Our Boss Cruiser is what we’d call seriously casual—designed to be low maintenance, built for comfort, but with the durability to be ridden every day for years on end. The versatile Boss Cruiser 7 gets you up to speed with a Shimano drivetrain and safely to a stop with dual hand brakes.

Legendary Frame Design
These one-piece single-loops stays with trailing dropout plate have been a Boss signature since 1980. Reducing the number of rear triangle welds makes these frames stronger and stiffer. And we don’t have to swage the tubes to a smaller diameter to mate with standard tabbed dropouts, allowing the stays to remain near constant in diameter, yielding an even stronger frame with a bigger, bolder style.

Many cruisers weigh well north of 40 pounds. Not so with the Boss! Because nothing gets more uncomfortable faster than having to pedal more weight than necessary, we’ve pared as many grams from these bikes as we could. Starting with the lightweight aluminum frame and a parts pick that’s nearly all lightweight alloy parts. The results are bikes just north of 30 pounds that are easy to pedal and more fun to ride.

Perfect Fit
All Boss frame sizes offer an extra long stem quill and head tube and hi-rise handlebars for a comfortable, upright ride position.

Easy To Sit On
The Boss Saddle is as plush as it gets—quilted top, wide body, fully stuffed, and double-loop springs

Smooth Rolling Tires
Our comfort tires have been designed to roll smoothly on pavement, but offer a large 2.35” 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.

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.

Rust Resistant
Many of the parts specified on our Boss bikes 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.
