Fitting a hybrid bicycle is a matter of ensuring that both the frame and the inseam are the correct size for your height and weight, as well as your leg, arm, and torso length. If you plan to buy your ride from a professional bicycle shop, the salesperson will spend quite a bit of time ensuring you are fit correctly. If, on the other hand, you plan to buy a secondhand bike from a private seller, it's useful to know how to measure the bike yourself for a correct fit.

What's in a Hybrid?

Hybrid bicycles have been around for years and were conceived to fall somewhere in between a mountain bicycle and a road bike, combining the durability and ruggedness of the former with the lighter frame of the latter. Stockier than a road bike, they perform well on light off-road trails, while still having quite a bit of get-up-and-go on regular roads. While they can't tackle extreme terrain and weather conditions like a mountain bike or ride as fast and nimble as a skinny-tired road bike, hybrids are a good choice for those who don't have space or the finances to afford both a commuter and a recreational bike. Hybrids will get you to work quickly and smoothly during the week, and allow you to enjoy a bit of off-road fun on the weekends. 

The Importance of Fit

Bicycle riding is one of the best ways to get and stay in shape, but so many people give up after just a few rides. Either their hands fall asleep or they wake up the next day with shooting pains in their neck, shoulders, and back. When this happens, an improperly fit bike is most likely the cause. That's because bicycles are not one-size-fits-all. Everyone's body is different—even people who are the same height and weight will have differences in arm, torso, and leg lengths.

That's why it's imperative to get fit for the right-sized bike. Not only will it prevent numbness and injuries, it will reduce rider fatigue and ensure a more comfortable and productive ride.

Measuring Hybrid Bicycles

Like most bicycles, hybrid bikes are generally measured by frame size, which is the distance in inches from the center of the crank to the top of the frame at the seat tube. The sizing of hybrid bikes is comparable to the sizing of mountain bikes, which means they'll run a couple of inches smaller than a comparable road bike.

Knowing your height and inseam measurements are all the information you need to determine the proper frame size fit for a hybrid bike, though inseam is the more important measurement going in because leg length is more relevant than torso size. Of course, the ultimate test of a hybrid's size and fit is the practice ride—many shops will allow you to take a comparably sized "loaner" home for a few test rides.

While nothing beats a professional fitting while pedaling your potential new bike on a trainer, the following is a good guide to get you started in your search—and you can also use it to gauge whether or not a used bike will be a comfy ride.​
