WHO IS CRESTLINE BIKES?

Born out of Southern California and bred on demanding terrain, Crestline Bikes was founded by Troydon Murison and Mark Clemens with a straightforward mission: eliminate compromise in gravity-focused mountain bikes and eMTBs. Frustrated by off-the-shelf electric mountain bikes that felt clumsy, under-suspended, or overly prioritized commuter ergonomics, Crestline paired race-level suspension tuning—collaborating directly with kinematics specialists like Cascade Components—with uncompromising carbon construction and the best technology available.


CRESTLINE MODELS


RS181.2

The Crestline RS 181.2 represents the latest generation of Crestline’s full-power platform. Designed around gravity-first geometry, the bike combines 181mm of rear travel (configurable down to 161mm) with a remarkably low-profile carbon frame.

What Makes the Avinox M2S Motor System a Game-Changer?

Crestline has adopted the Avinox M2S drive system as the core motor across the RS 181.2 platform:

  • Class-Leading Torque & Wattage: Delivers up to 130 Nm in standard assist modes and peaks at 150 Nm in Boost mode, outputting up to 1,500 watts of burst power.
  • High Power-to-Weight Ratio: Weighing roughly 2.6 kg (5.7 lbs), the M2S keeps overall chassis weight competitive without sacrificing high-output torque.
  • High-Capacity Power Options: Pairs with clean, integrated down-tube batteries ranging from 600Wh, 700Wh premium cell, to 800Wh, capable of rapid DC charging.
  • Cockpit Integration: Features a discrete top-tube Avinox OLED touchscreen display and minimal wireless handlebar remotes, removing cluttered wiring.
  • Intelligent Ride Tuning: Features customizable assist parameters via mobile app, alongside dynamic Auto and Boost modes that adapt torque according to cadence and trail grade.

Chassis Features & Kinematics

  • Cascade Components Suspension Linkage: Virtual pivot kinematics designed to remain supple over chatter while resisting bottom-outs under harsh compressions.
  • Wheel Configurations: Accommodates pure 29" setups or Mixed (MX 29" front / 27.5" rear) formats with adjustable chainstay lengths (435mm to 460mm depending on flip-chip and dropouts).
  • Straight 56mm Head Tube: Allows riders to use angle or reach-adjust headsets to tune cockpit figures to local trail profiles.
  • Deep Seatpost Insertion: Straight seat tube geometry allows full drop length (150mm–240mm+ travel droppers).
