With a step-over bike, you can be sure that your bike is made with a tried and true design and will last you for many miles to come. Additionally, step-over bicycles are also generally designed to be ridden through multiple types of terrain. Step-over bikes are sometimes made with lightweight materials because the frame design ensures its strength. This means that such bikes be able to reach higher speeds with far less energy exerted. This isn't necessarily an issue with electric bikes, as both the step-thru and traditional designs can reach speeds close to 28mph depending on the model.
