"Level 4 ADV: This model features the Aventon Ultro S mid-drive motor, which is Aventon's first in-house mid-drive motor. It delivers 750W of peak power and 100Nm of torque."
"The Aventon Ultro S mid-drive motor is not a simple "rebadged" generic third-party motor. Rather, it is part of Aventon’s proprietary drive system family, which they have been developing since 2019 to differentiate their products from generic e-bike brands.
While Aventon owns its manufacturing facilities in China, their approach to mid-drive development typically involves a collaborative model similar to how major brands like Specialized or Giant work. Aventon provides the core software, firmware, and motor mapping—which define the bike's "feel"—while partnering with specialized hardware manufacturers (such as Gobao in some instances) to produce the physical motor components. This allows them to maintain proprietary control over the ride characteristics and integration, distinguishing them from brands that merely "white label" off-the-shelf motors."
"Gobao (officially Guangdong Gobao Intelligent Technology) is a major Chinese electronics company that has recently emerged as a significant supplier in the e-bike drive system market. Founded in 2002 and headquartered in the Songshan Lake high-tech zone in Dongguan, China, the company built its reputation as a global leader in e-bike controllers, reportedly shipping over 30 million units annually.
Following its success in electronics, Gobao expanded into complete e-bike drive systems in 2019. Their "P" series motors, such as the P100 and P100 Pro, are designed to compete directly with established mid-drive manufacturers like Bosch and Shimano by offering high-torque, thermally efficient solutions with custom software integration for OEMs. Rather than acting as a simple off-the-shelf supplier, Gobao provides comprehensive, customizable "ecosystems" that include motors, batteries, displays, and mobile applications, allowing brands to tailor the ride feel to their specific product lines."
