Routine maintenance of your LMX: all you need to remember

Posted By: Zoé Lieux On:

Like any vehicle, our LMXs need regular maintenance in order to perform at their best.

Contrary to what you might think, maintaining your LMX is not a complex task, you just need to know a few guidelines for routine maintenance.

Our LMX 64s are made to be very reliable and maintain everyday life almost like a regular bike.

Here are the points to remember to enjoy the full power of your LMX for as long as possible.

For simplicity :

Maintenance mainly consists of cleaning and greasing your LMX after each ride and keeping the nuts tight as well as keeping the correct pressure in the tires.

Suspension components require regular maintenance according to the manufacturer's recommendations.

Transmission components, such as chain and sprockets, should be replaced every 2 years or 1500 km in off-road use, except in cases of abnormal wear.

Brake maintenance is also very important to keep the braking performance of your LMX at peak performance.

Before using the LMX, check the following points

- The battery should be charged and locked to the frame.
- All nuts and screws should be tight and locked. Use a medium thread locking resin if necessary.
- The wheels, suspension, handlebars and stem must be free from play and be tight.
- The saddle should be tight.
- Cables and electric wires must be fixed to the frame and must not move.
- The brakes should work properly. Storing or transporting your LMX in an abnormal position can cause the brakes to malfunction.
- The chain must have adequate tension.
- The wheels must be in good condition and the tires inflated with adequate pressure. Please consult the tire manufacturer or user manual for pressure ratings.
- The throttle lever must have a functioning return spring and not show any stiffness or slowdown in its travel.

When to replace the brake pads on your LMX?

To know if you need to replace your pads, you will have to measure their total thickness. These should be at least 2.5mm in total thickness with the backing.


To replace the pads of your LMX, please refer to the user manual supplied with the delivery.

Checking your brakes

If the operation of the brake levers does not provide satisfactory braking or if the lever play becomes insufficient, the free play adjustment at the levers should be checked. Using an Allen key, re-tighten the adjustment screw between the lever and the handlebars of your LMX until the desired clearance is obtained.

If this is not enough, it may be necessary to change the pads and bleed the brakes.

In general, it is recommended that you bleed your brakes every year to ensure optimal performance.

Washing and cleaning

It is recommended to remove the battery when washing the bike.

Extra care has been taken to seal the controller, located under the motor, but it is best to use as little water as possible on all electronics to reduce the risk of water entering the electronics. . Avoid spraying the screen, because even if it is waterproof, it may fog up between the outer shell and the inner part.

It is advisable not to use a pressure washer, as this technology can damage the stickers or internal components and affect the performance and durability of the bike. This can cause water to seep into the bearings and thus affect their proper functioning.

It is also imperative to keep the water jet at a minimum distance of 40 cm, avoiding delicate parts (controller, battery, bearings, axles, etc.).

Always grease the chain with a grease suitable for the conditions of use after cleaning with water to preserve its life.

A specific brush and a damp towel are the best tools to keep your LMX clean.


Lubricating your vehicle always comes after a good wash.

Regarding the type of fat to use, you should absolutely turn to specific greases for this use.

Indeed, using grease that is too thick and not dedicated can damage the equipment because residues will stick to the parts after lubrication.

Using a “dry” and non-sticky product is therefore the solution.

Here are some examples of suitable products:

- Muc-Off Nano Tech (Motorcycle Cleaner)

- Muc-Off Dry Chain Lube (Motorcycle)

A first cleaning phase can be carried out using a penetrating product type WD40. Care should be taken not to put it on the discs as there is a risk of contamination of the pads.

Once this is done, the chain should be wiped with a cloth.

The places to grease regularly on your vehicle are as follows:

- Chain tensioner
- Derailleur rollers
- The 2 chains

Warning: a belt transmission does not lubricate!

The frequency of lubrication therefore depends on the type of terrain on which you are riding and the conditions of use.

Additional maintenance

- Change the derailleur cable

- Change the seat post cable

- Cleaning and draining the fork

The recommended suspension cleaning and lubrication intervals are as follows:

After the first 50 hours

of use

Every year

Cleaning and lubricating the sleeves

Complete disassembly, cleaning, greasing, checking the seals and guides

It is important to clean and lubricate the inside of the fork to maintain peak performance.

Battery care and storage

We advise you to store the battery of your LMX in a dry and temperate place (between 10 and 30 ° C).

Below 10 ° C, the useful capacity of the battery can be reduced by 30%.

In the event of a long period without use, it is advisable to store it in a state of charge at 2/3 of its capacity. This corresponds to a no-load voltage of 52V.

It is recommended that you perform a 24 hour maintenance charge every 5 cycles to ensure cell balancing and optimal battery performance.

Note: The battery must not (or cannot) lose its charge level when not in use.

It is therefore a good indicator to recognize a potential malfunction of the battery of your LMX.

Fuse replacement

LMX vehicles are fitted with fuses:

LMX 64H (excluding LMX 64T)

1 fuse located under the battery: it protects and isolates the 12V circuit in the event of a problem or short circuit on it

Reference: 5x20 mm, type F, 400 mA

LMX 161H and LMX 161MX

1 round fuse located under the side fairing panel: it protects and isolates the DCDC input in the event of a problem or a short circuit on it

Reference: 6.3 x 30 mm, type F, 5 A

1 automotive fuse that protects the battery charging port in the event of reverse polarity on the charger

Reference: 20 A

And there you have it, you now have all the keys in hand to best maintain your LMX 64H or your LMX 161H!

Nothing very complex, the right strategy being to carry out regular checks to ensure the good health of your vehicle.

This avoids unpleasant surprises during an outing, but above all it allows you to have a two-wheeler in great shape that will hold up over time.

Now all you have to do is indulge yourself with your LMX!
