About This Upgraded Brake Set
Attention: Things You should know before ordering!
Before making a purchase, please confirm whether the original oil house on your ebike needs the oil needle to be cut for removal. If the original oil house can be easily detached, such as with our Bee Pathfinder and Bee Ranger series ebikes, you can choose to buy either the pre-installed or uninstalled version of the bleed line. However, if your original bleed house is difficult to remove, like with the Bee Adventurer and Bee Explorer series, and cutting the oil needle is necessary to pass through the internal routing, we recommend purchasing the uninstalled version.
Additionally, please ensure that you have sufficient installation experience and the necessary tools before ordering. This product is non-returnable if there are no quality issues, so please verify all the above details before placing your order. Thank you for your support!
1) The upgraded 4-piston brake system fits most ebikes with brake wire quick-release plugs in the market and as for BeeCool models, it fits all our ebike models but please pay attention to the red 2-pin plug's size. Some old versions of our ebikes have a plug diameter of 7mm while the plug diameter on our latest ebikes is 8mm. Therefore, if the plug diameter on your bike is 8mm, you don't need to do any modification but just use the upgrade brakes here perfectly on your BeeCool Bikes. However, if the plug diameter is 7mm on your BeeCool ebike, you need to replace the brake sensor wires on this upgrade brakes with the sensor wires from the original bike.

Things you should know before replacing the sensor wire:

Brake pads will come with the brakes and the pads offered are metal one. If you need pads for future replacement, you can refer to the pad size below:

2) We would only suggest you buy this upgraded brake system if you have enough skills and tools to operate it as shown in the tutorial video or if you are available to nearby bike shops that offer brake assembly service.

1) Experience Unmatched Braking Power: Unleash rapid and decisive braking aided by four pistons housed within each brake caliper, guaranteeing unwavering braking supremacy with every single ride. The system arrives pre-filled with environmentally conscious mineral oil, eliminating the need for manual bleeding and ensuring immediate deployment.
2) Crafted for E-Bikes: The HB890E system is meticulously engineered with an automated power-off sensor and seamlessly pairs with a 2-PIN male waterproof connector. Upon braking, the power output is instinctively severed, promising swift and effective deceleration.
3) Hose Length: The front brake boasts a 950mm (37.4in) hose, while the rear is 1850mm (72.8in), assuring a trouble-free setup process. Please strictly follow the video tutorial for the installation process.
4) Enhanced Performance through Amplified Components: The system incorporates original rotors, boasting an impressive 180mm diameter and 2.25mm thickness. This upgrade translates to unprecedented braking capabilities.
5) Innovative Caliper Design with Integrated Cooling Air Ducts: Prolonged, intense braking can lead to excessive heat build-up, potentially compromising braking efficiency. Our groundbreaking air duct design efficiently dissipates heat, preserving consistent braking power even under duress.
