Review on Secure Your Bikes with MaxxHaul 50376 Threaded Hitch Locking Pin for Bike Rack 70210 by Rich Schobinger

August 6, 2020 Bike assembled and installed only. Haven't raced yet. Review. This 4 bike rack system seems pretty solid .All the metal is about the same size as the part that fits in a 2" receiver which is about 2" square tubing. Assembly was fairly easy despite the unclear instructions. The two collapsible parts make it easy and smooth. The pins fit snugly, so do the cotter pins. I only have one bike to test but it fit well in the rack, sat well on the soft rubber piece and fitted well. Well balanced. And the velcro is wide, strong and tight The bike feels reasonably secure and in place on the rack, but it can wobble enough that if the rack is tipped backwards, it may m to make room for opening the rear door of the car, the bike can touch the ground with its wheels vertically and remain there while the carrier does not impede access. Your car from the back door. It's nice to have that kind of flexibility. And it's not that hard to lower the rack while there is a bike (1 bike) on it. If I have more than one bike I would ask someone for help if I need to lower the rack. Overall I think this will work well enough for my needs. When an adult mountain bike is on the rack, the wheels hang about 60 cm off the ground. And the arm that the bike sits on is about 5 feet off the ground on my small SUV. (However, this may differ for different vehicles). Once folded to storage size, it's actually smaller than I expected. About 3 feet long. That's nice. And it's not too heavy to carry for short distances. Even when it's in the folded position but still attached to the car, I can't see the hitch in my rear view mirrors. So a completely clear view through my rear window. But I still see it on my rear camera when I start my car. That takes some getting used to. Cons: The first obvious one is the use of a proprietary or non-standard pin that holds the post attached to the 2" hitch receiver. The pin is threaded into the male part of the post until it eventually comes out the other side where you can place a cotter pin on it. And only from left to right. This system cannot be circumvented by simply not using the pin that comes with the bar but using your own pin or a locking pin as the male part of the bar screws into a hole. This is a regular sized hole so people can use their own pins if desired, especially with a lock and key. Update: Fixed the missing blocking issue. I bought a thick chain that is 2 feet long (maybe 18 inches). And a castle. I wrapped the chain around the diagonal brace on the bike rack, then threaded the chain through the chain loop welded under the hitch pocket and attached the chain. That's not the most elegant solution. But it is much stronger than clutch pins with locks. The chain cost me about $6 at the hardware store. A padlock can be anything. 2. minus; It feels like the post in the hitch receiver is rocking a bit. I imagine this would be a rumble and noise issue on a dirt road. But I should check it out before I comment. Update: I found a solution. It's called the clutch tensioner. Available for $10 and up. 3. scammers; does not hold a "girly" bike (without a crossbar). But there is a solution called "Tension Bar Bike Bar Adapter" or "Adjustable Bike Rack Bar Top Tube Adapter" for about $17 and up. Overall, the price-performance ratio looks good despite the threaded bolt. It feels strong and has the flexibility to lean back to the side. Update 8 I took my bike for a short ride on a bike rack. All in all it went well. But I did a few things before to make it work better. I noticed that the bike wobbled and hit the vertical bar, so I taped foam to it. I then wrapped the bungee around the bike and upright to keep the bike from rocking. This made for a smooth ride on regular paved roads. Having solved the problem of safety, the problem of the bike rumbling and shaking, I am very satisfied with this bike rack.
