Bafang M510: Overview & Specifications

The Bafang M510 motor, launched in June 2021, represents a significant improvement over its predecessor, the M500. Designed specifically for electric mountain bikes (e-MTBs), the M510 focuses on delivering a powerful yet lightweight solution for challenging terrains. It boasts a maximum torque of 95Nm and a peak power output of 600W, making it one of the most powerful motors on the market. Despite this power, the motor weighs only 2.9 kg, thanks to a magnesium alloy housing, which is 500 grams lighter than the M500.

Bafang motors are well-regarded for their reliability and affordability, offering strong performance at a lower cost compared to premium brands like Shimano and Bosch. The M510 supports a high cadence of up to 120 rpm and features enhanced waterproofing to withstand various weather conditions.

The Bafang M510 in Action: Power & Performance

The Bafang M510 is praised for its stable power tuning and smooth output, making it a top choice for mountain bike assembly. The motor’s high-precision torque sensor accurately adjusts power based on real-time cadence and pedaling force, ensuring a seamless riding experience even on rocky or uneven paths. The gradual power delivery at start-up eliminates the sudden surges common with other motors, enhancing rider control and stability, especially crucial when navigating tight curves or steep climbs.

The M510 features prominent cooling fins on its housing, visible behind the chainring, which help dissipate heat efficiently and ensure the motor performs well under high load conditions.

In terms of sound profile, the Bafang M510 is not the quietest motor available. Testers have noted that while its noise level is slightly higher than competitors like the Bosch Performance CX and Shimano EP8, it remains manageable and not overly disruptive. Interestingly, the M510 performs better in terms of noise reduction during downhill rides compared to Bosch and Shimano motors.

Despite its many strengths, one significant issue identified is the motor’s momentary shutoff during gear shifts, which can cause a loss of momentum and hinder performance on technical uphill climbs. However, the motor compensates for this with its fast speed, low noise, and good range.

The M510 delivers robust power even at low pedaling input and cadence, which can sometimes make its power delivery feel less dynamic. However, the motor’s extended power in the Boost and Race modes provides continuous assistance even when pedaling stops, making it easier to navigate technical sections and obstacles. This characteristic, while occasionally feeling less harmonious, is beneficial in certain scenarios.

The motor’s power engagement is more gradual, with a slight delay when resuming pedaling after a stop. This delayed response can be challenging in tight turns or technical terrains but helps prevent wheel spin during steep or slippery starts.

Key Features & Innovations

Torque Sensor & Power Management

The M510’s torque sensor finely tunes the motor’s power output according to the rider’s pedaling force, resulting in a natural and intuitive riding experience. This is particularly advantageous in mountain biking, where smooth and controlled power delivery is essential for handling complex terrains.

The Bafang M510’s Battery & Range

The M510 is compatible with high-capacity batteries like the 14Ah 672Wh, offering a range of 80-100 km on medium to long-distance rides. Paired with an 840Wh battery, it can achieve over 34km and 1462m of vertical climbing in high assistance mode. Even under continuous high-power demands, such as during steep climbs, the motor maintains consistent output, ensuring reliable performance throughout the ride.

Next-Level Connectivity

The Bafang GO+ App provides extensive functionality, enabling riders to monitor their e-bike’s condition, adjust motor settings, and track performance metrics via Bluetooth. This app supports firmware updates and diagnostic checks, offering a personalized and easy-to-maintain riding experience. Through the app, users can access various data generated by the bike’s sensors, including real-time power output, cadence, and battery status. The user-friendly interface offers clear and concise data displays, helping riders make informed decisions during their rides. Additionally, the app allows for customization of power settings and sensitivity adjustments, catering to individual riding preferences.

The app also enhances the riding experience by providing features such as route recording, detailed performance analytics, and easy sharing of ride data on social media platforms. This digital connectivity improves the overall functionality of the motor and fosters a more engaging and interactive biking community.

The Bafang M510’s Compatibility

The Bafang M510 isn’t the only player in the mid-drive e-MTB motor game. Top contenders like Bosch’s Performance Line CX and Performance Line Speed, Shimano’s EP8 and STEPS E8000, Yamaha’s PW-X3 and PW-ST, and Brose’s Drive S Mag and Drive S Alu are all vying for riders’ attention with their own strengths.

Compared to its predecessor, the Bafang M500, the M510 brings significant upgrades to the table. By utilizing magnesium alloy, it shaves off 500 grams, resulting in a more agile and playful e-MTB experience. The refined torque curve delivers smoother, more consistent power across varying pedaling cadences while maintaining a peak torque of 95 Nm. Additionally, enhanced software algorithms ensure a seamless ramp-up of power, making starts and stops feel natural and controlled.

When pitted against these industry giants, the M510 holds its own, often matching or even exceeding their power and torque output. While it might be slightly noisier, particularly on descents, the M510 compensates with a wider power and cadence range, adapting effortlessly to diverse riding conditions. One minor drawback is that its connectors could be more secure, as they may occasionally loosen during transport.

Bafang M510: Minor Issues & Potential Solutions

Despite the many ways the M510 has impressed, there are a few areas where it could be further refined. The remote control, another integral part of the system, could also benefit from some improvements. Its current build feels somewhat plasticky and delicate, which might not stand up well to the rigors of regular use, especially in outdoor conditions. A more robust material or design could enhance its durability and user experience.

The display’s plugs could be improved. They are prone to accidental disconnection during transportation, which can be frustrating for riders. Implementing proper clips or a more secure connection system would help ensure a stable, uninterrupted connection, enhancing the overall reliability of the system.

While these improvements are minor, addressing them could significantly enhance the user experience and the overall performance of the M510, making an already impressive e-bike motor even better.
