You’ll love the Baja. Powered by a compact lithium LiPo4 48 V 10 Ah battery pack and a 500W Bafang high-torque, zero-resistance clutch motor, this folding mountain bike checks all the boxes. Hand-welded from aluminum and totally rust-resistant, it features an Altus Shimano nine-speed gear and shifting system, aluminum rims with quick-release and waterproof quick-disconnect axels, Suntour XCT front suspension, and KS rear shock suspension.

The Baja’s been tested on 5-7% mountain-grade inclines continuously at 18 mph and has a proven track record of being able to slow down efficiently for hairpin turns. The bike comes with front and rear Tektro disk brakes, VELO hand grips, and a VELO mountain bike seat.

A Smart E-Bike

The Baja features a King Meter five-speed smart power assist system (SPAS), and its electronics are fully controlled by the rider via the bike’s LCD screen. Attached to the handlebars, this screen also displays your speed, distance, and battery life while you ride. And thanks to a feature that lets you select your ride’s power consumption, it’s twice as efficient as non-smart-assist e-bikes.

Top-of-the-Line Components

All the components used to create the X-Treme Baja come from the top bike manufacturers. Like Suntour XCT front-end suspension and KS rear shocks, Tektro disk brakes, Kenda tires, a King Meter SPAS, Velo hand grips and seat, and an Altus Shimano nine-speed shifting and gear system.

Convenient, Easy-to-Remove Battery

The bike’s battery comes in a lightweight, 48 V, 8-amp LiPo4 sealed pack. The batteries are stored inside the frame; they can be conveniently accessed when the bike is folded. You’ll find the pack is easy to remove and charge. There’s even a key lock for added security.

    WOW! A full size, full suspension folder, WHAT A FIND! I am so excited can’t wait to get this bike so I can get out and ride. I only wish I did not have to wait so long for it.

  2. Andres G.

    Totally worth it! It’s fast! Battery lasts long! Looks like an actual Bike even with the foldability advantage!
    Only “downside” I may think of is that when you fold it It’s hard to lift it or hold it folded as it’s a bit heavy. But really is the best foldable, fast and great looking electric bike I could find!!

    Finally, I got my hands on this bike! I’ve actually been saving up for this for some time now! The smart PAS really helps. My old electric bike only had one power assist setting and I didn’t always need that much help. This one has five settings, so I can fine tune it depending on how I want to ride. Folds up quick. So cool! Awesome buy, I will definitely recommend the Baja to my friends!
