MIT Actually Reinvented The Wheel [video]

Hmmmmmm... https://news.ycombinator.com/item?id=6562683

It's expensive, and it's a retrofit.

There are hundreds maybe thousands of models of highly evolved e-bikes made in China that have better features and lower cost. In addition to having an e-bike specific frame design that takes battery weight out of the wheel, most of them have removable batteries, which means you can recharge them at your desk at work and they won't get stolen.

And I was thinking the CopenHagen Wheel was invented by Andy Botwin (Weeds series - http://www.fastcodesign.com/1665013/how-weeds-became-a-marke...)

I like this version because it's not a retrofit and easy to take with you (remember: these are theft targets):

I can't comment on the efficient of the different techniques though.

Wow- Digg? I thought we were supposed to continue to ignore/punish them into oblivion for eternity.

Wow, a digg link? I haven't been there in a long time...
