RockyMounts MonoRail Add-On for 2" platform hitch bike rack. Fits kid's/BMX bikes with 20" wheels up to 48" long bikes with 29" wheels and fat bike

Inside the receiving end (the rack that's already on my car), the welds that secure the blue release trigger protruded, prevent the bolt holes from even coming close to lining up. It was annoying to have to grind them flush. Nobody wastes my time but me. Minus 2 stars for lack of easy installation.

Great add-on rack. Pricy but it does what I need it to do.The only negative is that the BLUE handle to lift and drop rack is a bit recessed underneath when the rack is lowered. Makes it a tad bit tougher to reach and pull and lift. Not an issue for me but my wife struggles to get the leverage to raise the rack back to the driving position.

holds the bike securely, but not a locking rack.

Having used the RockyMounts single bike rack for the last several years, I expected the add-on to be the same quality. After using it for several trips it is exactly what I expected. Great product.

The 2 bike base is 5 stars, love it love it love it. This was difficult to install as the bolts and the holes didn't really line up. My initial intent was to put this on and remove it when I didn't need the 3rd bike, which is most of the time, but due to the installation difficulty I just leave it on. Not a deal breaker for me, but a bit disappointing.

Solid product from Rocky Mounts. Easy to install and works just as flawless as the main monorail. I mainly ride or drive to ride with friends by myself. Being able to scale up and not sacrifice space when I’m not riding with others is key.

A little challenging to build but not bad. Extremely sturdy back rack for 2 bikes. Well built does not bounce around when driving. Bolt for trailer makes it very sturdy. Would like and extra 2 straps for tires. Locks are not the best i have seen, would like to see a heavy duty lock assembly. Easy to tilt down bikes and raise plat form up. Going to buy extender for a third bike. For the money compared to Thule and other products this is well worth the money and built just as good as name products.

Son unos estafadores ,me cobraron por un rack de tres y me mandaron para una sola bicicleta. Y encima se estan tardando para devolverme el dinero !!!!!!
