Zoom H876E 2-PIN/3-PIN 4-Pistons E-Bike Electric Power-Off Hydraulic Brake Set with 180mm Rotors, Pre-Bled Hydraulic Disc Brake Caliper Lever for eBike (Included Mounting Adapter)

This was an extremely satisfyibg upgrade on my sons ebike. Swapping from mechanical to 4 pistons provided some of the most noticeable performance improvement and is just flat out safer for him ... the red levers and calipers match his theme he was going with... i think they look amazing.. this is a no brainer upgrade if your kids have ebikes with mechanical disc brakes.. install took about an hour for everything.. levers have good pull and my sons arms arent pumped after 10 minutes of riding anymore.. we go for longer rides simply because of the new mechanics of the brake upgrade.. extremely satisfied with this purchase .

Bought 2 of these for my 2 ebikes. Has these for 2 years. Great stopping power

These brakes were awkward to connect to bike took me about an hour all works well only thing is the electric sensors did not work

I bought this product to replace the mechanical brakes on my E-Bike. The previous brakes worked but were very average especially the back brake. I bought the 3-pin version in black, and the product arrived about a week or so later, as described in the listing. The product consists of a box containing a pair of rotors, the front and back callipers, the left and right levers and a set of adaptors to suit different kinds of mounts on the bike along with some screws, olives and other parts to install them, i.e. as shown in the picture. The box also came with a small leaflet indicating that the supplier had a video showing how to attach them. I have never fitted hydraulic brakes before, so I mailed the company. Their representative, Joe, was very helpful. He sent me a video using WhatsApp and answered my questions. The video was very useful, and I found a couple of others on YouTube. Having Joe around to answer any questions I had made the task both easier and a pleasure. He was very helpful. In my case, my bike has an IS mounting for the back calliper and a post mount on the front. The relevant adaptors were in the kit. So I simply fitted the parts and then attached the callipers to the levers. Attaching the hose to the lever took some care, but the video supplied covered that in detail. The only difficulty I had was that the product is supplied with male Julet plugs, and my bike was expecting female ones. So, I took the old level cables and cut, soldered and crimped the connections onto the new levers. I am glad I made this change because these brakes are a massive improvement from what I had. They have a very positive braking action, probably because of the four pistons. The adjustment was a breeze. It is a very good product. Having used them, I'd hate to go back to mechanical ones.

I have a long range, touring e-bike that weighs around 150 lbs with 45 Amp hours worth of batteries. Using cable braked I often found myself in some dangerous situations which ultimately caused me to reduce my average rates of travel and to start brake very early. No, I travel full time at top speed and can almost stop on a proverbial dime, if you will. It's like it's an entirely different ride. Just pull the trigger and buy it. NOTE: keep you original brackets and bolts from you current brake system, as you may need some of them to properly fit this system to you bike.
