Sanyo Eneloop Electrically-Assisted Bicycle

Greetings, Friends. We had an alternative energy fair yesterday here in San Diego. Sanyo demonstrated their electrically-assisted bicycle bikes that they said should go on sale in here in the U.S. this fall. There didn't seem to be any discussion on the forum regarding it so I offer my quick 'n' dirty review. (My apologies for not bringing my camera! Here is a link with a picture but the bikes they were showing looked noticeably different: http://www.engadget.com/2008/12/01/sanyos-eneloop-hybrid-bike-has-basket-will-travel/ I guess these are the Japanese versions. The United States bikes looked more masculine.)

First things first, the name. They called it the Eneloop. I do hope they change that name.

From what I've read here, it is similar to the BionX system. There is no throttle. On flat ground, it gives you a 1:1 boost. Whatever energy you expend, it will expend the same amount. The demonstrators said that when you are climbing a hill, the microprocessor senses that you need extra help and will increase the boost to 2:1. We were in a parking lot and so we could not test this feature. The bike has that generic Euro-look which (for no good reason as far as I can tell) has recently become very popular in the States. It only has three gears in an internal rear-hub. (Personally, I would prefer far more but I think they understand their target market.) The demonstrators estimate that it will retail here for between US$1500 and US$2000. Overall, I must say I was impressed with the Eneloop. It was very enjoyable, should be very reliable given Sanyo's reputation, and could become very popular here with people who haven't ridden a bike in thirty years.

There were numerous e-bikes, e-scooters, etc. including a uniquely Californian creation called the Zuum Craft (http://www.zuumcraft.com) that resembles a snowboard / skateboard -- Kowabunga, Dude! The quality is getting much better, as far I can tell. A local brought his Vectrix but it didn't get too much attention especially after those who were initially interested heard the price (US$11000). My recumbent was very popular (although it hasn't been electrified yet) and I got all kinds of questions and requests for rides. My impression is that once I have whichever motor I wind up choosing coupled with a Ping 48-volt, 20-amp battery, my recumbent will be heads above all the available choices that were represented (with the notable and costly exception of the Vectrix -- but you can't peddle that monster).

One very refreshing aspect was that Mr. Middle-Aged-Paunchy-Suburbanites were actually buying some of the vehicles. One of the salesmen was so excited that he had sold two e-bikes, he kept telling everyone in the general vicinity. It will be so nice having thousands of bicycles out on the roads in the next few years. (C'mon Gas Prices! -- Up, Up, and Away! -- US$5.00 Or Bust By This Fall!)

I guess with the Eneloop name, they're trying to tie the e-bike to their battery line. Were these equipped with NiMH batteries?

Darned! I'm pretty sure I asked every other vendor there but I forgot to ask the Sanyo folks what they used. They claim a very long range in their initial press releases so you have to believe it is either MiMH or some type of Lithium.
 
Hi,

I live here in Japan and I thought Id give you my perspective.

There is no doubt that the Japanese have the brains and technical know how to build some great bikes, but the actual bikes themselves suffer from a massive failing. They are ALL way under powered - that's why I had to make my own.

My wife is 39kg in weight, which is pretty standard for a Japanese, this is one reason why their bikes are so underpowered - the market they are aiming at - ladies shopping with their babies on board. The gearing is also set so that basically it is impossible for them to be pedalled much faster than walking speed - again they don't want mothers on bikes riding fast on the path. The other reason is that the government stipulates that motors should be under 200 watts and only work IF you are pedalling.

So just for these two reason I think the bikes unless radically altered for the US market wont be very successful. Also important to bear in mind is that they get such long distances (theoretically) because the people riding them weigh a half or third of what we typically do.

That being said if they would just scale up their motors it would be fantastic - they ARE amazingly reliable with none of the worries that we have when we buy things unbranded made in China.

Actually, my wife has a panasonic bike just like the one above, it cost 870 dollars and it works great for her but me (at 100kg) it can barely get to the shop and back.

I do see some amazing looking electric bikes here though, I must take some fotos............
 
I was in Japan back in 1996. I really didn't need a bike there because all the train stations in Tokyo were within walking distance. Most everything there was within walking distance even the grocery store. Here in the USA, my nearest grocery is 2.5 miles away and I live in the city, too. When I lived in the country, the nearest grocery was about 9 miles away.

In Japan, you can just walk down to the grocery and get some stuff and carry it back in a bag. I guess if you didn't want to use a train, a bike would come in handy. Are train prices still pretty cheap in Japan?

Only thing I didn't like about Japan was how strict some people were. I was staying with a japanese family and they were very strict and had lots of rules. It was what I would call oppressive and I was glad to get back to the USA.

Sounds like it... FWIW I've been using Eneloop AA batteries in stuff like electric toothbrushes for months now and am happy with them. The only brick-and-mortar store I could find them at was (the late) Circuit City, and the only sizes offered were AA and AAA. They're supposed to not self-discharge and seem to have decent capacity (sorry for the imprecision). If they were made in larger cell sizes and were affordable, I'd certainly think about using 'em in our electrics...
 
Sanyo released C and D sized cells very recently. They look quite good in terms of capacity. However, they can't compete on price with the best LFP batteries (mind you, that's MSRP on the Eneloop vs bulk buy on these forums for LFP). Lithium is still a lighter weight as well.

I've started using Eneloops instead of conventional NiMH for everything around the house (and in my bike lights) and like them a lot.

Some video on the bike:

Batt in the vid labeled as Li-ion. All carbon frame apparently...

The Eneloop sounds interesting, but I've gotta have a throttle. Brainwashed by Speed Racer cartoons, possibly.
 
:shock: :roll:

627,900.00 JPY = 6,845.10 USD

That's alot of sushi for a 250w bike. But I will never forgive Sanyo for burying Birkestrands AC motor so I may be influenced by that.
