High Traction, Wide 4.9inch Tires, SRAM 2X8 Speed Index Shifting is smooth and efficient

TRUSTED SELLER SINCE 1997

Over A Million Happy Customers

Customers compare to Trek, Specialized or Giant Fatbikes selling for around $800+. All with strong/light aluminum frames but the Bullseye has 2X8 Speed SRAM drivetrain vs 7 Speed.

How much does a fat bike weigh? These bikes are big and Big FUN. Big weighs more. Most average fat bikes weigh between about 30 and 40 pounds. How much do these fat bikes weigh? Compare specs, aluminum fat bikes with similar parts will weigh the about the same.

How do Fat Bikes ride? Way better than standard mountain bikes in snow? Yes. No Doubt. You'll ride over almost everything. Float over packed snow or deep sugar sand and laugh! You'll do tons more riding – and way less walking.

Awesome in rough conditions such as snow, deflate the tires to provide more traction. Compare Fat Bikes to the difference between a car and monster truck SUV. Your fat bike can go more places, like sport utility vehicles.

(Customers have told us they can fit up to 5 inch Speedster tires in the frame)
