1. The most common MTB wheel sizes : 27.5" and 29"

Let’s start with the basics : Wheel sizes are expressed in inches as a unit of measurement. Historically, ATVs were equipped with 26″ wheels.

There were not really any other sizes of wheels suitable for individual practices. It was cross country that brought the 29” wheels to the market to provide better grip on the ground.

The 27.5″ wheels then appeared to offer greater versatility and to offer a compromise between 26″ and 29″.

2. Advantages of 27.5'" and 29" wheels

27.5'' WHEELS

More manageable

As the 27.5’’ wheels are smaller, they provide more handling and agility, which makes the ride more straightforward and precise.

Smaller people are more comfortable with these kinds of wheels because they have less difficulty turning in narrow passages.


The 27.5″ wheels are logically lighter than larger wheels even though the weight difference decreases.

More acceleration

More versatile for less effort

If you practice on all terrains and are looking for versatility, prefer a 27.5″ wheel. Plus, it takes less effort to move forward than a 29″ wheel, especially on unobstructed terrain.


Fewer pedal turns

As seen with the 27.5” wheels, the smaller the wheels, the more pedal turns must be provided. Conversely, with a larger 29” wheel, you cover more distance with the same number of pedal revolutions. On the other hand, the acceleration is less important.

Optimized ground grip

Since the contact patch is higher on a larger wheel, it is best to go 29″ if you are riding on rough terrain. The angle of attack is different, it is weaker and lower, so it will allow you to overcome obstacles more easily.

More flexible and comfortable

As the wheel sizes are larger, the vehicle is smoother, more comfortable, but less responsive when cornering. Your two-wheeler is then more stable.

More yield

Riding with 29” wheels reduces friction on the ground, and therefore offers more performance. Driving performance is therefore optimized.

3. Which LMX configuration best suits my practice ?

The three existing LMX platforms each have their own specificities in terms of wheel mounting.

Let’s go back to their different equipment to determine which one is best suited to your practice.

LMX 161

Motocross-style equipment

The 26″ front and 19″ rear wheels are a cross-country setup for our ultralight electric motorcycle.

Indeed, having a larger wheel at the front makes it easier to overcome obstacles.

Front wheel

Rim 2.50 x 26''

LMX 56

Trial-type equipment

The 29″ front and 27.5″ rear wheels are a typical trial setup. Indeed, having a bigger wheel at the front will make it easier to pass obstacles and have better stability during technical passages.

If you hesitate between the LMX 64 and the LMX 56, it is at the level of your practice that you will have to turn to make your decision.
