Frequently Asked Questions

What makes the K5 classification significant for a wheelchair?
The K5 classification refers to a category of ultra-lightweight wheelchairs that meet specific weight and performance criteria. K5 chairs are generally the lightest and most performance-oriented category of manual wheelchairs, designed for users who are highly active or who require a chair that can be easily self-propelled or transported. The lightweight aluminum frame and performance features of the Lynx K5 — including quick-release axles, dual axle positions, and precision-sealed bearings — reflect the higher-performance standard associated with this classification.

How do the quick-release axles work?
Quick-release axles allow the rear wheels to be removed without tools by pressing a button or lever at the center of the axle hub. This makes it significantly faster and easier to disassemble the chair for loading into a vehicle, storing in a compact space, or performing maintenance. When reattaching the wheels, the axle clicks back into place and locks securely. Always confirm the axle is fully locked before use after reattaching the wheels.

What is the difference between desk arms and full-length arms?
Desk arms are shorter than full-length arms and are cut away at the front, allowing the user to roll closer to a table, desk, or counter without the armrest getting in the way. The flip-back design on the Lynx K5 allows the arms to fold back out of the way entirely, which is particularly useful during side transfers — moving from the wheelchair to a bed, car seat, or chair — where a fixed armrest would create an obstacle.

Are the elevating leg rests included or optional?
Elevating leg rests are included with this configuration of the Lynx K5. They allow the lower legs to be raised to a more horizontal position, which can improve comfort during extended sitting, support circulation, and accommodate users who cannot maintain a standard 90-degree knee position. The leg rests are adjustable in elevation angle and can be swung away or removed for transfers and compact storage.
