Custom/Hybrid When will it begin?

[Billybo455]

unless the new compressed air setup is ridiculously efficient i don't think that's realistic at all. I have a 150 gallon compressor in my shop. just walked back with my 1" impact and my tank full at 165lbs i could drain it in under 3 minutes. now for a tank that can hold 2000psi in carbon and to have any size would have to be 1-2"s thick depending on tank size. people already look crazy at us florida boys when we take out our 30k ski. could you imagine the cost of this?

Do some reading on the website, you are compring apples and oranges. Air tools are extremely ineffecient, do you feel all that air coming out the exhaust of the tool while you are using it, most of that energy is being wasted. ENGINEAIR is claiming 94% efficiency for their engines, MDI cars in France are already set for production, they are however running a different type of engine.

They are running carbon fiber air tanks running 300PSI and tested to past 700PSI, You could run two steel tanks down under the tray where the exhaust and scuppers used to reside but then there is the weight issue to deal with.

Range on the air powered cars is around 75 miles on a fill of the tanks, the tanks refill at a charging station in about three minutes, with a booster you could refill this at a gas station or with a compresser mounted in your tow vehicle in a few minutes. While you are standing around BS'ing like goes on at most freerides, your ski would be recharging.


All we need this thing to do is go 30 minutes between recharges, the cars are going 75 miles pushing a lot more weight, think about how you are using power in freeriding, a lot of off throttle or part throttle usage with occasional bursts of power .

Now look how much space you just created removing all the subsystem in the ski, most of that space is now available for use as an air tank, hell make the air tank go completely around the engine and from nose to tail of the ski.

Its the same weight issues you deal with already. if you want light weight you have to go carbon fiber, This technology-carbon fiber tanks is already widely in use with natural gas powered systems.

Electric this electric that ......... maybe we should ban all the huggers ?

Neat technology , but these ASS HATS will never be satisfied . Electric or not , trail riding causes erosion . They just closed down a MTB trail that was there for 25 plus years ( perfectly ridable have been riding it on and off for 20yrs ) In addition they closed the Tellico ORV area . The federal GUBMENT owns 30 % of all the land in the country and the huggers gunning for every ORV area on grounds of erosion . Electric skis will disturb nesting birds , fish migrations , bank erosion any thing they can come up with to restrict access .


Please refrain from posting any more trail riding electric or not . Every time I see roost coming off the rear wheel , I can only think of how our mother earth must be screaming in pain........ please STOP the violence against our mother . I think I'll take the day off to get stoned and find some sort of environmental anti something to support.

Just join the Occupy XXXXX protests with the rest of the hippies. Most of those douche bags have no clue what they are protesting for or against, at least you do.

Thousands cheaper than the KTM, available in North America and lasts longer on a charge;

Not to mention quite a bit lighter.

Did anyone get the idea that its called freeride, because you can take this thing just about anywhere? There's no laws saying u need it plated, registered etc. Actually, correct me if im wrong but the same rules that apply to bicyclists would apply to you. Which means I can ride my dirt bike through the park without being blasted by authorities. (unless im destroying the land). I like this idea, for where I live I can be absolutely wreckless with this thing. Also, there's no where to ride dirt bikes on long island. Forget it, if you found a spot .. They WILL shut it down. No point in owning one here. Nearest area to go riding is upstate or out of state. There's a track here but it's not a friendly place for the occasional recreational guy.

One major turn off there, it's a cluthless one speed. It just would never be a true dirt bike feel, and one gearing is going to be VERY limiting. KTM shows a concept with a plate, im almost positive they have a gearbox figured out.. Oh wait, I see a clutch.

I paintball and the tank I use is a carbon fiber tank that 4000psi and 60 cubic inches im sure if you made a big one similar to a paintball gun tank this could possibly work.

that electric bike is still illegal to ride most everywhere. it is a gimmick. you try to take it anywhere that ISNT designated for OHV use and you are looking at fines or worse. not to mention in places like cali where they have the red sticker/green sticker nonsense, The EPA out there isnt going to wanna hear: "but officer, it's electric". it'll be here's your ticket and court date, please see the impound attendant to get your vehicle back. have a nice day.

My solution is a compressed air driven ski, the motor is already being built, an Australian company holds the patent on it. The problem is this company wants to sell rights to the engine and have you make it under their patents. That is going to require deep , deep pockets.

Here is my sales spill, there is no exhaust, intake, carb or electrical system as its not needed, there is no need for venting or air intakes in the hood as the engine is self cooling like an air ratchet. This means the hood can have an airtight seal, no bilge system needed. There are no holes going through the hull except for the driveshaft and steering cables. There is no fuel tank, fuel lines etc. There is no need for flotation as the area under the tray and parts of the engine bay are now a compressed air tank. There is no pollution from the use of the ski nor any sources of ignition in the ski. There are no electrical components in the ski. The air gauge is mechanical and simply reads the pressure in the tank. The throttle cable operates a mechanical air valve to vary the throttle settings.The hull is built from Carbon fiber, partially for light weight but also because carbon fiber will hold an enormous amount of air pressure if the tank is made properly. The carbon fiber tank will not explode if ruptured it simply releases air pressure, no harm no foul. The downside will of course be run time, if you can get 30 min run time though you have the same run time as most high HP skis. The ski should be crazy light since you have eliminated all the sub systems required to run a gasoline powered engine. Power to weigh ratio replaces HP, end user product is still very fast and very light, the engine weights 25lbs and starts rotation at 1psi.


This is not a dream the engine is already being produced.

yea been produced. i heard thats how they ran the skis in waterworld to avoid dealing with epa on the set off monterey.

Bump anymore info on this?

In my world my ski will always run on old dinosaurs, like the way God wanted it too.

Ban all the huggers!!!!!!!!!!!

Wish I really understood physics. It takes a 2000 pound battery to power the electric forklifts I drive at work for 10 hours.
