Why choose a Panasonic motor?

Before examining specific models, it is useful to understand why connoisseurs are so enthusiastic about this brand. It is not just about raw power (although they have plenty of that), but above all about the technology behind it.

1. Exceptional power (torque)

When we talk about power on an electric bike, we're talking about torque (expressed in Nm). The higher this number, the easier it is to start from a standstill or climb a hill.

Panasonic motors are renowned as being "the most powerful in their class." For example, the GX Ultimate delivers an impressive 95 Nm of torque, and the new GXM even reaches 100 Nm. By way of comparison, this is almost equivalent to the pulling power of a small gasoline-powered car.

Whether you weigh 240 pounds, are carrying groceries, or heading to the Alps, these motors will propel you to the top with ease.

2. "Auto" mode

One of Panasonic's major strengths is its AUTO mode. Many systems require you to manually switch between Eco, Tour, or Turbo modes. Panasonic does this work for you.

Sensors continuously measure the force you apply to the pedals. Are you pedaling harder into the wind or uphill? The motor immediately provides more assistance. Are you riding gently on flat ground? It automatically reduces support to save battery power.

The result: a very natural pedaling sensation. You don't focus on the on-board computer, but on your ride.

3. Japanese reliability

In discussions and forums, Panasonic motors are often praised for their longevity. Some users report that their Panasonic central motor is still working perfectly after 11 years of use, with documentation citing a maintenance-free lifespan of 10 to 20 years.

It's "set it and forget it," exactly what you want from a bike you use every day.

The engine range

Panasonic offers several motors, each with its own characteristics. Here are the main models found on modern electric bikes (2025/2026 models).

Panasonic GXM (2026)

The latest model. The GXM sets a new benchmark in performance.

Torque: 100 Nm, Weight: only 2.8 kg

Character: truly versatile. Thanks to intelligent software, the assistance adapts to your riding style. Robust enough for MTB, but smooth enough for commuting.

Extras: Compatible with a new generation of displays and apps (such as Komoot and Wahoo) for navigation and updates.

Panasonic GX Ultimate

Until recently the flagship model, and still one of the most powerful engines on the market. Its nickname is well deserved: "The Predator."

Torque: 95 Nm (sometimes indicated as 90 Nm in older documentation, but recent specifications state 95 Nm), Weight: 2.95 kg

Character: Pure power for the most demanding conditions. Very steep slopes or loaded cargo bikes? The GX Ultimate provides constant assistance, even at low cadences. It is the favorite for e-MTBs and trekking bikes.

Experience: Users describe the ride as "surprisingly smooth" despite the impressive power, as the engine always has a reserve of torque.

Panasonic GX Power Plus

Not everyone needs 100 Nm. For sports and trekking, there is the GX Power Plus.

Torque: 75 Nm, Weight: 3.2 kg

Character: Ideal for gravel roads, forest trails, and hilly terrain. Less extreme than the Ultimate, but still more powerful than many standard mid-drive motors from competitors.

Screens and batteries: the entire system

A good engine is nothing without a high-performance battery and efficient management.

Batteries

Panasonic is renowned for offering high-capacity batteries. While 500 Wh was long the standard, bikes equipped with Panasonic motors often have batteries rated at 720 Wh or even 900 Wh.

Advantage: fewer recharges and range anxiety (fear of running out of battery power) are a thing of the past.

Range: Although it depends on many factors (wind, tires pressure, weight, assistance mode), distances of up to 170 km, or even 200 km in Eco mode, are possible with these large batteries.

Screens

The Modern Panasonic LCD screens are often color and mounted to the left of the handlebars or in the center.

Functions: speed, distance, pedaling cadence, and remaining battery life. Connectivity: Bluetooth 5.0 on the latest models, compatible with apps such as Komoot and Strava. Navigation instructions can be displayed directly on the screen, allowing you to keep your phone safely in your pocket. USB port: convenient for charging your phone on the go via the built-in Micro-USB port.

On which bikes can these motors be found?

Panasonic does not supply its motors to just anyone. The brand often collaborates exclusively with manufacturers focused on quality and sportiness.

1. Crussis

Crussis is by far the largest user of Panasonic motors. The brand designs sporty electric bikes and e-MTBs developed entirely around Panasonic motors.

High-end models (GX Ultimate/GXM): e-Largo, e-Guera, e-Full, and e-Atland series. The "PRO" versions are often equipped with 95–100 Nm motors and larger batteries (up to 900 Wh). These are true off-road machines.

Entry/mid-range (GX Power Plus): e-Country and e-Cross series. Perfect for long rides and everyday use.

2. Flyer

The Swiss brand Flyer has historically been linked to Panasonic. A pioneer in electric bikes, it has been using Panasonic motors for its premium models for many years.

The combination of Swiss manufacturing quality and Japanese technology appeals to discerning cyclists.

3. Other brands

Panasonic motors are also found in bikes from manufacturers such as Kellys and Leader Fox (for example, the Orem model). These bikes often offer excellent value for money for a model equipped with a mid-drive motor of this caliber.

What do users say?

Beyond technical specifications, real-world experience is essential. On forums such as Reddit, many users, including heavier cyclists (110 kg and above), praise the climbing capabilities of these motors. Where other systems begin to struggle, the GX Ultimate continues without faltering.

Durability is also praised: these systems often operate for years without any significant problems, provided that standard wear parts (tires, chain) are properly maintained.

The only criticism sometimes concerns the total weight of the bike on models equipped with very large batteries. But that's the price you pay for a range of over 150 km.

Conclusion: Is Panasonic right for you?

Choose an electric bike equipped with a Panasonic motor if:

• Looking for power? With 95 to 100 Nm, no hill will be too steep for you, even when fully loaded.

• Want to travel long distances? Compatibility with batteries of 700 Wh and above is a game changer.

• You appreciate simplicity: Auto mode eliminates the need to constantly change assistance levels.

• You prioritize quality: proven and reliable Japanese technology.

Whether you choose a powerful Crussis e-MTB or a high-end Flyer for your daily commute, a Panasonic motor integrated into the frame offers you cutting-edge technology that you will enjoy for many years to come.
