Product Details

Whyte 603 2020 - Hardtail Trail MTB

Whyte’s design team have given the latest 600 series frame the Trail treatment. A 120mm fork, wider 760mm bar, shorter stem, wider grippier tyres and even our Enduro developed V-grips, makes the Whyte 603 the most trail-ready bikes in this price category. 

You’ll find it hard to believe the 603 is Whyte’s entry level mountain bike: with carefully chosen, branded parts and a high quality, latest generation frame it has all the hallmarks of Whyte’s award winning DNA.

Key Features

  • Whyte progressive geometry with 68.5 degree head tube angle, short stem and wide bars deliver confidence-inspiring control - the key to enjoying mountain biking.
  • Whyte 6061 hydroformed frame with custom tubing for lightest weight in its class
  • The frame is made especially clean with Whyte's BBX (bottom bracket exit) internal cable routing, which is weather sealed, dropper-seat ready, and designed to facilitate easier cable replacement in years to come
  • Tektro HD-275 brakes - given how many great bikes come with these stoppers, Tektro are probably the best proven hydraulic disc brakes in mountain biking today. Why you want hydraulic disc brakes
  • Smooth-shifting Shimano Altus 2x9 drivetrain offers a massive range of gears to cover any ridable terrain
  • WTB Trail Boss Comp 27.5” x 2.25” Front, WTB Ranger Comp 27.5” x 2.25” Rear
  • The short (35 or 40mm depending on frame size) stem with 760mm (740mm on smaller 603 sizes)wide bars with Whyte Lock-on V Grip put you in control

The latest frame bristles with UK design features such as the “Get A Grip” seat post clamp system. This allows quick adjustment, fantastic weather proofing and a nice ergonomic lever which is easy to operate however cold your hands might be.
