Very cool! Which one of the Goldberg family made that thing? Is there a transmission in that engine or a clutch connected to that silver lever above the sign tape in the last pic?

i built one of those out of a 26" beach cruiser. ebay gas engine kit for bicycle. i ended up racing and beating some tourist on rental SYM DD50's about 10 years ago. depending on the rear sprocket, the bike can do 35+ MPH.

this is the Mark II version of my Motor-Pedal-Bicycle. the first version had medium height "Ape Hanger" bars. they made my shoulders burn on long rides and it was uncomfortable. it looked "Cool" as hell though.  it outran a pack of rental SYM DD50 mopeds one day. i was followed by a coworker and it went in excess of 35 MPH on Base one day. Fun Times! ---now they have kits that allow you to put Vertical Minarelli bore kits on these platforms. there are also modified bore kits that allow for "DIO" intake and 28mm pwk carburetors on these engine kits. i can only imagine it with a Yasuni C16 pipe and a Vert Zuma big bore kit on this engine. even more Fun Times!!!
35+ MPH on a gas engine Beach Cruiser was good enough for me. it probably did 40+ MPH, i did not have a computer/digital-speedo intalled at that time to verify.

I think I like the dual chains. Does this result in a more reliable or less expensive way to have pedal power and/or engine power? How do they operate separately? thanks!

jackrides there is a detent button on the clutch lever that is mounted to the handle bars. if you want to ride like a regular bicycle, you squeeze the clutch lever in and press down on the detent button to keep the clutch lever in the "disengaged" position.
you pedal the bike the like a normal bicycle. however, it is heavy as hell with the engine kit and you fight some of the drag from the engine drive chain, even though the clutch is disengaged.
you ride it like a normal bike, you get up to speed and then you "kick start" the engine by quickly squeeze/tapping the clutch lever. by doing that action, the detent on the lever releases and the clutch engages and "kick starts" the engine. when you want to come off engine power, you pull the clutch lever in and press in the detent button to keep the clutch in the disengaged position, and then you hit the Kill Switch on the throttle assembly.
it's a pretty neat contraption. it works. and it's pretty trippy doing 45 MPH on a 26" wheel beach cruiser that only has Coaster Brakes (push back on the pedal to brake). it gets pretty exciting LOL.
