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

Hassle free returns

We hope you are very happy with your Windwave purchases. However if for any reason you are not completely satisfied, you have 30 days from the date on which the goods were received to return any item for an exchange or a full refund.

For any Returns or Warranty enquiries, you will need authorisation from our Returns Manager to be considered prior to shipping. Please contact hollie@windwave.co.uk for details. Hollie will arrange a return and an email containing a returns form will be sent to you. Please complete the form, attach a copy of your proof of purchase, and place them in with your product.

We recommend that you take your package to a post office and send via recorded delivery (or similar), as Windwave cannot accept responsibility for any loss or damage that may occur during transit. You are fully responsible for the item up until the time that it has been received by us. We advise that you email us the tracking number so it can be added to your claim for reference.

It normally takes us about 10 working days to process a return once the returned items have been received into our warehouse. Upon inspection of the returned product, Windwave will issue a refund or process an exchange. A return confirmation email will be sent to you once your return has been processed.

In the unlikely event that an item is returned to us in an unsuitable condition, Windwave reserves the right not to refund the item and arrange to send the item back to you at your expense.

Please note that we can only offer exchanges for a like-for-like product in a different colour or size.

Under the Consumer Rights Act of 2015 you have an early right to reject goods that are unsatisfactory quality, unfit for purpose or not as described, and get a full refund.

However, this right is limited to 30 days from the date you took ownership of the goods (this could be the date of purchase or the date the goods were delivered to you - whichever is later).

After the initial 30 days, you can't demand a full refund in the first instance, but you still have the right to a repair or replacement.

Refunds (if applicable)

Once your returned item is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund.

If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within 14 calendar days. If you paid for standard delivery of the goods, the cost of standard delivery will also be refunded.

There are certain situations where only partial refunds are granted (if applicable):

  • Books or other paper products with obvious signs of use;
  • Any item not in its original condition, which is damaged or missing parts for reasons not due to our error; and
  • Any item that is returned more than 30 days after delivery.

Late or missing refunds (if applicable)

If you haven’t received a refund yet, first check your bank account again.

Then contact your credit card company, it may take some time before your refund is officially posted.

Next contact your bank. There is often some processing time before a refund is posted.

If you’ve done all of this and you still have not received your refund yet, please contact Hollie at hollie@windwave.co.uk.

The all-new pbj is here!

The best thing in-between sliced bread.

The all-new pbj was redesigned from the ground up, now featuring an aluminum frame, new geometry and added features. The hydro-formed 6061 aluminum frame allowed us to build in the features that riders need for the level of riding today, unlocking extremely short chainstays and low standover height. The geometry and sizing has evolved to provide a quick and responsive feel, to help pump through corners and pull back off the steepest of lips. For riders seeking to find their flow riding dirt jumps, skate park, and pump track, look no further, the pbj is here to pump, bump and jump everything in sight. Now available in two sizes, short and standard, to best suit rider's needs.

2 sizes available

the ""short"" size was designed not only for shorter humans, but also to complement riders looking for a precise feel that allows for ultimate creativity. This size may just help you land that next rotation, boost out of the quarter pipe, or nail the trickiest of manual lines with a 377-395mm chainstay length and 395mm reach.

The ""standard"" size is best for riders looking to sharpen their skills at the pumptrack, or prefer a more stable geo for bigger jumps and higher speeds without sacrificing the playfulness of the short rear end. This size has the same 377-395mm chainstay length as the short, and is paired with a 420mm reach.

Hydro-formed 6061 aluminum

the all-new new frame is made of hydro-formed 6061 aluminum, known for its high strength to weight ratio, and smooth look. It's both simple and refined, all while keeping it light. The design keeps things compact with a low standover height, giving you a feeling of effortless control with room to move. The clean lines create a modern vibe with a laid-back, minimalist style that fits in at the dirt jumps, skate park or pumptrack.

Chain tensioners

integrated chain tensioners make it easy to fine tune your chain tension and keep the rear wheel aligned in your frame. These work with all 10x135 hubs and are easy to adjust with the tool-less design.

Cable routing

internal or external cable routing allows you to have it your way. Run your brake cable internal for a clean and tidy look, or external to make brake swaps simple as well as give gyro capability.
