Whether you ride it or not, the worldwide electric-assist bicycle boom is unstoppable. And when it comes to electric-assisted bicycles, the motor is a topic that cannot be avoided. Focus on this area, it can be said that the eight immortals to show their talents, there is a whole vehicle brand to take the plunge into the electric power, there are accessories factory full bloom, organic industrial enterprises traffic leader down the field, and "born" to engage in electric power bicycle motor ...... Today, we summarized some of the main motor brands for your reference as below.

Brand：Bosch

Country: Germany

Founded: 1886

Bosch was founded by Robert Bosch in Stuttgart, Germany, and is today a large multinational supplier of engineering technology equipment.

Bosch has a wide range of electric-assisted vehicles, which can be mainly divided into Active Line, Performance Line, and Cargo Line.

The Active Line series is mainly used for commuting, with a 40Nm torque output providing mild acceleration performance, while publicity-wise the company positions it as a good helper for users' city road cruising, with a design speed of 20mph (about 32km/h). It is worth mentioning that this motor won the 2017 Red Dot Award for product design in Germany for its elegant exterior design.

Red Dot Award-winning Active Line series motors

The Performance Line series is designed to provide comprehensive sports performance support and is divided into Cruise, Sport and Speed products, with Cruise outputting 65Nm of torque and Speed providing 85Nm of torque output, and Sport and Speed reaching a maximum speed of 28mph. Line is equipped with a new generation of drive units, which can provide riders with a more natural riding experience and less resistance at high pedaling frequencies; users can also choose from the PowerTube series of batteries to provide higher power or longer endurance.

The Cargo Line series of mid-drive motors are designed for freight transport and are powerful in handling heavy loads. The motor corresponds to Bosch's new software to be released in 2021. The Cargo Line's predecessor has improved pedal matching at lower speeds for easy starting and slow riding when carrying heavy loads. The 2.9kg motor has a peak power of 1250w and provides 85Nm of torque, making it useful for carrying cargo even on steep slopes, and is available in 25mph and 45mph speed limit versions, with a maximum load of 250kg. Bosch engineers have optimized the cooling function with special designs in terms of surface area and shape. This series is designed to provide a sustainable, low-noise alternative to fuel-fired motor vehicles used for inner-city freight transport, and has a positive impact on the issue of carbon peaking and carbon neutrality.

The innovative point of Yamaha PW CE motor is its silent feature. At the same time, this motor weighs 2.9kg, has a maximum power of 250w and provides an output torque of 50Nm, which is basically sufficient for inner-city slopes.

The design that fits the frame is a major selling point of PW CE

This product offers a more comfortable riding experience, and other features include Walk Assist, a feature designed for off-road pushing scenarios, and Automatic Support Mode, which responds to changing conditions and automatically selects the most appropriate mode; this mode is an important feature of Yamaha's different ranges.

In addition to commuter products, PW-X3 is also a new product recently launched by Yamaha, which is mainly designed for mountain bikes. Compared to its predecessor, the PW-X2, the X3 offers a higher output torque of 85Nm, in addition to a smaller and lighter profile than the X2. This product is also equipped with automatic support mode.

Use Yamaha motor eBike Brand - Giant

The predecessor of ZF Sachs AG, "Fichtel & Sachs", was founded in Schweinfurt as a family business. The company entered the field of electric-assisted bicycles in 2018, when ZF, Magura, BMZ and BFO established the joint venture SACHS Micro Mobility, and the Sachs RS electric-assisted bicycle engine was born in the same year.

Sachs' RS motor has an amazing 110Nm of torque, this motor weighs 3.6kg and is slightly heavier than Brose's Drive S Mag motor, but the power performance is theoretically better on steep hill rides. The main problem with this motor, however, is that the mode of power support is largely dependent on pedaling frequency, which can lead to acceleration during sharp turns and braking on steep hills. It also provides less power support when pedaling frequency fluctuates widely, much less than the maximum power that can be provided; and it is noisy on downhill slopes. In terms of developing and integrating the RS system, Sachs offers greater scope for modification and also offers a complete system containing battery, display and software; the future trend for this motor is a modular EOX system equipped with Sigma, with the help of which the user can customize the riding mode, thus improving an otherwise uncomfortable riding experience. Sachs also offers the Sachs GT 525 motor for hardtail or city riding and the Sachs CT 725 motor for load carrying, also with a wide range of application scenarios.

Brand: Brose

Drive S Mag performs well in testing

The motor is made of magnesium housing, weighs 2.98kg and has a built-in transmission consisting of a belt and two sprag clutches to transmit power. The clutch is completely silent and there is no added resistance to pedaling when there is no power, which is an important advantage of the Drive S Mag motor. Meanwhile, in a review organized by E-Mountainbike magazine, the motor received high scores in power support, design/weight, internal gear ratio, volume and riding experience, the motor received high scores in items such as power support, design/weight, internal gear ratio and riding experience. The motor has a maximum torque of up to 90Nm, which can peak in Flex Power mode, providing up to 410% support and thus providing good performance in mountain riding, but the high noise level in this mode is one of the main drawbacks of this motor.

DU-EP800

The EP8 system is now widely used among mountain bikes, and Shimano says its compact size, linear power output and calibrated smooth running characteristics at high pedaling frequencies can also be applied to commuter and touring bikes. There are some reviews that suggest it's too aggressive in some road and gravel scenarios, but the specs and shape are trending towards becoming the new standard - thanks to Shimano's dominant position in the accessories space.

Drive unit weighing 1.92kg

In general, motor performance can be evaluated mainly from the perspective of output parameters, light weight, integrated frame, supporting software, etc. Before placing an order, users need to understand how much power they really need, and then choose the right motor according to their riding scenario.
