Electric Bike Size Guide

Finding the right size electric bike is key to enjoying a comfortable, efficient, and safe ride. At Bike Yard Online, we've put together this guide to help you confidently select a bike that suits your height and riding style. If the product page includes a specific brand size guide, we recommend using that first.

What Is a One-Size Bike?

Many e-bikes come in a "one-size" frame that fits most riders between 5ft 3" and 6ft 1". However, plenty of our customers fall outside this range and still ride comfortably thanks to adjustable seats and handlebars. If you’re unsure, our team is always happy to help.
