Meets APBP Guidelines: Racks fully adhere to the guidelines for bike parking as written by the Association of Pedestrian and Bicycle Professionals.
Bike Friendly Containment: The rack captures the bikes tires in a well or cradle in such a way so that there is no wheel bending, yet the bike is secured enough to not slide or slip from its upright position.
Simple & Intuitive: Simple and intuitive racks exhibit few options for a cyclist to lock their bike. They offer minimal parking methods (front and back only) and minimize the possibility of securing a bike in an incorrect way that will cause unorganized or non-secure bike parking.
Security: The rack should be equipped with a feature (such as an arm or wing) to allow the bicycle to be locked to the rack with an external lock and a closed part of the bicycle frame, as well as offer the ability to lock the wheel, frame, and rack in unison.
Density: How well the rack contains and organizes large numbers of bikes in different configurations and locations while still keeping parking organized to allow cyclists sufficient access to their bikes.
Cost Per Bike: The approximate dollar amount an individual rack will cost in respect to how many bikes it will hold.
Cost Per Bike+Shipping: The approximate dollar amount an individual rack will cost in respect to how many bikes it will hold plus the cost of freight. Because different racks weigh more or less, and ship to and from different locations, the cost of freight varies and therefore can make a total purchase price more or less expensive than just averaging the cost per bike.
