Back in the day, many people had to ride their bikes in the snow uphill both ways if they wanted to get somewhere. Nowadays, you'll be able to ride downhill both ways. The Ibis OSO GX 20mph e-Bike is an enduro and all-mountain e-bike that is ready to take on any adventure. It has a carbon frame that uses 170mm of travel on the front and 155mm of travel on the rear. The OSO uses 27.5/29" wheels on the small and medium sizes and 29" wheels on the large and extra large sizes. The frame features internal cable routing, DW-Link suspension on the rear, integrated frame protection, a chain guide, and lights on the front and back. With the Bosch Performance Line CX motor and Bosch Powertube 750Wh battery, you'll get up to 20mph of pedal assistance so you can conquer any mountain.
The GX version of the Ibis OSO comes with a SRAM GX Eagle 12-speed drivetrain. This includes a cassette that has a hill-crushing 10-52T gear range that makes climbing and pedaling through difficult terrain much easier. Shimano XT M8120 4-piston hydraulic disc brakes provide superior stopping power so you can descend with confidence. Blackbird Send I/Send II rims are paired with Maxxis Assegai and Dissector tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the Bike Yoke Revive Dropper Post, you'll be able to quickly lift and lower your saddle with the press of a lever.
