Easy Upgrade! Well worth it!
Great item! This was an easy install and upgrade to our e-bike. Our e-bikes had cable actuated disk brakes. With a heavy e-bike, this left a lot to be desired. We also tow a doggy trailer. It took a lot of force and distance to stop with the stock disk brakes. This was a simple and cheap upgrade. The stopping distance was reduced substantially. Just a note that these were used on 180mm disks using the stock mounting adapter, not the ones that came with these. Took less than 20 minutes per brake to install. I selected these because they use to stock brake cable, thus maintaining the motor cut-out and brake light. Highly recommend!

Simple install and cheap but necessary upgrade for ebikes
Ordered to replace the very squeaky stock brakes (that I’d tried so hard to make work) on a Jasion X Hunter ebike. These should come standard as it really is almost essential. They installed in 5 minutes each. Took longer to cut the end cap off the old line than it did to install and align the new one. Squeak is gone, rubbing is gone, and stopping power is far greater. I don’t believe there were instructions but really there is no need they are very simple and function exactly like the old mechanical ones

Good upgrade
These are good breaks and definitely an upgrade from the single piston mechanical calipers that were stock on the bike. I installed them on my Aipas M2 Pro as I put it together. The bike is heavy and many reviews said the brakes were inadequate. The istallation was very staight forward and pretty simple. There are a couple of videos online to assist. I had my initial trial down to the bottom of the New River Gorge. No fade and good stopping power, even at higher speeds. I woould recommend this upgrade to a heavier ebike if it has standard mechanical breaks. Well worth the price and it is something you can tackle yourself with simple skills base.

Great Value and easy to install
These are great value and easy to install. These hydro mechanical disc breaks are great for replacement of very subpart mechanical disc breaks.They stop well and provide more safe braking than a very bad unsafe set of mechanical brakes.They are quiet on the brake. Easy to install.

Works fine
I bought these calipers to upgrade the mechanical disk brakes on my Lectric 2.0 brand e bike. The installation was easy and straight forward. The calipers look nice with the red finish. I dont know if they really do a better job at stopping the bike then the factory brakes. They do stop the bike and I dont have any complaints.

Good Looking
After installation and bedding in the pads, the brakes work well with decent modulation and power. But the hybrid system is quite heavy, much heavier than quality Avid BB7 Mechanical brakes. The red anodizing is very attractive.

Perfect retrofit and upgrade for e-bike mechanical brakes
Got this set to upgrade / retrofit the mechanical brakes on a Haoqi Black Leopard circa 2022. Installation is easy, and the fit was perfect. Help yourself by having the right tools on hand – brake cable tensioner and cable crimp. With those, fine adjustment of the braking tension is easy. They are smooth and they are quiet. Total install front and back was about an hour.

Fantastic! These are 100% better than the manual disc brakes my e-bike came with! Less effort on the squeeze of the brakes and they grab the disc and stop me about 15ft shorter than the old brakes would’ve…..worth the expense!
