New and old BIKES BY OTHERS!!!!

I may go farther with this idea, but, breaking away from the mold of recycling for a minute, why not try to go lighter? Make a monotube frame, trying to achieve a lightweight bike with a simple, easy to use geometry where the child sits low enough to be comfortable and reaches the pedals easily and comfortably.
I invite your comment on the following drawing:
Questions: I am trying to keep the seat down at 13" off the ground, thinking that sitting height with a foot on the ground is important to a child. Yes? No? I am keeping the BB below that - down at about 11-12 " right now. I think pedaling down and easy reach from street to pedal is important. Yes? No? Crank length for a child? Should an 8 year old have hand brakes? Coaster brake? How may gears are appropriate? My inclination is to make two versions - a single speed beater with a coaster brake, and a second model with maybe 10 speeds and good brakes. What size is the right target size? This model is 40" tall. That might be too young. Your thoughts?
Thanks for looking - I hope to hear from you. ADC |

That is
the 15" wheel of my minivan, for reference. This is the frame Peter
has, it looks better since he finished it, especially with a smiling young lady
on it.
This
is another frame, sitting in my TV down here. I think the rear
triangle is too long on this one. Dve is still fitting this
out for his son.
I also
tried a cut-down front fork for this one - I am nothing if not too cheap to buy
a short fork for a 16" wheel.
This is the geometry of the small Mach II bike, scaled on a 12" grid if the
image shows it.
It's
in the toy shop now. If you know a test pilot in East Milwaukee who
is 40" tall, ask him/her to give me a call.
