David D.wrote a review of Yakima SingleSpeed Hitch Rack on July 7, 2018
Familiarity: I've used it once or twice and have initial impressions
I purchased this rack about a month ago, and conceptually it's great idea/product. The problem is with the pin that attaches the wheel cup to the rack. The pin is flimsy and can easily become dislodged. If that happens the wheel cup falls off the rack which, in turn, will eject the bike from the rack.
Yakima issued a recall and promptly sent out a replacement pin. After following their instructions and installing it, I have found that the pin STILL becomes dislodged quite easily. Certainly it would come loose from the vibrations generated on the back of a car. I have absolutely no confidence in this rack and am quite certain that my bike will eject from the rack if I use it. I am currently working with Yakima to see what they can do to remedy the situation. Yakima is a quality company and I have every reason to believe they will somehow fix the situation for me.
In the meantime I cannot recommend this rack. Once they adequately sort out the issue with the pin it will be a great product. Until then I suggest you spend your money on a different rack.
