How to connect a phone or other gadget to the Intuvia Display: Into the Intuvia display goes a "micro-a usb" Into your phone goes a "micro-b usb" (newer android/gopro/garmin/etc.) Here is a couple of links for this specific type of cable...

I know so :-) First of all we are most likely dealing with Aluminium 6061-T6. Go above 225 degree Celsius and the hardening begins to weaken, raise the temperature and it goes faster (it's also time dependent). Go above 530 degree Celsius and let it air cool and it's gone. After normal welding...

There still appear moist inside the LED readout after a rainfall, and I haven't found a way to open the battery. So until get it opened I don't know if it has any influence on the battery.

I went to the dealer and got a new remote on warranty. And after the first rainfall that one doesn't work either. This part is simply designed wrong.

The bike and battery has been running 6000km now. So the bike went to the dealer for some maintenance (oil, brakes and things). Here I asked for a data read out of the battery. It is not an impressive amount of info that I was given, but the total amount of delivered Ah to the motor is a nice...

The answer to why your bearing broke down so quickly, could be that it is Chinese. Now before anybody begin to throw stones at me, listen to this: The official explanation from The Danish Technical University - Mechanical Institute, is that the difference between SKF/FAG/INA and Chinese...

Found these pictures on ebay http://www.ebay.de/itm/Bosch-E-Bike-Akku-Pedelec-Akku-Powerpack-400-Lithiumakku-/141573699804?pt=LH_DefaultDomain_77&hash=item20f67338dc

Interesting that it's first time you see these threads, you have posted in all of them :lol: It's 15Ah pouches. And the BMS isn't worth fixing.

The picture of the Sunthing28 early in this thread is identical to my Sun-thing28 battery, I bought from him a year ago. It was a 48volt 30Ah, in blue plastic and white foam. The BMS is different, but so is the capacity. Here are threads with the same battery from Sun-thing28 and pictures of...

No one but you can put your mind at rest! It can be many things and nothing, finish the conversion take a few rides, and see if it continues. Use some time on the "problem". A few weeks ago I got a weird sound in my bosch center motor after a few days it disappeared. The same thing happened...

I won't recommend doing this Bafang BBSxx conversion if your frame is aluminium. The most straight forward conversion would then be to lace a hub motor into your 24" rear wheel. 500watt should be great and 1000watt awesome. A conversion with two hub motors in the front wheels has been done...

I thought about writing about the Christiania bike in more general terms, and then found this excellent English written history on the homepage of the Christiania Bikes company So here it is, from the companys mouth: Information and picture taken from: http://www.christianiabikes.com/en/

On the right side of the diagram there is a summary of max torque, efficiency, speed and power.

No, I bought mine from Amy (can't remember the company). These Motor Characteristic Diagrams are worth gold if anybody want to optimize their bicycle gearing. But the diagrams are scattered over the Internet, weird that Bafang isn't doing more on suppling these information to there audience...
