This an amazing product! I have four mountain bikes I had to get off the floor so I could fit my cars in garage. I stumbled across Kradl and it seemed like the perfect solution. I wanted something that was convenient and easy enough for my kids to use. I ordered four and was surprised how quick they came. The install was amazingly easy after I found the rafters. I contacted customer care and was helped by Robert who walked me through the the initial setup. Extremely supportive and helpful with the process. This is a quality product that is fun to use and works! It really is amazing. Would definitely buy again if I need to lift more bikes.
