When you see a commercial for a new car and they claim the new (such and such) now has 260 horsepower, isnt that just an achieved maximum rating?]
They do, but you have such a massive excess of power in any gas car that it's almost impossible to hit peak power continuously! you are provided a minimum of 2 times the power you need to cruise along even in the putziest of cars.. up to about 100 times the power you could ever possibly use in the most powerful car..
You also have a cooling system in your car that can deal with a massive amount of heat. You also have the engine designed to run at a top RPM that will ensure it lasts hundreds of thousands of miles. These production cars are quite detuned from the factory.
Cars have massive overhead. To the point where you can never expect to hit the limits unless you're racing and your minimum RPM is 5000+, lol.
I have basically climbed up the rockies ( a few mountains over from pike's peak ), up to 11,000ft down to sea level with 300-500lbs of my crap in the car multiple times, in a 1994 2.0L Nissan with 230,000 miles on it, and the temp gauge never rose above the middle point, lol.
All other production electric bikes have tons of overhead built in as well. My MAC motor is rated at 500w.. i think the HS/HT is rated at something like 1000w-1500w tops. And builders will typically underrate them to prevent the motor from blowing. Why? they don't want warranty returns. They also don't want a dissatisfied customer. They also want to set expectations properly before the sale to prevent other problems.
The problem with HPC is that you don't get told that extended use at 4000-5000w will kill your motor in a very short period of time. You get handed a controller and battery combo that can do the motor's peak power ( for minutes ) continuously. I as a hobbyist know that i am taking my chances and riding the line of reliability if i were to build something like that. As an end consumer, i have no effing idea.
Would you sell something like that with a straight face? at a massively high price? HPC did the same thing with the BMC motors... history repeats itself.
Sounds like HPC is interested in correcting some of their deceptive marketing, but they're not out of the woods yet.
