Your understanding is not correct. Parts of what you say are correct, but certain bits are just wrong and lead you to the wrong conclusions. First, the battery certainly does care which axis the current is going to. Second, thinking of the Q axis as the torque axis and the D axis as the...

There is a decimal point. The video was taken a while ago and I just happened to have it on my phone. I didn't do a dyno run for this exchange. At that point (and still at today) the power curve is not perfectly flat. There is an 8% drop from max power to high RPM region. That can be tuned flat...

Hi guys. I don't mean disrespect for Mark, but if you look back at his posts he's been pretty negative about the Varg. I would consider it borderline spreading FUD about the bike with statements like "So, it's easy for me to see something like a Varg making an 80hp dyno spike for advertising...

This is not some motor from company X connected to company Y's inverter that has no idea how to effectively flux weaken the motor at higher RPM. You can count on one hand the people who designed the motor, designed the inverter, and wrote the vector control software. At work they all sit within...

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...
