Product Description
Take on everyday mobility with these RIANT RX16 25" (559mm) 16 Spoke Aluminum Rear Wheels, featuring Kenda Kobra 25" x 2" Pneumatic Tires and black anodized aluminum handrims. Designed for strength, durability, and responsive rolling performance, these wheels combine lightweight double-wall aluminum rims with a specialized spoke configuration to support a variety of wheelchair activities.
Each wheel features eight 12-gauge straight-pull spokes on the inside of the hub and eight cross-laced J-bend spokes on the outside. The straight-pull spokes help improve side-load integrity when cambering the wheels, while the cross-laced spokes support rotational strength. Equipped with 1/2" sealed precision bearings, high-strength aluminum hubs, and 6-tab aluminum handrims, these assemblies provide a complete rear wheel replacement for compatible manual wheelchairs.
The Kenda Kobra 25" x 2" pneumatic tires feature a wide, air-filled design. Their 2" tire width requires careful consideration of wheelchair frame clearance, particularly when upgrading from narrower 1" or 1-3/8" tires. Choose between black or silver hub finishes to customize your wheel configuration.
✅ Compatibility
• Invacare Wheelchairs, including compatible Top End models.
• TiLite Wheelchairs.
• Quickie Wheelchairs.
• Colours Wheelchairs.
• Other manual wheelchairs requiring 25" (559mm) rear wheels with 1/2" inner diameter bearings.
• Hub Width: Confirm the bearing-to-bearing measurement before ordering due to conflicting measurements in the original product information.
• Tire Width: 2" — longer axles and additional spacers may be required for sufficient wheelchair frame clearance.
• Verify your existing wheel size, axle diameter, hub width, axle length, and tire clearance before ordering.
Axle Compatibility and Measurement
The Kenda Kobra 2" wide tires may require additional clearance when replacing narrower wheelchair tires. If your wheelchair currently uses 1" or 1-3/8" tires, you may need longer axles and spacers to position the rear wheels farther away from the wheelchair frame.
The original fitment guidance indicates that axles approximately 1/2" to 3/4" longer may be needed, depending on your wheelchair configuration.
To determine whether your existing axle is compatible, add the wheel's confirmed bearing-to-bearing hub width to the width of your wheelchair's axle carrier tube and any spacers being used. Compare this total with the usable length of your existing axle.
• Quick-Release Axles: Measure from the underside of the adjustment nut to the beginning of the retractable locking ball. Many quick-release axles allow up to approximately 1/4" of length adjustment.
• Conventional Hex-Head Axles: Measure from the underside of the axle head to the end of the axle, allowing additional length for the retaining nut.
• Wheel Spacers: Compatible spacers may be required to prevent the wider tires from contacting the wheelchair frame.
Features
• Kenda Kobra Pneumatic Tires: Wide 25" x 2" air-filled tires for compatible wheelchair applications.
• 16-Spoke Configuration: Combines eight straight-pull spokes with eight cross-laced J-bend spokes.
• 12-Gauge Spokes: Heavy-duty spoke construction provides strength while reducing the overall spoke count.
• Straight-Pull Inner Spokes: Help improve side-load integrity when cambering the wheels.
• Cross-Laced Outer Spokes: Support rotational integrity and wheel stiffness.
• Double-Wall Aluminum Rims: Lightweight, high-strength construction with an 18mm internal rim width.
• Aluminum Wheel Hubs: High-strength construction with black or silver finish options.
• 1/2" Sealed Precision Bearings: Designed for compatible wheelchair axle configurations.
• Black Anodized Aluminum Handrims: Standard 6-tab mounting design with two-hole adjustment.
• Complete Rear Wheel Assemblies: Supplied with the selected tire configuration and black aluminum handrims.

Important Tire Clearance Information
The Kenda Kobra tires are 2" wide. If your wheelchair currently uses narrower 1" or 1-3/8" tires, longer quick-release axles and additional wheel spacers may be necessary to prevent the tires from rubbing against the wheelchair frame.
The original fitment guidance suggests axles approximately 1/2" to 3/4" longer for certain configurations.
Check your existing axle length, wheel spacing, bearing diameter, and frame clearance before ordering.
