How To Check Your Axle Size At Home:

1. Measure The Axle Diameter

Use a digital caliper or ruler to measure across the threaded axle:

• Approximately 12mm outside diameter = M12 axle

2. Verify The Thread Pitch

An M12 x 1.25mm axle means:

• 12mm axle diameter

• 1.25mm spacing between threads

You can check this by:

• Using a thread pitch gauge

• Comparing against another known M12x1.25 bolt

• Visiting a local hardware store for thread matching

3. Check Existing Hardware

Some original axle nuts may have markings stamped on them indicating the size or thread pitch.

4. Review Your Owner’s Manual

Many eBike manufacturers include axle specifications in the technical or wheel section of the manual.

Common Signs You Need Replacement Axle Nuts:

• Rounded or stripped threads

• Loose rear wheel

• Missing hardware

• Damaged or rusted nuts

• Wheel shifting inside the dropout
