We designed our Earth Cruisers to be kinder, gentler versions of our sport comfort bikes. They’re simplified with easy-to-use coaster brake drivetrains without the complications of derailleurs or hand brakes to fiddle around with. In spite of their name, they’re not just for riding at the beach. They’re for any rider anywhere looking for a simple, lightweight, low-maintenance, good-looking bike they can casually and comfortably pedal around town all day, every day.

DIET CRUISER
Many cruisers weigh well north of 40 pounds. Not so with the Earth Cruiser.

Because nothing gets more uncomfortable faster than having to pedal more weight than necessary, we’ve pared as many grams from the Earth Cruiser as we could. Starting with the lightweight aluminum frame and a parts pick that’s nearly all lightweight alloy parts. The result is a 29-pound Earth Cruiser 1 that’s pure joy to pedal.

LOOKS GREAT TODAY & TOMORROW
Many of the parts specified on our Earth Cruisers are made of aluminum to save weight, but also to help preserve the finish of the bike. Aluminum parts include the seat post, seat clamp, stem, rims, front hub, kickstand and crank arms. We’ve even specified a silver-plated chain on the EC3 that doesn’t just look great, it’s way more rust-resistant than standard carbon steel chains.

COMFORTABLE STEERING
Our cruise-control handlebars were designed to promote a comfortable no-weight-on-the-wrists riding position. With just the right sweep and rise, these handlebars meet the rider’s hands without requiring a forward bend at the waist, relieving pressure on the back of the neck. Handlebar width has also been carefully calculated so that when steered from left to right it does not contact the rider, unlike many other cruiser-style handlebars.

MEMORY FOAM SADDLE
Our Earth Cruiser saddles are not just great looking, they’re extraordinarily comfortable as well. Though the size and shape is clearly generous, we’ve also molded a channel into the top of the saddle to relieve sitting pressure and use high-quality memory or polyurethane foam for the supporting mattress. Memory foam was originally developed by NASA and is now used extensively for medical applications. It is much denser than the foams ordinarily used in saddles, which makes it more supportive and more comfortable.

SMOOTH ROLLING TIRES
Our comfort tires have been designed to roll smoothly on pavement, but offer a large 2.125" footprint so that rides on park paths can be managed securely. The additional benefit of that big footprint is larger air volume in the tire and tube, which results in lower air pressure for a more comfortable ride than tires with smaller volumes and higher air pressures.

NO-SLIP PEDALS
Our Earth Cruisers pedals offer a thermoplastic elastomer insert on both sides of the pedal surface that keeps shoes and sandals from slipping when soles or pedals get wet. These inserts also make barefoot pedaling comfortable.
