Krooztune AMFLOW Gravity Linkage

Engineered Control. Expanded Capability and a ride test report here :  Amflow Gravity Linkage TESTED

The Krooztune AMFLOW Gravity Linkage is a precision-engineered suspension upgrade developed to unlock the full descending potential of the AMFLOW platform while preserving the bike’s intended chassis balance and pedalling efficiency.

Developed through real-world testing and kinematic analysis, the linkage increases usable rear wheel travel and refines suspension progression to deliver greater traction, improved mid-stroke support, and controlled end-stroke performance for aggressive trail, gravity, and e-MTB riding.

This is not simply more travel — it is better-controlled travel.

Ride Dynamics

Increased Usable Travel

An additional +11 mm of rear wheel travel allows the suspension to absorb larger impacts while maintaining composure and stability at speed.

Balanced Chassis Behaviour

Linkage geometry is revised to maintain correct ride height and weight distribution, ensuring predictable handling both climbing and descending.

Mid-Stroke Support

Refined leverage characteristics provide improved support through the centre of the travel, keeping the bike riding higher under load for enhanced cornering confidence and reduced rider fatigue.

Controlled End-Stroke

An additional +5 mm of controlled end-stroke increases bottom-out resistance, allowing riders to push harder into rough terrain without harshness.

Geometry Preservation

A subtle  +3 mm bottom bracket height adjustment maintains pedal clearance and chassis stability despite increased travel.  It’s tiny tho  , the bike sits in more naturally downhills due to the linkage action , so delivers a slightly lower ride feeling .  It’s very settled and planted into turns under brakes 

Engineering Philosophy

Krooztune applies motocross-derived suspension principles to modern e-MTB design.

Rather than chasing travel numbers alone, the AMFLOW Gravity Linkage reshapes the suspension’s leverage progression to improve how the bike rides throughout the entire stroke — from small bump sensitivity to full compression control.

The result is a suspension system that feels planted, supportive, and predictable across a wider range of terrain and rider input.
