How far can it go on a charge?

The 48V 26Ah battery is large for this class, so range should be well above typical 10 to 15Ah e-bikes. Real range drops with throttle use, rider weight, hills and cold weather.

Can I ride it with a dead battery?

Yes, but it is heavy. Fat tires, a big battery and a sturdy frame make it hard work to pedal unassisted, especially uphill.

Is the battery removable?

Yes. The battery comes out for charging, so you can bring it inside instead of running a cord to the bike.

What kind of terrain is it built for?

The 20 x 4.0 inch fat tires are meant for sand, snow, gravel, mountain roads and city streets. Full suspension helps on rough surfaces.

Is a 750W motor legal where I live?

Check local rules. Many regions cap e-bike motors at 250W or 500W and require pedal assist only, so a 750W bike may need registration or be restricted to private land.
