BMC Twostroke AL 24

A lightweight aluminium frame, with a premium durable powder coating and a dedicated geometry to smaller riders. Featuring 24” wheels, an 8-speed SRAM groupset and TEKTRO brakes, with tailored ergonomics for a confidence inspired ride. Simple. Functional. Fun.

Lightweight Frame
Double butted tubes for a lightweight 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 our MTB’s and 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: simply clever. A thin layer of gloss paint adds a premium finishing touch.

Control and Safety
Hydraulic brakes and high-volume tires provide control and safety on various surfaces with low rolling resistance.
