... electric bikes?? I heard that on some of the new electric bikes in development, some top riders were able to achieve faster lap times than on their race bikes.. lighter, more torque, smoother power. What would it take for AMA to allow electic bikes to compete with the current combustion engines?

Lighter? No way in hell. Not yet.
The AMA needs to determine a HP number for each class and convert it to watts.

Theres still plenty of two stroke rippers out there!...they have only been replaced in pro sx/mx...unless you're stankdog

The day AMA allows electric bikes i will stop watching the pros. I dont see combustion engines being replaced soon, unless one of the big five build an electric bike.

If they could be developed, produced and sold at a lower price point than the current bikes then sure, maybe at some point. But there is nothing wrong with the internal combustion engine, especially in our sport, so I don't support the notion to "build it because we can".

An electric motor bike could be a lot of fun but being stripped of a mechanical transmission and clutch sure does kill part of the soul and challenge of our sport.

I think electric bikes will get a transmission when they get popular. Probably just a 2 or 3 speed, but still.
A clutch could be useful too, but I doubt those will stay.

KTM makes the freeride-e in europe. It's definitely coming. The alta is f*cking mind blowing in my opinion. It's a real dirtbike with a worthy suspension and 250 class speed.

Check out the Zero TT, race from the Isle of Man TT, those bikes are quick.

Actually the four stroke took over from the two stroke who took over from the four stroke!

Why would they need a clutch and transmission?

a lot of things can be prevented if enough people make a stink about it. zero tolerance for electric in my book.

Yeah electric bikes suck. I mean, imagine not having to deal with neighbors complaining about noise, imagine more places to ride because less tracks would be shut down, yeah electric bikes are shit.

While it would take away some of the atmosphere of the races, I feel there are more positives than negatives although I also believe it will be a while before the transition happens

Don't worry boys. From my understanding, the switch to 4 strokes was based upon the ability to make more revenue from additional parts sales (not a stamped fact, but speculation and economics suggest it's so), so a switch to electric bikes I would bet would reduce the potential revenue income from said parts sales to even lower levels than what two strokes would provide.

I've ridden them before and as soon as a reputable manufacturer produces one I'm buying. Can't wait to buy one and build a SX style track on 1-2 acres so I can ride in my back yard.

"I'll quit the sport before I ride an electric bike", Hahaha, don't let the doorknob hit you in the ass on the way out!

Must be a generational thing. Guys who grew up rebuilding engines on their own bikes and cars came to love the soul of the internal combustion engine. It's feel, sound, and smell become part of you.

If you grew up in the four stroke era, you couldn't fix your own bike. Or even your own car, because everything's electronic. So you played video games and paid someone to fix your stuff. Because of this, this generation missed out on a huge part of what at one time made up this great sport. Fathers and sons working on bikes together. Kids being able to cobble together a bike to bomb around on with their friends. All together, it makes up a much less tangible connection to the sport.

Slipdog, usually agree with your posts. But not this time. I'll gladly let the door hit me in the ass as I ride away on a real motorcycle.

If having electric bikes in pro racing means Lurch no longer has to do that God awful scream at the start of each race, I'm in.

Imagine that, an old guy stereotyping a younger generation.

Shit no $500 top ends to replace or stupid oil to change or filters to clean!?! I'm all for it! Plus can just pop in some headphones jam out and ride. Sounds like a winner to me.

Transmission would give you more torque (1st gear) extended range (top gear) and a higher top speed (top gear)
A clutch would be pretty useless, but you could use it to rev the motor and dump the clutch. Could also be used a sort of slipper clutch assuming they don't just install them to begin with

Are you on drugs? Basically the world is gonna come to a screeching halt. " It must be a Generation thing". I guess everything mechanical is going to fail. Trains will quit running, refineries will stop making fuel, and vehicles will not be fixed or maintained. That was a dick head comment. I'm pretty sure mechanically buddy I'll turn circles around you.

Whoa easy there BobPA. Don't forget, riders and racers before us have paved the way for us (owning, operating tracks, trails, clubs, RAISING new riders, owning and running THIS forum) Your words are not too kind. Obviously you are a hard worker and don't fit into his stereotype. You are an exception. No need to be a jerk. His comments weren't directed specifically towards you.

I certainly agree with Hellion, there is something about the sound and feel of a combustion engine (both 2 and 4 stroke) it's a huge part of riding experience.

Electric is coming and will be much higher performance as the tech matures even further. Now watch this tesla smoke an alpha romeo while towing a 4000 pound alpha romeo at the same time!!!! https://www.youtube.com/watch?v=ib-02b2ooLY

Yes, the big 5 are all about making money and if any of them made an electric race bike I don't think it would replace their product line, more likely just be another option.

Electrics in MX will probably be a significant performance step forward. An electric bike just a few years ago set the fifth quickest time in the Pikes Peak hill climb of all vehicles and smoked the closest ICE bike. I don't think battery run time will be a great concern with the short proMX lengths and even shorter SX races. Battery run times they currently have may already be adequate for SX.

When will the AMA recognize them? Likely never unless The "Island of Japan" manufacturers want it. Mugen's won the last three Isle of Man TT Zero races so maybe the Big four will get involved. I find it really curious that Honda doesn't already have electric bikes since their corporate doctrine is that they are a "green company". That's how they sold the change to only manufacture four stroke engines after all.

It'll be expensive but I don't see too much evidence that the "sport" takes too much consideration into the financial burden of small teams and privateer efforts. As long as factory backed efforts are "floating the boat" then I think they'll implement whatever rules "they" want.

But maybe Alta, Victory, Zero and KTM and other current producers can create their own series (does Elon Musk ride motorcycles?). The endurocross series seemed to advance without the AMA for a few years.

I'd think electric MX bikes at a reasonable price could really "capture" a lot of new riders since they make possible "low noise" tracks located in urban areas.

You got a lot of name calling, straw man arguments, and anger from this seemingly respectful and well reasoned post.

But not well reasoned counter arguments.

I'll add one thing to this debate: electric bikes potentially have a lot of advantages, but currently they should not be considered 'green'. The bulk of the electric power used to recharge electric vehicles in the US are from coal burning plants and that is a fossil fuel just like oil.

Don't jump to the conclusion that I am expressing an opinion on the 'green' initiatives one way or the other, just clarifying that point.
