube, and the Jumbotron display is integrated into the top tube; no app is required.
The LC2R suspension gives 160 mm of rear travel with a 170 mm fork (frame designed for 170–180 mm). Size SM rolls on 27.5-inch wheels, MD–XL on 29-inch, with an optional MX link for mixed wheels on MD–XL. The RIDE-4 chip offers four geometry positions; frames are SMOOTHWALL carbon (Carbon 70) or FORM alloy (Alloy 30, Alloy 50), all with a threaded BSA bottom bracket and coil-shock compatibility.
