Key Features

  • Light-weight construction combined with high-air volume tyres give a high quality ride with less trail chatter
  • Powerful hydraulic brakes provide plenty of easy stopping power
  •  Hydroformed alloy frame made for an SCR (single chain ring) transmission, and optimised for UK riding conditions
  • Sram X4 transmission delivers a superb range of gears in a simplified 1x8 format via its 11-34 cassette and 28t single chainring (no double shifting required)
  • Stopping power is equally impressive, thanks to the Whyte 303's Tektro M-275 hydraulic disc brakes with short reach leavers
  • Compared with a normal 20 inch wheel bike for younger riders, the Whyte 303's Schwalbe Smart Sam 24x2.35 tyres offers significantly improved traction, rollover and speed potential.
