Frequently Asked Questions

Shipping and Returns

How much is shipping?

UK Mainland shipping bikes over £499 is free of charge, for orders under £499 we charge £29.95 for standard shipping.

We use DPD when shipping all our convensional bikes (i.e. not electric bikes) on an overnight service which includes full tracking and an hours timed delivery slot.

For further information please see our Shipping Policy.

When will you ship my order?

Orders placed before 12:00 on buisness days are usually shipped that same day.

Before we can ship your new bike, it needs to go into our workshop to be PDI'd (Pre-Delivery Inspected), during this inspection our mechanics will check everything is setup and ready to go - this can take a little time so on busy days or during sale periods it might take a day longer to process.

For further information please see our Shipping Policy.

How do I return an item?

If you need to return an item to us you can do so with 30 days of recieiving the item.

Simply follow the instructions on the paperwork enclosed with your order or visit our Returns Page for further information.

Returns are subject to our Refund Policy.

Is this bike in stock?

We only make available for sale products we have in stock, we do not remote warehouse products from suppliers as other stores do.

Our inventory is live except for bikes which are subject to up to a 24hr delay as our retail stores' inventory system is a bit archaic and requires a manual sync.

Have another question?

We have a Frequently Asked Questions page which also highlights our contact information should you need to contact us.

You can also contact us via Live Chat during normal office hours - the button is usually located in the bottom right of your screen.
