Question, how much HP do the majority of the 250 mx bikes put out now? I am not talking stock of course, as on the Alta site they list the bike as putting out 40HP and with the MX map, "Power is restricted to that of an equivalent 250 4-stroke"
I thought most racers are putting out more than 40HP in the current 250f's, is that correct?
I look forward to your moto update.

Anyway, when you get more comfortable going fast you'll want to revalve the forks and shock, they're very soft stock (damping wise, not spring rate). Make sure you pull the rear subsection off (4 bolts) after any wet ride or washing as mine fills with water. Just tilt if forward and the water finds its way out. Just a quirk of the "composite" construction. I need to figure out where to drill some more vent holes but you'd think Alta would have fixed this already (note, there are a couple of holes but they don't seem to work very well). There's a few other quirky things but you'll figure it out soon.
Good luck, we Alta owners need to stick together as there aren't many of us out there right now!
And what is charging time? My usual practice track we run 20 minute sessions and then you're off for 40 mins while beginners and minis get their turn. You can put a couple of hours on the bike, sounds like the battery is good for a out 1hr for MX use. How would this work, short of bringing a 2nd bike?
I am anxiously awaiting the day I can buy one (still out of my price range at the moment), but I love hearing good news about them. Keep up the reviews as you ride it more.
Which brings me to one of the unique characteristics of the bike, no transmission! With the Alta, the more you turn the throttle the faster the engine spins (translated, the more torque is applied) and the faster you go. Simple as that. So throttle position controls both torque AND speed. On a conventional bike with a transmission (electric or gas) you have a means to decouple speed from torque.
For example you mentioned jumps. My riding preference is to use speed and not torque to clear them. I'd typically accelerate up to the jump (high torque) and then shift up to lower my torque but keep my speed. I just feel more in control that way. With the Alta I can't do this. I'm kinda stuck with whatever torque the motor needs to maintain the necessary speed, even if it's way more (or less) than I want. This is not to be confused with engine/motor braking, which Alta has managed to replicate quite will.
The lack of a transmission eliminates one control variable at the riders disposal. In general I feel the advantage of not having to manage this tool outweighs the disadvantages, I just need to re-learn a few old riding habits.
In regards to charging time, with a 220 volt generator I can pretty much top off the battery from practice in about 30 minutes. Between motos about 1 hour from 25% to full charge. Frankly, you probably don't want to race below 20% battery anyway as voltage sag will reduce performance.
Also I think the Honda and Suzuki are still under 40?
Mark911, we also are reading, and really appreciate, the critiques. On the charger case, drop a note to info@altamotors.co or talk to the dealer where you bought it and we can set you up. Those weren't yet available when the rest of the bike was and we weren't about to hold up shipments over the box the parts come in, but we can get one to you now. The rest of the feedback goes straight to our R&D team. Keep it coming, whether here or directly to us at that same email address.
Great write up Ben990.
I can see so many more opportunities to throw a leg over a bike without pissing people off with noise. So looking forward to the future of dirt bike riding.
No Alta bikes here, but these guys rent out electro bikes to ride on their indoor & outdoor "tracks". (in Netherlands)
I'll probly go there somewhere this summer, as i'd really love to try a electric bike in general!
I wonder when KTM will have a "real" race electric bike, i'm sure that they have plans for one.
I liked reading all of the comments, and here are my replies:
I too was skeptical of electric bikes, but this thing has removed all skepticism. Several years ago, I had a Zero Motorcycle rep bring out a demo bike, and a bunch of us rode it. I think it had a price tag of about 9K, While fun, it was not competitive, and seemed more like a motorized downhill mountain bike. This thing is not only on par with modern mx bikes, but better in a lot of ways. This bike has also opened up so many riding opportunities for me, and I can now ride out of the garage ANYTIME!
I paid $14,995 plus $475 for freight/shipping charge OTD, but as I mentioned in my original post, I also got 2 t-shirts and bike numbers! I know, pricey, but I think over time, the cost of ownership will line up with that of a 250/450. There is a one year warranty on the bike, except for the normal wear stuff, like brakes, chain and sprockets, grips, ...
The charge time from 0 to full is about 2.5 hours. At the track, I will use either my motorhome generator or a portable generator to charge the bike between motos.
There are 4 maps accessible through the computer on the handlebars. Map 1 is a tight trail mode map, and is soft. Map 2 is restricted to the performance of a 250F. Map 3 is an aggressive map, and map 4 is an over-clocked map. I have experimented a little with all 4, and I think I prefer map 3. Map 4 uses up the battery the quickest, and I think I read someplace that someone went for 5 hours on map 1. What is cool is that you can switch maps on the fly; you could start a race using map 4, and then switch to a different map later on, using the up or down arrows on the left side of the handlebars. It also gives your left hand (clutch side) something to do!
mark911, feel free to thank me when you get your case!
As far as jumping this thing, I was able to get used to it pretty quickly. If you come up short, you feel the weight of the machine, but then again, I am 6' 1" tall and weigh 215 pounds, so most bikes I ride need heavier springs anyways.
The Alta suits my riding style; I am a vet intermediate, and I raced KX500's for years, and my current race bike is a 2016 Yamaha YZ450F. On the 500's and the YZ450, I start in 2nd, and then shift to 3rd, and usually navigate the whole track in 3rd. On the Alta, I start in, well, uh, um, I guess I push the engine button and just go! The thing never bogs, and the amount of power available feels perfect whatever opening the throttle is at. I feel like my cornering is faster and smoother. It almost reminds me of coming out of a corner on my KX500 in 3rd; you roll the throttle on from a low RPM and it accelerates super hard and you rocket out of the corner, but unlike the KX500, it is ultra-smooth and you don't have to back off because it gets violent. Jump for show, and corner for dough, right? This thing will make you corner better.
The only short-term changes/upgrades I plan for this bike are some suspension tweaking (first play with compression/rebound settings, and then maybe heavier springs if needed) and I want to either sharpen the stock foot pegs or replace them with aftermarket pegs, as the stock ones aren't very aggressive. I believe modern Yamaha foot pegs will slip right on.
I did hear that KTM is coming out with an electric version of their Freeride trail bike, and that the price tag was going to be around $16K.
fasterfaster (Marc, CEO of Alta), it is great that you check out this message board. Feel free to send me an Alta sticker and I will include you on my list of sponsors!
Here is my planned Alta ride schedule for the week:
Practice moto Tuesday (today) - my personal track
Practice moto Wednesday- my personal track
Practice moto Thursday - friend's track
Practice moto Friday- my personal track
Motocross race Sunday - Pavilion, NY
Just because I can!!!
And, I always tell people the extra $6k it costs to buy the bike is the attorney fees you won't have to pay to fight townships to ride on your own property.
Can't wait to get one.

