The "standover height" is one of the most important measurements to consider when determining whether or not an ebike from Rad Power Bikes will fit your unique body proportions.
The standover height is the distance from the top tube of the frame to the ground, measured from just in front of the seat. This is where you would be straddling the bike frame, ideally with your feet flat on the ground. As long as you have around an inch of clearance between the top tube of the bike frame and the base of your torso, you should be able to ride (and come to an abrupt stop) safely.
You can determine the clearance by comparing the standover height of a bike to your internal leg length, or inseam.
Photos of the standover height of each ebike from Rad Power Bikes can be found under the "sizing" tab on each bike's product page. The standover heights for our different models* are also listed here for your convenience:
RadRover -- 30.5"
RadCity 16" frame -- 29"
RadCity 19" frame -- 31"
RadCity Step-Thru -- 20"
*These measurements are for 2018 models. Previous model standover heights may vary slightly.
