Capitalizing on our experience building Fat Trikes. We created what we call the Mountain Trike 27+. More efficient and agile than a fat trike, the Trisled Mountain Trike features 27+ tubeless tires and rims making it perfect for Mountain biking style trail riding. It can also be fitted with many other different wheel sizes meaning you can have slick tired wheels for road use one day, knobby tires to hit the trails the next!
