In this video Justin shows two of the techniques to get regenerative braking from a geared hub that otherwise freewheels, unlocking the regen potential of these powerful little motors. In one case we're just swapping out the planet carrier for a fixed (nonfreewheeling) carrier, and in the other we're modifying the stock planet assembly and welding shut the freewheel clutch mechanism.

To understand and appreciate WHY we would do this, have a look at our live presentation on the benefits of regen from a couple years ago:
   • Regen Braking and Electric Bicycles, ...  

And also check out the GMAC motor which was at the start of this mission:

Special thanks to our friend Phil who's played a pivotal role in field testing and proving out regen with some of these smaller motors over the last year with his custom line of cargo ebikes:
