The craziness continues

Slow but steady progress. Welded the rear wheel mounts, installed the rear wheel, Avid brake, and rear stand. Original kick stand will be removed since it's no longer needed and it interferes with the jackshaft pulley. Last item to finish drive train is a 39 or 40" primary drive v-belt. The SBP freewheel fits perfectly to isolate the pedals from the engine. Even though the pedal chain extends outward from the frame, I'll still be able to use the original chain guard which extends all the way from the front sprocket, over the jackshaft to the rear sprocket.

Fuel tank and seat will be installed on the bench before the bike is moved to the floor to add the heavy springer front end. Fabrication of fender mounts and tool box will be last step before test ride and strip down for painting. It makes me tired just thinking about what's left, but I'm enjoying every minute of this fun build.

Nice to see a vid of you riding it when done. It will be a unique bike in a cool way. Why the stretch, just to be different design?

I don't think he stretched it at all, just put new replacement dropouts on it

The frame isn't stretched as a tandem but as a chopper it definitely is.

Need a big rear rack on that

I think it's stretched. Look at the tube extensions added. Could be wrong. What type of bike is that if the frame is untouched?

He stated it's an old Schwinn tandem bicycle. I don't think you'd want one to be any longer

The extended design makes oil changes and other maintenance a breeze because everything is so accessible. In addition, there is plenty of room to plug in a bigger motor, a Briggs flatty or a Predator, if need be. And there's room to slide the engine fore and aft to adjust chain or belt tension eliminating the need for an idler. But the biggest advantage is a more comfortable seating posture. The wheelbase on a bicycle is short because they weren't designed to have engines crammed into them. Anyone who's ever jumped on a Harley cruiser after riding a dirt bike knows what I mean. A couple of other bonuses are the built-in jackshaft provided by the rear crank, and the heavy duty steel frame that's stronger than a standard bike.

Tandem wheels are crazy. 48 12ga spokes is the norm for them

A rolling chassis is a big step, especially with a fully functional drive train.
