So the Alta talks to the charger via CAN? 250K rate? Anyone here know the CAN IDs? If I have this info I can tell you if it will work or not.

The cable from the charger to the bike is not the same as for an Alta. AFAIK, the charger is included with the Varg so why would you want to hook your Alta charger up to it? The charger can deliver up to 440VDC if you ask for it, but we don't go that high.

Correct, moving those things to the front means the battery is a bit less tall which increases the ground clearance.

The physical space for the VCU (vehicle control unit) is very tight. We might have been able to put an output for a headlight but that is about it. So, no blinkers, tail light, etc. However, there are 4 spare pins. Two for +12V, NEG/Chassis. Two for communication. That can then connect to a LCM...

There is no spare output from the VCU (vehicle control unit) to drive a LED headlight. However, the DC - DC can put out enough current to drive a LED headlight in addition to the coolant pump, cooling fan, etc. So in theory it is possible to "rig something up".

Bodie_Z was pretty much right on with his reply. I will just expand a little bit because the architecture is a bit different than the Alta. There are two connectors on the battery. The orange connector supplies ~360V to the bike when the two main contactors are closed. The smaller black round...

Do you know the protocol or have the source code for the display?

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.
