Origin

The Define launched in January 2019 as NS Bikes' statement that a Polish brand could play at the top of the full-suspension market. The carbon platform was designed in-house with a clever modular approach: swapping the rear shock mount converts the frame between trail (130mm) and enduro (150mm) configurations, letting riders own one frame for two disciplines.

Specifications

Frame: Carbon front triangle and rear linkage; aluminium rocker link. Available in AL version too (Define AL 160/170)
Drivetrain: SRAM X01 Eagle 12-speed (top builds); lower builds use SRAM NX/GX Eagle
Brakes: SRAM Guide RS hydraulic disc; 200mm front / 180mm rear (150 builds)
Wheels: 29" exclusively; tubeless-ready

The verdict

+Strengths

Modular travel (130mm/150mm) gives genuine two-in-one versatility from a single frame
Slack 64.5° head angle and long reach deliver confident descending at speed
Carbon construction keeps weight competitive with European enduro brands

−Weaknesses

Chainstay length (440mm) is relatively long — less agile in tight technical sections
Swapping shock mounts to change travel requires workshop time and two shocks
Entry-level Define AL builds are heavier and lose the carbon efficiency benefit
