Big Trail 500

In 2019, a few UK customers met Merida's MTB Product Manager Rey and over a few beers and together hashed out a wish list for the perfect UK specific hardtail mountain bike - a trail focussed 29er with 140mm fork, 1 x transmission, Boost standard bolt through axles and a dropper post. Then it was over to Rey, a very handy rider himself, to develop the ideas into a workable production bike.

That wishlist became a family of models of which the Merida Big Trail 500 is part of - featuring a slack enduro inspired 65.5° head angle and a 140mm fork delivers a fun confidence-inspiring bike. The long reach and short seat tube give plenty of space to manoeuvre on the bike and a really low standover height.

Merida has used long dropper posts to achieve a short seat tube, an advantage of this geometry is that depending on your riding style, most sizes will work for most body sizes.

The only question is if you want to go crazy fast or super agile? For speed take the longer size, for agility take a shorter size.

BUILT-IN VERSATILITY

While clearly a trail loving long-travel hardtail, the new BIG.TRAIL also offers built-in versatility through the hidden rack, fender and kickstand mounts in case you like to turn the BIG.TRAIL into a ‘SUV’ commuter.

DOUBLE BOTTLE

Ability to fit two water bottles into the frame without making the bottles difficult to reach. Perfect for long marathon races and extended trail sessions.

TYRE CLEARANCE BIG.TRAIL

BIG TRAIL rolls on 29er wheels and has tyre clearance for up go 2.5" trail tyres. The combination of 29er wheels and 2.5" tyres offer plenty or corner and climbing grip, while the big tyre volume and the 29er 'rolling over ability' give trail hardtails extra comfort and stability.

TRAIL MOUNT

The new 'Trail Mount' is positioned underneath the top tube/seat tube junction and these ingenious fixing points makes fitting an additional tool or a pump a breeze. The 'Trail Mount' offers a real advantage if you prefer to keep the weight off your back or if you are heading out for an extra-long outing where you might need to carry additional gear.

INTERNAL CABLE ROUTING

Merida features internal cable routing on all models. Cables are routed through the frame, entering and exiting through smooth sockets. Only a clever system for their internal guiding and fixing guarantees reliable and rattle free routing, whilst the cables are protected from moisture and dirt and gives the bike a cleaner look.

MODERN TRAIL GEOMETRY

A long reach, paired with a slack 65.5° head angle and a steep seat angle makes BIG TRAIL a solid descender even when the trail is littered with roots and rocks, while maintaining impressive climbing abilities, due to the central seating position over the bottom bracket. The extra short seat tube and low standover hight help to create lots of space to manoeuvre the bike when the trail gets demanding but also allow for long travel dropper posts.

BOOST TECHNOLOGY

All BIG TRAIL models offer Boost technology at the front and rear. The shallower axle standard of 110 mm (front) and 148 mm (rear) allows for a wider spoke angle, resulting in a stiffer and stronger wheel, hugely beneficial on these bikes given the impacts they endure.

Model Technologies

SMOOTH WELDING

Sometimes called ‘double pass welding’, a second pass over the weld gives a clean organic look to the frame. At first glance, you will be convinced it is carbon.

INTERNAL CABLE ROUTING

Cables are routed through the frame, entering and exiting through smooth sockets. The bike looks neat, whilst the cables are protected from moisture and dirt.

X-TAPER HEADTUBE

Merida's X-Tapered headtube offers the space for a tapered fork to be fitted. Tapered forks offer superb stiffness and precise and deliver confidence-inspiring steering.

DOWN TUBE EXIT

Ensures that internally routed cables and wires can’t move freely and remain easily accessible for servicing.

TFS - TECHNO FORMING SYSTEM

Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with an internal metalcore.

RACE LITE 61 ALUMINIUM

Merida uses a minimum of 6061 aluminium. The payback is that it’s possible to make lighter and more advanced frames buy using additional heat treatment and double-butted wall thicknesses to produce light and stiff frames.

Whilst we do actively try to keep on top of all the details, manufacturers do occasionally change model specifications so anything detailed above is subject to change.

** Some stock may come with an equivalent Tektro HD-M275 hydraulic disc brake setup due to a shortage of parts from Shimano following the pandemic.

Bike Delivery

In Stock

Unlike many of our competitors, we only make available to purchase online bikes we actually have in stock here in our store − we don't ever remote warehouse or SIM feedstock with multiple day delays.

Furthermore, we aim to have all our bikes pre-built and available for immediate dispatch or for in-store collection, once you have ordered a bike from us one of our mechanics will package your bike into one of our custom-built boxes.

These extra-large boxes allow us to ship most bikes fully assembled but before we do so our mechanics will carry out a PDI (pre-delivery inspection) on the bike to ensure that before it's prepared for shipping everything is set up correctly, e.g., brakes, gear indexing etc.

Pre-Built Bikes

We ship our bikes pre-built and fully PDI'd so upon receiving your new bike you will simply need to just take your new bike out of the box, turn and tighten the handlebars and fit one of the pedals (if your bike comes with pedals). In some instances, such as for road bikes, you may also need to attach the handlebars as they're too wide to simply be rotated so they'll be secured to the side of the frame with zip ties.

This process does vary from model to model as bikes come in all shapes and sizes but this is the case for nine out of ten bikes we deliver - if you ever have any questions about this please don't hesitate to contact us.
