I remember pedaling my fake stingray, I think it was a Monkey Wards knockoff, up a huge hill, one I had been over in car a many times. This would be a 40-45 mph descent on my road bike these days. I had no idea how fast a bike would go down it, the thought never even crossed my 8 year old mind.
I can tell you that it's a sickening feeling helplessly flying down a hill like that when you're 8 years old, on a bike that small, with only a coaster brake.. But what was i gonna do, jump off the bike. I sure thought about, until I reached about 30 mph, and knew it would have been suicide.
Learned the art of "not soiling myself when I'm going WAYY faster than I would like to be going". It's a skill that still comes in handy every now and then.
