Did they provide any images/diagrams/specs that you can share here? That would be very valuable info in this motor thread.
The pictures were not very useful, and I doubt I have the right to just post them online. The explanations from xiongda are quite clear though: they apparently use a one-direction bearing - so it cannot be reversed; ergo: no regen. As simple as that. You may ask user D8veh - he has a lot more experience with this tiny motor; maybe her has pictures of the gearing.
