The E300S is the seated version of the E300 (hence the “S” tacked on the end of the model number). Going from an E200 to an E300 will get you more power, a larger deck, and 10″ pneumatic tires instead of 8 inch. Recommended for kids over 12 and adults, it is capable of speeds up to 15 MPH. Even though it is safe for adult over 200 pounds, if you are approaching that weight and you anticipate using it on hills, you may want to look at higher powered models. It performs well, even on rather steep grades for kids. Another feature not included on the E300 and not on the E200 and E100 are fully adjustable handlebars. Some buyers have complained that the battery depletes after 45 minutes, and then recharging takes 12 hours. (more…)
