DIRTE Paratu CP - Enduro

Paratu CP - Enduro

Carbon eMTB · Enduro · Complete bike

The lightest full-power eMTB.

A full-carbon monocoque enduro eMTB built around the Maxon BIKEDRIVE AIR S — co-developed with Maxon since 2020. Concentric Pivot suspension: zero-bob on the climb, groundtracing on the descent. Factory to rider, no middlemen.

Calm on the brakes. Quiet on the climb.

The kinematics behind the ride. Read the Dirt for the feel — tap Lab for the curves, the numbers and the engineering.

Descend

Brake late and hard into a steep, loose chute and the bike stays planted — no skipping, no pitching you over the bars. You hold your line, and your nerve.

Anti-rise is held near 49% at sag and trends lower toward bottom-out, so braking forces neither lock the rear solid nor jack it down under you. A mildly rearward axle path lets the rear wheel move up and back through square-edge hits instead of fighting them. The chassis keeps its attitude instead of pitching forward — more grip, more control on steep, loose terrain.

Axle path

top-out sag bottom 100% 50% 49.1%
Anti-rise % across rear travel — sub-100% throughout.
What it governs
  • Anti-rise — how braking forces load the suspension. Kept sub-100% throughout so the rear never jacks down or locks solid under hard braking.
  • Axle path — the arc the rear wheel travels. Rearward early to absorb square-edge hits rather than hanging up on them.
  • Leverage curve — near-linear (~2% progression) so grip and support stay consistent through the stroke — easy to tune with air or coil.

Climb

Sit and grind and it just goes — power down without the bob, the rear end calm and efficient. Nothing is fighting the suspension on the way back up.

Anti-squat sits at 97.3% at sag in climbing gears — high enough to resist squat under power, yet the rear stays fully active over small bumps. That's the Concentric Pivot paradox: pedalling efficiency and small-bump traction at once, normally contradictory goals. Pedal kickback is held to 3.0–3.5°, so square hits don't yank the cranks back under your feet.

Anti-squat % across rear travel — high at sag, easing deeper in.
What it governs
  • Anti-squat — ~97% resists squat under power without locking the rear end, so it pedals firm but never dead.
  • Pedal kickback — 3.0–3.5° — low enough that impacts stay off your feet, even deep in the travel.
  • Concentric pivot — main pivot on the BB axis, horizontal shock, no idler: fewer parts, less friction and noise, predictable service.
