Anyone have acceleration times for the 3500? Specifically, 0 to 30 mph at full throttle. I'm trying to get an idea of how it would fare in stop-and-go city traffic.
Hello Jeremy,
As posted earlier in another thread;
These figures are what I got with Dynolicious.
I have no idea how accurate they really are, though some seem about right. Remember, I'm #235; as my girlfriend likes to say, I've got a big m-ass.
My 3500 arrived today, so I'll post back when I get some numbers. The instruction manual claims 0 to 55mph in 6 seconds but that seems, umm, "optimistic" since the top speed is reportedly around 40-50mph.
O to 55 mph in 6 seconds WOULD be optimistic - that would be just a little less acceleration than a current day Corvette or a modified 1960's V8 muscle-car.
Did they mean 0 to 55 kph in 6 seconds? That still is probably way optimistic.
Should the decimal point be one place further over on the acceleration G's? That would be equal to 0-60mph in 1.6 seconds.
Actually you don't need a lot of acceleration in stop and go city traffic. City traffic is the most friendly mode of riding for my e-max, even before it was modified.
Well the manual says "0 to 55mph (88km/H) takes only 6 seconds." But I think that's just wishful thinking.
I think 1.76 G's would be pretty "X-treme" indeed; maybe 0.176 G's?
The reason I'm concerned about acceleration is that I live in Boston, where people drive like maniacs. On the side streets there will be no problem. But on the faster-moving streets I want to be jumping out in front of traffic and staying in front; I don't want to force people to pass me. Passing someone Boston-style means giving them about 1" of clearance, then cutting in front of them and slamming on your brakes. Bonus points if you can knock them off the bike without actually touching them. If you think I am kidding, come visit Boston sometime :-)
PJD,
I didn't edit the Dyno figures 'cause I didn't know which were accurate and which weren't. Just posted them for what they were worth...not so much.
I pulled all my batteries tonight to replace my bad cell, so I'm pulling zero G's now :)

I have been to Boston several times and I hear you! The drivers are crazy...good luck :-)
Green electric power and use thereof; what more do we need?
I received my bike and took it for a quick spin. So I will answer my own question, basing my answer on the highly scientific instrument known as the "butt dyno," i.e. how fast did my butt feel like it was accelerating. (For the record I weigh 180lbs)
I'm going to guess 0-30 is about 10 seconds, which isn't blazing fast, but when you're sitting on a two-wheeled motorized vehicle for the first time, it is fast enough! So for now, I am quite pleased with the acceleration and I think it will be sufficient for city riding.
I'll post a more detailed review after I've, um, properly registered the bike :-)
I've never been to Boston, but from the stories I've heard, It sounds like it is similar to Caracas or Maracaibo, Venezuela, or some Indian cities.
Fortunately, I now live in western Pennsylvania, where drivers are speed limit abiding and polite to the point of it being dangerous. One must be always on the lookout for the "Pittsburgh left" where a driver will suddenly stop at an intersection to politely allow a car going the other direction to complete their left turn onto a side street.
Good brakes are needed more than acceleration. BTW, bit off topic, are there any bake squeal problems on the XM3500? I have never figured how to fix the rear drum brake squeal on my e-maxs. Any ideas Mr. Chen?

I did a quick time going to 30MPH (60KPH indicated) from a stop and it was about 6-7sec. This was on a flat and ~90% pack charge.

So that accelerating is more important than top speed in this case.....
Under the same power,it should be reasonable torque and RPM....
More power motor with higher speed and bigger torque would require for more battery and much more expensive price.

The directly drive power come from rear wheel,so that hub motor scooter have to be rear disc brake if you want to be more safety.
