build a custom wide coaster hub bicycle

here are some details on making a wide rear coaster hub like the one i used on this bike.

Step 1 This is what you need

this assumes you understand how a coaster hub works and what it looks like inside.
you need two hub shells for a coaster brake, the complete guts for at least one of them and an additional cone nut/pad ramp thingy for another.

then go to grainger.com and buy a 3/8 24 threaded rod in three feet made of G7 alloy.

bang the spoke flange off the wide side of one hub

cut the narrow side off the other, you don't want the inside part where the coaster brake cone acts to move forward , use a level to trim the wide open side cut until it is lathe straight, got it?

it just occurred to me that you could just weld the brake pad nut to the new axle in a fixed position which would allow for more precise bearing adjustment with the outer nut.

Hard to ride? the handling is challenging, a long raked bike like this wants to flop the front end all over and it looks exaggerated when you steer it. the large rear tire is heavy and takes lots of grunt to get moving but good gear selection takes most of the sweat out. limited top speed and you lose lots of momentum when turning 'cause the tire scrubs bad. but you get used to it all and look really cool trolling at walking speed in a car show.

Looks cool. More pictures please, of the whole build. Also, what did you use for a rim and spokes? Thanks

I'll post pics when I can. check out AtomicZombie.com, he's the guy i got the basic bike plans from and the inspiration for this. the rear rim is from a car and the spokes are bicycle parts. got the plans from AtomicZombie again but his bike didn't have brakes and I needed them

Thanks, I have his book and have built from his designs in the past.
