American Custom Bicycles in Steel, Titanium and Ti/carbon mix

Tamarack Treeline Limited Edition

With an eye on the weather and the opportunity that a colder season brings, we have put together a value-packed fat bike offer: The Tamarack Treeline.

The Tamarack is a performance adventure bike that’s ready for any winter conditions. Designed to be fun in the winter and fast in the summer, we’re able to pull these conflicting goals together in one bike through a clever combination of frame design and component choices. The bike is light, durable, simple, fast, and fun. Everything you want in any bike but may not have thought possible in a fat bike. Welcome to the Tamarack.

Let’s get ready for snow!

What is “Tamarack?”

The Tamarack is an evergreen tree often found high on wooded slopes where the trees give way to bramble and scree, often called the treeline. The word comes from the Algonquin for “wood used for snow shoes.”

Defining the Tamarack Limited Edition

What makes this bike different from a more typical Seven Treeline design? A number of features speak directly to riding throughout any harsh and diverse New England winter.

  • Durability and low maintenance: Riding in snow, ice, sleet, rain, and road salt are extremely tough on bikes. Fortunately, titanium is the toughest bike frame material, and in our hands you get a lifetime ride. For the Tamarack we’ve put together a complete package that will stand up to all that abuse and keep you rolling. We’ve focused our curated group set on durability and simplicity. Simple so that when your bike is packed with ice and snow it will still work as intended. Durability so that you can ride through the harshest months with little to no maintenance. To these ends we’ve included a 1x gear package. A carbon fork rather than suspension. Tubes rather than tubeless. Hydraulic brakes rather than cables – don’t worry, the hydraulics won’t freeze in 20 degree weather. We’ve also thought through a parts kit that’s easy to source replacement parts at low cost so you can overhaul your Tamarack each season with minimal investment.
  • Stable and predictable handling: We find that a quick handling overly agile bike is a mess to control in snow and ice. Not only does it make the bike challenging to keep on a narrow snow trail but it’s exhausting to muscle a fat bike around in deep snow for a couple hours. Stability, a long wheelbase, a low bottom bracket and center of gravity, and a long front end all provide a stable platform for surefooted snow riding. This geometry also works exceedingly well on trails, sand, and mud. Stability is seriously underrated in almost all conditions. Make no mistake, though, the Tamarack is still a performance adventure bike when the sun comes out.
  • Light weight and easy to control: Fat bikes and light weight don’t usually go together but the group set and frame design we’ve come up with is about as light as any fat bike on the market. We have a few tricks that make this possible without sacrificing durability. The lighter the bike the easier it is to handle in any conditions.
  • Your best friend in winter or summer: We think the Tamarack is the best winter riding bike available. This bike is also a performance all season bike. In the summer on sandy trails or muddy conditions or simply primitive trails the Tamarack will surprise you with it’s extremely worthy capabilities. We wager that the Tamarack will become your favorite adventure bike.

The Tamarack Treeline is the kind of bike we ride in New England winters – and summers! Join us for an amazing season.