I am not a buyer for now, but this thing is absolutely on the radar. I realize that most talk about bringing the cost down, but as a Vet intermediate myself I feel like if your gonna be a bear, be a grizzly. I would love to see the Cone Valve fork option with spring choices for special order with a left hand rear brake. Custom built to order. I know it seems like a lot of money, but have you priced a Harley lately? It's just another $100 a month or so...
Love the lack of real track prep and the ability to just GO! Motocross can feel like such a Show sometime, with so many moving parts - you need to love it to stay committed to the responsibility.
Thanks for sharing, and really impressed by Alta's CEO doing what all companies should be doing, using customers to develop their product.
I would recommend calling them to see what they are up to. The group of guys there are core and super nice. They don't appear to be in production of anything yet but perhaps they may send you something to test and you can have another "Sponsor". I have no inside info on whether or not they actually do this type of thing but given the limited number of these bikes out there in the real world maybe they would?

Left hand rear brake
Springs to rider's specs
I have to hold off until the endurance can for sure complete a 2 hare scrambles or GNCC length race... I'll wait and I'm hoping it won't be too long...
The thought of no more oil changes and air filter cleanings ever again sounds like heaven.
The only issue is having to drag a generator around with me. I don't do the overnight camping thing when racing hare scrambles so I don't have access to a generator and I'm not putting a gas fume emitting generator inside my Tesla Model X P100D. I carry my current bike on a moto rack (no trailer). This really creates a dilemma for me. I really want one.
Gotta see if it can do a full 2hr hare scramble at Vet A rider speed.

When you "rev" the alta in the air, wouldnt the gyro effect be huge and make you do like a "half" backflip? I mean it would be like if you shifted up to 5th in the air and held it wide open
Of course this could also be a huge advantage if you hit a kicker and it throws you forward in the air
How can I invest in Alta Motors?
