This idea was born because we don't have enough place for all the bikes side by side including the car in our garage.
So we lift up the two not so oft used bikes and have space for the two frequently used bikes under them.
Easily build from a wooden board, a switch, a Tabulator Motor and two ropes or other strap.
Works quite, easy and comfortable.
Even for the children easy to use.
Once you switch to "move up" you can leave. Bikes will lifted up alone.
