Is the Xkj 750W e-bike worth it?

Only if the low price matters more than reliability. Its 2.6-star average from 73 ratings suggests a real risk of defects and poor support. A used name-brand e-bike is often the safer buy at this price.

How fast does it go and how far on a charge?

The motor is capped at 20 MPH. Range is about 20-25 miles on throttle alone and 40-55 miles with pedal assist, depending on rider weight, terrain and assist level.

Is the battery removable?

Yes. The 576Wh lithium battery is built into the frame but removable, and it is described as waterproof, shockproof and anti-theft. Charge it on or off the bike.

What size rider fits it?

It uses a 26-inch frame and 26-inch wheels, aimed at adults of average to taller height. Check the standover height before ordering, since a steel frame this size is not light.

What comes in the box?

The listing mentions keys for the battery lock. Expect the bike largely assembled but needing handlebar, pedal and front-wheel fitting; confirm the charger and tools are included before you buy.
