Installing Removable Bike Bollards using Concrete Inserts in Existing Concrete

Home > How to Install Commercial Bicycle Racks and Bike Bollards > Installing Removable Bike Bollards using Concrete Inserts in Existing Concrete

Reliance Foundry’s bike bollards can be made removable with removable mounts using drop-in concrete inserts. This mounting system allows bike bollards to be removed by simply unfastening a padlock and removing a pin that runs through the center of the bike bollard’s base.

Removable bike bollards combine the convenience of access control with reliable bike storage. It is important to note that with this installation method, bike bollards offer limited impact resistance.

Bike Bollard Cap



Drop-In Concrete Insert 3/4″



Removable Mount 1″



Washer 3/4″



Hex Bolt 3/4″



Hexagon Socket Set Screw



Plastic Plug



Lock Pin



Padlock (optional)




Dirt Tamper


3/16″ Hex Key


Measuring Tape

1-1/2″ Wrench


Before installation

Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before digging.

Clean the surface
Dirt and debris can affect the line of sight and disrupt placement of the bike bollards.

Use a broom or pressure washer to clean the concrete surface prior to bike bollard installation.

Study the site plans
Site plans are generally created by the architect of the project.

Refer to site plans to locate and mark the precise center point of each bike bollard.

For secure installation, ensure there is a minimum radius(1) of solid concrete around each mark.

Drill the hole

Create pilot hole
Tap a pilot divot hole in the center of each mark.

This will prevent the hammer drill or rotary hammer from drifting while boring the hole.

Set the depth control on the hammer drill (or rotary hammer) to 3-1/8″
If depth control is not available, mark 3-1/8″ on the masonry bit.

Drill the hole
Drill a hole that has a 1″ diameter and 3-1/8″ depth.

Drill on high speed, using the hammer function if available.

Check the masonry bit often to ensure it remains free of debris.

Secure the bollard

Clear the hole
Clear the hole of all debris and/or standing water using the vacuum.

Tap the drop-in insert into the hole and set concrete insert
With the slotted end facing down, drive the drop-in insert (A) down until its top sits flush with the concrete surface. Ensure that the top is perfectly level.

Insert a setting tool (B) into the threaded hole, then hammer down.

If a proper setting tool is not available, an equivalent flat-end punch can be used.

This will cause the internal expansion plug to set the concrete insert in place.

Secure the removable mount
Place the mount on top of the concrete insert so that the center holes line up. Place the washer over the top of the center hole. Insert the 3/4″ bolt and use a wrench to tighten until the mount is secure.

Note: Be sure to check the orientation of the bike bollard arms before securing the bike bollard.

Set the bike bollard over the removable mount
Keep the bike bollard in its protective packaging. When ready to install, remove the bike bollard’s protective packaging.

Set the bike bollard base upright and place over the mount. Ensure that the bike bollard base is centered over the mount.

Insert the lock pin
Insert the lock pin through the holes of the bike bollard base. Twist the bike bollard in a clockwise motion to secure into position. Fasten the padlock.

Secure the bike bollard cap
Remove bike bollard cap from its packaging.

Place the cap on the top of the shaft of the bike bollard.

Secure and align the cap to the bike bollard base with the three set screws. Tighten in equal amounts to ensure that the cap remains centered.

Place the plastic plugs (C) over the set screws.

Note: The bike bollard cap can remain intact when replacing or removing bike bollards in the future.


Inspect the installation
From a distance, examine the plane of view.

Ensure the bike bollard is plumb to the surface, and the surface is flat.

Check the bike bollard for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bike bollard. For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.

Care and maintenance

Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance Foundry’s bike bollards are finished with long-lasting powder coating. In most North American environments, routine inspections and cleaning will ensure that bike bollards retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.

1. Concrete insert manufacturers such as www.ucanfast.com recommend an anchor spacing of 7-1/2″, and a minimum edge distance of 9″ for 100% performance.
