Hello , The thickness of the foot is comparable to most plastic pucks I have here so take care when parking as usual. I tried to illustrate the angle of the bike when parked on flat level concrete with the foot installed.
I like it. Looks better quality that I expected. That was one of my questions when I saw how thick it was. These bikes sit pretty straight up and I think lessening the angle even more would worry me a bit. Also, that shiny steel bottom doesn't look like it has much grip if your facing upgrade. Hope it doesn't slide back on you. Maybe mounting a thin bit of rubber to the bottom? My driveway has a slight up grade and when I left the bike idling, it started to slide back a bit. All that aside, probably helps on a soft surface or hot asphalt.
