    Could a 9c motor fit into something like this?

    The build is going to be easy. Training a monkey to ride it is the hard part.

    Anyone voting for Romney after hating on EV's in debates?

    Philistine I'm on board with everything but bangers and football. You are one back-dated Hawaiian birth certificate from getting my vote. I would add one item to your list: Cut income taxes 10 percent across the board, and raise fuel taxes enough to make up that difference plus $100 billion per...

    Stealth Cruiser

    You should not be sitting on your seat while going down steep hills offroad. Stand on the pedals and push the bike out in front of you. I think you're vastly overestimating the chances of going over the handlebars. The weight distribution on a cruiser plus rider is about 35/65 front to rear...

    Minimally invasive 9C temp probe surgery

    Doh! The computer wires are inside the motor. One consequence of using the shorter "stick the meat once" BBQ probe (as opposed to the longer "stick it and forget it" probes that Doctorbass pioneered) is that I had to run the extension wire to within about three inches of the actual temp sensor...

    Melted my Anderson power poles together

    I had the same thing happen with my iCharger 106B. I put an Anderson on the wire between the power supply and the charger, so that I can quickly convert to the 12-volt car battery clips if I ever want to charge off my car (which I've never done). The Anderson melted, the charger threw an error...

    Temp sensor that's too cool not to share

    So in the spirit of answering my own question, I gambled $10 on a cheap BBQ thermometer, hacked it to bits, and installed it in my 9C. I have declared victory and put the play-by-play and pictures here. http://endless-sphere.com/forums/viewtopic.php?f=30&t=44110&p=642296#p642296 I'm happy...

    Minimally invasive 9C temp probe surgery

    Okay, so I tried Amberwolf's suggestion and it seemed like it was going to work. I pulled out the silicone at the base of the axel and pushed a clotheshanger through from the outside. I got enough depth, but couldn't get it to turn the corner. After half a dozen tries, I switched to 14 gauge...

    Zip if you have a motor that runs on sensorless I can lend you a spare controller for a week or two.

    First build help: Know the kit I want, but which bike?

    Great build.

    Ra-Roh!

    A follow up to this little episode. I PM'd Methods to ask what kind of cap to replace the blown one with, and he offered to do the repair for free. He's really a stand-up guy, especially since there's a better than even chance that the cap blowing was a direct result of me doing something...

    Temp sensor that's too cool not to share

    Anybody hacked something like this for a motor temp probe? Looks like the business end is similar to Doctorbass's BBQ probe, with a display that's smaller and will read in full sun. Temp range is right too...

    How difficult is basic frame fabrication?

    I've been thinking along the same lines. Drift trike with a 2810 9C in a 20" wheel (just got the motor yesterday) and 24s lipo. Yeehaa! The chopped BMX front end/square-tube rear method seems pretty simple. This kid did it in a day and a half for about $40. Now, put a controller and a layer of...

    Minimally invasive 9C temp probe surgery

    Two good options and a reality check. Great responses guys, thanks. I'm going to stare at it for a couple hours, maybe try Amberwolf's plan first and if I can't make that work I'll either fall back to John's option or just end up ripping everything out and doing the LFP phase mod. To be...

    Minimally invasive 9C temp probe surgery

    *Edit* I took John in CR's suggestion to wire a temp probe through the right side axle. Scroll down for the play-by-play. I always wondered how doctors could start a tonsillectomy and end up removing somebody's spleen. Now I think I get it. I opened up my 9C to install a temp probe, and...

    Battery Packs - Where to buy them

    Second what Dogman said about lipo. Get Icecube57 on the forum to make you a battery/wiring harness and give you his shopping list for lipo bricks and charging apparatus. Then you literally just plug the batteries into the harness, and away you go. Ice will send you a YouTube video to talk you...

    72v 1500W 40A Hua Tong CA08 XM06AD_P04.1 controller

    Haha, thanks. I'm gonna hold out for that nickel, dammit. Seriously though, are the 30-something dollar ones long gone?

    Anybody seen these lately for less than $47 landed in the USA? Best I've found today: http://www.aliexpress.com/item/72V-1500W-Brushless-Speed-Controller-for-Electric-Bikes-High-Quality-OT100/287758466.html

    Perfect. Then you don't have to stop to pee.

    Yeah, got it rolling for a week then blew it up! I have a pre-charge resistor for you, no sweat. I'll roll up there this weekend if I can bust loose for a couple hours. Baby Beachcruzer is due in about three weeks, so free time is limited and about to be nonexistent for a while. Would like to...

    Ra-Roh!

    Thanks Amberwolf. Any suggestions for where to pick up a good-quality 100v/100uf cap? Google comes back with hundreds of them and they all look exactly the same. Also, any point going to higher voltage or uf?

    Ra-Roh!

    Okay, step one was to plug the pack into the eBike that still works and pick up six of these. Here's what it looked like on the bike after I plugged in a 98.5 volt pack and BAM! Note the blown gasket. Here's what we're dealing with. GrinTech 6 fet 4110 modded by Methods to 40 amps...

    Ruh? What's that Scoobs? Why didn't I just got a harness from Icecube57 with a precharge and fuse prewired? Good question . . .

    Ra-Roh!

    Thanks Amberwolf. Didn't think the order or on/off mattered either, but wanted to identify everything I did differently. I'll open it up when I get home tonight, and post some pics. Any recommendation of what to clean it with? And what's the deal with capacitors? Can I open it up and solder a...

    Ra-Roh!

    Thanks Amberwolf. We had some chicken on the barbecue when Scooby posted that. I guess he was distracted by the smell so he posted to the wrong forum. . . . I've done some stupid things with eBikes but not a polarity reversal (yet). The power wires to the controller are shrink-wrapped together...
