I don't understand how he got the chain line to work?
If its real...it looks like the wheel is offset.
Is that a horn mounted down there at his nether-lands? I not sure he had the right idea about that part.
Yeah... I started building a fat bike and got hung up on the BB/ crank/ chain line
At first I thought it was an old-fashioned camera with a weird lens but now I think it's a horn. Must be hard and slow to blow.
Jack shaft with 2 bearings and 2 gears. You can mount the jack shaft high or low or forward to avoid the gears hitting the cross frame or more slick would be to have the jack shaft slide over the lateral frame member with roller bearings inside. The right side chain stay would need to bolt on (not welded) so you can install the jack shaft and it's two gears.
Offset wheels make for some really bad handling. I rode one like that. I had to lean as far to one side as I could just to go straight and turning the opposite direction was impossible.
Who needs a chain. A couple of beers into your brother and off you go.
This is from a late 1890's magazine.
How about this dandy? They make MT bikes with 36 inch wheels now. Big wheels are not new.
