View attachment 6
By no means my trike is at this point is no ERT Death Trike or recumbents.com Yeller wright your name in the black top trike, but they were my inspiration
they all started out life as a KMX frame. and with some time and dough I can achieve that kind of performance.

Thanks to Alan from ERT and Matt from recumbents.com for having the balls to build their trikes and giving me the inspiration to build mine.
Alan @ERT for his great motors and controllers all his stuff is awesome.
Barent from West Coast Electric Cycles who has built some pretty mean bikes himself for His great batteries motors and controllers and always continuing to improve on what he sells.
Justin at Grin for just about anything that you could want for your builds and the genius behind the Cycle Analyst and innovator of new and better stuff.
Luna Cycles for their in stock most of the time Great 52v 50 amps continuous 70 amp burst 24 and 28 ah battery selection.

Back Story: My KMX is a used f-8 tornado SN# KMX0003666 it's a early model with 16 inch front wheels and a 20 inch rear, the lowest frame height for a KMX except for the kiddie trike (perfect) for what I wanted.
I prefer the smaller 16 inch wheels up front and I like a 20 inch in the rear, the 20 inch rear wheel gear ratio delivers extreme acceleration with the right battery even with the small 35mm motor.
I bought this trike as a Amazon return paid $500.00 and that is about all it was worth if that,
It was cheap but the frame was tig welded steel which is very workable for chop cut grind and welding on.
Which motor battery and controller to start out with was a no brainer for me I use the same motor controller combo that I have used on a lot of my builds it is a proven starting point for me that I know does the job.
I first read about this motor in one of Spinning Magnets articles https://www.electricbike.com/edge-1500w/ it sounded logical to me so now the shop has three of them that are used for different test scenarios.
My motor's are, one from LA ebikes and two more from ERT.
What I have found is that all EDGE motors aren't created equal, after close inspection they were different, In china they don't know what a edge is to my understanding, that is a name that was given to it in the USA, if you try to order one from the manufacture they only know it as a 205 35mm V2 and when you place a order you can have them made up in different ways, for example the Edge motor that I got from ERT had temp sensors in them, (you want this if you are going to run Hi amps), The one that I bought from LA ebikes did not come with a temp sensor and the faze wires were of a lighter gauge wire than the ones from ERT, I have not tried out Westcoast Electric Cycles new edge as of yet but Berent orders them with heavier gauge faze wires and these newer curved magnets which is supposed to have benefits, I will for sure give one of those a try if for nothing else than to satisfy my own curiosity, what I have done in the mean time is just up grade my motors with a motor harness from Grin Tech, 12 AWG faze wire, and put a temp sensor in the one from LA ebike.
Just a side note when all three of the motors were set up different one with very small faze wires LA ebike's, one with a
little bigger faze wires ERT, and the third ERT modified with grin's motor cable running the same wheels amps volts on the same trike the one with the Grin 12 AWG faze wires out performed the others, it would be sweet to snag one wright out of the box with all the bells and whistles a V3 version with dual set of Hall sensors would be the icing on the cake.
Bring it on Alan and Berent.
.
The controllers that I use are from ERT, 18 fett 100v 100 amp sine wave programmable.
The battery is a Luna 52v 24ah that I have used on other builds it does a great job, with the GA cells giving up 50 amp continuous and 70 amp burst.
