    Easy to Follow

    Very easy to follow video, it gives you the confidence to tackle the brake change over which once you see the video you will know it's an easy to change.

    easy upgrade

    Posted by Jared on Feb 25th 2023

    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.

    Great, easy upgrade

    Posted by Jeff on Feb 25th 2023

    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.

    Solid upgrade

    Posted by Taylor Thompson on Feb 25th 2023

    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.

    Excellent upgrade for Taga 2.0

    Posted by Stig Morten Myre on Feb 25th 2023

    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.

    An Economical Upgrade to Ebike Mechanical Disc Brakes

    Posted by Brian Michael on Feb 25th 2023

    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.
