79BIKE Falcon GT Rear Axle Replacement Guide (15mm Rear Wheel Axle)

If you ride a 79BIKE Falcon GT, your rear axle is one of the most important — and most overlooked — components on the bike. The rear axle holds everything in alignment: your wheel, chain, brake rotor, and swingarm. When it bends, wears, or loosens, the entire bike suffers.

This guide breaks down everything you need to know about the Falcon GT rear axle replacement, including why the 15mm rear axle matters, common failure signs, and how replacing it can instantly improve ride quality and safety.

Why the Rear Axle Matters on the Falcon GT

The Falcon GT produces serious torque compared to traditional pit bikes or bicycles. That torque transfers directly through the rear wheel and axle. Over time, hard acceleration, landings, wheel removals, or chain tension issues can cause:

• Bent or worn rear axles

• Wheel misalignment

• Chain tracking problems

• Premature bearing failure

• Unsafe handling at speed

A compromised axle doesn’t always fail catastrophically — often it causes subtle problems that slowly get worse.

Falcon GT Rear Axle Specs (What You Need to Know)

Most 79BIKE Falcon GT models use a 15mm rear wheel axle, which is common across high-performance electric dirt bikes.

Key specs to verify before ordering:

• Axle diameter: 15mm

• Overall length: Varies by setup (measure your stock axle)

• Material: High-strength steel recommended

• Thread condition: Must clamp securely without stretching

Always measure your original axle end-to-end to confirm length, especially if running aftermarket wheels or spacers.

Signs You Need a Rear Axle Replacement

If you notice any of the following, it’s time to replace your Falcon GT rear axle:

• Rear wheel doesn’t stay centered

• Chain constantly needs adjustment

• Clicking or creaking from the rear end

• Uneven brake rotor alignment

• Axle nuts won’t hold torque

• Visible bend or wear marks

Replacing the axle early can prevent damage to your swingarm, bearings, and wheel hub.

Benefits of a High-Quality 15mm Rear Axle

Upgrading or replacing your rear axle restores the bike’s foundation. A proper Falcon GT rear axle replacement offers:

• Solid wheel alignment

• Smoother drivetrain operation

• Reduced bearing and chain wear

• Improved braking consistency

• Increased safety at speed

It’s a small part that makes a massive difference.

Installation Tips

• Support the bike securely before removal

• Loosen chain tension evenly

• Inspect spacers and bearings while the axle is out

• Torque axle nuts evenly to spec

• Recheck alignment after your first ride

A fresh axle paired with properly adjusted chain tension will make the bike feel tighter immediately.
