I’m very impressed with your product. The design is well thought out and easy to install. The workmanship superior. The welding, beautiful and clean ( that matters to me) it means your personal care what comes out of your shop. Sturdy and secure. The only problem I had was I lowered the lift too far and the bolt unthreatened and the lift dropped to the ground. Luckily I was able to get it back in the bolt and lift it back up. I am 68 years old and weigh 127. If I can do it so can you. It just takes some practice to lift the bike on the lowered rack. NOTE: wear some protective clothes on your arms so you don’t have bruising of an eighty year old when you are done!
