Oh. Lol. Yeah, you don’t ride your bike on it. You get off your bike and put the bike in the groove there. Then, you walk up the stairs using your bike’s breaks as needed while pushing/pulling the bike up/down the stairs. The bike’s wheels fit in the groove so the wheels spin easily while traversing the stairs. It’s a very common thing here.
