    I normally don't stoop to the level of personal attacks. But in your case I will make an exception. First. Your inability to read between the lines and take a hint is astounding. You would be much more at home on VitalMX. Second, the Varg is a ground up bike including motor, all electronics...

    Question about Stark charger 240v adapter: is neutral required?

    First question, yes. Correct. Second question. It will work on 110V and draw about 15A, so power draw just above 1.6kW.

    To all those bitching about the lateness... It is a software controlled machine. The software is late. If people are happy with how it performs now just imagine once the software gains features and approaches maturity ;)

    Question about Stark charger 240v adapter: is neutral required?

    There is only one charger. For 3.3kW the charger wants 220 - 240V range. It does not care if you are in Europe and have 230V with respect to neutral and earth or in the USA and have 240V center tapped. All it wants is 220 - 230VAC. Remember, in Europe there is no hot and neutral. When you push...

    Because I don't ride single track. And I am not marketing and am not in a position to organize such a video. I am drive system engineering. What I can do is show you the math compared with an Alta so that someone on this forum who rides an Alta single track can give you a range estimate and then...

    If the weight is a deal breaker then fine, I can understand that. However, the new battery pack gives you more range even with the extra 8kg. The 118kg Varg with the new battery pack will go _further_ in every use case than the "advertised 110kg Varg" with the old battery pack. If you look at...

    When we put it on the scale it was 118kg, so 260lbs. So pretty much identical to a MXR. So the weight is a significant miss. However, the battery pack is _much_ better than the original one promised. The difference is much more than the 6.0 to 6.5kwh implies.

    For MX you don't really feel the weight because the lower rotational inertia more than makes up for the extra mass. For your use case the extra weight might be an issue. Then again it might not be -- because it is distributed a bit differently than with an ICE bike. I think it is not possible to...

    Owner's Review Stark Varg - First Customer Review!

    I didn't say the Varg has some different/superior/magical vector control scheme. What I said is that current into the D axis does not only weaken the flux in the air gap. It also generates torque and therefore power. Current into the D axis is not wasted. Here, have a look at the torque and...

    Owner's Review Stark Varg - First Customer Review!

    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...

    Owner's Review Stark Varg - First Customer Review!

    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...

    Owner's Review Stark Varg - First Customer Review!

    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...

    Owner's Review Stark Varg - First Customer Review!

    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...

    Newbie need advice on a generator

    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.

    Newbie need advice on a generator

    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.

    Stark's Battery pic

    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...

    Stark's Battery pic

    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".

    Stark's Battery pic

    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...
