Rocky Mountain Altitude Powerplay Alloy 50 — 2026 current listing
The Rocky Mountain Altitude Powerplay Alloy 50 brings together Dyname S4 Pro, 170 mm / 160 mm suspension, and a form alloy chassis for enduro / full-power riding.
Why it belongs on the shortlist
Built for riders who prioritize descending control, repeated rough hits, and confidence on steep technical terrain. Its long-travel chassis rewards committed line choice while the drive system keeps high-vertical days moving.
Motor and battery
The Dyname S4 Pro system delivers 108 Nm and pairs with a 720 Wh battery. This configuration puts climbing support and repeatable vertical at the center of the ride.
Real-world range changes with elevation, support mode, rider mass, temperature, surface, tire setup, and battery condition. Use capacity as a comparison point and plan routes with a practical reserve.
Suspension and control
170 mm of front travel and 160 mm at the rear are paired with the RockShox ZEB Select RC fork and FOX Float X Performance shock. The 29 inch wheel configuration supports the bike’s intended balance of rollover, cornering response, and descending stability.

Start with the manufacturer chart, then compare reach, stack, standover, wheel setup, and dropper insertion. Riders between sizes should decide whether they prefer a more agile cockpit or a longer, more stable feel.
Setup for the first ride
A qualified technician should verify the wheels, brakes, fastener torque, cockpit, suspension pressure, tire setup, firmware, and complete drive-system operation. Fine-tuning sag, rebound, tire pressure, and controls to the rider makes a meaningful difference on trail.
Battery care
Charge with the supplied system in a dry, ventilated area on a stable surface. Inspect the battery and charger before use, follow the manufacturer’s storage guidance, and keep the system away from impact, extreme heat, and water intrusion.
Warranty
Rocky Mountain five-year frame terms; component terms vary. Refer to the current manufacturer terms for registration, original-owner, component, and territory requirements.
