I built this mini chopper alone, but I made lots of other bikes with my close friends, Verify them out on my youtube channel or my Internet site.

     Adjustable handlebar angle, throttle / brake sensitivity and tire air strain enables the mini chopper rider to totally customise this chopper for cruising.

The steering yokes (no less than I think that's what They can be termed. The bits the forks are mounted to) are Slash from 6mm steel applying an angle grinder / plasma cutter and drilled per the plans (1" hole for the forks.

to the drawing While using the wheels I also present the shape with the front fork. I commenced with a steel rod of six mm thick and bent it all over a round pipe. Start with a piece that's too extended and when you are satisfied with The form, Slash off the excess section.

I utilized the pedals bearing of a motorbike for a jackshaft, the pedals sprocket being a part of the primary transmission, and welded a bicycle sprocket over the chain noticed clutch. This method was a whole nightmare!

to be aware of the adjust in dealing with characteristics that final result from stretching the body, we need to have a look get more info at rake and trail.

after getting every one of the components, you can begin assembling the frame. This includes welding or bolting the body parts with each other, attaching the axle and wheels, and setting up the motor and clutch. You should utilize a body jig to ensure that all the elements are aligned the right way.

I utilized metallic and welded the vast majority of bicycle, due to the fact I preferred it being sturdy and never disintegrate. I you do not have welding machine or you cannot weld, you may however use the size from my drawings and I feel you can get quite far by using Wooden and glue.

If we go much bigger than five inches or so we would get a motorcycle that's seriously steady at speed, almost certainly dealing with sluggishly, and which at very low velocity will be tough to retain in line.

The elements are the identical dimensions. I bent Element of the side a little inward (that has a hammer along with the vise) as the frame with the again down below the seat was a bit extra slender.

Pretty much three months and a person bent axel, various stripet threads and damaged bolts, this mini chopper came out similar to this. The seat top is 19 inches whellbase …

I've produced 5 drawings And that i connected them each as Image and as PDF file. it's best to make use of the PDF file for printing. I applied a A4 dimension bit of paper to help make the drawings on the 1:1 scale. As printers can sometimes commit to scale the drawing to really make it fit the dimensions of paper you happen to be working with, I added lines on Every single drawing of one hundred mm extended (almost 4 inch) in both vertical and horizontal direction.

you are able to see the shape on the drawing. Then I Minimize two parts of thirty mm extensive and made use of them to connect the two halves in the frame. Their situation is likewise indicated over the drawing.

right after I finished the body, I measured things and sketched up some tough plans (see the files area to the PDF).
