NS Bikes Define AL 150 1 Trail Mountain Bike, Black/Blue

The Define AL 150 1 is a 29er that can pedal up the climbs others walk and fly down the sections others plough through. Fox Performance suspension at both ends gives you 160mm up front and 150mm out back.

The hydroformed aluminium frame has adjustable bottom bracket height, semi-internal cable routing that's easy to service, and big sealed main pivot bearings for long, low-maintenance life.

We're an authorised NS Bikes dealer working directly with the official UK distributor. That lets us offer brand-new, boxed bikes with full manufacturer warranty at a sharper price than you'll usually see.

Delivery and build

Ships brand new in its original box, direct from the UK NS Bikes distributor. It arrives part-assembled: you'll need to fit the handlebar, front wheel and pedals, then set up the suspension and check the brakes and gears. If you'd rather it was built by a mechanic, get in touch before ordering.
