Thank you very much trikester for the email. I appreciate it.

By the way what exactly are the diameters for the different models? And are there 2 or three models of it. Like 33Kw, 40Kw and 50Kw

As of 2013, I have seen only two size drawings for the motors. The 75-5 & 75-7 have different dims. I don't know if another physical size was added in 2014.

It was confusing when I first got my Powertrain kit because the drawing I had for the motor turned out to be the 75-7 and the motor I got was a 75-5 (which is what I had ordered). Fortunately, having the actual motor in hand, I machined the correct mountings. So glad I wasn't working from the drawing but then I had the task of getting dims directly off of the motor (not always easy on a round object). Everything worked out OK.

So is there a noticable difference between the diameters of the motors or is it just the location of the mounting holes?

A Max RPM number, and an efficiency chart would be nice to look at.

I bought the 2013 Zero FX/MX drive train for converting my hombuilt trike from gas to electric but that was when Zero first started selling the "Zero Powertrain". Shortly after that they decided to not sell to individuals anymore, only to OEM customers. 

I think the company lawyers got concerned about the guys who were building electric ultralight aircraft and electric self launching sailplanes.

BTW - If you are newer here, I posted the progress of that e-trike project on this forum.

I have seen your video, electric is the best way to freely explore the World. As I hate to leave behind trails of emission and sound, and even a trail on the ground. I have also seen the video of the guy who used the Zero drivetrain on his ultralight. Amazing prospects, really.

20x faster charging than Li-ion - A 10 Kwh battery is 100% charged in 5 minutes
Energy density comparable to state of the art Li-ion
Long lifetime of 3,000 charge/discharge cycles (Li-ion's life is closer to 1,000 cycles)
Ability to discharge fully without the risk of short-circuiting and damaging the battery
Doesn't heat up, so it wouldn't require extensive cooling
More powerful than other batteries, operating at over four volts

Manufacturing costs that are equal to or lower than Li-ion
Very safe, reliable, and environmentally sustainable
Fully recyclable

it is another revolution coming up

Hi guys,

Below is a link to a new battery technology that I think will change the game once and for all and put a grin on everyones face.
