E+ 1000W?

[turoczi]

This is funny. They raised the current in a 500W motor to appear to be a 1000W motor. I posted this on the E+ forums and it was deleted immediately.
A true 1000W motor would weigh about 35 lbs.

Any 500W motor can be a 1000W motor simply by increasing the current like BMC, E+, Golden motors. Bad business tactics if you ask me.

I just thought it was funny that people buy into this stuff.

I own TF IO cruser, restricted to 500W Canadian model.
Restriction is done through sofware by which controller is programmed.
On the top of it there is speed restriction.
So is 1000W model, some not electric/electronic people can think that there some physical changes to motor.
Not at all - output power of motor is manipulated through sofware, how?
Simply PWM chopper is "told" by microprocessor controlled by software to provide wider pulses to the motor which result in bigger power delivered to from battery to motor.
Optibike does the same thing .
What probably some people think they are getting more poweful motor, but in reality they get twiked sotware.
I like that you brought it up, it often misunderstood subject and no manufacturer want you to know that they charge hundreds for tweeking sofware for "upgraded " model.
Why there is always nothing on web sites how exactely this bigger power model is achived?
It is not exactely as you write.
It is 1500W capable motor sold in diffrent sofware configurations.

This is the approx size of a 1000W motor.



It is simply bad business tactics to flat out lie about the power of an e-bike. Just my opinion.

I have a golden motors 1000W kit and they simply shunted the speed controller to accept higher currents.

Why cant people just be honest?

Why cant people just be honest?

Because this is a new area, where terms aren't set in stone as to their definition. Do they mean it peaks at 1000w, or is it a motor that can run at 1000w continuously (and at what ambient temp are they testing), or are they claiming the average power draw is 1000w.

In my opinion at this point in e-biking, unless you are buying a pre made bike knowledge about different motors, how far they can be pushed, and a basic understanding of what is going to make the bike move is necessary.

I know my Bafang hub motor is rated at 200w I think, but I am pushing it to 35mph, and drawing 1200-1400w from it for extended periods. Really, don't pay any attention to motor ratings, because they are meaningless until there is a standard spec list you can look at for almost any motor to compare.

[miro13car]

He is talking about E+ bike/GOOGLE IT!/ ready to ride not just motor.
Company designs and manufacture 1500 capable motor/TF old specification/ which is not just connected to battery and throttle. There is controller between which decides how much power is sent to motor.
Controller is governed by software.
And just by changing parameters when sofware windows open you can change power delivered to motor.

Tostino,
you are writing about analog situation, with sotware you CANNOT "PUSH" motor,
What Turochi is talking about is that manufactures /resellers charge hundreds of dollars or thousands of dollars for tweeking sofware on identical motors and controllers.
1000w e+ BIKE IS MECHANICALLY IDENTICAL to 750W BIKE.
So what are you pay for if you choose 1000W model over 750W model?

So, BMC 400, 600 and 1000w is all same? Whats (did they) changed to make their claim of higher wattage?

[miro13car]

I don`t know about BMC, but E+ bike /old TForce bike/ uses the same physical motor with contr inside, same battery.
Bigger power is achived by means of software.
You can see on the picture that is the same physically motor.
Same with the most expensive ebike in the world - Optibike.

Again,
dicussion is about bikes no motors.
BMC or other - if you see 3 sizes of motor they are presumably 3 powers.

I allways want to know for how long? You can get 1000 watts out of any hubmotor for a few minuites. I think anything rated 1000 watts should be able to stand a 1000 watt run for one hour, minimum, in 90 F weather. Not many motors can do that, unless they weigh about 25 pounds, like the x5's. Everybody in the room who's smoked more than one motor raise thier hand.

How Wavecrest rated TF 1.5 kW motor? I have no idea.
I remember that from their literature.

But then is it 1000W output or input? At what speed? Does it have to be built into a wheel? Can the air be moving?

