Problem With Cyclepath

So I posted this in the official post for this website but decided to post this here too just to make sure people could see it. I've tried playing Cyclepath on IOS but can't seem to figure out how to make the bike start moving. The tutorial didn't really explain this. It said to press space on a computer but I'm not using a computer so that won't work. If anyone knows how to do this please let me know.

As far as I know using Cyclepath on your phone doesn’t work.

If you have a computer you can download Cyclepath on to it.

I hope this helps.
