Please note that information regarding the expected range on a single charge on one of our Glee Bikes is an estimate, not a guarantee. There are many factors that contribute to actual, real-world range for an ebike battery such as age of the battery, temperature, level of assist, speed, payload, and terrain. Given the right conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range. GLEE Bikes Inc reserves the right to use substitute parts, material, or equipment of equivalent quality and value that meet Glee EBikes Inc strict standards.
