Bosch should be worried after several bicycle brands just announced their first e-bikes built on top of DJI’s compact and lightweight Avinox drive system, which is surprisingly powerful and torquey. These international brands include Forbidden, Unno, Smartmotion, Megamo, Paprika 53, and Teewing, all of which have new e-bikes built around the 1000W Avinox motor that’s capable of producing a very responsive 120Nm of max torque.

I haven’t tested the Avinox drive system myself, but a number of reputable reviewers are impressed — and it’s only DJI’s first salvo into the market. The Avinox system was first launched inside a mid-drive electric mountain bike — a segment dominated in sales by Bosch — from the DJI-offshoot brand Amflow. Most of the new bikes announced today are also electric mountain bikes, although newcomer Paprika 53 is positioning its Model 25 GT as an electric gravel bike.

It’s a very promising start for a very promising drive system from the world’s leading maker of consumer drones.