In the end, it doesn't matter because smart people find ways to have their products appear to do very well in the standardized tests. This testing performance doesn't always mean it'll perform better in the real world, so I don't think we're farther ahead.

E+ motor is for sure 1000W capable if sofware of controller allows for that.

[WonderProfessor]

E+ motor is for sure 1000W capable if sofware of controller allows for that.
What is unfair that company charge hundreds if not thousends for upgrade from 500W model to 1000W model
which is simple sofware re-progamming and all this laymen think they got bigger 1000W motor which is in fact the same physical motor.

IBM, Microsoft, and many other technology companies have been doing this for decades. IBM used to sell the same printer or computer or whatever as several different models. When you upgraded, some guy in a white shirt with a briefcase would show up, open the back of the device, and flip a few jumpers and voila! You now have the upgraded model (after paying the upgrade cost, of course). Microsoft sells the same software in several different versions. They are all awful -- by design. Huh? By selling you awful software, they can convince you that if you upgrade, your problems will go away. "You bought the low-end version? No problem! Here, upgrade to the next version (after paying the upgrade cost, of course)." When that system doesn't work any better, they will push to upgrade to the next buggy system (after paying the upgrade cost, of course).

All we can hope for is that the e-bike manufacturers will not learn these lessons from the technology companies.

[miro13car]

You analogy is to much streach.
I doubt there 2 identical printers out there except software loaded into them.
There use same some only components, mech. subassemblies but more expensive one in line has more added futures like extra buttons etc.

I own the 1000w bike from e+, and it peaks more then a 1000 watts according to my controller. I cant say enough how great this bike is. I zip all around the city of New York keeping up with fast traffic. ( or passing them) I get around 25 miles to a charge with pedaling, and hit 38.2 mph on the flats yesterday with pedaling. Its a fantastic e bike !

This is the approx size of a 1000W motor.

now compare in this pic the motor size on bikes #3 TidalForce/E+ & #4 crystalyte 5305.
ooopsz!!
might wanna extract foot from mouth.

Its only $300 more not thousands yea $300 is a lot just to change just software but it does allow the seller to make a small difference in price for what seems like a fair ammount in difference of power so they can earn some extra cash without having to have completely different builds of bikes....not moral mind you.

what I want to know is how much power can I put into my '1500w' motor? is it really 1500w? can I 'overclock' it? I currently have a 72v 20AH LifePO4 and a '1500W' motor I can give it 100% throttle for a fairly long time (I dont have enough road to keep it on full) but its never cut out going 100% for extended periods of time...my motor has no markings on it but it looks to be the same size as the ones posted here. it weighs roughly 10kg and is too wide for me to put disc brakes on.

[Gidebike]

that pic earlier is the same pic this website is using to show a 10KW motor!!!!!!

EnerTrac MHM602 claim they can get 60MPH from 96v 95amps on only 18" rim!

How wrong you are. The watt rating is based on continuous running at that wattage. A 500W motor can't be a 1000W motor. It's either one are the other. Just because you can run a 500W motor for a period of time at 1000W, doesn't make it a 1000W motor. I've put over 3000w (80V @ 40A) into my GM 500W motor. By your standards it would be a 3000W motor. Sorry, it just doesn't work that way. Unless a company under rates their 500W, it's windings will be of smaller gauge wire than their 1000W motor and probably some other internal differences, The weight will be just slightly more than the 500W motor because of the internal differences, but the outward appearance could, and likely is identical. Having both a 500W and 1000W GM motor I can assure you they are not the same, even though they look exactly the same from the outside. Now it's quite possible that a company selling a whole ebike could use the same 1000W motor for all their bikes and limit some to lower voltages and wattages. But don't classify motors on this. I highly doubt that E+ (if that's an ebike company) would subject themselves to a major lawsuit ny selling a 500W motor as a 1000W motor as the cost per motor difference is probably less than $5 in manufacturing.
