Baja Folding Ebike Description

The Baja 48 is unlike any other ebike on the market today. It combines a full-size all aluminum folding frame, with full-suspension, in a powerful electric bike.

The 48V/10.4Ah battery is integrated into the frame, and is removable for remote charging. This battery powers the 500W Bafang rear hub motor, which can be operated using the left-side thumb throttle, or the 5-level pedal assist system (PAS). The Baja has a maximum assist speed of 25 mph, making it a great bike for city riding.

The Baja can be ridden like a conventional bike, using the 9-speed Shimano Atlus drive train.

    Really Good Ebikes

    Awesome review. Thanks you.


    Good service from ReallyGoodEbikes

    Unfortunately, I was not able to go on a ride with the X-Treme Baja 48V Folding eBike as it already arrived damaged from the warehouse :-( So I'll only rate the support received from ReallyGoodEbikes in terms of communication with the manufacturer. Steve did anything to get the issue resolved.

    Sorry for all the hassles. Thanks for the honest review.


    Unique and Fun Ride

    I looked everywhere for a full-size electric bike that folds, but they are pretty rare. So I was super excited to find the X-Treme Baja, which is perfect for my needs. Not only is a full-size folder, but it also comes with rear suspension, also unique. I ride almost everyday, and I'm very happy with my new Baja. Thanks Steve.
