I somehow missed this. Was it mentioned on the forum before. It's a clever idea, but would be expensive to have it on your own bike. Is the benefit worth the expense. Is it better to keep things simple? Freegen Explained
4mins in and im struck by the point of them basically applying the brake, but it is in a stopped fixed position, when the reality is you only have the disc stopped when you are stationary.
Otherwise the rotor is still in motion as the brake is applying pressure and slowing the wheel, not stopping it the second the lever is applied.
Interesting all the same and i like that engineering is looking at ways of using momentum to produce electricity

To me it seems like a lot of effort to achieve very little. Price difference between 15Ah and 17.5Ah batteries is less than £20, so to me it makes more sense to just buy a bigger battery.
By regenerative braking you will add what? 10% extra range maybe? At cost of extra complexity, weight and extra £ of course.

Another point is that it's only on one wheel. Most of the braking on a bike is done by the front, so you could only reclaim about half the energy at most.
There may be a flaw with the plan, but I am not sure:
Effectively this system places the torque generated between the disc pads and disc in series with the torque generated by regen in the motor, I think.
Therefore surely a broken wire can potentially remove the regen, leaving no rear brake? Which would contravene the two independent braking systems requirement.
