- 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.

GET UP TO 39% OFF THE COST OF YOUR NEW BIKE: HAPPY CYCLE TO WORK DAY

The UK’s Cycle To Work Scheme has been in place for over 20 years now, offering fantastic discounts to tens of thousands of riders.

The Cycle To Work Scheme, is offered through many thousands of employers in the UK and applies to bikes of all types, whether it’s road, MTB or hybrid, and that includes e-bikes too.


About the Cycle To Work Scheme

Introduced in 1999, the scheme aims to encourage employees to commute on their bike for environmental, traffic congestion and health reasons. It also enables companies to demonstrate that they’re looking after the wellbeing of their people.

Obviously, you’re supposed to use the bike for commuting – and we are massive supporters of getting to work this way – but it’s fine to buy a bike that’s built for the trails. Your employer owns the bike until you pay the final ownership fee, which is based on the “fair market value” of it at the end of that period.

As well as your new bike, you can use the scheme to buy accessories, such as helmets and bags, though these have to be ostensibly for your commute. So, no full face masks, for example. If you don’t have a lock, we strongly advise that you get one along with your bike as you’re liable for the Cycle To Work payments, even if it gets stolen while you’re paying it off.


How does the Cycle To Work Scheme work?

This is a salary sacrifice scheme for people aged 18 and over where the monthly payment for your bike is taken out before tax and National Insurance are deducted. Because your contribution is taken before tax, you pay off more per month for less. So, for a bike costing £1,200, £100 is taken from your salary every month but it only costs you £68 because the other £32 would have normally gone to the tax man, right? So, you pay 12 instalments of £68 and a final ownership fee of £300, totalling £1,116. If your salary puts you in the higher tax brackets, you actually save more but you get the gist.


I’m interested. What do I need to do?

Firstly, find out which scheme your employer is enrolled in and therefore where you can buy your bike from. We work with a number of Cycle To Work providers, including cyclescheme.co.uk, cycleplus and Bikes for the NHS.

Then you need to speak to your HR department and request a certificate, bring it to us and we’ll redeem it against the cost of your bike and accessories. The salary sacrifice commences from your next pay packet.

To get a bike on the scheme, your employer needs to sign up to a provider. If they’re unsure about how to do this, send them to us and we’ll help.
