If you’re looking for the best electric bike motor, there are many options available. We’ll look at the M615 motor, Brose Drive S Mag, Shimano EP8, Yamaha PW-X3, and more. If you’re still not sure, check out our reviews of each motor so you can decide for yourself which one is right for you. We’ve included links to purchase each of these motors, so you can compare and contrast them.


The Bafang M615 ebike motor is a mature system used by millions of people around the world. This motor transforms your bike into a powerful machine, flattening any hill. Unlike other motors, this one isn’t suitable for super-old bikes. Alternatively, you can buy one from VOLITION, Australia’s largest and most experienced mid-drive motor reseller. The motor will fit into most bikes with a bottom bracket width of 68-120mm.

The Bafang Ultra electric bicycle motor offers 160 Nm of torque, far more than the best mid-drive motors. This bike motor provides a true seat-of-the-pants thrill ride. The M615 ebike motor also features a torque-sensing bottom bracket, so you don’t feel the motor pulling hard on your legs. It is available for $2,999, and offers more power than many light electric motorcycles and scooters.

Brose Drive S Mag

The Brose Drive S Mag ebike electric motor is an improved version of the company’s previous 2.1 mid-drive motor. It now uses magnesium instead of aluminum, and takes up 15% less space, while still offering plenty of assistance. It was the second most powerful motor tested, but its most significant difference is that it’s smaller, lighter, and offers walk assistance functionality. Compared to other ebike motors, it offers a natural ride-feel and remarkably low pedal resistance outside of its power envelope.

The Drive S Mag ebike motor is vertically mounted and produces 36Volts of full power. The slackness of this motor helps you enjoy the ride without feeling tense, even at high cadences. It also offers a smooth and comfortable ride, while its 90 Newton-meters of torque are optimized for city usage. This makes it a great choice for a variety of riders and environments.

The Drive S Mag produces 90Nm of torque, doubling its predecessor’s torque. It also supports your effort up to 410%. While the Bosch Performance Line CX is a close second, it can’t match the Brose Drive S Mag’s torque, power, and support. It also produces a powerful hum. However, this motor is not for everyone. If you’re not sure if it’s for you, consider Brose’s Kenevo review and get your own ebike.

This motor is compatible with both two and three-wire speed sensors. Brose has a 630Wh battery, speed sensor, and Drive S Mag electric bike motor. The Drive S Mag is also compatible with Brose’s BLOKS 14d remote and display, allowing you to customise the motor and make it fit your needs. The Brose Drive S Mag ebike motor is the most powerful electric bike motor available in the market.

Shimano EP8

While the EP7 motor is considered the quietest electric bike motor on the market, the EP8 delivers significant improvements in performance. The motor is quieter while pedaling, but it becomes audible on steep terrain. This is because the EP8 motor uses an internal clutch mechanism that prevents the motor from slipping off the cranks when the bike is not in use. This helps reduce drag and resistance, and the motor produces a metallic ‘clack’ when it rotates.

The EP8 is designed for city riding and trekking. It has an internal geared hub that maximizes torque output for smoother shifting. It is also quieter and less noisy than competitors. The EP8’s display also provides battery level information, with five bars to indicate battery level. While the EP8 doesn’t have as many user-friendly features as Bosch and Brose, it does have the best display integration in the market.

The motor’s assist characteristic at start affects the level of motor sensitivity. On the fast setting, the motor responds to pedal pressure without dropping off, while low setting requires more effort. The lower setting responds to pedal input and crank rotation at a much slower pace. Neither setting has a great effect on battery consumption. However, it affects power output for less than a full crank revolution.

The EP8 motor is lightweight. The motor weighs just over a pound and is designed for lightweight bikes. The weight reduction enables a super light bike to use the motor, without sacrificing power. Shimano’s E-Tube Project app allows riders to change the maximum torque. Hence, the EP8 is the best ebike motor for light weight cyclists.

Yamaha PW-X3

The PW-X3 ebike motor is one of the premium ebike motors on the market today. Its improved torque and weight are key advantages. This motor allows for rapid acceleration and excellent arguments even on steep terrain. This motor also has the best power-to-weight ratio of any ebike motor available today. This is an impressive package for those looking for an ebike motor that will last them for many years to come.

The motor comes with eight battery options, including the “Multi Location 600 Wh” battery that’s integrated into the frame. At 3.8 kg, it’s a good balance of weight and range. If you’re looking for a sporty e-mountain bike, the “Interface X” battery can be mounted above or below the stem. Its battery monitors the amount of charge left in the battery, which is very useful for tracking your mileage.

The Yamaha PW-X3 ebike has a comprehensible interface. It comes with a sleek display that can be mounted on the stem below the Ahead cap. Its LCD display provides important information like speed, battery charge, and other metrics. However, the PW-X3 can’t be used with external devices such as Garmin, Echowell, or SIGMA.

The PW-X3 has a relatively smooth power curve. It has a high torque to weight ratio and is comparable to Shimano and Bosch bikes. Its battery is nearly identical to their rivals’ batteries. As far as noise is concerned, the Yamaha PW-X3 motor has no rivals. Its noise levels depend on the frame material and location. In addition to bumps, the motor also generates noise from coasting and bumps.

Giant SyncDrive Pro

The SyncDrive Pro ebike motor delivers a powerful 80 Nm of torque. Its narrow clutch spacing helps the motor kick in instantly and maintains power support. This is especially useful when climbing steep hills. The motor also provides a smooth ride, with tunable assistance ratios that give you more control. The motor is also quiet and silent. It is a great option for riders looking for the best balance between power, performance, and battery efficiency.

The SyncDrive Pro ebike motor has a 250-watt power output. Giant collaborated with Yamaha, a world leader in quality, to produce this high-performance electric motor. It provides instant torque up to 80 Nm, a useful feature for acceleration and hill climbing. In addition, the motor is lightweight and can be serviced at home if necessary. The SyncDrive Pro is compatible with all major brands of ebikes.

The Giant SyncDrive Pro is an electric bike motor that produces 80 Nm of torque. It is more powerful than its predecessor and is comparable to motors from Bosch Performance Line CX Gen 4. The motor weighs 2.7kg, which is a substantial improvement over the previous model. The extra ground clearance is a benefit, and the motor’s structure has been optimized to work with the Maestro suspension linkage.

The Giant SyncDrive Pro ebike has a PedalPlus 6-sensor system that detects your pedalling effort to deliver the best amount of electric assist. The battery-free motor is quiet and works seamlessly with your pedaling style, so you don’t feel like you’re riding without a motor at all. It’s like a natural boost to your energy. There’s a lot to be said for quiet and smooth ebikes.
