It uses a small but heavy lead-acid battery. That equals low range (30 miles would be like the Leaf's 100 mile range), high weight, and lower performance. This thing seems to be a solution in vain search of a problem.
Really? I saw the spec on their website and it says the battery is rechargeable lithium, not lead-acid. Why do you think it's lead-acid?

Do you need reading glasses? ;)

Oops, no - I read another piece on it that said lead-acid. Either it's available with both or one of the articles is wrong. Anyway, the idea of putting the battery in the wheel has problems - mainly the range and power available. The US version is 350 watts, and that's kind of anemic for a hubmotor. A geared motor could work with that little power, but unless this has both a battery pack and a transmission in it (unlikely with regen), it will most likely underwhelm.

Man, this site can be a PITA, especially finding and posting to older topics... anyway, has anyone else been doing Winter riding? I have bad circulation, so I go out wearing two or three layers of clothes (including two pairs of socks), electric inner soles, electric lithium powered heated gloves, and a pair of foot warmers on my inner socks. Oh, and a ski visor over my heavy balaclava. ;-) It's quite rewarding, though, cycling past snow and ice-covered fields, and watching the deer, eagles and other wildlife ignore me. It's getting a bit old doing it like this in mid-March, mind you, but I can still get 10-14 miles in. Still, I will definitely be welcoming Spring!

You have my admiration for your dedication and my sympathies for the cold weather. It must be beautiful out there in the snow, though.

Though we have drought and earthquakes, and sometimes bad brush fires, winter riding here on the left coast is generally pretty easy. I've been riding almost daily, but all I've needed is a windbreaker on some days. We're already enjoying Spring, and my favorite canyon destination is greening up quite nicely.

Ride on!

If I had a photo to post, you'd swear it was still January here. The Hudson froze over then, thawed last week, but above Lock 3 it refroze this week!

We had a heat wave come through Michigan yesterday. It was 39F and I broke out my eBike and rode to work. I need to find my headlight charger though. Riding in the dark isn't fun.

That's why I like AA/AAA battery lights. Easy to carry spares.

Does anyone here know more about the GoCycle G2R folding e-bike? http://www.gocycle.com/category_s/90.htm
It's only 34 lbs and does 40 miles on one charge. Best thing, it's foldable.

I read some articles with a bit of google but I can't find anything about purchasing it in San Francisco.

Their web site doesn't show any licensed dealer in the U.S., so probably pretty difficult to get it here.
