I just purchased my second 1Up USA rack. Nothing wrong with the first one which was the standard Quick Rack rated at 50 lbs per bike. I wanted their Super Duty model rated at 75 lbs per bike.
I got the new one today and set it up for my ebike. I continue to be extremely impressed with all aspects of 1Up USA products. This rack is compact, light, easy to store, flexible, and extremely easy to load and unload bikes. I honestly can't say enough good things about the product and the customer service provided by 1 Up USA employees. I've owned a Thule and Saris rack in the past and can honestly say they are not in the same league as 1Up USA.
1Up sells many replacement parts for their racks should you damage or wear out a piece. They will also do some custom stuff if you need it. If you have a challenging setup, give them a call and they might have a solution for you. Trying getting that kind of service from the competitors.
The only downside to the 1Up USA product is the price. They are expensive, but I feel they are worth the price. Once you use a 1Up USA bike rack, it will probably be hard to go back to anything else. I spoke with customer support today and asked how many racks they sell. They are a little over 100,000 racks per year. I had no idea they were selling that well.
