With a tire capacity of 45mm, it’s ready to go anywhere, fast.

Your new bike can be collected from our Experience Centre or securely shipped to you by Next Day Delivery.

We have developed a custom bike box that allows us to safely ship bikes with very little reassembly required. Rather than sending your bike to a shop all you have to do it put the wheels on and insert the seatpost. We will even set up and mark your saddle height so you can ensure your new bike is set up and ready to ride.
