We provide comprehensive size guides for all the major brands we stock, ensuring you get the perfect fit across every category, from mechanical hardtail bikes, full suspension mountain bikes to eMTBs and gravel models.

As a dedicated electric mountain bike (EMTB) specialist, run by riders we continuously strive to be the best in terms of:
1. Delivery | We offer free delivery* on all orders over £65. Bike deliveries are always carried out by a two-person courier service, ensuring your new ride reaches you safely and securely (*T&Cs apply).
3. Expert Bike Setup & Inspection | Every bike we sell goes through a full 26-point PDI (Pre-Delivery Inspection), completed by our Cytech-qualified mechanics. Electric bikes also receive an additional 9 specialist e-bike checks, including full diagnostics and software updates. Each bike’s suspension is tuned to your weight, ensuring it’s set up perfectly and ready to ride from the moment it arrives.
4. Safe & Secure Bike Packaging | We take the same care packing your bike as we do building it. Each bike is securely wrapped using a mix of bubble wrap and recycled materials, with the handlebars and front wheel removed for safe transit. Inside the box, you’ll find allen keys, your PDI checklist, accessories, and any chargers included. Once unpacked, your bike can be assembled and ready to ride in just 5–10 minutes.
5. DJI Avinox Certified eMTB Services | As early adopters of eMTB technology, we’ve invested in advanced diagnostic software and tools to support leading electric bike systems. Our team receives regular manufacturer-led training to stay up to date with the latest developments from DJI Avinox.

6. Frame Protection Options | As riders ourselves, we understand that your bike is more than just a purchase.. It's an investment.

These kits shield your mountain or electric bike from scratches, scuffs and chips, all while keeping your paint finish looking pristine.

‘Cannot recommend MTB monster enough! Ordered my bike on the Sunday and it was with me by Wednesday afternoon. Reliable 2 person courier service used as well. Bike went through a full PDI as well as the team setting up the tubeless tires as well which saved me the hassle. Great service and will definitely use again in the future.’
