The BMC Twostroke AL 20 Kids Bike features a lightweight aluminium frame, with a premium durable powder coating and a dedicated geometry for smaller riders. Featuring 20” wheels, an 8-speed SRAM groupset, TEKTRO hydraulic disc brakes, 2.4" Kenda MTB tyres, and an SDG cockpit and saddle, with tailored ergonomics for a confidence-inspired ride. It may be 'just' a kids' bike, but the BMC Twostroke AL 20 doesn't skimp on quality. The BMC Twostroke AL 20 Kids Bike uses 20" wheels, suitable for riders ranging from 110-135cm tall, or around 5-8 years old. 

Features

  • Lightweight Frame: Double-butted tubes for a lightweight, nimble frame with a distinctive and premium look.
  • Tailored Ergonomics: Bars, levers, cranks and saddle are tailored for the ergonomics of young riders for a comfortable and custom-made ride.
  • Dedicated Geometry: Inspired by BMC's premium XC and Trail mountain bikes, just adapted to smaller riders for intuitive and reliable riding.
  • Powder Coat Finish: Powder coating is highly resistant to wear and reduces the impact on the environment with excess powder being reused rather than wasted. A thin layer of gloss paint adds a premium finishing touch.
  • Control and Safety: Hydraulic disc brakes and high-volume tyres provide control and safety on various surfaces with low rolling resistance. You can really feel the MTB influence!
