Category: Chupacabra Custom Chopper

Here’s a picture of what remains of the sacrificial bike. Parts and pieces of this bike (and another one like it) were also used on Chupacabra Custom Chopper build and the Lowered Adult-Sized Tricycle build.

Again I’d like to thank AtomicZombie.com for providing the plans, tips, techniques, design advice, and confidence that allowed me to build this bike. Their webisite has several plans for download; including plans for the “OverKill Phat Ass Extreme Chopper” — on which Chupacabra was built. They also have a book, Bicycle Builder’s Bonanza, which I recommend. Tips ranging from where and how to salvage bike parts to planning and designing your bike project.

The (almost) completed Chupacabra Custom Chopper.  [Need some grips]

Kickstands to make a center stand. Handlebars to make “ape hangers”.

This photo shows the offset between the rear hub and chain ring; hence the need for a jack shaft.

Because of the width of the rear wheel, the rear sprocket was offset very far from the chainring creating an alignment issue.  Therefore a jackshaft was needed in order to transfer power from the chain ring to the rear hub.

I fabricated this jackshaft using the freewheel sides of two rear hubs.
