Description
We got our hands on a limited batch of Crestline RS 181.2 frames and built the Fanatik complete we'd want to ride ourselves.
The RS 181.2 Factory Spec is built around premium FOX Factory suspension, with a FOX 38 Factory up front and Float X2 handling the rear. SRAM X0 Eagle Transmission delivers crisp, reliable shifting when the trail gets rough, while Reserve 30 HD Carbon MX wheels keep the build light, stiff, and ready for hard riding. SRAM Maven Ultimate brakes provide the stopping power to match, and a Transfer Neo wireless dropper rounds out the build.
Premium components where they matter, chosen for a bike that's meant to be ridden hard.
The Crestline RS 181.2 is the latest evolution of Crestline's AVINOX-powered eMTB platform, combining serious power with a refined, gravity-focused chassis. Crestline reworked the frame to reduce weight and bulk around the bottom bracket while maintaining a CAT 5 DH strength rating, resulting in a quieter, more streamlined platform built to take full advantage of the DJI Avinox drive system.
The RS 181.2 pairs Avinox power with adjustable geometry, 29" or mixed-wheel compatibility, multiple chainstay configurations, and adjustable rear travel between 161mm and 181mm. A 56mm head tube allows for reach adjustment, while generous tire clearance and dual-crown compatibility make it easy to tailor the bike for everything from technical trail riding to full-on gravity use. The removable Avinox battery also makes charging, travel, and battery swaps straightforward.
