Schwinn Racer MX

I want to dimple the chain stays. Open to suggestions. Willing to buy a new tool.

This motorized bike has been in my stand for a few weeks now. Fixing it for a friend. My first experience with a motorized bike. Kind of fascinated by this now. I will be buying a kit.

Are motors allowed in build offs?

The way I dimpled chainstays in the past, was with a piece of iron pipe with an ID about the size of the stays cut longwise, a piece of 2" rod about half the size of the stays, and vice grips.

I've seen some welded to the grips since then, rather than.free.placed and squeezed.

I think so, as long as the bike is still pedal powered? @Captain Awesome @ingola @The Renaissance Man @SwissGuy

* Bike must be pedal powered and ridable

We allow it in the big BO every year. Gas and E are always written into the rules there

I ordered a motorized kit last night. If it isn’t allowed in this build off I can save it for the big BO. Or I can mount it after BO is complete.


This is silly, but I am really hesitant to cut off the pulley for a 3 speed. I don’t need it, but I am also a big fan of the SA 3 speeds and it seems like a shame to chop this off.

Got the bendix kickback apart. Will send everything through the ultrasonic and then attempt to assemble with new grease.

If it were me, I'd would leave the bracket for the pully on the frame. Especially if putting a motor on, it could be a mount pount for a few different things related to that.

Masked the area that needs to be dimpled

String to check frame alignment. Off by about 7mm

I don't think it'd hurt to leave that pulley or its bracket on there for now, especially if you're thinking about motorizing it later. Who knows, it could come in handy later. Besides, it's a klunker; it doesn't have to be perfect!

Hope the frame dimpling pays off! Those tires are going to look great on that Schwinn!
