Features and technologies

Two-position axle for wheel size adjustability
The two-position axle guarantees a balanced geometry and ride feel while swapping wheel size.

Smoothlink™ suspension
Smoothlink suspension is efficient yet supple when you’re on the pedals and across a wide range of gears. It features a controlled end-stroke and a rate-curve that feels more capable than the travel would suggest.

Dyname™ S4 Pro
Dyname™ S4 Pro, only available on Powerplay, is incredibly powerful and is truly a leader among e-bike motors. We designed the power curve within the software to deliver the 108Nm smoothly, allowing you as the rider to soft pedal around tight switchbacks or drop the hammer through a chunky, punchy, portion of trail.

SMOOTHWALL™ Carbon
Smoothwall carbon uses one of the world’s most sophisticated carbon processes to deliver industry leading stiffness-to-weight, ride quality, and durability.

Size Specific Tune
Size Specific Tune ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Our design team does custom shock tunes based on real world field testing, and adjusts each tune for specific frame sizes.

RIDE-4™ adjustment system
The RIDE-4 adjustment system allows riders to quickly fine-tune their geometry with a single Allen key. Four configurations are possible thanks to one rotating chip.
