Best balance, best weight dist, power on the wheels that need it.  Anyone else think it's a good idea? srx660 |

That is the basis of what I have plans for (IN MY HEAD). Also like Mtntech's front drive for his Honda S2000 build. A Subaru rear diff upside down with cut CV shafts. Then Dodge Stratus A-arms, nuckles and cut CV shafts. Slide a thinwall tube over one sides CV shafts, weld the shafts together and grind smooth, slide the tubing over and weld again. Poof, a Subaru inner Dodge outer CV shaft.
I was looking for a Corbin Sparrow to do this to. But a Velorex would also work.
Martin Lyons has not shown his design of the single shock to be working that I can find. He is one of the Admin on the Facebook's Reverse Trike Owners.... page. I may go ask him over on the Facebook page.

In any EV build, you must budget the costs up front with the longetivy and costs of charging. If you live on a low cost per Kw area like up here in Washington State, $0.088594 per kWh for the first 600 kWh's and $0.107172 per kWh after. So it will take 3.5 years to pay it back compared to the same cost of Gasoline in the same trike using my Burgman 650. After that is almost FREE thru the 12 years lifespan of the batteries.
Do your frame build for the budget of batteries, spacewise, but make the frame big enough and strong enough to double or triple the batteries when you have more money to spend.
EV will grow on you real quick but you can spend well over $10,000 to $20,000 in batteries if you want extreme range and speed.

I really think the government should get on the electric bandwagon and make law's that support buying and re-engineering a nation wide electrical supply gird thruout The USA. Brazil made a choice to use alcohol to fuel their cars instead of gasoline. Now they are not tied importing oil to keep things moving. At the same time there are problems in the enviroment with using alcohol. I think that electric has the least enviromental impact than anything else except human power, but that's another discussion on it's own.

James, I could make a whole lot of political comments about this EV and our Nations infrastructure subject, BUT I MUST NOT!!!

The biggest problem with this design is that the ergonomics of the operator are sacrificed to place the motor on the longitudinal axis of the vehicle... the arcimoto is a fwd trike with a transverse mounted motor that would be very similar - I'm assuming they used what they could because it was able to be sourced from a supplier without massive tooling costs. Transverse motors and single reductions are the most common for EV's in industry - Miev, Smart EV, Tesla, Leaf, 500e, all examples that have transverse mounted motors/transaxles.
If you are smart about sourcing your EV components from a donor vehicle such as a leaf, Miev, or 500E a person could very easily build an electric RT for under $10k - making it light and aerodynamic you could take the range well over 100 miles from those donor vehicles. If I needed to replicate the CozE, it would cost me around $4000 in parts before labor to put it all together. Were I starting with a donor vehicle, though, I wouldn't build an RT because you just can't beat 4 wheels! The only reason I build RT's is to license a built from scratch vehicle as a motorcycle - WAY easier in Iowa.

It is my opinion that the best drive train for an electric reverse trike would be in wheel motors for all three wheels with the motor controlers in close proximity to each wheel and linked by a computer.
I would have the two front motors 50 to 60Kw each and the back motor 100Kw so if you wanted to burn up a back tire playing around once and a while you could.

Just the controller to control 2 electric motors is very costly, for three motors would be well outside of my budget. But two EnerTrac dual 602 hub motors up front would be much more than what I need.

There are other options other than the EnerTrac motors.
I am also looking at paying a man overseas to design me a motor and controler for a couple of thousand dollars that I can build myself and modify it a bit if I felt so inclined to do so.
Such as adding internal water cooling and being able to bolt the wheels directly to the motor.
There is also another person who has reverse engineered the tesla powerplant and is selling boards and parts lists for the controlers so there are multiple pathways that can be taken.

I know a guy that has a Tesla Model 3 AWD with the larger battery for touring. His 0 to 60 MPH is around 4.25 seconds. He is waiting for someone that will give him total control so he can hit "Ludicrous" mode like his older Model S.
Zero Motorcycles told me about 1 years ago they were going to sell used motors and battery packs from doing up grades. I have not seen any of that yet.
The Zero uses two belt gears to give a 4.40:1 reduction ratio. Hub motors do not have this reduction so cooling is very important.
But if someone does come to market with a strong hub motor that will bolt directly into a Chevy Corvette mag wheel I am sure it will sell very quickly.
