360-Degree Adjustable Cycle Mirror

Exact footprint: 15.5 cm length × 13 cm width × 10 cm depth (6.10 × 5.12 × 3.94 in). Total assembled weight approximately 180 g — light enough not to affect steering balance yet substantial enough to resist wind flutter. Constructed using injection-moulded ABS for shell integrity and precision-extruded aluminium for load-bearing arms. Intended for handlebars 20–24 mm — confirmed working fit on Brompton, Riese & Müller, and Invacare trikes. Mounting relies on a two-bolt clamping system with integrated rubber buffers — tested to retain position under sustained vibration (ISO 5008 simulation). Mirror glass is shatter-resistant acrylic with scratch-resistant coating — safe for public use and compliant with general EN 14766 guidance for cycle accessories. The 360-degree capability is achieved via dual stainless steel pivot pins — smooth operation retained after >5,000 rotation cycles in lab testing. Commonly adopted by cycle training providers, occupational therapists prescribing assistive devices, and councils installing shared-use path infrastructure — where repeatability of fit, longevity under communal use and tactile ease of adjustment are non-negotiable requirements.
