Not worried about it - just don't agree. Looks like you've got a new build in mind and looking forward to seeing it. Thanks for your "interest" in mine.
WOW amberwolf, great stuff. What you propose should work and makes perfect sense. I like your tensioning solution as well. Also think your design elliminates the twisting and lateral force issue inherent in mine. Had considered that same approach just positioned differently. This motor...
HI Amberwolf, did not know the DayGlo project was your build. Read your articles in detail months ago - great stuff!
Good question. It's my understanding that a brushed DC motor can run backwards and provide the same torque+revs per amp. The controller is dictating the current either...
Thank you very much Bill. It can be done, and it works. You can do it too for not much $$. Smiles everytime you twist that throttle. Enjoy building your e-bike project!
Thanks Mike, and I agree. The bike is inside right now with new batteries, enclosure, and watt meter all waiting for my attention. Plan to allow for more airflow by venting the box at the controller. Great point.
The friction drive wheel is in motion when the bike is moving - so no freewheel. Pedaling is not hard depending on the pressure applied between tire and drive wheel. You can "feel" when enough throttle is applied and the motor "catches up" with the tire speed taking over. The shaft...
Thanks for the positive comments! Have 200+ miles on it so far and still thrilled when that brushed motor whine kicks in. Made a few minor adjustments before the really cold weather rolled in. Will take a few photos and post an update. Was getting a "safe" 6 miles out of the original...
This chart is posted next to our battery bank, which is vented outdoors for equilization charges (the smell is really something). Colder temperatures have a big effect on capacity. 100% at 77deg F, 80% at 32deg F, 50% at -22deg F and so on. I'm also using SLAs for the E-Bike.

Not clear how that series/parallel switch is converting 12V DC to 120V AC in that diagram. Would be interested to learn more.
The cheapest way to charge batteries solar is matching panel output to battery input w/o storing or converting. Go right from the panel to the batteries using a...
I'll jump in again. A good inverter will be 90% efficient. Check the specs on the one your considering. At that price, modified sine. Consider the output voltage range output (5% or less is good) and the no load draw (in amps) on the bank. Inverters are rated for max power (marketing)...
Great question. Honestly, if the panel voltage output is close to the 13-14 range (depending on amps), then you don't need a charge controller. Just need to pay attention to the system and disconnect when necessary. That link did not have anything about MPPT. If your thinking about...
Really looking forward to three wheeled electrics becoming widely available. 100 miles per charge changes things for sure. Had read about the ZAP http://www.zapworld.com/ and the NmG from Myers http://www.myersmotors.com/ and now the Arcimoto. Which, looks pretty good as well and thank...
Exactly. Something like this?
There's a few sizes out there. Here's a link to JEGS http://www.jegs.com/p/JEGS/JEGS-Exhaust-U-Clamps/751060/10002/-1 Will the motor bolt up tight enought not to twist?
