I've been reading back through this thread again. (My ATV lift is dodgy even with the stabiliser frame I added...) More than anything else I need a lift which I can store at least one of the bikes on top of and that doesn't increase the footprint too much. I'm very impressed with Roger's wooden box. In the value stakes and for storage ability it is a winner but I want to be able to get the bike on and off by myself so unless I go the full Evel Knievel and ride up the ramp, that one is out.
More and more I am impressed by Kiwi's home spun wind up job (see page 1). It is brilliant and with a few tweaks could be exceptional! I think I am decided to build a Kiwi style copy and make a few mods to suit my requirements but fundamentally I've seen nothing else that touches that one for ease of use, simplicity, ease of home build, low load height etc.
Tweaks I'm thinking of currently:
1, Ability to remove or fold the A frame up to vertical when stored
2, Castor wheels in all 4 corners (braked) in contact with the floor when bike is stored (lowered) enabling sideways movement into parking area
(I'm lucky to have a nice smooth, flat and level shed floor)
3, Additional locking/support mechanism on table to allow use at various heights without relying on winch/cable to take the load
4, Rear extension/hinge up ramp to accommodate longer bikes as required
5, Tie down points
Its a bit late but many thanks to Kiwi for showing us his lift
