This was shot on a very steep hill.

You've got to be kidding me - a steep hill - where - where is the steep hill?
Now point the bike up a 22% gradient and accelerate from a standing start with 100 lbs of bicycle trailer behind you, because that's my benchmark baseline.

This was shot from a cellphone. So its hard to tell how steep the hill is. I can coast to over 30 mph going down it and probably would be able to go faster if not having to stop for a stop sign. I live in a valley I could go about 10 miles down the road for even steeper hills.
Another thing to consider is I'm only using a 33 cc 1.6 HP engine. My bike weighs 89 lbs and I weigh 250 lbs. The next video I make I'll place a 8 foot 2x4 on the road with a protractor on it.
Here is how deceptive a camera can be.

My back yard is on a 20% grade. The only way to see that is by looking at my neighbor's porch.

Better you go out there and get that 8 foot 2x4 with a protractor on it.

Used a piece of unistrut instead of a 2x4.
Slopes vs. gradients vs. % grades are indicated below:
Slope (degrees) ！Y ! X ! % grade
11° ! 1 ! 5.145 ! 19.4%
12° ! 1 ! 4.705 ! 21.3%
% grade is 100 * Y/X (vertical rise / horizontal distance)
As you can see 11.5 ° is a 20% grade.

I'm not so sure.
Maybe the is a bit of cheating going on. The first photo is not clear enough to read the number scale and the second photo is a closeup that does not show an 8 foot 2x4 with a protractor on it.
A Unistrut might be giving false readings and it doesn't qualify because it's not an 8 foot 2x4.
When was the last time you seen a Unistrut growing on trees, and when was the last time you seen a Unistrut being defended by environmentalists; preventing the lumberjack from cutting it down.
I've never seen a cabinet maker working with Unistruts to make a set of stairs or a door or a crystal cabinet, because it's not made of wood, and this may very well affect the result.
I'll believe it when i see you use an 8 foot 2x4 that has been certified by the American Lumber Foundation, complete with a photo of the certification documentation and a photo of the certifier holding a copy of the local newspaper with the date clearly visible, as well as the documentation being signed by a justice of the peace.
In this day and age of cheating, you can't be too careful.

There's a right triangle right above the protractor. Some 8th grade level math is all it would take to figure it out.

Very impressive, Jerry! Where do you get a freewheel crank? That is cool!
