Technology Highlights
Series 2 Aluminium Frame
The Bobcat Trail features a Series 2 6061 aluminium frame with butted and hydroformed tubing. Designed for durability and comfort, the frame includes internal cable routing, a low standover design, and compatibility with modern trail components.
27.5″ or 29″ Wheels
The Bobcat Trail uses a size-specific wheel strategy to provide the best balance of fit and performance. Smaller sizes use 27.5″ wheels for agility, while larger sizes use 29″ wheels for improved speed, stability, and rollover ability.
Trail Geometry
Modern trail geometry gives the Bobcat Trail predictable handling and confidence on varied terrain. A longer reach, low standover height, slack front end, and steep seat tube angle create a comfortable climbing position and stable descending performance.
Fastback Seatstay Design
The Fastback seatstay design improves vertical compliance without reducing pedalling efficiency. It also includes rack mounts, making the Bobcat Trail suitable for longer adventures and practical trail use.
