What glue is between them?

That seller has almost 700 feedbacks and 98.8% are positive. I asked did anyone bought batteries from aliexpress.

There (on aliexpress page) is written: I got answer about "for". It looks strange. Other sellers does not write "for". They write genuine. Did anyone bought batteries from aliexpress? They are there much cheaper, then in my country.

Fasttech does not send into my country, it lies, on product page is written: WORLDWIDE FREE SHIPPING But they does not send into many countries.

There are something strange in aliexpress and alibaba. For example this product page: http://www.aliexpress.com/item/18650-US18650VTC5-3-7V-2600mAh-high-drain-30A-discharge-vtc5-battery-for-Sony-power-tool-makita/1872913567.html In title is written: "for Sony" What word for does mean? In...

Backward.

I keep my e-bike at home, i lift it by elevator (i live on 8:th floor). If i will keep it in public bicycle storage, then someone will stole it quickly, there (public bicycle storage) is cheap bikes only.

50 degrees was outside. I don't have laptop.

Here is typical bicycle lane in helsinki: http://goo.gl/maps/zkGVB Today i saw 2 police cars during ride :) Police mans also saw my e-bike, i did not ride overspeed at that moment, because i explored helsinki at that time. Here helsinki's one of the best bicycle lane. http://goo.gl/maps/Iyd1w...

Is crank this:? I am not englishman, my native language is not english. If 50 nm on crank, then on wheel must be about 35 (crank's and wheel's biggest gear ratio is about 1.5) 35nm on wheel is too small torque. My weight is 87 kb, bike + batteries 37 kg, whole weight 124 kg. When i want ride...

Where you read about it? Is in this forum topic about it? 50 nm where? On crank or on rear wheel at fastest gear? How much bosch costs? Is it silent? Helsinki. Not perfect, it's speed at 36.5 v on flat is 33 km/h. EU legal is 25. 12T's maximum speed on flat at 36.5 v with 26" wheel is 27 km/h...

I don't want euro legal, i want overspeed, but i don't need heavy overspeed. For euro legal 12T is better with 12s lifepo4 battery, because it has maximum speed on flat 27 km/h, 10T has 33 km/h. According data which i got at 36.5 volts 33 km/h on flat. Difference between 10 and 12T is small...

I know, peddling impoves efficiency greatly, but if i ride over 70 km, then i can pedal first 40 km, but last 30 kilometers i want to rest. 31 mph = 49,6 km/h, it is very heavy overspeed, almost double overspeed. 49,6/25=1,984 I have this battery...

Not big, but my current crystalyte HS2540 is too bad for them. 15-20 km/h. 100-400 meters. It has worse power/torque ratio then 10T, and too big RPM/volt ratio. 30 mph = 48 km/h. I live in EU, here riding on e-bike over 25 km/h = overspeed. I can ride overspeed, but slight overspeed only, 30...

According simulator BMC v2 torque has 1,42 times less RPM/v ratio then speed version. If they are copy of 10T and 8T then ratio difference must be 1.25 (10/8), but it is 1.42. Why? If i understand electromagnetism correctly, then torque version must have bigger amount of copper then speed...
