Strida

The Strida is a folding bicycle designed by British engineer Mark Sanders in the 1980s. It is immediately recognizable by its distinctive A-frame design, triangular geometry, and use of a Kevlar-reinforced belt drive instead of a traditional bicycle chain. This unique design prioritizes portability and clean operation.

The primary purpose of the Strida is for urban commuting and multi-modal travel, where it can be easily folded and carried onto public transport or stored in small spaces. Its folding mechanism is simple, typically requiring only a few seconds to fold or unfold. When folded, the wheels align, and the pedals tuck away, creating a compact, cylindrical package that can be rolled on its rear wheel like a trolley.

Key features include a lightweight aluminum frame, minimalistic styling, and an upright riding position. The absence of a chain eliminates issues with grease and chain derailment, contributing to low maintenance. The single-speed model suits flat terrains best, though multi-speed versions have been developed for more varied landscapes. The small wheels and unique handling can feel unusual to riders accustomed to standard bicycles, but many users appreciate its practicality and distinctive appearance.

Over the years, the Strida has been produced in several iterations, with improvements to the braking systems, frame materials, and folding mechanisms. It remains a niche but well-regarded product in the folding bike market, celebrated for its innovative engineering and focus on solving the challenges of city transportation.
