I have researched lots of these bike hoist systems and decided to jump in with this design (actually I've bought 3 units for 3 bikes). To be truthful they mostly look the same in the Ads, so it was a gamble. Lots of feedback from people saying that the support hooks on many of the hoists on Amazon. Most say that they aren't hooked enough, and this one suffers from the same issue, which does leave you feeling a bit uncertain about hoisting your expensive bike(s) 4 or 5 feet off the floor. Not to mention the risk of getting 'brained' by a falling bike!
So what's the answer? Easy really - bend the damned hooks until they do actually resemble a 'U' bend and not the slightly bent 'L' shape that they arrive with. Problem solved!
Another issue mentioned by some people is the quality of the cord used for actual hoisting. These units have decent soft finish cord (can hardly classify it as rope). It's plenty strong enough for the job and soft enough so that you don't have to wear gloves to handle it. I would be sexist if I said that last comment was aimed at the ladies, but it's what my wife said about getting her bike down. Don't shoot the messenger ;o)
Would I recommend this hoist? Without doubt - it is well made, easy to assemble and works well. Not too much effort required to lift and lower a bike so I guess even the average teen could do the job without much risk, after demonstration of course.
However you will need to get those lazy mans hooks bent into proper 'U' bends before hoisting any bike. Overall I love them for freeing up a lot of space in my garage. Only a single garage so floor space is at a premium. This is the one to buy, quick delivery and well packaged so don't worry on that score.
Buy one and you won't be sorry.
