Giant Bikes Size Guide

Welcome to our Giant bike size guide. Finding the correct bike size is vitally important for efficiency, comfort and, of course, the enjoyment of riding your bike. The correct size of bike will put you in an optimum position so you get the efficiency, comfort or manoeuvrability you require depending whether you are looking at a road bike, electric bike, or mountain bike.

We stock a wide variety of Giant Bikes and Giant Electric Bikes in all different models and sizes. We also stock a massive range of the female-specific Liv Bikes and Liv Electric Bikes with most models available for test rides. We have recently introduced our dedicated Giant Store Edinburgh, located in Hamilton Place, Stockbridge that stock Giant and Liv bicycles, clothing and accessories.

Please Note: Size charts are meant as a guide only and the best way to find the right bike sizing is to sit on the bike and test it out. If you're in-between sizes, or unsure please get in touch - we're always happy to assist.

A note on mountain bike sizing

Mountain bikes are trending towards a more flexible sizing system where you have a greated degree of personal preference. Opting for a larger frame will increase stabilit in a straight line while choosing a smaller frame, with a shorter top tube will give more manoeuvrability on technical trails. This is something we will happily discuss if you were to call our online department or pop in to any of our 6 stores in Aberdeen, Leeds, Newcaste or one of the three in Edinburgh - Bruntsfield, Canonmills or, as previously mentioned, our new Giant Store Edinburgh on Hamilton Place, Stockbridge.

We hoped this giant bike size guide has helped you decide on the perfect frame size whether you are on road or off road, a leisure cyclist or chasing maximum performance.
