Will this fork fit my bike?

The best fork for Fat Ebikes!  This will fit the Sondors, Rover, and other Fat ebikes using a straight steerer tube and standard quick release axle.  Tires above 4.5" are not recommended as the fit can be very tight.  Fork is setup for 160mm rotors, please use a brake adapter for larger rotors.

    No matter what air pressure you set at the fork sags to mid-travel, it becomes stiff. The fork was sticky the first time I used it, I recommend Slick Honey fork Lube to fix the problem. China doesn't know how to lube, they use a drop grease and call it good.

    New ebile install.

    After proper installation and sag setup, forks performed excellent. Very satisfied. Just the stiffness alone was amazing. No more "axle tuck" under hard braking! Thanks guys!

    These shocks albeit on my bike for less than 20 hours look and feel great. They fit perfectly in my Juiced Rip Current S. They seem a slight step up in quality. If you want top quality look at 600 up in parts. These are quality forks and at a great price point. My original forks would have been fine until my daughter crashed.

    Does not fit the Radrunner 1

    Posted by DA on Feb 26th 2023

    Nice looking fork high quality etc. but the 20" does not fit the Radrunner. I had a professional try and install it but no luck. All kinds of issues given the geometry of the Radrunner frame.

    This fork is 3 1/2 pounds less then the rad Rover, better low-speed handling, excellent on big bumps, makes it feel like a whole new bike! Fits the Rover with no modification, the bike feels more nimble and alive! Went to lbs, had them removed the old crown race and put it on the new fork, had them install a new star nut, $20. Just a great improvement to the radrover!

    Bolton fork for rad runner

    Posted by john rudzitis on Feb 26th 2023

    I upgraded my stock fixed fork with a Bolton suspension for on my Rad Runner. Not to tough to do if you are handy. Needed to provide spacers for mounting the brake caliper, transfer bearing race to new fork, discard steering stem spacer and add to kickstand because bike sits higher. Ride quality on dirt trails is much improved and worth the price.
