I have three but of the locking type in the small picture at the bottom right. This allows you to lock the bike securely to the rack via the big metal loop thing.
They bolt to the wall and my kids swing on them for fun so I reckon they are pretty secure too.
You may need to hit/bend the wheel hanger to fit you wheel/tyre combo. If you do make sure you don’t mash the plastic sleeve on the wheel hanger.
The plastic sleeve on the wheel hanger has split on one of mine but this was due to ham-fisted use.
Overall a sturdy and useable bike rack.
