Default Pure Brilliance...

I was browsing my local Craigslist and discovered something of sheer genius... Yes it will need a clutch or perhaps just be a pedal start but just the way the he has assembled this makes perfect sense.

maybe this is how I will do it

Not only no pedals, but are those foot pegs mounted by drilling through the small lower tubes behind the seat posts? Also, a quick release rear skewer.I see a good opportunity for structural failure. Put a freewheeling front sprocket, centrifugal clutch, and pedals, and then you have a better chance of a good outcome. Otherwise, I like it.

I think we're looking at a purely American Ricumbili with motor from lawn and garden equipment. And if the motor has a recoil starter and clutch =)
Wheeeeeeeeeeeee !

The only thing missing is a 1 liter soda bottle fuel tank.

If you want to build a bike without pedals....Go for it. Don't let anyone discourage you.

Nah I have to have pedals and motor. and if I have motor I want to be able to let it do the work and be able to keep my feet still.

On this bike the pedals would always turn.

I didn't think of all the ramifications until it was posted here and there were a couple comments

Weld the pedals in place. Cut the chain ring out of the equation somehow.

or just get a front freewheel setup. Then you could keep the pedals in place while the motors running.

I may have posted this already, but I'm getting old and forgetful, but the bike you posted is right in line with this one. Pure genius. You still have all the bike's gears. Of course, it's now a motorbike and not a pedal bike anymore, but it's at least a way to go. Yes, a freewheel crank could be used and I assume you could still pedal, but freewheel cranks are very expensive even if you can find one. And I'm sure you have to let off the throttle when changing gears or the chain will probably fly off.
