The WildKat Long Wheelbase Recumbent Bike


WildKat LWB recumbent has underseat steering.

The Atomic Zombie WildKat long wheelbase recumbent bike is a smooth riding and easy to build recumbent bike that you can create from our easy-to-follow plans. With underseat steering, a rear disc brake, and a comfortable recumbent seat, you can take the WildKat on that long country ride, or commute across town in pure comfort.

Basic bicycle parts and steel conduit frame design.

The under seat steering place the handlebars and controls in a relaxed position so you can enjoy the view ahead and relax, even with one hand off the wheel. All of the levers and shifters are taken from a standard bicycle or can be purchased new from any bicycle shop for minimal expense.

A 26 inch rear wheel.

The rear 26 inch wheel offers low rolling resistance and optimum top speed. With 26 or more speeds to choose from means that you can push it all out on the flats or drop into low gear to tackle that steep hill. All of the transmission parts are standard bicycle components and you have the option to use a rear disc brake or a standard caliper brake in our DIY recumbent bike plan.

The linked steering system gives the WildKat a small turning circle so that it can turn around in any city street. Handling is much like a regular bicycle, so if you have never ridden a recumbent bike before, there will be practically no learning curve at all.

Higher seating means greater visibility on the road.

The WildKat seat is high enough to offer a good stance in city traffic, and low enough so that anyone can plant both feet on the ground when stopper or when starting out. The relaxed and comfortable recumbent seat will support your back so that you can push hard on the cranks when accelerating or tackling a strong headwind, giving you some advantages over an upright bicycle.

Accessorize your WildKat recumbent with cargo carriers, fenders and lights.

By using the same basic geometry on the rear as an upright cycle, you can add all of the same attachments such as fenders, panniers, or a luggage system for carrying your riding gear. The WildKat DIY recumbent bike frame can be made using round or square tubing, or even salvage bicycle frame tubing, so it really is a minimal cost DIY recumbent bike project.

An affordable DIY recumbent long wheel base bike project.

Leave that uncomfortable upright bicycle seat behind and enjoy a relaxing tour on a super comfortable and smooth riding recumbent bike. You can build the Atomic Zombie WildKat in a few days using only basic tools and mostly salved bicycle components. And, like all of our DIY recumbent bike plans, no experience is necessary. Our plans will detail every step of the build using clear text and many high resolution photos so that you can create your own recumbent bike in no time at all.
