Wow, a little scary on what could have happened. I am guessing you ride a little harder than most people, but still you wouldn’t expect this to happen. Alta’s have a lot of torque especially in map 4 so maybe it’s just a matter of time for this to happen on other bikes. That groove looks...

That’s a great idea - might suggest some industrial Velcro with adhesive backing to attach to the side plate. If you get the right stuff it’s really hard to pull apart.

Brent421 convinced me that Ohlins is the ultimate solution. I actually was able to compare the Ohlins fork with WP AER and rear MXR shock that were revalved by KTM world (Philips old set up). The revalved WP forks are much better than stock but really don’t compare the the Ohlins. I can’t...

Hey, can you post a link to where you got the 14T sprocket from. Also assuming will need a longer chain if it’s already on the short side. thanks

Maybe time for Ohlins

That is very well done. Sort of like the Alta gearing arrangement but much more compact. it would be awesome to have a universal version where the final bolt points could be drilled for different frames. what are you thinking it will sell for.

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?
