moteur yamaha pw-x

PW-X is an upgraded version of the latest generation of Yamaha engines with which the Japanese brand has successfully penetrated the European electric bicycle market. The PW series is a less nervous, more reliable engine for ebike with a good reactivity making it more manoeuvrable on European roads and circuits. PW-X is a more compact, lighter (3.1 kg), but also more efficient electric bicycle motor. Its main technical feature is its 5th Extra Power assistance mode, which allows you to gain power on uphills without losing control of the bike on downhills and straights. Excellent balance at the freewheel keeps the bike stable in all circumstances. In addition, the maximum level of assistance with this mode can reach 320% with a cut-off as soon as the speed reaches 25 km/h.

Yamaha is also making a good investment by improving the engine cooling system, which guarantees a long engine life even when the engine is subjected to high user loads over long distances. Moreover, it is associated with robust and powerful batteries with a capacity of 400 Wh or 500 Wh to be able to travel between 120 km and 150 km maximum. Due to its aggressive behaviour, PW-X is not suitable for non-sporting cyclists. It lacks comfort and quickly builds up speed with the first few strokes of the pedal. This engine equips the bikes of demanding sportsmen and thrill-seekers, as its level of assistance allows it to overcome all difficulties, from steep and steep slopes. It is preferable to associate the PW-X engine with its multifunction console with PW-X LCD screen. This optimizes engine performance and facilitates maintenance.

The console has a USB port for easy engine diagnostics and charging of a mobile device. It allows you to customize the displays of speed, distance traveled, riding modes, time or stopwatch, etc. With its reduced size and weight, the PW-X engine integrates perfectly with the frames of most standard electric bicycles. Its better weight distribution improves the centre of gravity. Very compact, it gives a more aesthetic final result. It is even possible to increase the life of the engine by placing it behind protective plates attached to the front of the frame to prevent the front wheel from being thrown out.

moteur yamaha pw-se


Between comfort and power

Yamaha is known for its powerful, rough-starting engines. But with the PW-SE, the brand is responding to an ever-increasing demand from cyclists looking for a combination of power, robustness and comfort. The electric assistance remains constant and fluid when starting and during pedalling, allowing a very natural piloting. And the engine provides enough thrust to allow ordinary e-bike users to go for long rides and overcome countless obstacles.

The PW-SE appeals to a wider audience because of its multiple qualities. It is powerful enough to satisfy the needs of the occasional sportsman. Because the bike is very responsive to the pace of riding, it offers unique comfort to please everyday users. You can swallow miles and climb steep hills without difficulty with this engine equipped with Yamaha’s latest technology.

This 3-sensor motorisation allows the pedalling power to be detected and the assistance to be adjusted automatically. The speed sensor displays actual data and the crank sensor measures the number of rotations related to pedaling. These 3 collected data are analysed several times a second and allow the rapid adaptation of the bike’s behaviour in record time. This processing speed makes for a very pleasant ride on electric bikes equipped with PW-SE.

The installation of the PW-SE engine is very simple. Its centre of gravity is positioned very low in the frame, as it is usually mounted near the pedals at the same time as its battery. It is slightly heavier than PW-X (3.5 kg). Given its heritage, the Yamaha PW-SE engine is far from being quiet, but it’s nonetheless more discreet than previous versions. Technically, like all Yamaha engines, it has a power of 250W. The power assist is switched off automatically from 25 km/h with a pedalling speed of 110 rpm. Given its versatility, 4 assistance modes are sufficient for this engine: ECO+, ECO, STD, HIGH at 50, 100, 190 and 280% respectively. Yamaha is known for the quality of its products and spare parts. The PW-SE engine components are of high quality and have a beautiful finish, which ensures a long engine life. The cyclist can therefore use his electric bicycle for long periods of time while keeping a powerful but controlled motor. Translated with www.DeepL.com/Translator (free version)


Intelligent assistance for the city

In the PW family, the TE model is the latest addition to the PW family. Its functionality and features are not really different from its predecessors. The motor has a rated power of 250W, weighs about 3.4 kg and has 4 modes of electric assistance. However, it only offers a maximum cadence of 100 revolutions per minute, making the engine more manageable and docile. This is the model that many urban e-bikers expect, as it focuses more on stability and comfort.

Yamaha has developed an intelligent technology that can adapt its race to its environment or user. It is the Quad Sensor System that equips the bike with 4 sensors in permanent interaction with the drive unit. The system detects and displays 4 data in real time: number of rotations, speed, torque and angle. It instantly analyzes the driving environment and operating conditions to quickly adapt the assistance mode. The automatic mode avoids manual settings on the console. The engine positions itself on ECO+, ECO, STD or HIGH according to the needs (from 50% to 280% assistance level). For example, it is no longer necessary to exert any effort to resume the race on an uphill climb. If the slope is steep, the engine switches to High mode and then in the descent, it automatically switches back to Eco mode for more moderate support.

Quiet and efficient, it is better suited for urban use. Its potential is best expressed over short distances and uneven terrain. It makes an excellent pair with the A-Console and Yamaha’s 1.7-inch LCD screen. This intuitive and accessible dashboard allows you to display and manually adjust all the engine’s navigation parameters such as instantaneous speed, daily odometer, range, total distance travelled, etc. But it can also be paired with the 2.8-inch C-connected dashboard, which has many functions that are truly indispensable in the city, such as GPS navigation. It is simply installed inside the frame behind the pedals with an Intube battery of 36V and a capacity of 600 Wh with a charging time of 5 hours to get good performance. This drive unit is installed very low on the frame of the bike in order to find the best balance between power and performance. This allows better control of the bike’s behaviour, especially when the unlocking kit is in use. Translated with www.DeepL.com/Translator (free version)
