Progress in Lithium Battery Technology As the electric vehicle (EV) and ebike market continues its rapid growth in both the US and the UK, some exciting news has recently been announced which will have a major effect on the industry. Researchers have developed a new battery system which will allow EVs to be recharged almost instantaneously.  This technology, dubbed the ‘Ifbattery’ by its creators, can be produced cheaply and is environmentally friendly. It uses a system known as a flow battery, but has been adapted to work without the membranes usually used in such units. T..

Display comparison

While both bikes offer powerful mid-drive systems and sporty styling The Yamaha PW-X has the edge in terms of MTB use thanks to . However Bosch are working

Yamaha have made their mid-drive motor lightweight and compact by reducing the drive unit’s size in the PW-X model by almost 13% compared to previous models. That has resulted in making it a lighter component and it now weighs in at 3.1kg.

This compares to the heavier 4.0kg of the Bosch Performance Line CX drive unit. While Bosch’s system is heavier, it has been designed to create a 28% smaller overall surface area than the Bosch gen2 performance motor – giving more streamlined aesthetics and performance.

When it comes to the motors performance there is not much to choose between the two. The Yamaha PW-X can offer slightly more torque at 80 Nm when in EXPW mode while the Bosch Performance Line CX offers a max torque of 75 Nm in its Turbo mode.

The max support speed for both bikes is cut off at 25km/h as in line with e-bike regulations. Both bikes offer good support mode options with the Yamaha offering 5 options compared to 4 from the Performance Line CX. The max support percentage is also slightly higher from the Yamaha model at 320% compared to the max support of 300% from the Bosch model.




The PW-X comes with an updated interface built to withstand tough rides and help the user focus on the ride. It has an ergonomic switch and LED Assist Mode Indicator to improve the experience while you ride. You can keep track of several statistics on this dot matrix LCD, such as the bicycle speed, cadence, clock, trip distance and battery capacity.

The Performance Line, on the other hand, offers a choice of three different on-board computer systems namely the Intuvia, Nyon and Purion. The Nyon display is comparatively more advanced than the Yamaha interface and provides a host of functionalities including GPS, personal training modes, data storage, riding modes, distance and cadence tracking and more. Additionally it recommends when to shift gears and can inform you when your e-bike needs servicing. The Nyon is the most advanced e-bike display with GPS and can be linked to a smartphone app.

Battery Comparison

The Yamaha lets you choose between 400wh and 500wh batteries which can be attached either to the rear carrier or the down tube. Bosch pulls ahead when it comes to e-bike batteries with its PowerPack series that comes in 300, 400 and 500wh and you can get either a frame or rack battery. What’s special about the PowerPack is the option to pair two batteries and enjoy double the normal range with the DualBattery system.

The distance that can be covered in one full charge can vary due to a number of factors such as flat/hilly terrain, riding mode, rider weight and input, tyre choice and average speed. However, the approximate range for the Bosch Performance Line is an average of 80km to 120km depending on battery power, and up to 270km with the DualBattery. The Yamaha PW-X can also vary in range depending on which of its 5 modes

you choose. (
