Pre-Order

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!

Pre-Launch

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.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

FAQs
What happens if my item is faulty?
In the unlikely case that your item has developed a fault please contact us at [email protected] or call 01206 699311.
Can I cancel my order?
Yes, if we haven't shipped the order yet just contact us and we should be able to cancel the order for you. If it has already been shipped please refuse delivery, this will allow them to come back to us.
Can I return a bike?
We know that sometimes a short ride is what it takes to know if a bike is suitable. However, to be eligible for a full refund, the bicycle and its accessories must be clean and not display any damage or signs of wear, exceeding that which could be expected to establish that the bike is not suitable for the intended purpose.
I am returning a bike, can it be collected from home?
Yes, our courier collection fee is £30. However, you must use the original delivery packaging - if you do not have the original box, a new one will be sent at an additional cost of £60.
