NS Bikes Define AL 170 is a big-hitting aluminium enduro bike with 180mm front and 170mm rear travelMullet wheels mix a 29in front and 27.5in rear.
Modern geometry and sizing. Excellent suspension components and tyres. Recessed cabling looks sleek but without the hassle of proper internal routing.

We selfishly made the Define 170 for the riding we most enjoy. It is perfect for big jumps and severe terrain, and it is happy on the uphills, too.

Confident feel to the rear suspension
Functional spec that’ll do the job
Niggling issues with some elements of the spec
Not the comfiest ride on really rough descents
