DIY Bike and Trike Plans

  • Who is Atomic Zombie?


    We are bike builders and co-authors - known as KoolKat and Radical Brad on the AZ Builders Forum - located in Ontario, Canada. Brad Graham has been building his own custom bikes for over 25 years. We launched Atomic Zombie Extreme Machines almost 10 years ago to showcase some of his creations, and it has grown ever since. We (Kat and Brad) design and publish DIY plans and have an extensive Builders Gallery and international Builders Forum.

    Our DIY plans detail every aspect of the building process using easy-to-follow instructions, high resolution pictures and diagrams. Even if this is your first attempt at building a bike, you will be able to follow our plans, as no previous expertise is assumed. Real photos of the project are used instead of complex drawings, so you will not have to guess when critical measurements are required.

    You will only need a minimal set of common hardware store tools to build any of our plans such as a welder, angle grinder and hand drill. To ensure that anyone can follow our plans, all welding was done with a basic AC stick welder, and the only other power tools used are an angle grinder and hand held drill. Although some of the trikes require a small threaded part to be machined, drawings are given and the costs are normally very minimal at most machine shops.

    No difficult-to-find or non-standard bicycle parts are used in Atomic Zombie Extreme Machines plans, so you can acquire parts at most bicycle shops, thrift stores, or even scrap yards. Our plans allow a great deal of modification as well, so you can adapt your project to the parts you have available, or easily add your own modifications to suit your individual needs and style.

    Most of the amazing bikes and trikes shown in our gallery were built by those who never considered taking apart a bicycle or turning on a welder. With a little patience and a few days of practice, you can learn to weld steel and turn scrap metal into a work of art. Our Builders Forum is a great place for new builders to share ideas and seek help when first starting into this great hobby. Membership is free, so join us!

    The Builders Forum represents an international community of creative people who enjoy building their own cool stuff! Our forum is family safe, meaning that we keep it clean and free from flaming, offensive language and trolling. If you want to talk about the things you are building and meet others who share your desires to create, then please drop by and join the discussions!

    We also encourage experienced builders who have completed projects based on Atomic Zombie plans to help other novice builders, so feel free to share your advice, tips and tricks with the community.

    Have to cut that black bit away from the seat back, it's not in use anymore. There should be 2 rods going from the upper portion to the rack, I just didn't

    It's tough to build a bike in the yard when you only have 1 day a week to work on it and you live in one of the rainiest parts of the country. Coming

    Now contemplating my next build. Most likely a two wheeled SWB recumbent, similar to the Spirit. I want to try laid-back riding on something a little
