Slack 63.1° head angle, 160mm travel and a long 1283mm wheelbase — composed in the chunk, confident when it gets steep, and stable through fast corners.
Altitude Powerplay 2026
How current the bike is — newer chassis, motor and battery score higher. 10 = brand-new, 0 = legacy.

The Altitude Powerplay is Rocky Mountain's full-power enduro eMTB, built around the in-house Dyname S4 Pro motor. The headline figures are 110Nm of torque and up to 1000W peak from a 720Wh removable battery, with an optional 314Wh Overtimepack 2.0 range extender that bolts to the downtube. Travel sits at 170mm front and 160mm rear on the LC2R virtual-pivot platform, putting it squarely in big-hit enduro territory.
Geometry is aggressive: a 63.1 degree head angle and 505mm reach on the XL in the neutral RIDE-4 POS.3 position, with the rotating RIDE-4 chip offering four geometry and suspension-rate settings from Slack to Steep. Chainstays are size-specific (448mm on M and L, 458mm on XL), and the FSA Orbit NO.85 reach-adjust headset adds further tuning via 0 and +/-5mm cups. Size SM runs 27.5in wheels front and rear (with a slacker 63.5 degree head angle), M to XL run 29in, and MX (27.5 rear) is available on sizes MD to XL via the MX link.
Three builds make up the range. The carbon-framed Carbon 70 is the flagship, with a Fox 38 Factory fork, Float X2 Factory shock, SRAM Maven brakes and an Eagle 90 Transmission drivetrain. Below it sit two alloy bikes: the Alloy 50 swaps to a RockShox Zeb Select RC and Fox Float X Performance while keeping the Eagle 90 transmission, and the Alloy 30 brings the entry price down with a RockShox Domain Gold, Marzocchi Bomber Air shock and a Shimano Deore 12-speed drivetrain. All three share the same frame platform, motor and 720Wh battery, so the spend buys suspension and drivetrain rather than power.
What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
More planted than poppy — better on steep terrain than tight, fiddly singletrack.
Balanced front-to-rear in L (FC:RC 1.86) — weight sits evenly between the wheels.
Climbs well — a 77.1° seat keeps the front planted. 1000W of peak power and 108Nm of torque — among the most powerful e-bike motors made.
Rewards commitment; it should feel calmer as the speed rises.
Brilliant on fast, rough, steep terrain; less fun on tight, mellow trails.
