Our content producer had a chance to head down to the Bay Area, where we are doing lots of testing at our R&D facilities. Here's a short clip of Kurt Risic, Director of Vehicle Integration & Testing, confirming firmware settings and prove out stability with throttle control at 7,500 rpm (less than half of what's possible). Full rpm is 18,000!
Kurt brings to Damon a breadth of experience from his time at Honda, Wrightspeed, Jabil, Enphase Energy, and much more - and he is one badass rider!
Check out the video on YouTube:

Sounds almost as loud as like 250 horses all running inside that one room.
Loud pipes save lives
Loud bikes fulfill lives
Oh and they pass other bikes too.

What is to be expected to be the peak horsepower rpm? These battery vehicles seem to make pretty much max torque up until max hp is reached and then hp stays constant (or close to constant) as rpm goes up and torque goes down. Or am I basically incorrect?
I thought a normal dyno run starts at max rpm and then they load it to pull down the revs and create a graph.

Electric motors aren't like gas engines. They make their highest torque at 0 RPMs and their highest speed at their max RPMs.
You can feel it when you get to your bikes higher end it doesn't pull as hard as it does from say 30MPH to 60 MPH.
Gas engines have a power band and where they make their most power differs based on their setup.

Totally depends on the bike. My Energica happily wheelies when going 130kph and pulls like a donkey all the way up to 200kph. If the bike's motor maxes out at top speed you're right but if it is limited only on top end it goes until the software tells it to stop ;)

Hi Fran K! That is correct! The motor makes constant torque (200Nm) to 7,300rpm and then makes constant power (200hp) until 18,000rpm. The dyno is a programmable load - we use it for far more than the traditional ICE bike peak power/torque runs.
