Hold from the side and put a foot behind/under the tire to get something to push against. The foot also provides some feedback on how hard they are pushing back.
The ideal solo gate would have the countdown timer attached to the release then wheel itself off the track after the start - hopefully with a check to make sure the bike is not still attached.
