A: Yes, my bike has been hanging for over a year. No problem
A: The hooks are not tempered. They are however very strong & hold any bicycle easily up to 55 lbs. The key to this lift is the hooks are not picking up the majority of the weight; leveraging the weight, distributed equally, between both spokes allows for an easy draw. The danger, if your bike is heavier than 50 lbs is—if you don’t attach the base of the lift in studs, you may find it coming down. You may want to use Drywall anchors that have a 75 lb. rating. The hooks will not straighten out.
A: If the studs are not wide enough you might consider nailing or screwing a board to them to attach the pulleys. The front pulley is approx 5.5 in long x 2 in wide; the back pulley is approx 7 in long x 2 in wide. As long as the pulleys are in a straight line for handle bars & seat, it should not matter the direction.
A: I had the same situation as you, so I got a length of 2x4 (slightly longer than the distance between the 2 pulley assemblies) and securely screwed that perpendicularly across multiple ceiling studs. I believe it crossed 3 or more studs. I used 3 1/2 or 4" screws to attach the 2x4. Then I mounted the pulley assemblies to this 2x4. An advantage to doing it this way was that I had a broader mounting surface (3 1/2 inches wide) for the pulleys, so I felt even more confident that it would work. It did..
A: I installed 3/4” thick plywood panels which spanned 2 ceiling hoist for each bracket vs 1 joist per each bracket ... this allowed me the availability of positioning the bike unit where ever I needed They work effortlessly
A: Yes I did if that way
A: I mounted the pulleys on separate studs. It was necessary to raise my kayak (not being used for a bike) above other storage in my shed.
A: I put a 2x6 across the joists and mounted to that.
A: It doesn't look to me like they would work on different ceiling joists. You could mount the hangers on one long board and then mount that board to two different joists. That might be the way to go. Good luck.
A: Nevermind ... I found a similar product with a higher weight limit
A: This model has a weight capacity of 50 pound.
A: I believe so
