About this product

The ROCKBROS SKN 20" 7-Speed Folding Bike features a chromoly steel frame and fork, providing durability for urban commuting. Equipped with 20-inch wheels, Shimano 7-speed shifting (SL-RV300 shifter, RD-TY21B derailleur), and mechanical disc brakes for reliable stopping power. It includes a rear rack, fenders, and folding pedals for enhanced utility and portability. With an aluminum alloy material for rims and a total weight not specified, it's designed for unisex adults and comes with a 3-year warranty.

Our take

This ROCKBROS SKN folding bike offers a compelling package for urban riders seeking convenience and functionality. The chromoly steel frame and fork suggest good durability, which is important for a bike that might see frequent folding and unfolding. I'm particularly impressed by the inclusion of mechanical disc brakes, providing superior stopping power compared to traditional rim brakes. The Shimano 7-speed drivetrain is a reliable choice for navigating city streets. It's great to see practical features like a rear rack, fenders, and folding pedals included. While the 'Model Year 2025' might be optimistic, the 3-year warranty is excellent value for a bike at this $279.99 price point.
