eBIG.TOUR

MOUNTAIN BIKE TREKKING AT ITS BEST

VIEW ALL BIKES

The eBIG.TOUR EQ combines the best of two worlds - from the outside a mountain bike, but a trekking bike at heart. Featuring a frame which is based on the eBIG.NINE and a mountain bike fork as well as MTB tyres, the bike provides a more comfortable riding feeling than a trekking bike, but at the same time, comes equipped with fenders, carrier and lights. The bike is the best way to get from A to B or make your trekking tours more enjoyable, but with the added knowledge that you could take the MTB trail as a shortcut if you want. The new eBIG.TOUR EQ features in-tube battery technology, and all models are powered by the new EP8 power unit from Shimano STePS.

INTENDED USE

The MERIDA eBIG.TOUR EQ is the perfect e-mountain bike hardtail for people who are looking for a trekking bike with all its benefits of a comfortable and upright seating position, fenders as well as lights and carrier, but don’t want to miss out on the comfort and safety a 100 mm mountain bike suspension fork and wider 2.2" MTB tyres can offer. The eBIG.TOUR EQ is ideal for relaxed cycling tours, day trips or for commuting in any weather condition.

KEY COMPONENTS

Energy Guard Twist

The MERIDA ‘Energy Guard Twist’ is a two-component battery cover, which offers easy and fast access to the battery while protecting it from outside impacts. The new twist-lock mechanism that is located at the top end of the battery cover allows tool-less locking and unlocking of the protective internal battery cover.

Certified system weight

The system weight of a bike is the combined weight of bike, rider and additional luggage. The allowed system weight for the eBIG.TOUR EQ is 140 kg. As an e-bike is already heavier than a regular bike, and as it also makes it easier to transport larger amounts of luggage, it is imperative to certify a higher overall system weight. All MERIDA e-bikes, as well as all used componentry, go through a rigorous and e-bike specific testing schedule which mimics the higher forces and strains to guarantee the rider the highest level of safety. 

Shimano battery (integrated)

Powerful internal lithium-ion battery that offers 630 Wh, charges up from 0-100% in 6 hours (when EC-E8004 charger is used) and retains at least 60% of its original battery capacity after 1,000 charging cycles. The aluminium cased battery is extremely compact, allowing us to seamlessly integrate it into the downtube for ample space for the rear shock, added water bottle fixing points and plenty of top tube clearance. It has a waterproof design and is impact and vibration resistant.

Optimised centre of gravity

Based on the central position of the battery in the lower part of the down tube and the low position of the Shimano motor, we were able to achieve an optimum centre of gravity. The low and well-positioned centre of gravity provides the bike with outstanding riding characteristics which are extremely important in particular when fully loaded.

Excellent frame stiffness

The outstanding frame stiffness also has a strong influence on the riding characteristics of bikes with an integrated battery. The tapered head tube, with the large 1.5" to 1.5" diameter, the 34.9 mm (internal diameter) seat tube, the cast motor bracket as well as the 148 x12 mm rear through axle all contribute to achieving a safe and precise riding experience.

Water bottle mounts

The eBIG.TOUR EQ frame offers the possibility to fit a water bottle or further accessories like a lock or pump in two different positions. One is on the top of the down tube, while a second is below the top tube. This gives the rider, besides the possibility to mount bottle cages, the option to mount for example a folding-lock or pump bracket.

MERIDA EXPERT CT adjustable stem

Our in-house components are designed and constructed with the demands of the individual bike type in mind. The MERIDA EXPERT CT stem is fully adjustable, allowing the rider to find the ideal angle for the perfect seating position. Furthermore, it surpasses all MERIDA e-bike specific tests which are more demanding than the legal requirements. All components are tested and certified for a system weight of up to 140 kg. In combination with a specifically designed headset, we are able to run certain cables directly from the stem into the frame, reducing cable clutter and preventing cable kink.  

MERIDA EXPERT TK saddle

With the new generation of MERIDA trekking saddles, the focus was clearly on comfort. The riding position on a trekking bike differs mostly in the more upright sitting position, which means that there is more pressure on the saddle. That's why trekking saddles are a little wider and also have sicker padding compared to sportive saddles. Another nice feature at this saddle is the V-Mount interface, which allows you to mount accessories directly on the baseplate of the saddle.

MIK HD rear carrier with Spanninga rear light

The entire eBIG.TOUR EQ range comes equipped with the MIK HD rear carrier with a load capacity of 27 kg. The rear carrier is child seat authorised, allowing you to turn the eBIG.TOUR EQ into the perfect family vehicle. It also features the integrated Spanninga rear light, for maximum visibility. Similarly to the front light, the rear light is also charged by the main battery and can be operated from the Shimano STePS display.

Lezyne front light

The 2021 eBIG.TOUR EQ features the new Lezyne Power Pro front and USB rechargeable rear light. The front light attached securely to our stem clamp plate, keeping the light perfectly fixed to the bike without cluttering the cockpit area. It draws its power from the main battery and can be easily operated from the Shimano display unit.

Hidden kick-stand mount

The 2021 eBIG.TOUR EQ frames offer hidden attachment points for a kick-stand underneath the chain stay, perfect for making the bike more versatile if used as an ‘SUV’ bike.

Satellite charging port

The satellite charging port can be found above the motor at the down tube/seat tube junction, perfectly protected yet super easy to get to for when the battery is charged within the frame.

RIDE THE REVOLUTION

SHIMANO EP8 DRIVE UNIT

For 2021, the entire eBIG.TOUR EQ range will be powered by the new EP8 motor from Shimano. The new power unit brings a long list of upgrades and changes to the table that will elevate our eBIG.TOUR EQ to the next level. The EP8 delivers a maximum power output of 85 Nm, which is an increase of 15 Nm from the E8000 unit. This will improve the performance on extreme terrain as well as lift up the other support levels, making them universally more cable and more fun to use. Paired with the new 630 Wh battery, the new EP8 system delivers a huge range extension, making it easier to cruise for longer or do more runs. 

Further to that, the new power unit has lost approx. 300 g in weight, has further improved its heat-resistance, allowing the rider to go harder for longer, has become quieter and smaller and has managed to achieve a 36% reduction in drag, making cruising about the cut-out speed even easier.  All this helps to deliver smooth, direct power to ensure that the rider is always in complete control while experiencing a natural ride feel.

BATTERY INTEGRATION

Through the extensive use of hydroforming on the down tube and the precise laser cutting of the tube opening for the battery, as well as the perfectly matching two-component plastic cover, we were able to integrate the battery seamlessly into the lower part of the down tube. This is consistent throughout the various frame sizes. Charging is easily possible through the nicely integrated charging port at the motor bracket. Also, the battery is perfectly integrated into the down tube, yet it is possible to remove it for charging or when in transport. A further advantage of the battery being integrated into the down tube is the perfect protection from an impact which can occur when the bike falls over or is involved in a crash.

With the additional hole in the down tube, the battery can be turned on from deep sleep mode. That’s necessary when the bike is not used for longer than 6 months, or when the battery of the on/off switch is empty (this battery is normally charged by the main battery). To wake up the battery, just push a 4 mm Allen key (best to use the MERIDA EXPERT TR axle) through the hole, pressing the hidden button underneath.
