I think electric motocross bikes should be allowed to race in the 450 class without any restrictions - think open class like the 2 stroke 500’s. The concept is an electric bike can be made more powerful than a gas bike but that is at the expense of range. Right now I doubt an Alta could have...

About trail riding in map 4, initially I would trail ride in map 2 but over time I began to like having that instant power in map 4 to skim through whooped trails and get over obstacles. Unfortunately map 4 got me real bad, was on some trails with standing water puddles, was sort of pounding...

You know Mark it’s not that crazy to get in front of the FIM. Maybe the Alta owners could bring forward information on practical use of Ebike in competition settings. There is not a larger knowledge base of users of Ebike technology in the world. Maybe a door could be opened somehow with FIM...

That’s pretty cool - must have taken hours to get that done - what product did you use

I though it would be efficient to have external pockets where you could place dry ice pellets - very small 1” squares that you could drop in - space them so you don’t over cool an area - you would have to have a type of material that could resist the extreme cold at those spots probably material...

Agreed - those in the know should know

Here is my Rick Johnson 1986 tribute motoped with era gear.

I just push in an automotive plastic plug - that connection point snaps in to the point a bolt probably isn’t necessary

The bike is posted on ebay, not a bad price at $5,500 72V 3000 Watts Electric Off-Road Motocross Motorcycle Dirt Bike For Adults 60MPH 636643399869 | eBay

Yes the motor is a QS 205 V3 with high speed windings. It’s currently set up with a 72 volt x 42 amp/hr battery and 300 amp BMS. Controller is Sabvoton sine wave 150 amp so 11,000 watts - it’s fun power but not too much. The motoped frame is pretty neat, very strong chromoly steel so it can take...

I still have the Phasor frame. It is chromoly and appears to have survived to the point I think it can be used. One day considering rebuilding. Fortunately the company I purchased the battery and power system from did a warrantee replacement and this is what I ended up with today.

That is a good explanation, I understood the electrolysis part but didn’t understand the rest. Like you said improvement in range without increasing weight would be a big improvement. i would think the electrolysis components would be more likely to need replacement and may not be as robust...

That’s some wild riding. To be honest I have no idea how people do freestyle without daily hospital trips. I am an 80’s kid and we thought one handers in the air was pretty awesome, we couldn’t imagine doing stuff like you are doing. If I were 30 years younger might be able to give it a try...

The web site has a white paper and explanation. I do not fully understand but I think it uses some form of electrolysis to get hydrogen out of water and from there I don’t get it. I watched the video of it making power?

This concept is really interesting. Teznic has working prototypes of real time on demand hydrogen generation. The concept is you have a tank of water and the system converts it to hydrogen on demand. Apparently 2/3 weight of a battery for same power and much much greater range. If this actually...

I had a very scary battery fire in 2018. You can see the amount of fire damage in the pictures. The flames were 7-8 feet tall and lasted about 7-8 minutes. Luckily I was on a concrete road at the time and was able to drop the bike and let it burn. I was riding in the woods a few minutes earlier...

I installed the same acerbis rotor guard. My solution was to turn down the diameter of the stock Alta wheel spacer and then hammer on the KTM rotor mount (friction fit). it’s been 600-700 miles and no issues yet

I totally agree about the side number plates, the shape is OK but a little weird but the ergonomic problem is they bulge out way to much so sometimes when you get back on the seat you run into them it would be great the have the modified design bolt up to the same mounting points as the stick...

I think to some viewers it is likely hard to see the design details because of the black mat finish of the 3D printed prototype when you zoom in and envision them in white plastic it will improve ergonomics in a major way and IMO improve the aesthetics as well not sure what a set will have to...

I think the design is huge improvement for slimming the bike and no knee pain. I would definitely sign up for purchasing two sets
