Finding Your Perfect Bicycle Fit
Finding the right bicycle size is important for comfort, control, and an enjoyable ride. Bike sizing can vary depending on frame style, wheel size, rider height, and bicycle type.
Use our bicycle sizing charts below to find a recommended starting size for kids bikes, mountain bikes, and road bikes.
For the best fit, consider stand-over clearance, reach, and riding position. If you're unsure which size is right for you, contact Alaska Bicycle Center and our team can help you find the right fit.
