Excellent fork!

Was an easy install on my Aventure bike. works and looks great!

Daniel Fidanza
Great product - fast service.

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.

Good quality Forks

I receive my Juggernaut mid-January but was unfortunate to have it run over early in February and had to replace the fork and several other parts. In doing the repair, I came to realize the high quality of the parts that make up this great bike. Biktrix was very helpful in shipping out replacement parts at reasonably pricing. The parts arrived quickly and the bike is good as new ( Just in time for the minus 30 degree weather here in Alberta... Looks like I won't be riding for a week or so!)
Thank you Biktrix

RST Suspension

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.
