• removal of safety equipment (e.g. reflectors) or holders
• increasing the performance (tuning)

Your MERIDA eFLOAT CITY is approved for use with trailers for transporting loads and children weighing up to 27 kg.

Up to two children can be accommodated in special child trailers that are towed behind the bike.

Please note when using a trailer:

• The trailer is considered to be part of the total authorised weight with its actual weight, including the load.
• The trailer coupling may only be attached to the rear axle or on special mounts on the dropout.
• It is not permitted to attach the trailer coupling to frame tubes, rear stays or the seatpost.
• If it is necessary to replace the original thru axle in order to attach the trailer coupling or to clamp an adapter to the original thru axle, ensure that the axle thread and the thread of the axle nut completely overlap.
• Replacement axles must comply with the Technical Specifications of the original MERIDA axle (clamping width, thread pitch and thread length, material and diameter).
• If lighting equipment is concealed by the trailer, it must be visibly attached to the trailer. If riding at night, attach a battery/rechargeable battery light to the rear of the trailer.
• The maximum permissible speed specified by the trailer manufacturer must be observed. Follow the trailer manufacturer’s instructions.
• Only transport persons in authorised trailers.

Guide to component replacement with pedal assistance up to 25 km/h

* Note on category 3: The component manufacturer can only give approval if the component has been adequately tested in advance in accordance with its intended use and the relevant standards and a risk analysis has been carried out.

Your MERIDA eFLOAT CITY has been carefully manufactured and will normally be delivered to you fully assembled and ready to ride by your MERIDA dealer.

Short time

If you maintain your MERIDA eFLOAT CITY regularly during the season, you don’t need to take any special measures.

Store your eFLOAT CITY in a dry, well-ventilated place.

Longer time

The tubes gradually lose air during longer periods of inactivity. If the eFLOAT CITY is left on flat tyres for a longer period of time, its structure may be damaged. Therefore, hang up the wheels or the entire eFLOAT CITY or check the tyre pressure regularly.

Clean your eFLOAT CITY and protect it against corrosion. You can obtain special care products for this from your MERIDA dealer.

Remove the rechargeable battery from your eFLOAT CITY. Ideally, the rechargeable battery should be stored with a charge level of 30% and at temperatures between 0°C and 20°C in a dry environment. A well-ventilated room with a smoke detector, away from sources of heat or easily flammable materials, is best suited for storage.

To ensure the operational safety of your MERIDA eFLOAT CITY, the component bolts must be tightened carefully. This should be checked both before the first ride and at regular intervals.

Use a torque spanner with which the correct screw torque can be set. Approach the prescribed maximum screw torque from below in half Newton metres and check the tight fit of the component again and again in between. Do not exceed the maximum screw torque specified by the manufacturer.

For parts for which no information is available, start with 2 Nm.

On a bike with a standard straight top tube, there should be at least 25 mm between you and the top tube when you are standing over the bike.

The handlebar height relative to the saddle and the distance between the saddle and handlebars determine the inclination of the back. With low handlebars, you sit sportily and put a lot of weight on the front wheel.

The Ahead stem system is available, which can be used to vary the handlebar height

Stems for threadless Ahead® systems

On MERIDA bikes with Aheadset headsets, the stem is used to adjust the bearing preload. If the stem position is changed, the bearing play must be readjusted.

Figure 6. Stems for threadless Ahead systems

You can adjust the height to a limited extent by moving the spacers or flipping the stem on so-called flip-flop models.

The diameter and width of the original wheels and tyres were selected to ensure sufficient clearance between the rotating wheel and tyre and the frame, fork and other components. Any modification to the wheels or tyres can affect this tyre clearance. Tyres that are marked as the same size may have different widths when they are fitted, inflated and installed on the bike. Always check the tyre clearance with the tyres fitted and fully inflated, even if the spare tyres are the same size as the tyres to be replaced.

The distance between a properly inflated tyre and any part of the bike should generally be at least 6 mm. Always maintain sufficient distance between the rotating rim and tyre and the frame, fork and other components. Check the frame and fork regularly for damage and the area around the wheel for any foreign bodies or objects.

Figure 7. Tyre clearance on the front wheel

Figure 8. Tyre clearance on the rear wheel

When riding the bicycle, the tyres must not touch the fork, frame or other components if a suspension element is fully compressed or the wheels are deformed by lateral forces. With a suspension fork, for example, the tyre must have a minimum distance to the fork crown even when the fork is fully compressed.

New disc brakes must be braked in. Braking in helps to ensure constant and powerful braking performance as well as quiet braking under most riding conditions.

1. To do this, get on the saddle and accelerate the bike to a moderate speed on a flat stretch of road.
2. Then pull hard on the brake levers until walking speed is reached. Repeat this process twenty times.
3. Accelerate to a higher speed and brake the bike to walking speed. Repeat this process ten times.
4. Allow the brakes to cool down before continuing the ride.
5. Contact your MERIDA dealer if the braking effect of your brakes decreases or the pressure point becomes spongy.

In its final position, the quick release must be perpendicular to the quick release axle. It must not stick out at the side. The lever must be positioned against the frame or fork in such a way that it does not open unintentionally but can also be easily reached and operated quickly.

Figure 9. Quick release

1. Check that it is seated correctly by pressing on the end of the closed lever and trying to twist it.

   Result 1/2The lever cannot be twisted and is firmly seated.

   • No further steps required.

   Result 2/2

   • The lever can be twisted and moved.

   • Open the quick release and increase the pretension.

   • To do this, turn the clamping nut on the opposite side clockwise by half a turn.

   • Close the quick release and check again that it is seated correctly.

2. Then lift the wheel a few centimetres from the ground and tap the tyre from above.

   • A securely fitted wheel remains in the axle housing of the frame or fork and will not rattle.

