Re: First ebike

My original thought for the 8T was based off this thread , but at 48V it seems like the 10T is the clear winner especially considering that 30mph is plenty fast for it not be clearly visible as over the legal limits. That's also the thread where I found the 2000W for ~30min max on the MAC motors, w...

Re: is my ebike really environmentally safe?

That's some pretty serious wear there. You could take a cheap lazer pointer and run a line down the center of the bike and see if everything is straight. I would expect a tweek in the frame or triangle might make your tire wear a bit more quickly as well. Still like others have said nice sticky tire...

Re: Help with computer motherboard repair?

Sorry missed your reply. Many motherboards require the CPU fan to be hooked up they won't stay powered up as doing so even for a short time without a CPU cooler will toast many CPUs. Were it me I would put the cooler on, hook up the fan ,a keyboard and a video screen of some sort. Then see if it wil...

Re: regen thought, probably wrong

With a motor running and you pedaling the energy you put out will be far greater than the energy you capture using regen. Motors are halfway efficient these days often 80-90% in the correct rpm and load range. Regen and generators not so much. They must be fed much more energy than they are capable ...

Re: I think I need new grips

Some grips are quite pliable and soft. They don't last as long but are far more comfortable. See that you feel them in the stores before you buy. Padded gloves help as well I use the weightlifting kind in summer as they have a mesh back that does not hold heat. Got suspension and fatty tires? Once I...

Re: What's a good red rear tail light for e bike?

The planetbike superflash series of rear lights are very popular, very bright and easy on the batteries. You can use rechargeables if you need to be green. After a few months on the road at night I found these. Have not used anything else since. http://www.biketiresdirect.com/product/planet-bike-sup...

Very nice build you have done. On my first build I put my controller in a metal box and had no problems with it overheating with the 25A max I ran through it.

Re: Shunt mod on em3ev Infineon?

The com port in your computer must match the port you tell the program to use or you will get nothing. The controller must be powered down/off as well. I had to get past both of these before I managed to get the program to run and change the values. I wish you luck.

Acceptable to who? There are many I would expect who might answer the spoke angle is acceptable if the spokes do not break.
