Thanks for the post! Huge titanium balls. I wouldn't do that at half the speed never mind in the dark of night. I hope they kickass!

Hi Barry, In response to your leaving a patch when you use the regen brake; I realize that at that point you're busy watching the handling of the trike but by any chance have you noticed the regen current reading on your cycle analyst at that time (during regen braking)? My line of thought is that p...

Re: Giant Iguana commuter

Front brakes good! As a newby welder not so glam but should hold up. 1/4" steel bracket stick welded to thin wall front springer fork from a Trek cruiser. Works great! Now I just need to find a fender and replace the headlight.

Re: 48 going on 12... VDC that is

I wanted to use automotive lighting on my 16s 1p headway powered ebike. 48 volts nominal but as much as 61 when charging. I tried Lyens' adjustable DC-DC buck converter but I blew it up when I left it connected while charging. I found a golf cart DC-DC buck converter on ebay that had slightly higher...

Re: Giant Iguana commuter

1st photo is of the new battery cover and my winter dirt. It is made from 1/4" lexan. The stock was old and the paper wouldn't peel so I had to sand it off. I think I'll do it some more so the finish is more even. I can still see the balancing lights and the power light but like a bathroom window it...

Re: Ugly Motor waveforms

I want to plug in a scope to check out my stuff too! How much was your usb scope?

As for ideas, could the glitches in the phase voltage be the pulse width modulation of throttle control?
Some PWM never actually goes 100%. I don't know enough about the BLDC controllers though.

Thanks Dogman! Lately I have been trying to get my dog to run alongside the bike on a short leash. It almost works but makes me nervous. Any tips?

Just thought I would post my experience with a recent set of Prius batteries. I am using a set of 6 modules. The are from a 2004 or newer vehicle and measured 7.4 volts or better each when they arrived from ebay. I have been charging them with computer packs wired in series to give me some 53 volts ...

Lyen controllers are very popular. He sells them in a variety of sizes right on this bulletin board. Look under new stuff for sale. I might be interested in your old one if the price is nice 8)

I have been wiring Lobster pleasure boats (marine electrician) for 20 some odd years. These are the folks I get wire, connectors and circuit breakers from. Good folks.

Re: PUT TO THE TEST - 9 Continent - 1000 miles @ 99 volts

Has anyone tried to put little finned aluminum heat sinks under the side cover bolts? There would be some wind resistance but at 100v maybe not too noticeable. Just a thought.
