Neuroticooler - drivetrain and geering test

This is to become what's known as a "cooler racer", or more likely, a "cooler cruiser". The high center of gravity, the awesome grip of the tires, and incredible torque makes it feel like a wild animal that wants to throw the rider off. This is the first vehicle I've made that really scares me. Before I deliver this, I'm going to have to reprogram the controller to calm it down quite a bit. A stainless steel Coleman 54 quart cooler will eventually go where the batteries are now, and the batteries will move elsewhere.

Specs: 48V, 300A system running an Alltrax AXE-4834, a permanent-magnet "Etek replacement" motor made by Mars of Milwalkee, WI, and 4 "mini" Optima Yellow top 12v batteries. Final drive ratio is low - about 4.5:1. The throttle is on the right thumb. I've fitted this one with a differential, which makes it corner and steer very nicely. Originally, it was thought that the handlebar configuration would be needed due to heavy steering effort, but that turns out not to be a problem at all because of the differential. There are dual hydraulic brake disks and calipers on the rear axle, but in Neurotikart tradition, the Neuroticooler's brakes aren't hooked up yet.

Yes. It's lighter, and geared a bit lower.

You might want to move the motor more to the center, there is a lot weight over the rear wheels. Or you can make the frame a little longer moving the batteries more forward. You can also adjust the mount of power going to the motor.

The frame will stay pretty much as it is, and moving the batteries forward isn't really a good option. What I did after shooting this video was reprogram the controller so max torque is only at 30%. Even so, I can't hold on tight enough to try to break the tires loose in a turn.

Aw damn, can't keep the front end on the ground. **Inner Child Laughs With Delight**

this is a cool build. if you dont mind me asking how much did it cost ? I'm thinking of doing something like this in the future.

This build looks amazing, and sounds like a jet at 0:32! You should try using a tilting handle to steer, like the new segways. It'll be like riding a scooter: tilting into a corner while having the stability of a 4-wheeler (although it looks like it wants to stay on 2!)

Keep up the great work, you have truly inspired me!

yea, 14,000 watts is a bit much for that skooter.......gawd :)

same here

[DarkSpireCloudHaven]

oh and put a little more weight on the front.

[DarkSpireCloudHaven]

other than that, this kart is kick ass. :D

first i would suggest putting the seat (when you do) a little high so it can measure up to the handles. second make sure next time you cover up the cooler and engine and what not with something good because it might scratch and spark while driving it. :)
