Description

LEGENDARY FRAME DESIGN
These one-piece single-loops stays with trailing dropout plate have been a Boss and Taxi 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.

LIGHTWEIGHT
Many cruisers weigh well north of 40 pounds. Not so with the Boss and Taxi! 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 (and there are six to assure the best possible fit for greater comfort and more secure handling) 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, double-loop springs — and is offered in both male and female specific lengths and widths. The Taxi saddle is as durable as it gets, with an extra-thick 3 mil cover to resist puncture, a flat top that won’t pool water when the Taxi is parked in the rain, box section rails that will never bend, and double-loop springs that comfortably support passengers.

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 and Taxi 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 specially treated chain on the Taxi that protects the chain against rust in even the harshest conditions. In fact, this coating increases the rust-resistance of the chain up to 500 times (!) that of a regular chain.
