How to Install 24-Inch Rear Wheels & Handbrakes

Every child has unique mobility needs, and those needs often evolve over time. One of Cub's greatest strengths is its modular design, allowing the wheelchair to grow and adapt as users become more active and independent.

One popular upgrade is replacing the standard 16-inch rear wheels with the optional 24-inch rear wheels equipped with push rims and handbrakes. This configuration allows older children and teenagers to self-propel more efficiently while giving caregivers additional braking control when needed.

In the video below, we demonstrate how to install the 24-inch rear wheel upgrade and handbrakes.

Why Upgrade to 24-Inch Rear Wheels?

As children grow, many develop the strength and coordination to propel their own wheelchair. Larger rear wheels provide a more efficient pushing position and improve independence in everyday mobility.

The 24-inch wheel upgrade offers several important advantages:

• Allows independent propulsion using push rims.

• Improves rolling efficiency over longer distances.

• Supports growing children and teenagers.

• Provides caregivers with integrated handbrakes for greater control on slopes and uneven terrain.

• Expands Cub's adaptability without replacing the wheelchair.

This flexibility helps maximize the useful life of the wheelchair while supporting changing clinical and functional needs.

Installation Overview

Installing the 24-inch rear wheel kit is a straightforward process demonstrated in the accompanying video.

The installation includes:

1. Removing the standard rear wheels.

2. Installing the axle receivers.

3. Mounting the 24-inch quick-release wheels.

4. Installing and adjusting the caregiver handbrakes.

5. Verifying proper wheel alignment and brake operation.

Always confirm that both wheels are securely locked before using the wheelchair.

Designed for Growth and Independence

Cub was designed with exceptional growth adjustability, allowing it to support users from early intervention through adolescence.

The optional 24-inch rear wheel kit transforms Cub from a caregiver-propelled configuration into a wheelchair that can also support independent mobility, depending on the user's abilities.

Because the conversion uses quick-release axles, the wheels can be removed easily for transportation or maintenance.

Safety Tips After Installation

After installing the upgrade kit, always:

• Verify that each quick-release axle is fully engaged.

• Test both handbrakes before placing the user in the wheelchair.

• Ensure the wheel locks continue to function properly.

• Confirm that tire pressure is correct if using pneumatic wheels.

• Perform a short test drive before regular use.

Proper installation and adjustment improve both safety and performance.

Frequently Asked Questions

Why choose 24-inch wheels instead of 16-inch wheels?

Larger wheels allow many users to self-propel more efficiently and comfortably using push rims.

Can the wheelchair still be folded?

Yes. Cub maintains its transport-friendly folding design after the upgrade.

Are the wheels removable?

Yes. The 24-inch wheels use quick-release axles, allowing them to be removed quickly for transport or maintenance.

Do all users need this upgrade?

No. The standard 16-inch wheels are ideal for many younger children and caregiver-propelled use. The 24-inch upgrade is intended for users who can benefit from greater independence or require larger wheels for their mobility goals.

A Wheelchair That Grows with the User

One of Cub's defining features is its ability to adapt over time. Rather than replacing the wheelchair as a child grows, many components—including rear wheels, seating adjustments, and positioning supports—can be upgraded to match changing clinical and functional needs.

This modular approach helps families, therapists, and equipment providers maximize the value and longevity of the wheelchair while continuing to provide appropriate postural support and mobility.
