Juintech M1 hydraulic calipers! Front and Rear

These brakes are an easy upgrade. I thought I was going to have to run new lines to get hydraulic brakes. Just replacing the calipers is a great option. The brakes work great on my little fat tire bike. It is much easier to stop on the down hills. I truly is a 5 min upgrade.

Glad I took your recommendation! EZ upgrade for my Sondors!!! Now I have brakes... can lock up rear wheel! Bolton Ebikes is #1in my book!!!

This is a game changer! I upgraded my controller and LCD screen to go with my 500 watt on my Sondors X. The problem was it was much faster but I couldn't stop! It actually was dangerous. "All go and no slow". These easy to change hydraulic brakes make it safe again. The bike actually stops like a normal bike should. Thanks Kyle for making these available.

Easy installation on 2018 Rad Rover that provides a noticeable improvement in braking performance. A truly “ plug and play” install. It uses Shimano pads so finding parts won’t be difficult.

Ordered this pair to replace the two front brakes on my Taga 2.0. Quick and easy upgrade, using the adapters that came with the bike. Because of Taga’s twin brake setup, it still takes a bit of tweaking to get them both adjusted alike, but it’s much less fiddly than with the stock mechanical brakes.

I did order this caliper some times, I just put in a day ago my ebike working very good i like it, so far so good.

My brakes came today put them on and took it out for a test ride there works excellently very happy with the purchase

I ordered two sets of Juin Tech M1 hydraulic calipers from Bolton for my wife and I's Rad Rovers. They arrived about a week after ordering. Installation was fairly cut and dry after watching Kyle's install video. Took about 30-45 minutes per bike to get them on, centered and fine tuned. Very simple. Allows use of existing cables and hardware. Pay attention to which bolts go in which holes. On the Rad bikes the top bolt is longer than the bottom and the supplied bolts are too short. Using the factory bracket works great though. Adjustment is one screw for caliper width and barrel adjusters for cable tension. I used some sandpaper and scuffed up my rotors to give the pads something to grab. I then used disc brake cleaner on the rotors to clean them up. The M1's perform great. Quieter, more stopping power and faster adjustment. What I especially like is that they hold on the downhill, whereas the mechanical Tektros did not. Recommended.

I just installed Juintech M1 hydraulic calipers from Bolton Ebikes. Pretty easy install while watching the video over and over again. Had some problems with cable fraying on the front and it was hard to get in the eyelet hole. The back brakes for the 2019 Radrover didn't require any adapters so I just screwed it in direct to the mounting brackets that were built in the bike. I used all the Rad screws and none of the adapters that Bolton Ebikes included. Also hard get to the mounting screw on the back brake because its right next to the frame. I just took it down a 30 mile and hour hill and it stops with out any squeaks and faster stopping power with out much effort. Well worth the money $$ don’t wait like I did buy now before they sell out!
