About Star Union
About Star Union
Star Union is an e-bike parts specialist with more than 40 years of experience making bike components. Its specialty is brakes: hydraulic disc brakes built for e-bikes and e-trikes, including 2-piston and 4-piston models and brakes with a built-in parking lock. You’ll also find all the parts to keep them working, like brake pads, rotors, adapters, hoses, fittings and bleed kits.
Beyond brakes, Star Union carries the upgrades and replacement parts e-bike riders need most. That includes USB-C rechargeable headlights and tail lights (one rear light even has turn signals), lock-on and ergonomic grips, throttles, bags, pumps, bike covers and mid-drive kits. Whether you’re fixing your own e-bike or work as a bike tech, it’s a handy one-stop shop for parts that can be hard to find elsewhere.
Orders over $29 ship free, and Star Union backs its parts with a one-year warranty and a 30-day exchange guarantee.
