Bicycle Racks

Best Practices

Good Bicycle Racks
  • At least 18” wide and 33” tall when installed
  • Securely anchor to a solid, immovable surface
  • Provide two points of contact for typical adult or child’s bicycle frame
  • Allow user to lock frame and one wheel using standard U-lock
  • Constructed of steel pipe or tubing
  • Galvanized with a powder coat finish to protect against corrosion (outdoor racks)
Photo: Inverted U racks, installed
Inverted-U racks are a common choice.

Commonly Accepted Rack Types
  • Inverted-U or hoop rack
  • Circular or ring rack
  • Vertical racks (indoor only)
  • Double decker racks (indoor only)

Layout and Installation

Sidewalk Installation

In-Ground Mount (Preferred Method)

In Brick or Stone Pavers

  • Legs must be 9” deep in a 12” x 12” concrete block
  • Block must be under 6” of pavers

In Concrete

  • Tubes must be minimum 9” deep in concrete

Diagram: U rack in-ground installation Photo: U rack in-ground installation

Surface Mounted Racks
  • Minimum of two fasteners per mounting plate
  • Concrete pad must be 4” deep
  • Use tamperproof studs or anchors

Diagram: U rack surface installation Photo: U rack surface installation

Installing on a Slope
  • Always ensure that the legs of the rack are vertical
  • Preferred method is using in-ground racks
  • For surface mounted racks, the use of shims may accomplish this task
Photo: In-ground U racks installed correctly on a slope
These inverted-U racks were installed with one leg deeper than another, with the result being an even installation on a slope.
Photo: Surface-mounted U-racks installed incorrectly on a slope
These inverted-U racks were surface mounted on a slope with no shims, and the installation is tilted.
Hardware
  • Exposed threads/nuts should be stainless and not galvanized

Acceptable Hardware

  • Concrete spike
  • Security nuts
  • Threaded expansion anchor or Rawl stud
  • Metal shims

Retail 2 spaces for every 10,000 sf, up to 50,000 sf, then 1 space for each additional 12,500 sf
Hotel 1 space for every 50 units
Educational 1 space for every 10 High School students, 15 Middle School students, and 20 Elementary School students

Note: These ratios are the most current. Please verify for your project in the site plan conditions.

Pros: Clean, discrete, highly secure, less conflict with cars

Cons: May take up leasable square footage

Photo: Class I Parking Location Best Option

Second Best Option

Fully enclosed room in garage

Pros: Discrete, highly secure

Cons: Conflicts with cars, can be uninviting

Photo: Class I Parking Location Second Best Option

Third Best Option

Cage in a garage

Pros: Secure

Cons: Bikes are visible to potential thieves, conflicts with cars, can be uninviting

Photo: Class I Parking location third best option

Special Scenarios

Bike Lockers

Pros: Secure, protection from weather (for bicyle)

Cons: Bicyclist not protected from weather, not space efficient

Photo: Class I Parking Special Scenario -- lockers

Additional Requirements

Architectural and Civil Plans

For each type of bicycle rack, provide a construction specification sheet with
information from the manufacturer, and hardware schedule. Where needed for clarity,
there should be drawings depicting ceiling clearance above the racks.

Practices to Avoid

Common Mistakes

Bad Bicycle Racks
  • Require excess lifting
  • Have unintuitive design (the simpler the better)
  • Too narrow to support wheel and frame (18” minimum)
  • Easily dislodge from the ground (remember tamperproof hardware)
  • Constructed of materials that will rust and corrode
  • Create conflict with the handlebars

This rack is not functional due to its proximity to obstructions.
Photo: Sculptural bike rack
Artistic racks can have designs that are confusing to cyclists.
Unacceptable Rack Types
  • Wave racks
  • Fence racks
  • Spiral or corkscrew racks
  • Coat hanger racks
  • Wheel block racks
