The E100/E125/E150/E175 electric scooter family are all kick start models and are designed for ages 8 and up – with a kid-sized deck and frame. Traveling at speeds up to 10 miles per hour, the environmentally-friendly electric power engages a super quiet chain-driven motor. These models all run the same. The different models are based on the Retailer in which they are sold. We appreciate your interest in our products and if we can provide you any additional information, please let us know.
