CyclErie eBike Brake Upgrade Package: Enhanced Safety and Reliability

At CyclErie, we're committed to keeping you safe on the road with high-performance upgrades tailored to the unique demands of electric bicycles. Our new eBike Brake Upgrade Package addresses one of the most common pain points for eBike owners: underperforming stock brakes. By retrofitting your bike with the advanced Clark's SYNC-4E 4-piston hydraulic brake system, we deliver superior stopping power, seamless integration, and long-term reliability—ensuring your rides are as safe as they are enjoyable.

Why eBike Brake Safety and Reliability Matter

Electric bikes are heavier, faster, and often carry extra weight from passengers, cargo, or accessories, placing immense demands on the braking system. Poorly designed or low-quality brakes can lead to dangerous situations, such as extended stopping distances, sudden failures, or loss of control in wet conditions or on hills. According to industry safety standards, reliable brakes are critical for preventing accidents—eBikes can weigh over 50-70 pounds and reach speeds of 20-28 mph, making effective modulation and consistent performance non-negotiable. Issues like air ingress in hydraulic systems or weak mechanical calipers not only frustrate riders but also compromise emergency response times. Upgrading to a high-quality hydraulic system like the Clark's SYNC-4E minimizes these risks, incorporating features like motor shut-off to instantly cut power during braking, enhancing overall control and rider confidence.

The Common Problems We Solve

Many affordable eBikes on the market rely on budget cable-actuated mechanical disc brakes or entry-level hydraulic systems that fall short in real-world use:

  • Hydraulic Brake Issues: Levers often allow air to seep past seals, leading to spongy feel, reduced power, and frequent bleeding services.
  • Mechanical Disc Brake Frustrations: Constant caliper adjustments are needed due to pad wear and rotor misalignment, and stopping power is inadequate for heavy eBikes, especially when carrying passengers or loads.

These problems result in frequent shop visits, rider dissatisfaction, and heightened safety risks. Our upgrade eliminates these headaches by replacing the entire system with a robust, low-maintenance alternative designed specifically for eBikes.

Our Solution: The Clark's SYNC-4E Upgrade

We replace your existing brakes with the Clark's SYNC-4E, a cutting-edge 4-piston hydraulic disc brake system engineered for eBike demands. This upgrade provides:

  • Powerful 4-Piston Calipers: Deliver exceptional stopping force with smooth, modulated control—far superior to stock 2-piston or mechanical setups.
  • Motor Shut-Off Integration: Automatically cuts motor power when braking, preventing unintended acceleration and improving safety during sudden stops.
  • Mineral Oil Fluid System: Ensures consistent performance without the corrosion risks of DOT fluid, while being easier to maintain.
  • Compatibility and Durability: Works on most common eBikes, handling the weight and speed of affordable models while offering reliable, fade-resistant braking even under heavy use.

This package transforms your eBike's braking from a weak point into a strength, giving you the confidence to tackle city streets, hills, and more.

What's Required for the Upgrade

To complete the brake system retrofit, we'll need access to your eBike for approximately 2.5 hours of professional labor. This includes:

  • Removing handlebar grips and accessories to install new brake levers.
  • Removing wheels to fit new brake rotors and calipers.
  • Bleeding the hydraulic system and adjusting for optimal performance.
  • Testing for safety and motor shut-off integration.

Most eBikes will require an additional length of brake hose for proper fitment. Some models may also need a Tektro TRP TL1.2 Disc Brake Hose Coupler Kit for compatibility. For large cargo bikes (e.g., Rad Power RadRunner 4 & 5), extra time is needed to navigate plexi-glass wheel guards, incurring a small surcharge.

Bring your eBike to our store for a quick assessment—we'll confirm compatibility and any add-ons before starting.
