Comparison of 3 Suspension Systems for Electric Bikes: A Beginner's Guide

When choosing an electric bike, the suspension system is one of the key factors that affect the riding experience. The suspension system not only influences the comfort of the ride but also enhances control and stability on different road conditions. For beginners, understanding the pros and cons of different suspension systems can help in selecting the most suitable electric bike. In this article, we will compare three common suspension systems: hardtail (no suspension), front suspension, and full suspension, to help you make an informed decision.

1. Hardtail Suspension System

What is Hardtail Suspension?
A hardtail suspension system refers to an electric bike that only has a rear frame fixed with a rigid design, and there is no suspension system on either the front or rear wheels. This design is the simplest, with a sturdy frame structure and a lighter weight. It is typically used in city electric bikes and light off-road bikes.

Pros and Cons of Hardtail Suspension
Pros:

• Lower Cost: The manufacturing cost of a hardtail suspension system is relatively low, and the price of the electric bike is usually more affordable.

• High Efficiency: Since there is no suspension system causing resistance, hardtail electric bikes can convert battery power into riding speed more effectively, making them suitable for flat roads.

Cons:

• Poor Comfort: The hardtail design cannot effectively absorb road vibrations, making long rides uncomfortable, especially on uneven roads.

• Lower Control: On rough or uneven surfaces, the hardtail system will subject the rider to more impacts, reducing control and handling.

Suitable Riders:
Hardtail suspension electric bikes are commonly found in city commuter bikes, light off-road mountain electric bikes, leisure bikes, and folding electric bikes. They offer a simple suspension system suitable for flat roads or light off-road terrain and are ideal for riders who prioritize lightness, ease of control, and lower cost.

2. Front Suspension System

What is Front Suspension?
A front suspension system refers to an electric bike that only has a suspension system on the front wheel, while the rear wheel remains rigid. The primary function of the front suspension system is to absorb vibrations from the uneven surfaces encountered by the front wheel, thus improving ride comfort and control. It is typically used by riders who need some comfort but do not require full suspension for the entire bike.

Pros and Cons of Front Suspension
Pros:

• Improved Comfort: Front suspension can effectively absorb the vibrations from the front wheel, providing a more comfortable ride.

• Light Weight: Compared to a full suspension system, the front suspension design still keeps the bike frame relatively light, suitable for riders who need some comfort but do not want to sacrifice speed and efficiency.

Cons:

• No Rear Suspension: While the front suspension handles the vibrations from the front wheel, the rear wheel still lacks suspension, which limits ride comfort on uneven terrain over long distances.

• Not Ideal for Extreme Off-Roading: If you plan to engage in long off-road rides, the front suspension might not provide sufficient comfort and control.

Suitable Riders:
Front suspension systems are commonly found in city commuter electric bikes, light mountain electric bikes, leisure bikes, folding electric bikes, and high-performance electric bikes. If you frequently ride on gravel paths, greenways, or slightly uneven roads, but do not require the extensive shock absorption of full suspension, a front suspension system can enhance comfort and provide a smoother ride across various city or suburban road conditions.

3. Full Suspension System

What is Full Suspension?
A full suspension system refers to an electric bike that has suspension systems on both the front and rear wheels. It can absorb the impacts from both the front and rear wheels, providing a higher level of ride comfort and better control. Full suspension systems are typically used in off-road electric bikes or by riders who have very high comfort requirements.

Pros and Cons of Full Suspension
Pros:

• Extremely High Comfort: The front and rear suspension systems can absorb shocks to the maximum extent, especially on uneven, rugged roads, offering a very comfortable ride.

• Better Control: Full suspension design effectively reduces the impacts from obstacles encountered during riding, improving control, particularly on off-road segments.

• Versatile: Whether on city streets or rugged mountain roads, the full suspension system provides an excellent riding experience, making it highly adaptable.

Cons:

• Heavier Weight: Due to the additional suspension components on both the front and rear, the overall bike weight is greater, which may impact riding efficiency, especially on long-distance rides.

• Higher Cost: The more complex mechanical structure means higher manufacturing costs, so full suspension electric bikes tend to be more expensive.

• Higher Maintenance: The front and rear suspension systems require regular maintenance and adjustments to ensure proper function, which makes the maintenance cost higher compared to other suspension systems.

Full suspension systems are typically found in professional mountain electric bikes, heavy-duty electric motorcycles, high-performance mountain/off-road electric bikes, high-end leisure/all-terrain electric bikes, and electric cruising motorcycles. They are ideal for riders who frequently ride on rugged, uneven mountain paths, muddy trails, or complex forest routes. The full suspension system can effectively absorb shocks from rough terrain, reducing vibrations and providing a smoother and more stable riding experience.

Adjust Suspension Damping for Different Riding Conditions

In suspension systems, damping is adjustable, and many high-performance electric bikes and motorcycles allow riders to adjust the damping according to their needs to adapt to different road conditions.

Spring Damping:
By adjusting the preload of the spring (i.e., the compression level), the damping effect can be altered. With higher preload, the damping is stronger; with lower preload, the suspension is softer.

Hydraulic Damping:
Modern suspension systems typically use hydraulic oil. There are two main types of damping adjustment:

• Compression Damping:
  Controls the reaction speed of the suspension system when it encounters impacts. Increasing compression damping slows down excessive compression, which is ideal for small impacts. For softer surfaces like city streets or paved roads, you can set a lower compression damping to make the suspension softer, helping absorb vibrations better.

• Rebound Damping:
  Controls the speed at which the suspension recovers after compression. Increasing rebound damping prevents the suspension from rebounding too quickly. For flat roads, setting a faster rebound damping helps the suspension recover quickly, improving handling and agility. On rough terrain, increasing rebound damping slows down the recovery speed to avoid the suspension rebounding too quickly.

Common Adjustment Methods:

• Compression Damping Adjuster Knob:
  Usually located at the top of the fork or on the side of the shock absorber. Turning the knob typically adjusts the intensity of the compression damping.

  • Turning it clockwise usually increases compression damping, making the system firmer, which is suitable for rougher terrain.

  • Turning it counterclockwise reduces compression damping, making the system softer, which is ideal for smoother terrain.

• Rebound Damping Adjuster Knob:
  Typically located at the bottom or side of the shock absorber. Adjusting this knob affects the speed at which the suspension returns to its original position after compression.

  • Turning it clockwise generally slows down the rebound speed, making the suspension recover more slowly, which is suitable for rough terrain.

  • Turning it counterclockwise speeds up the rebound, helping the suspension recover faster, which is ideal for flat surfaces.

Reminder:
Adjustment methods may vary depending on the brand. Always refer to the manufacturer's manual for specific adjustment details for your vehicle's suspension system. Typically, there will be dedicated adjuster knobs or levers for these settings.

Choosing the Right Suspension System

Choosing the right suspension system based on your primary riding needs is crucial:

• If you primarily commute on city roads and have a limited budget, a hardtail suspension (no suspension) may be the most suitable choice.

• If you occasionally ride on uneven surfaces and wish to improve comfort, front suspension is a great compromise.

• For off-road riding or riders who prioritize comfort and handling, full suspension will provide the best riding experience.
