Reiver prototype.

#neverbackdowncountry

KOLARP re-imagined for a shorter travel package.

Gary has been riding the Auckland Cycle Works Reiver, carbon-alu prototype, since October 2022.

This Reiver has also been raced a few times and has taken the rider to some podium places at local races.
Gary got a podium at the NDH Hamsterley TT in 2023, Aspen got a win at the NDH Eastgate TT in 2024.

The heart of the short-travel KOLARP^[X] variant is that the BB is mounted on the lower linkage.
This delivers some amazing benefits:

1. Standing up increases the leverage over the shock, releasing more suspension travel.
2. Sitting down decreases the leverage over the shock, restricting the amount of suspension travel.

This is a very special thing, because Reiver automatically adapts to your weight shifts, increasing travel and traction as you lift out of the saddle, yet limiting travel and increasing efficiency as you transfer more weight into the saddle. It’s like the most sophisticated system of lockouts and travel-adjusters, but it responds automatically to your natural weight-shifts.

3. Curved axle path delivers a rearward axle-path in the beginning of the stroke, increasing suspension effectiveness.
4. Perfect braking anti-rise delivers the most amazing chassis stability. KOLARP keeps the suspension active and prevents extension under braking.
5. Zero pedal kickback.

Although this model looks very polished and ready to ride, it will see significant revisions and needs at least one more prototype before it’s ready. This prototype was built with 8-way adjustability within the suspension linkages, and many adjustments to the shock have enabled us to learn what this machine is capable of and refine the KOLARP^[X] suspension design.

The KOLARP suspension concept as used on this Reiver design is protected by our own KOLARP patent GB2611590, published 3^rd January 2024.

Bikes with KOLARP suspension are available only from Auckland Cycle Works.

We are currently planning for Reiver to be released as two variants.
