- 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.

The suggested rider height is the recommended height range for this size of bike as stated directly from the manufacturer for this specific model - It is the most reliable sizing metric.
However, please note that although these height ranges are recommended by the brand, they may not be accurate for everyone. Factors such as inseam length and preferred riding positions can affect the appropriate sizing.
If you see the label "not confirmed," it means either this brand doesn't provide recommended height ranges, or we were unable to locate it for this model. In these cases you you can refer to our general sizing guide
Most buyers never see the bike first
You can collect from the seller if you'd rather. But the bike is wherever the seller is, and you might be hundreds of miles away, so most people have it shipped and rely on us instead of a viewing.

How does buyer protection work?
Our Buyer Protection policy is in place to prevent any mis-selling on the platform and ensure you get exactly what you paid for! If the bike arrives "not as described", such as there is damage that wasn't disclosed in the listing, or the specifications are wrong, then you can return it to the seller free of charge. Simply contact our support team and we will arrange this for you. To learn more, please read here.
What if the bike doesn't fit me?
Frame size is the one thing photos can't tell you, so check the fit details on this listing against your height, and use the size guide if you're between sizes.
Buyer Protection covers a bike that isn't as described; it doesn't cover a change of mind on sizing. If you're unsure, message the seller for the stack, reach and standover before you buy.
Can I get the bike serviced before it arrives?
Yes. Add MNB Verify & Service at checkout and our mechanics inspect, service and safety-check the bike before it ships: brakes, gears, tyres, drivetrain and frame.
You get a written report of what was checked and anything replaced. It's the closest thing to seeing the bike yourself.
How do I know the specs are accurate?
The technical specifications are the manufacturer's factory list for that model and year, not a record of what's fitted today. Sellers commonly change wheels, saddles and finishing kit.
What the seller has actually changed is in the Upgrades and damage sections, and every listing is reviewed by a person before it goes live. If the bike arrives materially different from the listing, that's a Buyer Protection return.
