Size Guide

What size Saracen bike should I choose? It’s probably one of the first questions you’ll need to answer before buying your new bike – here we are going to provide all of the answers. 

Most Saracen bikes come in sizes small, medium, large and extra large. Typically, the taller you are, the bigger the size you choose. Every bike page on our website has a sizing chart to try and help you to pick the perfect bike.

This sizing applies to our Mantra, Zenith, Ariel 30/60/80, Myst AL and Ariel E-Bike ranges.


On our Ariel 30 and 60 models, we specify a full 29er setup on the size large and extra large models. The small and medium models use the mullet setup, with a 29er wheel up front and a smaller 27.5-inch wheel at the rear.

However, every Ariel 30 and 60 comes with a pair of links allowing you to switch rear wheel size if you want to. All you’ll need to do is install the link and buy a new rear wheel and tyre.


Our Myst range uses a completely different sizing approach called Factory Rider Fit.

This has been developed in conjunction with the Madison Saracen Factory Racing Team to provide the fastest bike on the hill.

Our latest Mysts all feature a mullet setup - reflecting the direction of our team.



Our Amplitude bikes only come in sizes medium and large. These are dirt jump specific bikes and as such are built – or should we say overbuilt – for the purpose. You won’t want to be riding anything other than sweetly sculpted trails on these.

Our medium size is best suited for riders up to around 172cm, while our large provides a bit more room to move around the bike. Of course, you may just prefer the stability of the larger size, which is another way to look at it.

If you’re still uncertain which size is right, please contact us, or message us on Facebook where we will be happy to help.
