Extreme Terrain Vehicles – Recumbent Backcountry Trikes

Fat tire bikes have been all the rage for a while, but now, the fun and excitement of “go anywhere” with pedal power has spilled over into human powered recumbent tricycles! For trike pilots who have always wanted a machine that will take them far off into the remote hinterlands, far away from obnoxious automobiles, far off the beaten path of pavement, and into areas of raw earth, the time has finally arrived to get going! Fatrikes are here!

What is a Fatrike? Well, it’s a generic term that describes a recumbent trike with large knobby off-road tires and really ultra low gearing that allows intrepid backcountry explorers to have their way in the wilds. In other words, these newly available tricycles are specially designed, fabricated, and intended for rough country use and utility. They are not configured to go fast on pavement, but rather to go slow on dirt roads, or no roads at all. These trikes will test the mettle of the most adventurous and athletic off-road fanatic, and they make available the rest of Earth that conventional trikes were never able to roam.

ICE Full Fat 21the ICE extreme terrain vehicle

Most folks these days are referring to this type of human powered vehicle, whether bike or trike, as “fat tire” rigs. ICE makes the Full Fat. Utah Trikes makes the Fat Tad Crawler. Azub makes the Fat-Tris. TerraTrike makes the Rambler Fat. More are in the works, and will soon follow. The wave is rapidly growing. Crazed trikers worldwide are sending clear messages to the trike producers to give ’em these thrill machines because life has become too boring on paved automobile byways! There is no way to stop all this momentum. There is something in every one of us that screams to have one for those days when pressurized modernity has sent our brains to the boiling point, and we just have to get away from it all, let it all hang out, and have a whopping good time! The wilds are waiting … for YOU!

Ride in all weather conditions. Ride in the snow. Ride in the sand. Ride at the beach. Ride in the mud. Ride through areas where normal trikes could never go. Ride any type of terrain in any type of weather. Ride it all. Find your limits … then exceed them!

Want to explore the mountains behind your house, on those mysterious dirt roads that just invite your curiosity? Want to pedal off into the desert on two-track dirt roads for miles and days on end? Want to pitch your tent so far away from humanity’s insanity that no one will ever find you? Want to live on the wild side with all your gear? Want to be self-sufficient out there in the boonies, surrounded by feral creatures that take on frightening proportions once the sun goes down? Want an adventure like no other you’ve ever had?

Then clearly, you NEED a FAT TIRE trike more than anything else in the world, and you need it RIGHT NOW! There is no question about it. Life is too damn short to fill with excuses! There is never a good time to get out beyond normalcy, to jump off the edge, to feel the rush only the untamed Earth can provide. You’ll need some cash to start, at least $2024 USD, but if that is not a stumbling block for you, then the adventure is yours for the taking. The Earth is your frontier – rediscover all its grandeur on your FAT TIRE trike!

Below are some photos, movies, and links that will whet your appetite. The trikes range in price currently from USD $2024 to around USD $8500 or more, depending on which one you opt to acquire, and how many accessories you need. If you plan on simply short day rides in local abandoned fields or around town to impress your friends, you don’t need much more than the bare trike itself. But, if you plan on an overland jaunt through undiscovered territory for several days on end, you’ll need fenders, racks, panniers, camping gear, food, water, and other supplies. Depending on how serious you are, you may opt for goodies that bump up the price to USD $9000 or greater. You don’t need to be rich to have a fat tire trike however! Besides, money is boring – but fat tire trikes are FUN … make the switch!

Hostel Shoppe ICE Full FatScott Christophersen, pictured above, lead mechanic at the Hostel Shoppe says, “Since I have had my Full Fat, I’m loving the trike. It has been very cold here, but I have been commuting on it anyway. Three to four inches of snow doesn’t seem be a problem, as long as I can get traction with the rear wheel. I have been running about 6 psi in the tires (which means about 3 psi at 10 degrees F). The ride is very cushy, as one would expect with 4.8 inch tires. I have been able to run up and over some curbs without any problems. I’m looking forward to summer and being able to get it into the woods for some trail blazing. It has been a real head turner, with many people wanting a photo of it.

Or, if you want four wheels, Utah Trikes has this custom Catrike quadcycle:

Utah Trikes Army Green Quad 02The drawback to four wheels however is that in uneven terrain, one wheel will usually be lifting off the ground, placing immense stress on the frame and welds. With three wheeled trikes, this does not occur because transitioning from one plane to another, such as going down a steep hill and turning onto another steep hill running perpendicular to it, the single wheel allows a smooth interface with no wheel lift. This Catrike quad has no suspension, thus the issue with frame and weld stress. If compared to a Jeep, for example, which is completely suspended, one can envision the difference quite readily – imagine a Jeep with no shocks or springs! How long would it last in the extreme conditions Jeeps encounter?
