Re: Crash Thread - lucky

Thanks e-beach! I certainly fared well compared to your crashes. I hope you've recovered from those ones. :es: Yes, at the moment my e-bike injuries have passed. The short-term memory problems from the head injure took about 6-8 months to pass. (and yes, I wasn't wearing a helmet. :oops: ) The hand...

Re: Crash Thread - lucky

Sorry for your crash! Crashing sucks! After being hit by a car on my bike, causing head and foot injuries, flipping my bike when I was cut-off by a car that made an illegal turn in front of me, causing hand and shoulder injuries and loosing control of my bike that caused me to whip my rib cage over ...

Re: Lead acid anyone?

IMO your problem doesn't have to do with winding resistance. When you get the time, post the make and model number. Also, glad you are now posting pictures. That will help.

As I said earlier today... Yes, I know the motor is good. I have run it off of a 12v radio control ESC.
I did it again today too.......
Ok, then lets try to reverse engineer this. What esc did you use? Manuacture, model, ect?

Re: What causes inner tube to stick to the inside of a tire?

I don't think I used soap when I last checked that tube. And the streets can get really hot in the dead of summer, but to glue the tube and tire together like they were rubber-cemented together surprised me.

What causes inner tube to stick to the inside of a tire?

So after 14 months I finally had a flat tire. That is pretty long for me. (That is somewhere around 5000 miles of riding.) But, when I went to remove the inner tube it was really-really stuck to the inside of the tire. I mean really-really stuck. I had to do some really hard pulling to separate the ...

Direct comparison is stupid. There are a million times more lipos in cirxulation for a lot higher demanding applications then lifepo4 can dream of. Unless one takes it to a percentage like, what percentage of lipo's sold catch on fire vs. what percentage of LiFePO4's sold catch on fire. :D :bolt:

Re: I'm looking for a hall sensor for Magic Pie Golden Motor

The Honeywell SS41 (bi-polar) Hall sensor is the one normally used in e-bike hub motor. Like TommyCat says, you could use a SS41F and it would be fine. Unless you feel you might be riding in hot conditions then for a few cents more you could get a SS41G which is rated for hot conditions. Either one ...

Re: What battery to choose after your last one burned your house.

My first impression is that you will need a lot of cells to make a good battery. Like 600 cells maybe? I looked at the data sheet and could not determine what the maximum continuous discharge would be. Somebody correct me if I am wrong, but maybe .5C? Like 2 amps per cell? So in my mind it would go ...

Re: Question about battery for Ebike

I wouldn't worry about a temperature sensor yet. Just get to know your bike and your riding conditions. If your motor or controller are too hot to touch, then they are too hot. Try to put your battery in the triangle of your bike frame. If it is not possible, then in panniers so the weight is low. I...

Is the motor installed correctly? If yes, remount the wheel so that your wheel spins forward. (spin the axle 180 degrees.)

Re: What battery to choose after your last one burned your house.

Yea, I have been thinking about those TO cells in a bike application. My cursory calculations are something like a 80 to 100 LB bike. The battery pack could be 48v and 40ah (20s 1p) and could travel around 75 miles with a maxim output of 400 amps to the controller. It could be fully charged in 6 min...

Ok ,I am a little late to the dance on this post, but to comment on the original question of "What type of battery?" I would say any kind you want. High volatility or low volatility isn't that much of a issue if you are charging outside in a reasonably fireproof containment spot. If you like that rc...

Impressive! I myself am over 16,000 miles on my motor, three frames and 4 forks later. However, your ride is far more rugged then mine. The ride itself is impressive, let alone how often you do it.

Re: Help- 48v 20ah battery not balanced.

If your cells are Li-ion then you do want 4.2v per cell. Are you sure your charger is charging at to at least 54.6v? The first thing I would do is to plug that battery into your charger for 3 or 4 days. If that doesn't balance the cells then something is wrong. Either the cells are bad, or the bms i...
