My unicycle (from Avenir) has a 20' inch wheel with cotterless cranks

If you have any instructions or links to videos on how I can fix him
please post it on here! I really want to save my darling unicycle.

Normally on a bicycle using a bottom bracket axle to anchor the
cranks, the flats of a square taper are hidden or very nearly so. I
don't know how unicycle axles are normally formed but it does take the
use of a standard 3/8" bar from a socket set to get the required
amount of torque. I forget what it is but can sense it on a clean
oiled undistorted taper. This probably wont exacly apply in your case
and a little remedial work may be necessary with a scraper. First of
all we need to find out whether it is a bolted or nutted axle and if
it is a bolted, whether it is hex head or hex socket. A photo from
the side of the cycle will show what type of dustcap is fitted to the
crank and we can go from there.
