Rack guidance comes from APBP's 2015 Essentials of Bike Parking. APBP published a 3rd edition of its full Bicycle Parking Guidelines in 2026, which sits behind a paywall and was not checked here. City numbers vary, so each one is labeled with the city that uses it. Bike drawings follow manufacturer overall dimensions; tube layouts are simplified.
