Flywheel Bicycle: KERS for pedal-pushers
http://www.gizmag.com/flywheel-bicycle-regenerative-braking/19532/
The Flywheel Bicycle has a continuously variable transmission in the rear hub. This is linked to a 6.8 kilogram (15 lb) flywheel from a car engine mounted in the middle of the frame. When the cyclist wishes to slow down, such as when they're going down a hill or coming to a stop, they shift the transmission to maximize the flywheel-speed-to-bike-speed ratio. This "charges" the flywheel with kinetic energy - effectively a mechanical version of what happens in an EV where a battery stores the scavenged energy.
Once they want to accelerate or climb a hill, they do the opposite - they shift the transmission to minimize the ratio. This lets the energy stored in the flywheel drive the transmission, giving the bike and its rider a boost. In a ride where speeds vary between 20 and 24 kph (12.4 to 14.9 mph), the system is claimed to not only increase acceleration, but to also produce 10 percent in energy savings.
結論は、10％のエネルギーセーブになると・・・

左のブレーキレバーを引くと、リアホイールとフライホイールが接続され、
フライホイールにエネルギーが蓄積されるようです。
駆動力アシストで使う時も、レバーを引くのだろうか。
システムの重量で重くなった分と、優位性とを比較して10％のエネルギーセーブと言うことだろうか。
フレームの三角形の中はデッドスペースなので、有効活用には良いかもしれません。
