BUILD YOUR RS 181.2

THE CRESTLINE RS 181.2

BUILT FOR THE STEEP STUFF

The RS 181.2 is Crestline's answer for riders who want downhill-bike capability without waiting for the next shuttle. With 181mm of high-pivot rear travel, a DH-rated carbon chassis, and the compact Avinox drive system, it's built to take on the steep, rough terrain you'd normally save for a DH bike, then power you right back to the top.

And it isn't a one-trick pony. Adjustable geometry, multiple wheel configurations, and a highly tunable suspension platform let you set up the RS 181.2 around how and where you ride.

RS 181.2

Carbon Material
29 | MX Wheel Size
161 | 181 Rear (MM)
160-200 Front (MM)
700 | 800 Battery (WH)
150 Max Torque (Nm)

REMOVABLE BATTERY

Bolted securely into the frame for a solid, quiet connection, the Avinox battery can still be easily removed without pulling the motor. Swap batteries for hot laps, simplify travel, or pull it when needed for charging and service.

AVINOX M2S

FULL POWER. LESS BULK.

The Avinox M2S delivers full-power eMTB performance from an impressively compact drive unit. The RS 181.2 has the power for steep climbs and quick self-shuttle laps without the bulk you'd expect from a full-power system.
130 Nm Max Continuous Torque
1,500 W Peak Power
2.52 kg Weight
≤ 45 dba Sound Pressure Level

POWER OR RANGE

700WH OR 800WH

Choose the 700Wh battery for maximum power and a lighter setup, or the 800Wh battery for increased range. Both can be removed from the RS 181.2 without pulling the motor, making charging, travel, and battery swaps easy.
