Description
The TMS Silex V4 24” is the latest evolution of TMS’s iconic street-trials bike — proudly designed and engineered in France. Built from high-quality chromoly steel, the Silex V4 delivers exceptional ride feel, combining strength, comfort, and precision across all terrains — from street to skatepark, pump track, or natural lines.
Its steel frame absorbs surface imperfections for a smoother, more fluid ride, while allowing thinner tubes for reduced weight and a clean, refined aesthetic. The striking Deep Blue clearcoat reveals the raw steel tones beneath, creating a unique “tattooed metal” finish designed by rider Yann Dunant.
Offering an unbeatable balance of quality, performance, and style, the Silex V4 stands out as one of the most versatile and best-value street-trial bikes on the market.
