There is still room for improvement (e.g. the rear wheel rest) but it is definitely the best solution available out there that I could find for the tight parking space in my garage. The rack is well built with quality components and you can tell the design has been well thought out. Instruction and installation is straightforward and the rack is extremely easy to use, even my children can do it using the simple lock & roll technique. I have had them installed only for 1 summer but I expect them to last quite a few cycles of Canadian winter and summer without any issues.
