Surron electric bikes have gained a stellar reputation for their durability, power, and versatility in off-road terrains. However, the performance of a Surron bike is not just about the motor and battery—it’s also heavily influenced by the various rear components that contribute to the bike’s overall stability, braking power, and handling. If you’re a Surron owner or considering purchasing one, understanding the importance of these parts is essential for both maintenance and upgrading your bike.
In this comprehensive guide, we will take an in-depth look at all the key rear components of Surron bikes, including the rear fender, rear wheel, rear suspension, brake system, and much more. Whether you’re looking to upgrade or simply curious about how these parts function, this article covers everything you need to know.
1. Surron Rear Fender
The rear fender of a Surron bike is a critical part that helps protect both the rider and the bike from debris, mud, and water during off-road rides. It is mounted above the rear wheel, shielding the bike’s rear suspension and drivetrain components from the elements.
- Material: Most Surron rear fenders are made from durable plastic, which is lightweight yet sturdy enough to withstand impacts from rocks or debris.
- Customization: Many aftermarket options exist if you’re looking to replace the stock rear fender, offering a variety of designs and colors to suit your personal style.
The rear fender is often one of the first parts to suffer damage during tough off-road rides, so it’s always good to have a replacement on hand if needed.
2. Surron Rear Wheel
The rear wheel plays a crucial role in the performance of your Surron bike. It is responsible for transferring the power generated by the motor to the ground, allowing the bike to move forward.
- Size: The standard Surron rear wheel typically measures 19 inches, but some riders prefer to upgrade to a 16-inch rear wheel. A smaller rear wheel can offer better torque and improved handling in tight turns, making it a popular modification for technical off-road riding.
- Materials: The rear wheels are generally made from aluminum or other lightweight metals to reduce the overall weight of the bike without sacrificing strength.
Upgrading or replacing your rear wheel can enhance the bike’s performance, especially in specific types of terrain such as rocky trails or sandy conditions.
3. Surron Rear Shock
The rear shock is one of the most important components of the rear suspension system. It absorbs the impact from rough terrains, allowing for a smoother ride and better handling.
- Size: The standard Surron rear shock size is about 260mm, but many aftermarket shocks are available for riders looking to fine-tune their suspension setup.
- Adjustability: Some high-end shocks offer adjustability for rebound and compression, giving riders more control over their suspension settings depending on the terrain they are riding on.
- Brands: Popular aftermarket brands like DNM, RockShox, and Fox offer high-performance rear shocks that can significantly improve your bike’s suspension and overall comfort during off-road rides.
Upgrading your rear shock can drastically improve your ride quality, especially if you regularly tackle rough trails or perform jumps and stunts.
4. Surron Rear Mud Guard
The rear mud guard is an essential accessory for protecting both the rider and the rear components of the bike from mud, dirt, and water. It functions similarly to the rear fender but is typically smaller and positioned closer to the wheel.
- Benefits: By keeping the rear shock and drivetrain clean, the mud guard helps extend the lifespan of your bike’s components and reduces the need for frequent cleaning and maintenance.
- Materials: Like the rear fender, mud guards are usually made from durable plastic and are lightweight enough not to impact the bike’s performance.
For off-road riders who frequently ride in muddy or wet conditions, the rear mud guard is a must-have accessory.
5. Surron Rear Light
The rear light is an important safety feature, particularly if you plan to ride your Surron on roads or in low-light conditions.
- LED Technology: Most Surron rear lights are LED-based, offering bright and efficient lighting that is both energy-saving and highly visible.
- Mounting: The rear light is typically mounted under the rear fender or above the rear wheel, ensuring it is visible to other riders and vehicles on the road.
If you’re converting your Surron for street use, the rear light is a legal requirement and essential for nighttime visibility.
6. Surron Rear Rotor
The rear rotor is a critical component of the bike’s braking system. It works in conjunction with the brake caliper and pads to bring the bike to a stop.
- Material: Surron rear rotors are typically made from high-quality stainless steel to provide excellent heat dissipation and prevent warping under heavy braking conditions.
- Size: The size of the Surron rear brake rotor can vary, but many riders upgrade to larger rotors for improved braking performance. Larger rotors increase the surface area available for braking, which can help reduce stopping distances.
A high-performance rear rotor can make a significant difference in your braking power, especially when descending steep hills or navigating technical terrain.
7. Surron Rear Brake System
The Surron rear brake system is crucial for both safety and performance. It consists of the rear rotor, brake caliper, brake pads, and the brake line.
- Hydraulic Brakes: Most Surron bikes are equipped with hydraulic disc brakes, which offer superior stopping power compared to mechanical disc brakes. Hydraulic systems also provide smoother and more precise braking.
- Brake Line: The Surron rear brake line connects the brake lever to the rear brake caliper. It is usually made from stainless steel or Kevlar-reinforced materials to ensure durability and resist damage from harsh riding conditions.
If your rear brake starts to feel spongy or loses power, it may be time to replace the brake line or bleed the hydraulic system to remove any air bubbles.
8. Surron Rear Suspension
The rear suspension is vital for providing a smooth ride and maintaining traction on uneven terrain. It consists of several components, including the rear shock, linkage, and swing arm.
- Rear Shock: As previously mentioned, the rear shock absorbs impacts and improves ride quality.
- Rear Linkage: The Surron rear linkage connects the rear shock to the swing arm, helping to transfer forces and maintain the integrity of the suspension system.
- Rear Swing Arm: The Surron rear swing arm is the part of the suspension that holds the rear wheel and allows it to move up and down. It plays a key role in the bike’s handling and stability.
Maintaining the rear suspension is essential for maximizing your bike’s performance and ensuring a smooth ride across all types of terrain.
9. Surron Rear Axle and Axle Nut
The rear axle secures the rear wheel to the swing arm and allows it to rotate freely. The Surron rear axle nut holds the axle in place and ensures the rear wheel stays aligned.
- Torque: It’s important to tighten the Surron rear axle torque to the manufacturer’s specifications to avoid issues with wheel alignment or stability. Over-tightening or under-tightening the axle can lead to dangerous handling problems.
- Wheel Spacers: The Surron rear wheel spacer helps to maintain the correct spacing between the rear wheel and the swing arm, ensuring smooth operation.
Proper maintenance of the rear axle and axle nut is essential for the safe and reliable performance of your Surron bike.
10. Surron Rear Pegs
The rear pegs provide additional foot support for the rider, particularly when standing up during aggressive off-road riding or performing tricks. They are typically made from aluminum or steel for durability.
- Adjustability: Some aftermarket rear pegs are adjustable, allowing riders to set them at their preferred angle for better ergonomics.
Upgrading your rear pegs can improve both comfort and control, especially during long rides or technical sections.
Conclusion
The rear components of a Surron bike are integral to its overall performance and durability. Whether you’re focusing on the rear fender for protection, upgrading the rear suspension for better ride quality, or ensuring your brake system is top-notch for safety, every part plays a vital role in your riding experience.
Maintaining these components, replacing worn-out parts, and considering upgrades can significantly enhance your bike’s performance, especially in demanding off-road conditions. From the rear wheel to the rear brake rotor, each part is designed to handle the rigors of electric biking, but they also require regular maintenance to function optimally.
