They look like interesting stands for sure. Shame the front stand goes under the front wheel. No way to get a tire warmer on, or remove the front wheel!What's the brand? How do they go sideways? It seems like all wheels are on the ground at the same time?
The little wheels on the stand are mate from rollers. They can “wheel” forwards/backwards and then “roll” sideways on the rollers.
The wheels can be purchased separately, try Googling “multidirectional wheels”.
