a couple motorized cycle trucks I built

Here are a couple bicycle sculptures I completed this fall.

The blue bike has a frame I built mostly from scratch, salvaged head tube seat tube and bottom bracket. The top tank is 16 gauge steel which is a bit heavy for the purpose, but was easy to work with. The filler neck is from an automotive supplier. Worksman wheels with drum brakes. Whizzer engine with auto clutch. spray paint and oneshot enamel all by hand. Front platform and back tool box are diamond plate aluminum. Lights are truck marker lights, LED tail light, tractor headlight. Wood basket has maple for the uprights and hickory for the side slats, finished with wipe on polyurethane.

The red bike has a Worksman low gravity bike frame and wheels. I welded on a back engine mount as I had to tilt the engine to fit. I fabricated the tank out of aluminum, and it is much lighter. Any tanks I do from now on will probably be aluminum. The engine is a "80cc" happy time from spooky tooth. Lights run from the white wire. The expansion chamber is one I fabricated out of conduit. I found the port timing and used this site http://www.mh-aerotools.de/airfoils/javapipe_main_en.htm

Recently had a problem with the clutch on the blue bike. The bearings went to pieces while on a ride. It seems whizzer used ball bearings instead of roller bearings and it squirted the balls right out.

Beautiful builds! Very, very nice! You deserve a big hand.

I have Schwinn Cycletruck I'd like to put a Whizzer engine on, but alas there's not enough room for the engine. The center bar is too low. I understand that Schwinn did make a special Cycletruck frame to accommodate a Whizzer engine, but unfortunately mine isn't that version.
 
if anybody know flying cycletruck, plz tell him, his bikes are super nice!! and i would like to talk to him...i just got a low gravity model from workman.....and i would like a medium sized engine, but the most important piece should be the tank, and a close second the head/tail lights
 
Thanks. If you put a happy time style engine in the worksman it will fit fine. A whizzer sized engine will require some serious frame modification. on the happy time you might have to make an intake manifold to fit the carb (an easy task, if you dont have a welder just cut the pieces and take it to someone to weld), and adjust the engine mounting blocks or weld up an engine mount like I did.
 
wow, those bikes really are works of art, truly amazing, thats the cleanest nicest happy time build I have ever seen. Well done to you sir! The expansion chamber is fantastic too really really nice.
