It's totally unfair for me to see this video at 1:30AM when I can't shout with excitement! At risk of falling for a hype cycle, but this is a really fascinating development in electric assist bikes. I've always been told that regen braking isn't worth it for bikes, I can't wait to see if this changes that dynamic.
Don't mind me, I'm just daydreaming about a #Canada that invests in an ebike Manhattan Project powered by #GRINTechnologies, #Wike, and #EMMO. You know, instead of giving $29,000,000 to USA fossil fuel companies to lie to us about the feasibility of CCS (without a $200-$300 per-ton carbon tax).
"In this video Justin does a deep dive explaining the most exciting innovation to ebike hub motors in decades. Freegen is a novel modification to motor design that allows geared hub motors to both freewheel with no drag AND ALSO do regenerative braking. There is no longer a trade-off of one or the other. And it does this without any of the extra complexity of a traditional controlled clutch.
This new idea from the Israeli company Chargebike not only solves that problem, it also provides an a proportional regen based on how hard the lever is squeezed AND it can maintain that braking force even when the batteries are fully charged, something not possible with traditional controls."

#GRINTechnologies has a video about converting locking the clutch in off-the-shelf hub motors to enable #RegenerativeBraking
It seems like using a hub set up will add drag as well as extra vehicle mass, which is unfortunate if the brake isn't extending vehicle range.
I wonder if there's a way to mount the turbine shaft to a caliper that can engage against the wheel like a V-style rim brake, so the drag is only applied when a brake lever is engaged.
**Grin unveils groundbreaking geared hub motor with regen braking**
"…its braking benefit is often more important than its efficiency gains."
**"**Grin Technologies, a Vancouver-based electric bicycle parts manufacturer, teamed up with MAC to improve the motor. The result is the GMAC, which offers a new clutchless design and thus enables regen braking, even with a smaller, lightweight geared hub motor."
