KOONDHEEND 4-Piston Front & Rear Brake Kit for Surron, Talaria, Segway — Hydraulic, Braided Lines

KOONDHEEND's upgraded 4-piston front and rear hydraulic brake kit replaces cable systems to deliver stronger, more consistent stopping power for Surron, Talaria, Segway, and compatible e-bikes.

This complete brake assembly is built for modern electric dirt bikes and high-performance e-motorcycles. It combines a four-piston caliper design, mineral-oil hydraulic lines, CNC-machined aluminum levers, and stainless-steel braided hoses to give firmer modulation, faster response, and improved durability compared with stock plastic-cabled systems. The kit is specifically matched to a range of popular electric models (see compatibility) and intentionally excludes brake cutoff sensors for simple retrofit installs.

Which bikes is this brake kit compatible with?

This kit fits several common e-dirt bikes and light electric motorcycles but is not universal. It was developed for Surron Light Bee and Light Bee X, Talaria XXX and Sting MX3/R MX4, Segway X160 and X260, and the eRide Pro SS. It is not compatible with Surron Ultra Bee or Storm Bee models.

• Designed to replace stock front and rear brake assemblies on listed models
• Excludes Ultra Bee and Storm Bee — check frame and mount points before ordering
• No brake cutoff sensor included; suitable where cutoff wiring is unnecessary

How does the 4-piston design improve braking for electric dirt bikes?

The four-piston calipers apply clamping force more evenly across the brake pads, creating stronger and more linear braking without a mushy lever feel. Riders notice shorter stopping distances, better modulation during progressive braking, and improved stability under heavy loads or steep descents.

• More even pad contact reduces warp and hotspotting under load
• Firm lever feedback enhances rider confidence and control
• Better heat distribution for steadier performance on long runs

What materials and hydraulic features make this kit durable?

The kit swaps fragile plastic cables for stainless-steel braided hoses and uses a mineral-oil hydraulic fluid rated for high thermal tolerance. Levers are CNC-machined aluminum with an anodized finish to resist scratches and corrosion, while hoses and seals are chosen for cold-weather reliability and long-term resistance to chemical degradation.

• Stainless-steel braided lines for 30% faster response and greater longevity
• Mineral oil hydraulic system tolerates high temperatures and -30°C cold
• CNC aluminum levers with anodized coating for lightweight strength

How difficult is installation and what should I expect during setup?

Installation requires basic mechanical skill and a safe bleed of the hydraulic circuit after fitting. Because the kit omits a brake cutoff sensor, electrical adaptation is simpler; however, checking rotor clearance, pad alignment, and proper torque on mounts remains essential. If you’re unsure, a professional mechanic can complete the install and bleeding quickly.

• Basic tools and a brake-bleed kit recommended for proper setup
• Follow torque specs and rotor alignment to prevent rubbing or pad wear
• Professional installation is recommended for first-time hydraulic upgrades

Who is this for? Riders who use their Surron, Talaria, Segway X160/X260, or eRide Pro SS for aggressive trail riding, hill work, or frequent descents will benefit most. This kit targets owners who want stronger, more consistent braking, improved longevity over factory plastic-cabled parts, and a professional-looking anodized lever finish. If you need a plug-and-play electrical brake cutoff, this kit does not include one—confirm fitment with your model before buying.
