There are two WiFi/BlueTooth modules. One is in the VCU (vehicle control unit). The other is in the "dock" which is right beneath the phone. It talks to the VCU via CANbus and the phone via BlueTooth (charges phone via Qi -- notice the red LED on the phone). You can choose to use your phone as...

Oh, and one more thing. We've been told "write the firmware so that the bike can work just fine without the phone". I don't know what decisions are (or will) be taken with regards to premium subscriptions and such things. What I do know is that on a technical level there is no real dependence...

The android app talks via bluetooth -- in initial testing that ended up working better than WiFi. There is also an "engineering interface" that we developed independent of the app where we use WiFi and it is web based. It is HTML5 + WebSockets (bike has a little web-server running in the VCU)...

Very insightful comment wrt testing and improvements.

Anton will give the specific details when he sees fit. For now I will just say this. Remember how there was talk that the media event bikes are hand built using special materials/components and that the production bikes would not be up to that level. Not only is that not true, but the opposite...

If I were in your position I would gladly take the delay. I know certain things ;)

There is a context to what Tortelli said. So far there has been one produced bike intended to take on combustion bikes -- Alta with target of 250F. Now we are approaching production of the Varg -- target of 450F. Both these companies didn't/don't produce combustion bikes. The freeride doesn't...

The software is indeed challenging. It is challenging in ways that an electric car is not. Let's just take traction control as an example. You cannot use speed of the non-driven wheel. You want to avoid if/then/else paths in the code because they correspond to a step change in behavior...

The plan is for the bike to have three buttons on the left side. start/stop, map-up, map-down. On the right side we have only the throttle. Any idea how to engage reverse?

At first I saw that as 5' instead of of 5". There was a piece of junk on the screen. Reminded me of the Spinal Tap Stonehenge scene, but reversed. Sure you don't want 5 feet instead - would be a lot more spectacular.

In addition of putting on a large media event a bunch of other things need to be done. The factory needs to start running. This is not isolated from the development engineers. The behavior of the bike is in large part dependent on the software -- a lot of work remains especially with regard to...

The charger is rated 3.3kW _output_ power. I would expect low 90s efficiency so it works out to about 16A input which is the current rating for the common european plug.

The software is behind the hardware (because in this case you need the hardware to write the software). To really push the bike -- especially with the media riding it -- the software needs to be more mature. The last thing you want to do is change the software from day to day while the press are...

It is considerably more powerful than the Alta. A number of riders have ridden both bikes. If it was less than the Alta the media would rip it to shreds.

There is a fan. It is an actual radiator fan designed to be exposed to the elements -- not some computer fan. The electronics measures fan current draw and warns you if there is some problem with the fan. During charging the coolant pump and fan is controlled to bring the coolant temperature and...

First, let me state this. Alta is the first legit electric dirt bike. Second, the "IP" that BRP acquired is just about completely without value. This is not because Harley holds some blocking methods by which they can screw BRP. Where are the design and R&D engineers? The pieces of paper and...

They are not stupid questions. I do not have an Alta so I cannot check. Perhaps the bike spits data out on CAN regardless if multitool is connected or not. If somebody connects a CAN dongle to it and there is a bunch of traffic on the bus then the bike is probably spitting out the data and...

I have played around with a non-rooted phone running Termux. I got it to use a USB serial device (normally /dev/ttyACM0) under linux, but it didn't show up as such device. I hade to use libusb to get it to work. Also, it doesn't work on every phone. IMO, that route is painful. It is much easier...

Is there some sort of published protocol or does it need to be reverse engineered? It would be much easier to just pipe CAN to WiFi or bluetooth and do the processing on the phone.
