1. About Yamaha Engines

The history of the well-known company Yamaha dates back to 1887, the year Yamaha was founded by Torakusu Yamaha in Japan. The product range includes articles from the areas of electronics, HIFI and musical instruments. The “Yamaha Motor Corporation” is a subsidiary company (founded in 1955). This corporation manufactures motorcycles, quads, engines etc. The new Yamaha mid-mounted electric bike engines became a real competition for the successful Bosch electric bike drive systems.

2. Yamaha Electric Bike Engines

The first Yamaha mid-mounted engine was already introduced onto the market in the year 1993 (!). Especially in Asia, Yamaha electric bike drive systems are very popular.
 
In 2014, Yamaha released a new mid-mounted engine drive system called “Next generation”. These drive systems are being used in, for example, GIANT E Bikes (Full-series, Prime & Explore series). The new Yamaha engines belong to the best electric bike drive systems on the market. They represent a genuine alternative to comparable Bosch engines.
 
The advantages of the Yamaha Powerdrive Next generation mid-mounted engines at a glance:
 
- Small and compact, but very powerful.
- Maximum torque: 60-80 Nm.
- Very lightweight (about 3,5 kg).
 
The Yamaha Next Generation E Bike engines are based on a 4 sensor technology (pedal frequency, power, engine speed, speed sensor). The associated battery (400 Wh) is much more powerful than its predecessor.

During the last years, there have been miscellaneous technological developments in the area of Yamaha drive systems. As a result, we nowadays have to distinguish between different Yamaha electric bike drive systems (current status 2017):
 
Yamaha PW (Powerdrive)
 
The Yamaha PW engine has been brought onto the market in 2014. Nowadays, it is being used in many electric bikes. This engine attracted considerable attention because it was relatively small and lightweight, but nevertheless very strong (70 Nm). Thanks to its three sensors the engine had very fine response behaviour. There were four support modes. Here we compiled the most important technical data of the Yamaha PW (Powerdrive) engine:
 
Power nominal: 250 W
Motor support: 25 km/h
Power maximal: 400 W
Torque: Peak torque 80 Nm (continuously) / max. torque 70 Nm
Gears: Hub gear / derailleur system
Weight: 3,5 kg
 
Yamaha PW-X
 
This powerful drive system has been brought onto the market in 2017. It was especially developed for the use in E-Mountain Bikes. Something very interesting about this drive system is a fifth support mode (“Extra Power Mode”), which is optimized for steep ascents. The reaction behaviour has been improved, too. The power has been raised to 80 Nm. In comparison to the Yamaha PW drive system, the engine support is much more subtle. The weight of the engine has been reduced from 3,5 to 3,1 kg. Another new feature is a powerful 500 Wh battery.
 
By the way: The electric bike manufacturer GIANT also uses the PW-X mid-mounted engines, but calls the system “SyncDrive Pro”, because it has been equipped with a special software developed by GIANT. The torque is 80 Nm, too. The performance has also been slightly increased – as a result, in the “Power” mode the support now reaches up to 360%. Even the weight and the measurements have been slightly reduced (in comparison to Yamaha PW-X). GIANT SyncDrive Pro comes with the powerful 500 Wh battery, too (however, older models can be upgraded with this battery, too).
 
Yamaha SyncDrive
 
The compact Yamaha SyncDrive mid-mounted engine has a capacity of 250 W and a powerful maximum torque of 70 Nm. What´s so special about this system is the so-called “Zero Cadence Support” – that means, the engine supports from the first crank turn, without any delay. Another advantage of this system is that the engine with crank set can be combined with a double chain ring, which enables you to ride with a higher pedal frequency on gradients. The system has got 4 support modes. In most cases, the Yamaha SyncDrive system is equipped with a 400 Wh battery.
 
By the way: The established SyncDrive drive system, which is being used in GIANT Full-E+ bikes, still exists – but now under the new designation “SyncDrive Sport”.

3. Is it possible to optimize / tune Yamaha engines?

Yes! In the meantime there are at least six recommendable tuning tools which you can use to tune Yamaha electric bike engines to make them much faster. There are tuning tools for all Yamaha drive systems available: Powerdrive / SyncDrive / PW-X.

4. Which Yamaha Tuning Tools do exist?

We want to present you some really good Yamaha electric bike tuning Products – for example, the new BluePed module, the Badassebikes Chiptuning Box and the Sx2 Dongle.

A) BluePed

BluePed

The BluePed module is one of the most elegant tuning solutions for electric bikes with Yamaha mid-mounted engines. This tuning tool can be conveniently controlled with a free Smartphone App. One of the big advantages of this device is that it offers an unusually large number of configuration options. The BluePed module does not only take away your electric bike engines 25 km/h speed restriction, it also enables you to set the level of the maximum engine support individually from 15 km/h up to 75 km/h (about 47 mph). Another advantage of this tuning tool is that your electric bike display will show all data correctly (current speed etc.). But if you use the BluePed App, your Smartphone display can even show you many more parameters! To make sure you always have a good view on your Smartphone display while you are riding, the BluePed tuning tool comes with a special Smartphone holder for your bicycle handlebar. Hint: In principle, the BluePed App is only needed to adjust the settings of the BluePed module (wirelessly via Bluetooth). All settings will be automatically saved. Due to the fact that the BluePed device can be switched on / off with your electric bikes light switch, you do not have to take your Smartphone with you every time you want to use your bike. Compatible with Yamaha Powerdrive. more

B) BlackPed Yamaha PW and PW-X / BlackPed+ Yamaha Syncdrive and PW-X

BlackPedThe new BlackPed enables electric bike tuning with a Smartphone App. After the BlackPed module has been installed into the engine compartment, you can use the (free) App to make various settings: You can adjust the maximum motor support (“PumaPed 1” until 100 km/h / “PumaPed 2” until 75 km/h), define the wheel size and much more. Of course, you can use the App to turn the BlackPed on or off, too. Because all settings you make will be automatically saved, the Smartphone does not have to be connected to the BlackPed module all the time – this means, you can use the BlackPed module without Smartphone, too. If you use the new BlackPed module, your Smartphone display will always show the correct speed, even if the tuning is activated – this is very comfortable if you fix your Smartphone to the handlebar with a special holder. BlackPed is compatible with Yamaha Powerdrive and PW-X, BlackPed+ is compatible with Yamaha Syncdrive and PW-X. more
