Crank Question

Not sure where else to put this, so here it goes.

As you can see by my sig line I have a Dyno Roadster that is kind of long. But, I still can't pedal the darn thing. The problem is my left knee won't bend far enough to allow my foot to make the full circle to pedal. I have tried moving the seat up and down. Still can't!

Would changing the crank from a kids bike make a difference? If the distance of the crank arm were shorter I'm thinking it might work. What are your thoughts?

Additional Info: I do have a centrifugal clutch so I really don't need to pedal. I just want to!

Thanks for the reply. I measured mine and it is 6.5". I found some 1 piece kids crank that are 4". At $7.95 I might just try it.

I don't use the coaster brake now because I can't get my foot back far enough to use it. I use a rim brake on the back.
