This is interesting ! ! !

Until now, the regenerative charging function, “Loop Charge,” which enables charging while riding, only recharged the bicycle battery on downhill stretches or during deceleration. In these situations, the electric motor on the front wheel switches to a dynamo in order to charge the battery. Charging while pedaling on flat ground was not possible.
 With the ‘eneloop bike’ SPL series, however, the new “Eco Charge Mode” for regenerative charging control enables the rider to actively charge the battery while pedaling on flat roads.

.. “Eco Charge Mode” enables efficient battery charging on both flat ground and downhill slopes. It is also a superior riding mode for reducing strain on the rider on uphill sections. Compared to the “Power Mode,” which uses the most battery power, “Eco Charge Mode” increases the riding distance on one charge by about 53%, based on the new industry standard riding pattern. In terms of battery capacity comparison, the new models can travel about 55 km on one charge, the furthest-class distance specification in the industry, offering energy-saving electric bike riding.

“Eco Charge Mode”: Example of charge efficiency on flat ground
By traveling 1 km in “Eco Charge Mode” over flat ground, enough electricity is generated and stored to travel about 300 m in “Power Mode.”

So now EVs can be partly charged using hydrocarbons-heavy food stuffs burned in inefficient meat engines that leave a trail of sewage and packaging as landfill?
Forgive me if I am less than excited...

wow ES the next pool of negative rants.. come one come all
 
looks like garbage!!!! I mean "this bike with change the game , for personal ev's, esp with this eco-charge feature!!!!!" tell me more!!!!!

Thanks for sharing the news about new commercial bikes available.

But I'm also not impressed by what is offered.
I think the public who buys an electric bike want to pedal less. I understand that with this mode, you have to provide 33% more power on the flat to make the bike advance + charge the battery. So I have to pedal MORE and be more fatigued with this electric bike.
I'll stick with a bike with a bigger battery which I can pedal less. And if I pedal, the range is extended anyway.

I don't have regen on mine and I miss it. I'm certain that for braking at lights and going downhill I'd recuperate some energy.
I more or less hoped to blow my controller going 48V to buy the new ebikes.ca controller with regen.

hehe... not a rant myzter... Just that they are claiming 30% more range... I'll guess with system efficiencies more like 50% more pedal effort to gain that 30% more range. Handy as a range extender I guess if you don't wish to stop and charge or can't affort the small incremental cost of a little larger batt pack. It's just that I can buy my energy also as electricity from "alt" sources that are pretty clean and very cheap versus some of the expensive slop I pour down my gullet as food energy (smile)

that is understandable Lock ..

I can see.. traveling uphill that would be a big factor but what about a down hill grade of 1%+, seems that would mean less effort in pedaling or even no pedaling at all.

I have been toying with this concept for the past year.. and my bike has no pedals.. oh and cost a grand less among other things
 
Comeon guys... this is the large imitating the big...

Many of the current online "real" ebike vendors, overrate their stuff right? How is Sanyo "reordering" the facts and omitting the info about being 30% more drag to pedal through...

Are we making assumptions with regards to their losses or increased resistance while riding? Could they be possibly using a single phase output and current limiting that output to just a few hundred ma... that would introduce little loss (compared with "REGEN PEDALING")...

The bike looks feminine I agree, but that's likely the market for this bicycle... give it a thought:

1.) Design is feminine, even if color isn't.
2.) Offers to charge while you pedal on flats
3.) Offers to flatten out major hills for you
4.) Check the side fenders to prevent any mess from getting on your dress clothes

Now that I write the major points I take from the picture, it seems more a design for women and commuters who are traveling to work in their suits (as I do occassionally)...

We all know the truth, pedaling with any real effort will cause sweat... so yea you keep the road dirt off but... you smell like an old jock strap 20 minutes after you get to work.

This one has me laughing at the big leagues as much as the Toshiba SKIB on the schwin bikes... 2G for a 15mph, 36v battery solution and...wait for it, 30 minute recharges - personally I'll stick with 300.00 of LiPo (15S2P) and charge it with a pair of $30.00 (60.00 total) 10 A meanwell brick (2 modified S-350-48s in parallel) for a grand total of 360.00 and since I rarely go past 60% use of the pack, recharge is about 40-45m. Full recharge would be a tad over an hour - oh well, have 2 cups of coffee.

LoL.. looks impressive though real chick magnet wherez can i getz me one of them!?!

The thing that bothers me most about the bike is that it is a fixed-gear bike, so the human power end of things must always be stuck in a compromise ratio, rather than finding what is most efficient for a particular rider on a particular road.

The *motor* is listed as having 3 gears, so *it* can be shifted for better efficiency (perhaps even does this automatically; the Sanyo site does not specify), but not letting the human power shift gears is just dumb, especially with such low assist levels (1 part assist to 2 parts human power).

So having to move the bike *and* charge the batteries is going to be pretty hard work that way. :(

And since it takes (presumably plugged into the wall) 3 to 3.5 hours to charge the battery, I doubt pedalling to charge it is going to put much into it at the speeds you could go with that fixed gear, unless you can manually change the motor's gear to it's lowest one to maximize the speed at which it spins relative to wheel speed.

They even list one spec as "derailleur" but there isn't one on the bike.

Since they say it has a roller brake in the rear, I doubt it's also an internally-geared hub, though of course you could always replace that rear hub with one that is IGH, that's a lot of money to spend on a bike that already has a $2200+ price tag.

It's also apparently a one-size-fits-all frame, which is a bad idea for efficiency, comfort, and preventing rider wear/injuries (even though there is less stress on the body due to the assist, you can still hurt yourself riding a frame that doesn't fit you; it's why my knees are worn out since I didn't know any of this until I'd been riding probably 30 years).
