Looking for an electric bike that does the pedaling for you? You have plenty of choices
, particularly if you're willing to drop over $2,000, but finding one that uses regenerative braking to extend the life of its meager on-board batteries isn't so easy. Panasonic's Vivi RX10S
is about your only choice until February, when Sanyo's new eneloop-branded bike is set to start pulling weak (or just lazy) Japanese riders up up inclines before recharging itself on the way back down. On a hilly course a charge is said to last about 35 miles without braking, 46 by charging only when braking, and 62 miles in "auto" mode (charging on downhills, too). If you live in Japan it'll be yours for 136,290 yen, about $1,450 US -- but if you live around here we'd recommend not canceling your spinning class just yet, because while Sanyo pledges to ship this elsewhere in the world "at some point in the future," it could be awhile before this thing starts hitting the diamond lanes near you.
