If you are looking for a fat tire electric bike that has both power and speed which will allow you to tackle those steep terrains, you are in the right place.

The King is one of Aostirmotor'slatest models and comes with a powerful 1000W motor. Its 52V/15Ah battery is integrated into the 6061 aluminum alloy frame.

The range will vary by several factors, including total payload, surface conditions, and riding style, but on average you should expect about 31 miles of range per charge. The battery can be removed from the bike for remote charging.
