DJI Avinox vs Bafang Ultra: The New Mid-Drive Compared

DJI's entry into e-bike motors with the Avinox drive system has generated a lot of buzz — and for good reason. But how does this newcomer actually stack up against the motor that's powered serious high-performance builds for years: the Bafang Ultra (M620/G510)? Here's an honest look at how the two compare on the things that matter.

The contenders

The DJI Avinox is a compact, lightweight mid-drive with slick app integration, strong nominal torque, and a polished, quiet feel aimed squarely at the premium lightweight eMTB market. The Bafang Ultra (M620/G510) is a heavier, brawnier mid-drive that has become the backbone of the high-power custom scene thanks to its torque, robustness, and — crucially — its tunability.

Power and torque

On paper, both motors put out roughly 1,000W nominal and triple-digit torque figures. The Avinox impresses with strong torque in a very light package and refined, natural-feeling assist. The Bafang Ultra's advantage is headroom: with the right aftermarket controller, an Ultra build can be pushed well beyond its stock output, which is exactly why it's the darling of the high-power community. If your ceiling is refined trail assist, the Avinox is compelling; if your ceiling is “as much as the drivetrain can take,” the Ultra platform opens doors the Avinox keeps closed.

Weight and integration

This is where the Avinox shines. It's noticeably lighter and more compact, enabling clean, integrated frame designs and a nimble ride. The Bafang Ultra is heavier and bulkier, but that mass comes with mechanical robustness that stands up to serious abuse and big power. It's the classic trade-off: lightweight refinement versus rugged, high-ceiling capability.

Tunability and the aftermarket

For builders, this is the decisive category. The Bafang Ultra sits inside a massive, mature ecosystem of controllers, displays, and parts. Pair one with a high-current controller from our Bafang Ultra M620 / G510 controller collection and you can unlock power and tuning flexibility the closed, app-locked Avinox simply isn't designed to offer. If you value a plug-and-play, sealed experience, the Avinox delivers; if you value control and upgrade paths, the Ultra wins.

Which should you choose?

• Choose the DJI Avinox if you want the lightest, most refined and integrated turn-key trail experience and you're happy inside a closed ecosystem.
• Choose the Bafang Ultra if you want maximum power potential, proven durability, and a deep aftermarket you can tune and upgrade for years.
