720 Wh
Battery
Full-power enduro bike on Rocky Mountain's own Dyname S4 Pro motor, which is not a third-party system. The torque sensor is stated on Rocky Mountain's Dyname S4 Pro page (bikes.com/pages/dyname-4): 'a torque sensor that precisely measures chain tension'. The spec table gives 110Nm while that same motor page says 108Nm; the spec table figure is recorded. 160mm rear travel, 170mm Fox 38 Float EVOL GRIP X2 Factory fork, Fox Float X2 Factory shock, SRAM Maven Silver 4-piston brakes (rotor sizes not published), OneUp V3 dropper 150-240mm by size, RIDE-4 adjustable geometry. The spec table calls it a 'class 1 eMTB System' but publishes no top speed. The 720Wh battery is removable and a 314Wh Overtimepack 2.0 range extender is sold separately. Price is the bikes.com sale price read 09/29/2026, down from a regular $10,799. 29in wheels on MD-XL, 27.5in on SM; SM was sold out when read. The weight field on the spec table reads 0, so weight is blank. An Alloy 50 build lists at $5,529 (regular $7,899) but was sold out in every size.
