The Focus Whistler 3.8 29" Hardtail Mountain Bike has reliable Shimano Deore gears with a 10-speed cassette and double chainset, so you shouldn't be left wanting more on steep climbs.

The 29" wheels are fast rolling and help to smooth out the trail whilst the SR Suntour suspension absorbs the bigger impacts. Hydraulic disc brakes give you confidence in all conditions and there are mounts for attaching racks or mudguards.

Focus Whistler 3.8 29" Hardtail Mountain Bike 2020

The lightweight aluminium frame and reliable Shimano Deore components help the Focus Whistler 3.8 29" Hardtail Mountain Bike to make short work of hills so that you can build your confidence with off-road riding. Grippy Smart Sam tyres with tan sidewalls are a great look and the 29" rims carry momentum over bumpy trails and combine perfectly with the SR Suntour suspension fork to deliver a comfortable and smooth ride. You can mount mudguards for riding in winter or racking should you wish to carry more gear and set off on longer adventures over mixed terrain.


  • Shimano Deore 10-speed cassette with 2X drivetrain
  • Tan sidewalls tyres look great
  • Shimano hydraulic disc brakes ensure that your stopping power won't be compromised come rain or shine
  • Grippy Schwalbe Smart Sam tyres
