- 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 Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier

Will my bike have a curved top tube?
Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.

Fit for every rider
Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you're on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value
Marlin looks and feels great. It's packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Shimano CUES
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano's new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.

A better way to produce aluminium
Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Shimano LINKGLIDE
LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting - along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.

We do not currently offer to ship bikes purchased via our website, these must be collected from our store. If you see a bike that you are interested in and are unable to collect from us then it may still be worth getting in touch with us to explore further options.


Arrangements and order processing times on new bike purchases

Bikes purchased via our website will be made ready for store collection. This can take a few days depending on where the bike is located. Some bikes will need to ship from a supplier but if this is the case the expected lead time for delivery to us will be displayed on our site. We also hold stock at an off-site storage location and transfer can take a day or so. When we have the bike it will be scheduled for assembly and safety checks with one of our CYTEC mechanics. Once this is complete we will send a final confirmation that the bike is ready for collection and you can then visit the store to pick it up.

With bike purchases, a member of our team will usually contact you prior to processing to check sizing and other details. For bikes in our stock the process from order to collection usually takes 3 or 4 working days but can be quicker sometimes or longer if the bike is shipping to us from a supplier. A member of our team will be able to give you more information if required.


Store collection

Once your new bike is ready for collection we will get in touch with you to arrange a convenient time for pickup. Collection is from our store at 65 North Parade, Aberystwyth. When you come to collect we may ask for you to present proof of identity for security reasons. A member of staff will check size and personal adjustments like saddle height and can provide advice on care and service arrangements so please allow a little time for the handover process.
