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

Returns & Exchanges Policy Summary

We offer a 14 day returns period from the date of receipt.

It is your responsibility to ensure that the item is returned to us safely and securely, we suggest that you use a recorded postal/courier service. Please ensure that the service you use covers the value of the goods in the parcel.

We are unable to accept returns where the goods or packaging has been used, lost, damaged or is otherwise not in the condition you received it in. Bikes must be returned in a securely packaged bike box.

If you would like us to arrange a collection via courier, then we can do so at a cost of £50. Should you fail to be present for an arranged collection, you will be charged £20 to rebook.

We will refund up to £10 for private postage of faulty or damaged items.

If you would like to exchange an item, we will happily send out a replacement product once the original has been returned.

Refunds will be made to the original payment method - this may take up to 10 days to appear depending on the method of payment. Initial shipping costs are non-refundable.

We are unable to offer a refund without proof of purchase.

We cannot accept returns without a completed returns form.

Signing for delivery receipt of items that have clearly been damaged by the courier is the responsibility of the receiver.

Items that are damaged during a return as a result of inadequate packaging will be declined and returned to you, or charged for.

Faulty Goods and Warranties

If the item that has been received is faulty, damaged or not as described then we will cover the cost of return postage (up to £10) and offer a refund or exchange. In these instances, we would always recommend using our own shipping services.

Important information to note about returning faulty, damaged or not-as-described items:

Pauls Cycles issue no warranties, all warranties are issued by manufacturers. For this reason, we may need to send your goods to the manufacturer for inspection before taking any action. Please see the relevant manufacturer's website for full warranty information.

Only products that are faulty, damaged or not as described by ourselves are eligible for returns/exchanges. If damage has been caused through wear and tear, improper care or some other factor beyond our control then it will not be covered.

Once a faulty item has been used, or if the packaging has been damaged it can still be returned to us, however, we - and the manufacturer - reserve the right to offer a repair, replacement or partial refund.

Remember it is your responsibility to ensure that returned items are packaged appropriately - any damage caused in transit [as a result of inadequate packaging] will be chargeable.

We cannot accept any cycle warranty claim or return for incorrect pedal fitment or damage to crank arms caused by incorrect pedal fitment as described in the helpsheet supplied with all of our bikes.

If the wheels on the bike you've ordered become untrue through use, or the gears need readjustment after initial use, this unfortunately not covered under warranty.

Trek Marlin 5 Gen 3 Hardtail Mountain Bike Purple Flip To Trek Black Fade

Season:2025

Brand:Trek

Code:40773

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail.

It features a trail-savvy frame with a suspension fork, 9-speed Shimano CUES shifting and mounts for a rack and kickstand that make it an ideal choice for trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.

Features:

  • The Marlin Gen 3 gives you serious trail capability, with big tyre clearance and slack, confidence-boosting geometry that keeps you stable from singletrack to city
  • Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • Its ThruSkew system is safer, simpler and stronger, plus it makes removing the rear wheel easy for flat fixes in a hurry
  • Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending
  • Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount
Please note: Not all bikes come with pedals. It's always best to check specification before you place your order. Shop our Pedal collection.

Size Guides are a great way to help you find the right bike, but we always recommend visiting our store to view and sit on the bike in person where possible or speaking to our advice team.

This Size Guide is based on an average build, if you have shorter arms or longer legs for example you will need to consider this when purchasing a bike. If you are between sizes, we always recommend sizing down as a smaller bike can be made bigger with adjustments. Stem length, Saddle height, Handlebar width and even Crank length can be changed to achieve the ideal riding position. See here for our general bike sizing guide.
