HB-100 Line Pulling Hydraulic Disc Brake Calipers，Mechanical Disc Brakes for MTB, Mountain Bike, E-bike and Electric Bike 2PCS Front/Rear Black/Red/Gold (Blue)

I have a Gotrax F2v1 and it came with squeaky mechanical brakes. They require constant adjustment after 300 plus miles of riding. Stopping power was just okay. Upgraded to this xtech caliper and the install was a bit longer than expected and required a several adjustments. Be patient and make the adjustments so it doesn’t rub. I had to use the original bracket for the rear but the replacement bracket for the front. It took about 6 miles of riding and hard braking to break in the pads but now it stops on a dime. No shims needed like on some other e-bike brands I’ve read about. No more squawking like the mechanical brakes. I’m happy. And at 40$ this is 60$ cheaper than buying the full upgrade from the manufacturer or Amazon. They look nice in the blue color as well. Definitely safer stopping power. I would recommend this if you have a GoTrax e-bike with mechanical brakes. The performance is greatly improved!

Easy to install. Works great.

It’s best to bleed the brakes before you install the cable otherwise they work very well in the pads stop well.Great value for the product looks great and fits perfectlyIt comes with all necessary hardware

After getting my first ebike, the mechanical disc brakes did not have the positive stopping performance that I, or anyone for that matter, could depend on in an extreme situation. I carry tools which can add a lot of mass to a "downhill projectile" (especially since that bike does 40+ without pedaling). I love these brakes. Installation is relatively easy, patience is required for optimum adjustment. I, in fact ordered a set of these for my new ebike before it arrived and didn't even ride it until these brakes were on it.The best analogy I can offer is that "my bikes now stop as if they are performance cars."

I bought it for my ebike, the reviews seemed good enough and I heard from everyone how good and safe hydraulic hybrid brakes are for upgrading if you only have "regular" mechanical disc brakes. Didn't want to tinker myself, I had a LBS (local bike shop) install them for me.In just over 100 miles, the brakes lost all gripping power while I was riding, nearly crashing on the Manhattan bridge at 20 miles per hour because I couldn't stop in a reliable distance. Brought it back to the bike shop, who showed me that the cable system was fine, but the caliper just wasn't squeezing enough to put any tension on the brake disc. Garbage.If you value your life, and I assume you do because you're looking to upgrade your brakes, go spend the extra money and get the Area 13 Juintech M1 brakes. Don't try and save , it'll cost you injury. Or worse.

These brakes are a nice upgrade from the ones that came on my e-bike. The mechanical brakes it came with were pathetic, weak, and made all kinds of grinding sounds when you applied them. These brakes are nice and strong, quiet, and very easy to install. I put them on my wife's Heybike which had 160 mm rotors, and I put these on my larger fat tire e-bike with the 180 mm rotors. I did not need the mounting brackets that came with the calipers and simply left the OEM mounting brackets on the bikes and mounted these calipers to the OEM mounting brackets. Super easy to install.
