OK here are my homemade bikes. They are made using aluminum honeycomb composite material as the frames on these bikes, there is NOT a tube frame in these bikes.
First I built the "Captian America" bike (formerlly know as the "Razor Bike", which was named that because of all the sharp points that have cut me several times ). There was a Schwinn Breeze head tube and bottom bracket epoxied into the composite on this bike, I also used the fork, stem and bars( bars extended 4 "), front wheel/tire, 2 speed kickback hub (LBS laced to standard 26" wheel), crank assembly, and seat frame (extended 2 inches), from the Breeze. The peel and stick mylar covering was for the Coasters BC 4th of July ride, and I liked it so I left it on. The mylar does coverup the rear wheel dropout.
Then I built the "Alumasled" using a Schwinn Co-ed head tube epoxied into the composite, and used the fork, front wheel, and 2 speed kickback hub (LBS laced to 24" wheel with 24 x 3 tire) from the Co-ed. The bottom bracket is an after market eccentric (so the chain ajustment is made at the crank not at the wheel ) epoxied in the composite. This bike uses 3 piece crank and stem from other bikes. It uses aftermarket cruiser handlebars (bent narrow and extended 4 inches), and pedals. The seat is homemade. This bike was edge filled so that the honeycomb is hidden and was covered in a wood veneer. For a stand I use a lug wrench hung on the rear axel nut.
Someday I am going to build a chopper and a trike, when I do I will show the build on RRB so you can see the process of building this style of composite bike.
