I'm not so sure about that and I don't understand why they make those bikes sturdier. We have two problems: • strength: I think that strength is given mainly by the tensile strength and by a low enough density that allows the manufacturer to use more volume of metal keeping the weight within...

Yes, that sounds like the biggest problem. They said the chain derailed only once but they tested it for a short time, too. They said that the suspenions are a huge problem and you can see that slow-mo where both the fork and the rear shock bottom out. Maybe if the shock were tuned stiffer, then...

Here is a motocross test: @Kurlon: Ultra Bee alternative for your use?

If you skim through this video you will notice that these KXE suspensions, apparently OEM on Surrons, have a pretty weird design: it seems that there is no bushing on the stenchion, like at 5:20. And in this video at 6:18 they explain that generally in these cheaper forks there are no bushings...

I'm not saying that this is a typical example of the reliability of an Ultra Bee, maybe it's just a very rare case, but I think you can should read this thread, if you haven't already.

Hi and welcome. Ther is already a thread about this: Advance modes for MX1.0 and, as you can read in the latest posts from December, Stark said that they intended to release the update within January.

So, have they first created superintelligence and then asked it to design a functional solid state battery? All this sounds too good to be true, to me. Thanks for this, now I have adjusted my expectations. And welcome to this forum. In theory, the Verge bikes equipped with solid state batteries...

A more extended video: Something I've found pretty interesting: • The inverter and the VCU are airtight and assembled at sea level (so with a lower external pressure they tend to expand) but their engineer connected to the bike to make sure they were allright. • At 13:40 and 17:54 he deflated...

Che sorpresa! :) When you lower the bike, you lower the center of gravity, but you also lower the handlebars or whatever you use to lift the bike. Since the distance of the handlebars to the ground is greater than the distance of the COG to the ground, though, you will still make it easier to...

You may also wait some months and see whether Donut Lab really has solid state batteries. In that case, maybe some months from now it will be possible to use them instead of the more traditional ones with liquid electrolyte.

When he mentions torque, he doesn't explain that the 1,000 Nm of the Varg are at the rear wheel and that torque can be changed by changing sporckets or gear ratios.

Personally I, as a slow MX rider, think that the throttle reponse of the Varg set at 60 HP makes it little controllable when exiting from tight corners. Before the Varg I used a YZ250 whose power delivery felt less linear with a turbo-like effect at a certain point (I think when the powervalve...

Surely nowadays we as consumers can be informed easily, but the problem is that I personally believe -and it sounds objectively reasonable to me- that a helmet should be tried, so I don't buy them online and this makes things more difficult. At least in Italy helmets can be sold even if years...

"Insulator" is a relative word, since, beyond a certain voltage, basically everything becomes a conductor, even air if the voltage exceeds 3kV/mm, and then you get an arc (like it could happen in an inverter with too close cables, for example) or a lightning in the sky. The same concept holds...

In order to contribute to our mathematical theoretical dream :LOL:, I've investigated to find out the battery voltage for the 902: I've found it for the 4.3 kWh, 46 kW light weight battery, @5:06 in the video in Philip's post #1: 90V nominal. I've noticed that usually the cells used in electric...

Well, assuming that they use a permanent magnet AC motor like the Varg, the question IMO is whether its highest efficiency rpm range matches what the rider uses. As far as I've understood, neither a massively overpowered, nor a barely enough powered motor is ideal; the ideal one is overpowered...

Ok, I've ordered the Tusk press, on Ebay. The problem with RMATVMC for me is that the shipping cost was way too much. Just like they show here. I've also found out that the handles are supposed to always be over the top race regardless of the race that you are replacing; you just change the...

That's the point I think: this time the vehicle that uses the revolutionary battery exists, you can order it and the delivery is expected to happen some months from now.

Up to the moment I read @Matt's comments, I didn't even know that supercapacitors existed: I knew about capacitors and batteries and I knew that capacitors have a far higher power density while batteries have a way higher energy density. From what I've quickly read this evening (it's night here...

Pressing the race surely sounds like the proper way. However, the Motion Pro part no° 08-0669 doesn't have a compatible driver and other alternatives are expensive and rare, except maybe the Tusk. I think the Tusk press you are talking about is this. I've read the questions and the reviews on...
