Safety, gear, and traffic rules: how to ride without a hospital trip or a fine
Real injury data (Austin Public Health: ~20 injuries / 100,000 trips, 48% head injuries, 1 in 190 helmeted; UCLA JAMA: 40.2% head; CDC Austin MMWR: 33% in first two rides, 48% alcohol-involved). Helmets: when EN 1078 / CPSC is enough, and when you need NTA 8776 or a DOT FMVSS 218 motorcycle helmet. Gloves, body armour, visibility. Specific traffic rules: Ukraine PLET (Law No. 2956-IX, 16+, 25 km/h), Germany eKFV (14+, Versicherungsplakette insurance plate, 0.5 ‰), UK trials (Category Q, rentals only, 15.5 mph, helmet recommended), US — fragmented across 50 states. Pre-ride check, behaviour on cycle paths/roads/sidewalks, the seven anti-patterns that systematically end in ER visits.
