With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Hybrid Bike Sizing Guide

Hybrid bikes as the name suggests are a blend of a road bike and a mountain bike. The fit is a little more precise than a mountain bike, and a little less than a road bike, so you do see a mixture of t-shirt style sizing and measurements in CM and INCHES too. The fit will be more relaxed than a classic road bike though, and is designed to be a little more forgiving and upright.

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (13 - 14") 33 - 37cm
5'2" - 5'6" 158cm - 168cm Small (15 - 16") 38 - 42cm
5'6" - 5'10" 168cm - 178cm Medium (17 - 18") 43 - 47cm
5'10" - 6'1" 178cm - 185cm Large (19 - 20") 48 - 52cm
6'1" - 6'4" 185cm - 193cm X-Large (21 - 22") 53 - 57cm
