Tomahawk / Perigee recumbent lowracer - Atomic Zombie builders forum
"Perigee: The point on a satellite’s orbit when it’s closest to the earth.
I bought the Tomahawk plans because I had asked Brad to design a low racer. I had started one of my own design back in Janurary Low Racer Thread but decided I wouldn't get it done in time for the Februrary HPRA event, I wound up racing my rike. I used the stays to start a Highroller project but it too stalled for a multitude of reasons, not the least of which is that I'd rather ride than build. So I cut the stays back off the Highroller and prepared them for use on the Perigee."

The Tomahawk Lowracer is all about the speed! The extremely laid back seating position means that you will always be able to deliver your full energy to the cranks, as well as cheat the wind in ways that are impossible on a standard upright bike. The short wheelbase configuration offers agile and responsive handling characteristics that make it feel as though you are piloting a jet fighter.
The building process is designed to allow anyone with a Do-It-Yourself desire to finish his or her own version of the Tomahawk without requiring previous bike building experience or specialized tools and skills. The plan is laid out in a format that makes customization or alternate parts usage a breeze, so you will certainly be able to include your own imagination in the process of building a fast lowracer.
With the adjustable bottom bracket and unique frame design, riders with shorter legs will be able to pilot the Tomahawk without dealing with crank interference with the front wheel. Before you start cutting your frame tubing, it is a good idea to read the entire plan so that you understand how modifications may affect the rest of the build. There is plenty of room for your own design changes, and the Tomahawk can be built using the parts you have available to you.
Take a look at our Builder's Gallery to see some other lowracer examples, including many creative modifications to the plan. Our international builders community ranges from students to retired engineers, but they all have one thing in common - the desire to build their own stuff!
