* Range is calculated from tests of a 187 pound rider on Eeyo 1s with a fully charged battery at an average speed of 14 MPH. Test course was les than 3% slope. Ambient temperature was 77°. Range may vary significantly depending on rider weight, speed and terrain slope. For example a 165 pound rider at an average speed of 11 MPH will have an estimated range 40 miles Sport and 55 miles Eco.
