Hi, I was wondering what people thought about this project. how much it might cost ? performance guestimates etc. ?

Tried this quoting for the first time .lets see if it works Iwonder if the Panasonic vivi rx-10s has proven to be a success in its chosen markets the bike features regenerative braking and ups the range well in excess of 60 miles weight seems about 3kg. more than the conventional type AlThere have been many energy capture and regeneration attempts with bikes in the past, but they never last and often don't work well. A bike and rider simply doesn't have the mass and speed to make the added complexity worthwhile. Energy conversion always entails losses, so any kinetic energy is best used at the time whenever possible when it's present, rather than attempting to store it for later use.
Those of you who follow formula 1 racing will know of the KERS energy recovery system tried this last season and will know how that has failed to live up to expectations. That's with half ton cars repeatedly forcefully stopping from 200 mph, this containing energy that dwarfs what we could produce, but it's only after much effort that it's beginning to show some possibility of usefulness.

I know about this but have my doubts. Panasonic are just trying out a batch of 3000 in Japan only, not like their usual confidence. The hub motor version of it already sent out to other markets in very small quamtities had the regenerative braking left off. I take all e-bike range claims with a pinch of salt until properly tested, they often do miraculous things according to their makers.Tried this quoting for the first time .lets see if it works Iwonder if the Panasonic vivi rx-10s has proven to be a success in its chosen markets the bike features regenerative braking and ups the range well in excess of 60 miles weight seems about 3kg. more than the conventional type Al
In the intermittent use with power tools that these were designed for, these lithium iron phosphate cells could last that long, in theory at least.Wow, impressive claims about the lifespan of the batteries (8 years!!), maybe there is something in the A123 cells...
this one looks much more plausible, the space seems sufficient to accommodate 36V 10AH battery.I see these are due for release in spring 2014. $699 USD on pre-order. Less than 500 units left!
