I'm glad you posted that - had seen this press release the past few days but kept forgetting to post it here.
Not much of a regen fan but if anybody could pull it off, I have to think Panasonic might have a shot? Clever that they kept the generator out of the drive unit.
Their eBikes are really good - I have an older NiMh and it's a smooth, sweet, efficient drive. Nothing else quite like it in the industry. Giant made a few models with the Panasonic drive and I don't think their owners will give them up.
I consider any bicycle with an electric or oil burning motor hybrid. My legs are usually good for a couple hundred watts - couple that to an electric drive train, I call that hybrid.
The questions begs - if you have oil, electric and your legs for power what is that, a Trybrid?
