Frame Size

E-bike frames range in size anywhere from 15 inches to 22 inches. An e-bike’s frame is not adjustable, so you should take the time to find the right size for you because you won’t be able to go back. Some e-bike manufacturers also measure frames with size designations such as XS, S, M, L, etc.

Handlebar Height and Size

Your arms should be shoulder-width apart while holding onto your bike’s handlebars. Wider handlebars can help you achieve easier breathing, while narrower handlebars can help with aerodynamics. You should also find a bike with adjustable handlebar height so you can customize your comfort level.

Seat Height and Size

Insider Tip

You should also find a bike with adjustable handlebar height so you can customize your comfort level.

The best electric bikes offer an adjustable seat height to help with maximum comfort. To get the right height, sit on your bike with one foot on a pedal at the lowest position. Your knee should be slightly bent, allowing for maximum downforce and minimum knee strain. Additionally, eBike battery maintenance is also essential if you’re looking to get the most out of your eBike.

Quick Sizing Guide

The fastest way to find the right size e-bike is by choosing a frame size based on your height. Use the following chart for a quick and easy measurement process:

Your HeightBike Frame Size
4’11” – 5’3”13” – 15”
5’3″ – 5’7″15” – 17”
5’7″ – 5’11”17” – 19”
6’0″ – 6’2″19” – 21”
6’2″ – 6’4″21” – 23”

Advanced Sizing Guide

If you plan on getting serious about biking, you’ll want to be 100% sure you get the exact right fit. Using your leg inseam measurements, you can be sure you’re getting the right bike. To measure your inseam, stand with your feet 6 to 8 inches apart and measure from the floor to your crotch. The calculation requires measurements to be in centimeters and not inches. After writing down your measurements, perform the following calculations:

  • Commuter/Cruiser: Your leg inseam (cm) x 0.685 = bike frame size (cm)
  • Mountain: Your leg inseam (cm) x 0.66 = bike frame size (cm)
  • Road: Your leg inseam (cm) x 0.70 = bike frame size (cm)

To convert centimeters to inches, simply divide the final number by 2.54.
