Need A Hand?
Found this fork, based on research for an upgrade to AWD ebike. Some manufacturers use this fork with front hub motors. It is solid, well made, and the dropouts a very thick and supportive. Read about how several newbies where breaking fork and flying over the handlebars due to front forks not being capable of handling the torque from the front motor. Others on YouTube used this fork and said it was suitable. After installing the fork and front hub motor, I agree that it is definitely suitable and string enough. Super pleased with the purchase and with Biktrix for the fast shipping.
This is a replacement as I finally wore out my old one after thousands of miles of rough mountain riding. It was installed on my 2018 Ultra FS. It does everything I need it to do and I’m happy Biktrix helped me out as the quick release forks are hard to find as the industry standard is now the through axel type.
