Liberty Trike 31-Inch Axle Replacement Kit (For 16-Inch Models)

$ 38.00

| /

Upgrade your 16-inch Liberty Trike for increased stability and peace of mind.
This 31-inch rear axle replacement kit widens the rear frame by 5 inches (from the original 26" axle to the new 31"), giving you a sturdier, more secure ride — especially helpful on turns and uneven terrain.

All customers purchasing this kit will receive the latest 31-inch axle version, which includes updated hardware designed to keep the axle properly centered once installed.

Compatible with all 16-inch Liberty Trike models ever made
⚠️ Not needed for 20-inch models — they already include a wider rear axle


What’s Included:

  • 1× 31-inch rear axle
  • 2× axle spacers (for the frame)
  • 2× axle nuts
  • 2× axle keys (center + drive side)
  • 2× axle washers
  • 2× axle centering couplers (new – helps lock the axle in position once installed)

Note: Some of the small hardware components such as the centering couplers may not appear in older product photos, but they are included with the current 31-inch axle kit.


Installation Guidance:
We've created a step-by-step instructional video (shown below) that demonstrates the general installation process.

The video provides a helpful overview of the procedure, although the latest kit includes the updated 31-inch axle and centering couplers which may not appear exactly the same as earlier versions shown.

If you're comfortable with basic mechanical tools, you may be able to install this yourself by following the video carefully.

If you're not mechanically inclined, we strongly recommend taking the trike (rear half only) to a local bike shop.

You don’t need to bring the battery or basket — just the rear frame section.

Additional photos on this page show the final axle placement and coupler installation so you can see exactly how the updated kit fits once installed.

Taking a few minutes to call your local shop in advance and confirm they'll do the install can save time and hassle. This is a simple but important upgrade — and whether you DIY or go pro, this kit will make your trike even better.
