Sup !
its been a little while, but new work place is re-installed and did a quick 1 week build to celebrate.

like the tittle said , its a chopper with single sided wheels , the rear one being a coaster brake hub , front one converted to sealed bearings
its got 1/2'' hardned seel axles front and rear that came from hydrolic dampers off of a elliptical exerciser machine.

and the front hub mod

flanges were removed , flipped , turned on the wood lathe to remove a few .001'' to fit the bearings ,and welded back together

axle also needed to be lather a few .001'' for the metric bearings i already had , it created a tinny shoulder that help with assembly

The vision for the frame and fisrt steps , used a road bike frame as base , extended top tube , joined a seat tube with a curved women frame part , used a 1/8''heavy duty tubing front to back for the single stay

somthing a little bit new , i had to find a way to have chain tension adjustment ,so i cam up with this , and gives me 1/2'' adjustment and is very stiff when tighten , it flex the downtube (no pivot)

rear wheel axle is held by a clamp type mount ,also with a axle tention nut , and a set screw to prevent rotation
 
i then flipped the BB with bolts cause i needed more ground clearance , it also ended up looking better :)
made the fork

and next day was paint ! ,
while it was drying i treated the old leather on the seat and cleaned some of the bolts and parts.
found some old space shuttle grips , got my worn out slick 3'' tire and bought a front skinny tire .

iam still waiting for a cheap crank i ordered but apart from that its pretty much done and feels strong free rolling (to be tested with chain on)
More pics to come
 
REALLY inventive build!
Looks like it’s going to be a comfy rider.

Does that paint have a matte finish?

thanks , ye chalk finish they call it

it was a confy ride for 5 min
untill i ate it !
cause the front fork broke on me just under the weld to the steerer tube :(
now idk what iam doing with this , iam scared of it now .

might try a other shot but will have to reinforce many things to gain back confidence to ride it
i wasent going fast so iam sort of alright
 
It looks like you could do the fork in one piece...no weld, no break?

If not doable as one piece...maybe temper/stress relieve the weld, and the area around it.

Jason
yes indeed it would be better 1 peice , but thing is i have no bender ... ill weld it back with rienforcement inside , probably reinforce the rear as well , i dont wana die ! :)
 
isnt it about time u make a bender? and i'm gonna be honest. the pics after paint looked so good i thought it was just a 3d model.. Great build.