3. To check the quick release on the saddle: Try twisting the saddle against the frame.

The pedals each have a right-hand or left-hand thread. The pedals are labelled with an “R” or “L” on the assembly side.

1. Place the two washers included in the delivery contents on both pedal axles.
   Figure 10. Pedal with washer
   
   
2. Turn the left pedal anti-clockwise into the thread in the left crank arm.
3. Tighten the pedal with a tightening torque of 35 Nm.
   Figure 11. Left pedal
   
   
4. Turn the right pedal clockwise into the thread in the right crank arm.
5. Tighten the pedal to 35 Nm.
   Figure 12. Right pedal
   
   

1. Check all screws for tightness, correct connection and correct fastening
2. Check quick release, thru axles, screw connections on the front and rear wheel and other components
3. Check the plug connections on the battery, control panel and display, as well as on the drive unit
4. Check the battery in its holder and the locking mechanism

Bounce your bike from a low height onto the ground. Investigate any rattling noises that may occur. If necessary, check the bearings, screw connections and the correct seating of the battery.

Carrying out a brake test:

1. Test the brakes while at a standstill by pulling the brake levers towards the handlebars and applying the full braking force.
2. Check that the front brake is working correctly. To do this, ride the bike at a slow speed and apply the front brake. The bike should stop immediately.
3. Repeat this procedure for the rear brake as well.

The pressure point must be stable immediately. If you can only feel a stable pressure point after actuating the brake lever several times, you should have your bike checked immediately by your MERIDA dealer.

Figure 13. Handlebar angle

1. Make sure that the handlebars are at a 90° angle to the front wheel.
2. Check that the handlebars are firmly seated so that they do not twist during the ride and cause you to fall.
3. Make sure that no cables are pulled or can get caught when you are steering.
4. Ensure that the handles are firmly seated and in good condition. If the grips are loose or have cuts, cracks or worn areas, replace the grips or have them replaced by your MERIDA dealer.
5. Make sure that the handlebar ends and any attachments are sealed with plugs. If the handlebar end plugs are damaged, replace them.
6. For handlebars with attachments at the end of the handlebars, make sure that they are clamped in accordance with the manufacturer’s specifications for handlebars and attachments.
7. Also make sure that handlebars, attachments, grips, brake levers and gear shifter are correctly attached and that safe handling of the bicycle, including unhindered steering, braking and gear shifting, is ensured.

1. Check that the saddle is correctly aligned and in line with the top tube.
2. Check that the saddle rails or clamp are firmly seated to prevent the saddle from twisting, tilting or shifting during the ride.

Note the error messages or codes shown on your display. Correct this before you set off Troubleshooting.

The integrated steering stop can twist in the event of a fall. Therefore, after a fall, it must be ensured that the steering stop is still centred by checking when stationary whether the handlebars can be turned to the left and right to the same extent.

Figure 14. Checking max. turning angle

1. Check whether the frame or suspension fork is broken or bent.
2. Check the carbon frame for cracks or soft spots in the carbon if your bike has a carbon frame.

1. Check the shifting system by shifting through all gears and making sure they run smoothly without any delays or noises.
2. Check the wheels by spinning them and looking for lateral runout, dragging brakes and loose spokes or axle play.

If you find any damage to these parts, do not continue your ride!

Even if no damage can be detected, pay very close attention to any unusual noises from your bike as you continue your ride. These could indicate damage or other problems. Do not ride any further if you notice any unusual noises.

If you have any doubts about the condition of the material after a fall or accident, please always contact your MERIDA dealer. Some consequences of a fall or accident can only be recognised if the bike is completely dismantled and examined for cracks or other signs of damage.

The following section explains how to fit the rear wheel.

1. Apply grease to the thread of the thru axle.
2. Insert the rear wheel so that the opening for the thru axle of the hub and dropout are aligned.
3. Push the thru axle from the non-drive side through the dropout and through the hub. The thru axle must touch the thread of the opposite dropout.
4. Tighten the thru axle hand-tight by turning the axle lever clockwise.
5. Remove the axle cover Removable axle lever
6. Tighten the thru axle to 9 - 13.5 Nm using a torque spanner and a 6 mm hex bit.

The following section explains how to remove the thru axle from the rear wheel.

1. Turn the axle lever anti-clockwise to release the thru axle.
   Figure 15. Turning the axle lever
2. Remove the thru axle in the direction of the non-drive side.

Proper lubrication ensures that the chain runs smoothly and quietly and extends its service life.

Depending on the degree of soiling, the chain must be cleaned at regular intervals to remove dirt and oil deposits. Special chain degreasers are not required.

Figure 18. Lubrication of the chain

Maintenance includes a complete check of all components.

The new bike should always be checked after the first ride.

After

• 100 km to 300 km of trips or
• 5 hours’ to 10 hours’ riding time or
• after four to six weeks, but
• after three months at the latest,

you should take your bike to your MERIDA dealer for an initial inspection.

The times given are intended as a guide, with an annual mileage of between 1,000 km and 2,000 km or between 50 hours and 100 hours of riding. The case that occurs first is decisive.

If you regularly ride on poor roads, the maintenance intervals will be shortened in line with the rougher use.

You can also carry out the maintenance work yourself if you have manual skills, some experience and suitable tools, e.g. a torque spanner. If defects are identified during the inspection, take action immediately.

Your MERIDA dealer will provide you with expert support on all maintenance issues.

Spare parts can be ordered from your MERIDA dealer. The required MERIDA part numbers can be found in the exploded views.

The luggage carrier of the eFLOAT CITY, eFLOAT TK, eFLOAT CC and eFLOAT HD have an MIK HD interface. A child seat which is intended for MIK HD interfaces can be fitted on this interface.
