Last updated 6th May 2019

Welcome to our Giant bike size guide. Most Giant bike models vary slightly in size, with a different minimum standover height (distance from the top tube of the frame to the ground, with around two inches of clearance between the top tube and your crotch when standing in-front of the saddle). If you’re in-between sizes, or unsure please just get in touch – we’re happy to help. You can also ‘try before you buy’ with our 1-2 day demos, or just pop into one of our stores for a quick test ride free of charge.
