If you own a Segway Xyber, you might have noticed that the rear suspension can sometimes be less supportive than desired, especially for heavier riders. Many users in Segway forums report issues like bottoming out, which affects ride comfort and control. Fortunately, upgrading the rear shock is a practical solution to enhance your Segway’s performance. In this detailed guide, we’ll walk you through the entire process of upgrading your Segway Xyber’s rear shock, including the necessary tools, parts, and installation tips.

Common Issues with Stock Suspension

The stock rear shock on the Segway Xyber offers substantial travel and cushioning, but it may not be sufficient for all riders. Many users experience the shock bottoming out during rides, which means the suspension compresses fully and loses its ability to absorb bumps. This can lead to an uncomfortable ride, increased stress on the frame, and potential damage over time.

Benefits of a Rear Shock Upgrade

Upgrading to a higher-quality rear shock with a stronger spring can significantly improve ride stability and comfort, especially for riders who weigh more or frequently ride on rough terrain. A better shock reduces the likelihood of bottoming out, improves handling, and extends the lifespan of your Segway.

Recommended Shock Model

The most popular upgrade among Segway Xyber users is the DJ Motor 280mm rear shock, specifically the DNM MK-AR model. This shock features a 1,000 lb strength spring, offering robust support for heavier riders. It is readily available on Amazon, priced around $129.19, making it an affordable yet effective upgrade.

Additional Components: Flange Sleeve Bearings

When upgrading the shock, it’s recommended to replace the bushings as well. Flange sleeve bearings with an 8mm bore for a 10mm hole provide better fitment and durability. These cost approximately $7.59 and help ensure smooth operation and reduced wear.

Tools Needed for Installation

• Small hex key
• 10mm socket wrench
• 10mm wrench
• Rubber mallet or hammer
• Optional: spanner tool for spring adjustment

Having these tools ready will make the upgrade process smooth and efficient.

Step 1: Removing the Existing Shock

1. Begin by removing the bolts securing the side panels to gain access to the shock. Use the small hex key to remove these bolts carefully.
2. Next, use the 10mm socket and wrench to loosen and remove the nuts on both the top and bottom mounting points of the shock.
3. Gently pull the shock out, taking care not to scratch or damage the frame. The rear may collapse slightly once the shock is removed, so support the bike to prevent it from tipping over.

Step 2: Preparing the New Shock

1. Insert the flange sleeve bearings into the mounting holes using a rubber mallet or hammer. This ensures a snug fit and reduces wear.
2. Confirm the orientation of the shock spring. While the direction isn’t crucial, aligning the lettering outward can help with future adjustments.
3. If you plan to adjust the spring tension later, consider the positioning for easy access with a spanner tool.

Step 3: Installing the New Shock

1. Position the new shock in place and align the mounting holes.
2. Insert the bolts through the shock and frame, then hand-tighten the nuts to keep the shock secure but adjustable.
3. Use the 10mm socket and wrench to fully tighten the nuts, ensuring the shock is firmly mounted without over-tightening.

Step 4: Testing Suspension Stiffness

Before finalizing the installation, compress the suspension to test the stiffness. The upgraded shock should flex less than the stock version, providing better support. If the spring feels too firm or too soft, consider switching to a different spring rating, such as a 500 lb or 550 lb spring, to better match your weight and riding style.

Step 5: Final Adjustments and Ride Test

After tightening everything securely, take your Segway Cyber for a test ride. Pay attention to the suspension response and overall comfort. Adjust the spring tension using a spanner tool if needed, or swap springs for optimal performance.

Tips for a Successful Rear Shock Upgrade

• Work with a helper: Handling the shock and bolts can be easier with two people.
• Use proper tools: A socket wrench saves time and prevents damage to nuts and bolts.
• Support your bike: Remove the shock carefully and support the frame to avoid it falling over.
• Check all bolts: After test rides, recheck all bolts for tightness to ensure safety.
• Consider rider weight: Select a spring strength that matches your weight for the best ride quality.

Final Thoughts: Is the Rear Shock Upgrade Worth It?

Upgrading the rear shock on your Segway Xyber is a cost-effective way to dramatically improve your riding experience. Heavier riders or those who frequently tackle uneven terrain will notice increased stability and comfort. While the initial upgrade to a 1,000 lb spring shock might feel a bit firm, experimenting with spring strengths allows you to find the perfect balance.

By following this guide, you can perform the upgrade yourself with minimal hassle and enjoy a smoother, safer ride. Plus, the parts are affordable and widely available online, making it accessible for most Segway Xyber owners.
