And an Stark does not have any gearing. But delivers over the whole rpm band. With nearly konstant HP over the whole upper band. No need for switching gear and looking for the right rpm band. So no need to change gearing. As long as most riders dont even use the full 80HP, but chose to drive...

HP is also dictated by what the motor delivers. And by the gearing. HP is independent from the gearing of the motor. Therefore it is so useful to characterize an engine. Just one single number.

Torque is also relative to wheelspeed. On a EV the torque kurve goes down softly from its max at 0rpm. And your measured HP curve is as flat as the regulation of the electronics allow. But much flatter than in an ICE engine.

The torque curve is not flat on the stark, but the electronic turns down max HP to 80 HP, so the HP curve stays constant. You found a way to enlarge HP on a vehicle by changing the gear? Try to get a patent. That will be worth billions in the car industry.

NM is torque, J is Energy, W is power.

No, the top of the HP is always near the End of the usable rpm. At a certain point te torque curve drops faster than the rpm rises. That is the point of max HP. With the Stark the HP does not turn down, as it is downregulated from max HP by the electronics (I assume the maximum possible HP of...

Nope, you do not. The HP stays constant. HP= Torque*rpm. Simple math. you change gearing to 1/2", then you raise torque by doubling, and rpm by half. The multipilcation keeps the same. There is no way to change HP by changin the gearing. What you suggest is to double the rpm for the engine per...

No, its always torque that moves you. Horsepower is just a mathematical construct. Therefore HP is always abysmal in low rpm. By changing the gearing you always change torque, never the HP.

You might be right, in germany it is ruled by the StVZO. That is german law.

These mirrors ar able to fold back.

Its all in one package. You have to write an email to the distributor. The throttle is standard, that is just an extra protective hull around it.

The plate has a 30° angle. The mirrors can be folded back if necessary, the view is excellent. I tried them downward, but I do not like it. I have several other bikes and I am used to upside mirrors.

Here is a picture of the clutch lever and the switch with which I change the traaction control.

I have a quick release mechanism for the license plate.
