Re: What Electric Automobile do you drive? Picture thread!

52 Ford F-1. At various points it's had a direct-drive warp 11, 11/AC-51 AC/DC combo, and now it's just the AC-51 with a 5-speed. Working on modular battery setup it will share with all other vehicles and solar house. 11856367_10155945690805182_7504912327903463623_o.jpg Tesla 85. Great, but too expe...

Re: Hybrid Motorcycle - Replace Stator with Brushless?

I second just re-using the stator. It's already mounted, it fits the space, and it's not a whole lot different than a brushless motor. They make permanent magnet upgrades for them. You'll want to do that. Then you'll need to rewind it for your chosen voltage. Next comes a 3-phase speed controller. Y...

Universal Battery Module for Solar, Lawn, Recreational EVs

Every tool/vehicle I own has been converted over to electric operation. I don't need to explain to you guys why, the smooth silent power of an electric motor speaks for itself. I have a zero turn mower with twin motors (one cut, one drive), a vintage wheelhorse garden tractor, a small narrow-deck ri...

You could use a boost DC-DC converter to charge straight off the panel:

Re: 2011 Zero specs / images released

The MX version of the Zero that Black Arrow was asking about runs an Agni motor, which is, I believe, a bigger diameter than the old Etek.

Switching to brushless motors has to be the next step, as although there's no doubt that the Agni is a great motor, I can't help but think that a brushless motor would refine the bike even more.

Re: High speed ebikes. Why?

I use speed to keep me safe. 19 out of 20 bicycle fatalities are impacts from behind (IIRC). I keep up with traffic and don't ever give them that chance. I have removed getting passed constantly by motorists who don't respect my right to use the road from my cycling experience.
