SidewinderJerry's speed formula:
MPH=(RPM × Wheel Diameter × ⚻)÷(1056 × Total Reduction)

(10900 × 26 × ⚻)÷(1056 × (4 ×(22÷10)))=95.8 MPH.

(8533 × 26 × ⚻)÷(1056 × (4 × (22÷10)))=75 MPH.

To me even for 75 mph on level ground running a 10:22, one would need to be at least doing 45+ mph before the engine could drive the ratio. So unless he came down a steep hill first to get up to 45+ mph. This looks like B.S. to me.

I've run 11/26 gearing with my 27" wheel and it will pull out of the whole ok but it will never unload to 10k+ I'm lucky if it gets to 9k and as your speed formula shows the speed is over 70 and by the way it's 4.1 (20/82) for the engines gearing and that's how I got the 93.5 @ 10,900, it makes a difference, I use gear rat calc it's very accurate and was on this site for download few years back not sure if it's still available or not.

Is this the one your referring to SR???

It's obvious Little Care Bear (BBF) faked the 75mph M/B speed
He recorded the GPS 75mph speed in his car then put the GPS overlay on his M/B video

In Little Care Bears (BBF) attempts to expose others for making fake top speed videos he just busted himself

Motorized Bicycle Speed Runs The Truth Behind The Unspoken Lies Of Stupid Claims!

Just saying there is so much bs online with claims of speeds that are just absurd at times for what they have. Not saying this is not a few high end builds with saw jugs and moped jugs that could maybe do as they claim even so half that is Bs as well! just saying have few wild to mild builds...

Thanks for the update on the internal reduction on the 2 strokes.

 

[Sidewinder Jerry]

Then he'd need 8746 rpm to do 75 mph on 26" tires with a 10:22 drive.

10,900 rpm would yield a speed of 93.5 mph. I used my speed formula again this time with the 4.1 internal reduction.

For yours I came up with 74.6 mph on 27" tires with an 11:26 drive at 9000 rpm
