What is the best style of bike frame for electric conversion. I'm not asking about brands or quality of construction. The basic frame configueration is what I am asking about.
Henry111 said:I am new to electric bikes but really excited about the whole concept. I have a background in RC model aircraft, so I am familiar with batteries (smaller of course), ESCs (electronic speed controllers), small brushless outrunner motor and such. Of course, I am wondering how much of this knowledge will be useful as I move into eBikes?
Question:
In RC model aircraft Lithim Polymar batteries have become the only way to go. I am wondering if they are used much to power eBikes? If not, why not?
Folks, I think I am missing a couple of things here:grindz145 said:Spellcheck? Who needs em....
Henry111 said:Drunkskunk, regarding your use of 8 5SPs 5000mAh batteries. After some thought I think I see what you are doing.
You are wiring 4 in series for 74 volts (you said 72). Then you wired these two sets in parallel to arrive at 10,000mAh.
Have I got that right?
Yes?
No?
Henry111 said:I have on hand a 150A OPTO ESC from Hobby King.
Is this kind of controller suitable for eBikes?
Or do I need something entirely different?

! Not enough information to answer your question...
Answer 1: NO, assuming your talking about turning an ebike hub motor with a hobbyking brush less controller. No because of two main reasons 1. No current limiting built in to the ESC. You pull to much amps and set your ESC on fire.. 2. Designed for high RPM motors, hub motors are slow, kills the ESC...
Answer 2: YES, assuming your will be using a regular brushless motor and running it thru a reduction system.
Answer 3: Kind of, asumming you want to spend lots of money and go in to something like a castle creations ESC... very expensive... advanced configuration required.. is possible to turn a hub motor
