Frequently bought together
You squeeze the lever on a wet road and the motor cuts out the instant the caliper bites.
This is a hydraulic brake set for electric bikes and scooters, machined from aluminum alloy so it stays light on the bars and resists corrosion through season after season of road spray. The 2-pin power-off connector ties the lever into the motor circuit, so the moment you brake the controller drops power and the wheel slows under hydraulic pressure alone.
The set ships as a caliper with its oil line already routed, roughly 1350mm for the front and 2000mm for the rear so the hose reaches the bars on most frames. The caliper mounts on a 51mm hole spacing, and the lineup splits into the XD-H800 for one side and the XD-H880 for the other so you can match left or right installation.
Key Benefits
- Power-off braking The 2-pin connector cuts motor power the instant you pull the lever for a controlled stop.
- Aluminum alloy build The machined alloy stays light on the bars and resists corrosion from road spray.
- Waterproof performance Sealed against moisture so the brake holds its bite in rain and wet conditions.
- Routed oil line The hose ships pre-filled at roughly 1350mm front and 2000mm rear to reach the bars.
- Standard 51mm mount The caliper bolts to a 51mm hole spacing common on electric bike and scooter forks.
- Left or right models XD-H800 and XD-H880 cover both installation sides, sold single or as a pair.
Best for: riders replacing a worn brake or upgrading an electric bike or scooter to hydraulic stopping with motor cutoff.
Why It Works
Hydraulic pressure gives a firmer, more progressive squeeze than a cable, and the power-off circuit means the motor is no longer fighting the brake at the moment you need to slow. The alloy caliper sheds the weight that adds up at the wheel, and the sealed design keeps water out of the piston so the lever feel stays consistent on a wet commute.
Quick Product Facts: Material: aluminum alloy; Fits: electric bicycles and electric scooters; Connector: 2-pin power-off; Oil line: about 1350mm front, 2000mm rear; Weight: about 780g per set; Caliper mount: about 51mm hole distance; Models: XD-H800 and XD-H880 for left or right install.
How It Fits Your Routine
On the daily commute the lever sits under your fingers and the power-off cut makes stop-and-go traffic predictable, with the motor releasing the moment you brake rather than lurching against it.
When you service the bike, the 51mm mount and routed oil line drop into a standard fork without re-bleeding from scratch, and the model split lets you order exactly the side you need.
Through rainy weeks the sealed alloy caliper keeps water out, so the brake still grabs cleanly the next morning instead of feeling spongy.
FAQ
Does it cut the motor when braking? Yes. The 2-pin connector ties into the controller and drops motor power the instant the lever is pulled.
What does it fit? Electric bicycles and electric scooters with a 51mm caliper mount that accept a hydraulic line.
How do I choose left or right? The XD-H800 and XD-H880 models are made for opposite sides; pick the one that matches your install, or buy the pair.
Is it waterproof? The caliper is sealed against moisture so it holds braking force in wet conditions.
