6' 5" giraffe

i am almost finished building a 6’ 5" giraffe, and i’m wondering what
size to use for the crank arm…i have a 7" arm on there now but i’m
thinking this is to big, also what size sprocket do i use for the upper
part and for the one on the wheel. would greatly appriciate any help with
this project.

Anything longer than 5.5" is unsuitable, in my opionion. A 7" crank will
make you positively miserable.

ordered the “how to make unicycles and artistic bikes” book and would
really like to build my own. <br>what are you using for parts and do you
have any tips. where did you get your design? Are there any good , online
<br>directions out there? <br>

i used my old mountain bike, i cut it up, had to heat and straighten the
forks a bit, my brother welded the places i need for me. i was looking at
other giraffes on the net for a design, but i kinda came up with my own
still need some parts…like crank arms,(short one’s). some sprockets and a
chain, then i’m off to break something…lol. i looked at this site for
some help with it
