I'm also very interested in this answer. Also, I have a 1-1/2" downtube, soooo....The ones I see are for 1 1/8 or 1 1/4 inch posts. On an older frame the post is 1". So yes, what is your source?

I'm about to pull the trigger and go with this mounting method, looks economical and sturdy. But my question is: how to you get the final drive from the jackshaft to the rear wheel? It looks like the bearing portion of that jackshaft plate is so big that there is no room on the drive side of the seat tube for any pulleys/cogs?well as it turns out i didnt mount the preditor vertical anyway i went with something i used on a previous build worked pretty good. im putting this on what i believe is a 53 schwinn. i need a daily rider ive been riding my 212 roadmster like crazy but i want to keep it in nice shape so i figure to get this 99cc preditor a shot before the snow flies so whatch think?

Ahhh, makes sense. I just bought 4 of those 1-1/8" mirror mounts and decided to mount my 79cc engine vertically. Plan on using 2 mounts for the engine, and 2 mounts staggered for jackshaft pillow blocks. Will post pics of the concept on my "Cheap B@stard" build thread in DIY once I get it sorted out.i cut the jackshaft bearing holder that is why you need the pillow block bearing
