Treeline S – Seven Cycles

U.S. Built Custom Bicycles in Titanium and Titanium-Carbon Mix

Plus Size Versatility

Our buddy Tim Brick, at Brick Wheels in Traverse City, MI, sent us these photos of their latest Seven demo bike, a Treeline S, built to ride as a 29+ mountain bike, or a full-tilt fat bike with 4-inch tires.

Versatility is value. At first glance, the Treelines are fat bikes, built for snow adventures, but we were never interested in just building fat bikes, as awesome as they are. We wanted the Treeline to be a valuable bike year-round, which is why we made them part of our mountain line. Roll the snow all winter long, and then swap over to plus-sized tires for regular trail riding.

Introducing Treeline

It is tempting to say we have a fat bike. Riders have been asking us for one for a few seasons now. But, what we have instead is Treeline, not just a fat bike but an all-season mountain bike with the ability to run super wide tires like most fat bikes, but also the adaptability to be a 27.5+ war horse or a long haul bikepacking rig.

Treeline can be a flat bar bike or a drop bar bike. It can run suspended or rigid. It can take racks. It can be built fully thru-axle or with QR front and rear. In short, Treeline is a fat bike worthy of being a Seven, capable of fulfilling all your winter dreams without being a just a one-season luxury.

The Treeline S is built with our Integrity™ straight-gauge tubing, ultra durable. The Treeline SL, built for long-distance comfort, features our Argen™ double-butted tubing.
