That's a cool design. I'd like to know more about it's biodiesel generator. Diesel generators aren't exactly small, so I'm wondering how they did it. I wonder if they took something like the diesel that was used in the Smart FourTwo, and modified it.

I would contact Traxial motors (subsidiary of Magnax motors), and see if they have a solution for you. They make some pretty powerful small axial motors. At worst, they could simply be out of your budget, or not work in your case. But it doesn't hurt to ask!

Anyone here happen to know the Vector Vortex battery box internal dimensions? Need to know what size battery I can stuff in there. I emailed Vector, but I'll probably be waiting a while for them to answer back, so I figured I'd ask here in the mean time in case anyone knew, and I don't have to...

Does this controller have the ability to daisy chain, so if you had 4 motors, and 4 controllers, you could connect the throttle to one acting as the master controller, which would send data to the other 3?

I was wondering if you ever found any of the 21700 honeycomb style holders, I'm looking at building a battery myself, but might end up having to use the half-cell holders in order to get that staggered design.

If you are willing to spend the money, you could use the BMS24T from Chargery. It supports up to 24S, and up to however much current you want I believe. It uses 1 or 2 external contactors (relay) to control charging/discharging. So for 500A, you would just need a contactor that can support 500A...

Are you taking possible feature requests? There is a feature on the Mobipus controllers that I'd like to see on a PV controller. It's called Auto FOC I believe. AFAIK, it works like this, as soon as you hit a certain speed (as programmed into the controller), it will automatically enable FOC so...

When sealing it back up, use RTV silicone gasket, you can get it at any auto supply shop. Also, while it's open, maybe think about adding some statorade if you haven't, it will help keep the motor running cooler.

I'd like to know what front fender you are running on the bike? Been looking for one that will fit USD forks.

Mobipus 72200, you can get them over on Ballaratebikes.com

Will you be driving this in the winter? Because it seems kinda low for snow, or speed bumps, lol. Anyways, for the motors, you should check to see if Revolt can do Halbach Arrays with the magnets. It should increase the efficiency of the motor, and higher power density. Might cost a bit more...

Depends on how you want to set up the bike. Do you want a mid-motor with sprockets and chains (or belts and pulleys like Zero). You have less space for batteries, a con, but also have less unsprung weight, a pro? Or do you want a hub motor with no sprockets or chains, more space for...

Actually I'm not. Halbach array motors can be ironless, so you don't need rotor iron or stator iron. So no back iron or laminations. Here is a company that makes such a motor > http://www.launchpnt.com/portfolio/transportation/halbach-electric-motor Supposedly TFT FlightTech use an ironless...

I'd like to see some more halbach array motors. Yes, they are more expensive because they are more complex to put together, but they are much lighter because you don't need a metal armature core, thus no laminations. So you could have very, very, light rotors. The weight would be mostly from the...

I would do what Tesla does, have individual fuse wires going from each cell to a bus bar. https://endless-sphere.com/forums/viewtopic.php?t=79950 https://endless-sphere.com/forums/viewtopic.php?t=88039 You will be able to size the wire better, and get much higher currents, than if you use...
