I recently installed my Magic Pie 2.0.

It has regenerative breaking on it. When I pull my brake handles, the motor charges my batteries in order to slow down my bike.

It takes the speed right off me.
--------------------------
Is regenerative breaking fairly standard on these electric hubs? Because if I DIDNT have it, this bike would be seriously scary to ride.

Grant it, I only have crappy old "V Brakes" on my MTB, but damn... I'm glad I have the regenerative brakes too.

I love regen since it helps lengthen the life on the brakes... Have a regen motor/controller combo on both wheels and I rarely have to use the regular brakes.
As a general rule, it only gives you about 5% back, but hey, it's better than zero.

Yeah... To me, the power you get back with regen brakes means nothing... The stopping power, means everything.

I'm very confident in my ability to stop that bike, in a hurry.

My BIONX kit does, and I smile everytime I get to a down hill steep and charge up a bit for free! No matter how much, it's the thought that counts!

I have heard MIT have made a single in-wheel hub that houses a battery and a motor and never needs plugging in because of the regen capabilities.....bring it!!

We need some new battery technology.

Some of the stimulus funds that were recently released are going to battery technology research for hybrid and plug in vehicles.

There is two brand new plug in car factories being built along with a commercial truck factory... These are plug ins, not hybrids!

The guy that is building these factories says he has a plug in car battery the size of a shot glass, and a commercial truck battery the size of a pizza box. He says his ultimate goal is to create a battery capable of powering an entire neighborhood; a battery the size of a dumpster.

Good stuff! If China doesn't decide to turn out our economy like a light switch...

There must be some real wizards at MIT if they are able to violate the laws of thermodynamics to build a battery/wheel that doesn't need plugging in...OVERUNITY baby...sweet...NOT

The guys at MIT will just pull the extra energy that's going into that wheel outta hyperspace, yeah, that's it!

Nanowire battery promises to hold 10x the capacity of today's lithium batteries. I'd love to see those things on e-bikes! Imagine an under the saddle battery pack that can take you 100 miles!

Power is power...
Nanowire is just that... Small...
The second you add enough for the power requirements of an LEV you start running into regulation issues and that equipment is going to be the same size as the newest lipos. (I've obviously simplified it {I've got a degree in physics**.

You need to pull the energy that's available from the earth's momentum (gravity well)through the solar system.

.......google can be employed to verify facts...gravity and human effort doth not make a perpetual motion machine......and therefore MIT have not violated any physical laws!!

It's a123 system battery, nothing special, and the power is basically nothing, pancake motors have been around for generations and are for low speed.. It probably does max 10mph for 25miles..
I can do that with $40 worth is HEAVY SLA batteries

I have regen on my TForce and I like it a lot, I simply cannot imagine my bicycle without it.
Rain the same stopping power, wheels never blocked.
My battery is well protected by electronics to allow for overcharging.
