X-Treme Baja - 48 Volt Folding Electric Mountain Bike

Portability, Made Simple

The X-Treme Baja Folding Electric Mountain Bike is one of the best Electric Mountain Bikes on the market. The Baja is very quick, thanks to its monstrous yet smooth 500 Watt Bafang Zero Resistance Rear Hub Clutch Motor with Digital Torque Sensor. The Baja’s powerful and lightweight 48 Volt LiPo4 Lithium Battery (covered by a 1 year warranty) blasts you along for up to 70 Miles. All this is possible because the Baja comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS), allowing you to adjust power output between 5 speeds, and a Pedal Assist mode (allowing you to pedal while using throttle), all controlled from the ease of the Big LCD Screen attached to the Aluminum Alloy Handlebars. The Baja’s LCD Screen also shows Speed, Distance and Battery Life. The Baja charges in just 3 hours.

The Baja is a true mountain bike, featuring an Atlus Shimano 9-Speed Gears & Shifting System, Suntour XCT Front Suspension & KS Rear Shock Suspension, and Aluminum Rims with a Quick Release Axle on the Front (and a waterproof quick disconnect on the rear), meaning you can conquer any path, trail, or road in any weather condition. The Baja rides on 26” x 2.1” Kenda Mountain Tires and Tubes, on Aluminum Wheels. The Baja is lightweight yet incredibly sturdy, capable of supporting up to 350 lbs, thanks to its 100% Aluminum Hand Welded Frame. Everything on this bike is Aluminum; nut, bolt, spoke; you name it. That means absolutely no rust!

The Eco-Friendly Baja folds completely in half, making commuting and storing a breeze. The Battery is located inside the Bicycle Frame for protection, and can only be accessed when the Bike is folded. The Baja comes standard with Front and Rear Tektro Disk Brakes, keeping you safe. Also standard are VELO Hand Grips and a VELO Mountain Bike Seat on an Adjustable Aluminum Seat Post. A snap-on LED Light is also included. The Baja also has an Aluminum Rear Cargo Rack, a Drink Holder on the Handlebars, and a USB port to charge your devices. They thought of everything. All covered by a 1 Year Warranty and Lifetime Frame Warranty. All this makes X-Treme one of the best E-Bike manufacturers in the world. Introducing the X-Treme Baja Folding Electric Mountain Bicycle, one of the best e-bikes in the world.
