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

Please be aware Click & Collect orders may take some time to fulfil. We advise not to travel to your chosen store until you have been notified that your order is ready for collection.

Spread the cost of your new bike, helmet, safety equipment and accessories paying via instalments being taken directly from your wage. The payments for the Cycle To Work scheme are taken out of your gross wage and your Tax & NI contributions are then worked out based on your new lower gross wage which is how you save money on your new bike and equipment.

At the end of the time period specified with your Cycle To Work scheme you then have the option of buying your bike or to continuing to use it while you work for the company. If you decide to purchase the bike, the balance you owe will be based on a percentage of how much the bike was worth at the time you took out the Cycle To Work scheme.

We know how eager you'll be to jump on your new bike and hit the dirt or tarmac, so we give you everything you need to get you set up quickly. For full instructions on how you're bike will arrive and what you'll need to do, visit our How Our Bikes Are Built page
