Here we go! Three bolts to mount to the rack. My 55lb bike worked great, nice and stable driving around town. I'd recommend the rockymounts droptop for the fork mount. I bought an inexpensive Amazon Universal unit but it makes it a bit awkward with the thru axle mount on my bike. Would work fine if you have quick release skewer for front wheel. I used an wheel tray from an older bike rack I had to mount rear wheel but will make up some of our own to go with these bike mounts. How much will you be asking for a pair of these? Remember I got you to fabricate them?
