The RC version of my dream ebike will come in the form of a KMX trike with multiple motors, a quad 3210 maybe ? would sound freakin great...!
Bottom line, I can only do as much as the budget allows. So with that in mind the next thing is lipo .. then i'll get back into the drive adjustments ! Unfortunately the RC bike is not the only project on the go.. gulp..

*reminds self he has an Agni 95 Reinforced and a 72v 500 amp controller on the shelf !!

HE IS THE SICKEST THING I SAW : ): ....
TODAY I WILL SEE HAL AND WE WILL TRY TO TEST IT. HERE ARE THE PICTURES . MOTOR CONSTRUCTION LOOKS OUTSTANDING
THIS MOTOR IS MADE FOR INDUSTRIAL APPLICATION FOR SURE , HE IS NOT SO LIGHT. HAS AROUND 5.5KG .
DEFINITELY HAS A LOT OF SPACE FOR AIR FLOW ON UPPER AND DOWN PART OF THE STATOR.
HERE ARE THE PICS : SIZE COMPARISON WITH CIGARETTES AND AGNI

How about 2 of these these (or maybe 1) 15kw RC outrunners Hal and Marko are working on?
Sensored, water cooling (optional), 5.2kg per motor, priced at about $300 each, designed to be connected in multi-motor configurations:

The drive part of this is really pretty simple. There's separate chains to the rear for the motor and for the pedals. Both rear sprockets are attached to the SRF-3 hub, via a standard Nexus 16T splined steel cog (also available at UtahTrikes.com...). I'm using a Nexus cog because they are dished slightly, which helps in the alignment of the chains. This steel cog is sandwiched between a 22T 4-hole 64mm BCD "granny gear" aluminum mountain bike sprocket, and a 94T aluminum #35 heavy duty go kart sprocket I got from gokartgalaxy.com. This sprocket already comes with a 2-1/8" hole and four holes in a compatible 64mm BCD pattern. The 16T cog lines up perfectly, so it literally just bolts together. I used some small 3/8" wide spacers I got from McMaster, to space the two sprockets apart a bit. This assembly then slides onto the splined hub and is held in place with the circlip. The big #35 sprocket is on the inside. The 22T sprocket ends up being perfectly aligned with the chainline coming from the crankset.
To keep the motor from driving the pedals, I replaced the front crank with an IPS crankset, which has an embedded freewheel. I'm having some adapters made, however, that will eliminate the need for having to add a FW to the crank. The adapter will replace the 22T sprocket with threads that will allow a standard BMX freewheel to be screwed onto the adapter. These come in sizes from 16T to 22T, so it will be easier to match a stock setup.
