Our products have been tested for thousands of miles. We conducted our range and speed tests on flat, smooth, paved surfaces with no headwinds or tailwinds using an 170lb test rider and an optimally tuned bike. Any variables to this equation could cause a difference in actual results. Assembly and maintenance issues, such as low-pressure tires, misaligned brakes or wheels, or low battery power can make a significant impact on test results. We do not exaggerate or make false claims regarding our product specifications and test results. If you are experience any issues regarding product performance, please contact us and we will work together to determine the issue. It is important to conduct any speed tests in a safe controlled environment, as the product speeds can be dangerous in a public setting.
