1 seriously underestimates the size and width of a bike
2 makes no sense - it's missing actual rollers or a trainer stand
3 is a 27" high seat that's only usable when I'm not at home
4...maybe, if designed with the bike
Sorry, I'll stick with kickstand and wall. If you could work in tool storage and basic work stand (just lifting the wheels off the ground) I might be interested.
