CEF69 platform

The frame comes first.

The CEF69 is designed as a serious carbon e-MTB platform with long-travel intent, modern geometry, and clean motor integration.

170mm

Designed around aggressive long-travel riding and enduro-focused use.

Carbon frame

Light, clean-looking, and ideal for premium custom builds.

Motor choice

M510, M560, M510RS, or M560RS depending on the ride feel you want.

Key platform highlights

UK-based stock and custom build support make the CEF69 far easier to buy than importing a frame direct and handling everything yourself.

Geometry & frame details

The CEF69 features modern enduro geometry across sizes M–L, with a long reach, slack head angle (~64–65°), and steep seat angle for a balanced, confident ride. It’s designed to stay stable at speed while remaining agile on technical terrain.

Built around a 170mm fork and 205 x 60mm shock, the frame delivers approximately 160–170mm of rear travel — ideal for aggressive trail and enduro riding.

29er or mullet-ready, depending on your final build offering.

Suspension platform

Built around a 170mm fork and 205 x 60mm rear shock setup.

Travel range

Approximately 160–170mm rear travel depending on final configuration.
