BMC Twostroke AL SIX 29" Mountain Bike 2022

A light, responsive and strong Premium grade aluminium frame unites with a SUNTOUR XCM suspension fork to make the BMC Twostroke AL SIX 29" Mountain Bike a lively, composed and accurate ride over any XC-style trails and tracks. The frame and fork are complemented by robust 29” wheels that seemingly roll through obstacles, and high-volume WTB tyres increase traction on steep climbs and in fast corners.

An aggressive geometry positions the rider with perfect balance, allowing them to attack technical ascents and loose surfaces. The Shimano Deore 1 x 10-speed gear configuration offers a wide range of ratios so that any topography can be tackled with success, while the hydraulic disc brakes, also from Shimano, afford accurate and reliable stopping power in all conditions.


  • A versatile, agile and confidence-inspiring hardtail suitable for all XC style trails
  • Premium hydroformed aluminium frame with smooth welds is light and reactive
  • The frame offers clearance for up to 58mm wide tyres
  • Internal cable routing keeps the aesthetics clean and crisp
  • Moulded covers on the chainstay, a chain suck plate and helicopter tape on the downtube protects the frame
  • A SUNTOUR XCM 32 fork cushions the trails and increases control with its plush suspension
  • A 67˚ head angle, long front-end and 75° seat angle helps the rider attack steep and loose terrain with perfect weight distribution
  • Strong, reliable 29” wheels and wide, grippy WTB tyres tame any trail
  • Shimano Deore 1 x 10-speed gears are accurate and give a huge range of ratios for any terrain
  • Shimano hydraulic disc brakes are precise and powerful
