    THis cool. Can someone tell me why electric vehicles have lower top speeds then their gas counter parts?

    @Kamenwati: Torque. More specifically, the lack thereof. A bigger flywheel helps, but also offsets the lightness you need to account for the lower torque and battery weight... Also, heat dissipation in the windings of the motor is an issue

    @craighyatt: I checked this thing out a bit ago. It is rather small, tires are as thin as an early 70's moped, brakes are from the illustrious 'Tiger' company, and other than that, it seemed like a cheap Asian knock-off of a product that does not exist.

    I've been checking into electric motos for the past few years, along with electric conversions or a diesel/biodiesel/veggie-oil motor for a wonderfully light Bandit 400 chassis I have. It's getting close. I want to ride the Vectrix scooter, but it is a scooter - the thing looks well made though.

    @Lizard_King: my electic bike conversion is OK, but I long for just a tad more speed. i suppose that will always be the case. i think the top legal speed on a bicycle in my state is 20MPH, but you can get away with maybe 25. I am currently running around 20MPH if I pedal assist a lot. My controller is 36V but is rated up to 48V, so I think my next move is a higher voltage battery when this one dies. The battery I have is LiFePO so it should last a pretty long time.

    @gransee: Exactly. 150 miles is great for a motorcycle. Both my old Honda and my current Harley get a bit over 100 miles to a tank. 150 would be an improvement for me.

    @bucho54: I would not call anything less than 200 miles per tank convenient (car or motorcycle). At anywhere from 4.5 to 5 gallons, all my bikes for the last 10 years have gotten at least 200miles per tankfull.

    For an electric bike? I'm hoping for 50 mph for 50 miles per charge. That would make it convenient for my needs.

    @Lizard_King: You know what would be convinient? An electric teleporter. So i can teleport from my bed to wherever I need to go. It's convinient because now before I teleport I have to start up my deisel motor in my bedroom. It sucks because if I don't teleport in time, the carbon monoxide from the motor kills me.

    @bucho54: umm, that is 150 miles, followed by 8 hours of recharge time (at standard household current) before you can continue riding. Whereas refuel time to full "charge" on a gas powered motorcycle is less than one minute. A typical ride from san diego to san francisco, about 500 miles, takes about 8-9 hours on a gas powered motorcycle, including lunch and gas stops. On the electric bike, the same trip would take 40 hours, including 32 hours of downtime for charging. Bring a few good paperbacks and a pillow. If you can find 220v charging stations, downtime is reduced to 8 hours, making the total trip 16 hours, or twice as long as the gas powered vehicle. Nice looking bike though. And great for short rides of up to one hour away from home, after which you need to turn around and ride back to charge up overnight.

    @diablomuerte: I'm sure there would be an iPhone app that would show you the nearest 220V outlet you could poach from given any amount of popularity of vehicles such as these.

    If a Vectrix ([www.vectrix.com]) wasn't a scooter, I would think about one seriously.

    @Lizard_King: i dont see any real prob with it, my nc30 only got about 125 miles on a full tank and that was more than enough for almost any day to day travelling i do, most people wouldnt want to cover such long distances on a race position bike. not sure id be too happy with a silent bike though

    @spudhed: The comment was intended to show how this whole electric vehicle concept might not replace full gasoline vehicles' duties right away, but still be useful, as in: While I don't find internal compustion bikes convenient when they have to be refilled less than 200 miles, I would certainly use an electric bike that gets 4 times less the mileage.

    When taking trips on my bike, I've often gone 75 miles without an open gas station... I'm glad it get's high mileage and has a huge tank.

    Electric is not going to take over right away, and that is fine, I still want one.

    Someone correct me if I am wrong, but isn't carbon fiber becoming the new asbestos?

    Why did they have to fiberize it, when they should have left well wnough alone keeping it in it's inanimate rod form.

    @HumungaCowabunga_GitEmSteveDave: I believe it's carbon nano-particles and nano-tubes you should be concerned with. Carbon in itself is not dangerous, so far as we know, we use it in pencil lead. Nano-structures are considered dangerous because they're smaller than human cells and can potentially invade the cells, causing undesirable side-effects.

    Going from what I know, (as a materials engineer), carbon fiber is designed to replace sheet metal and rods. Carbon, in its natural form is too brittle for most applications, it also tends to flake, thanks to its molecular arrangement. Carbon fiber materials are typically made up of a sheet of woven carbon, as well as a light-weight epoxy that allows it to hold its shape. The resulting product has a lot of desirable properties. It's durable like a metal, it has a high yield strength, like a ceramic, and it's lightweight like a plastic.

    I look at this in the same way that I look at Windows Vista -- it is a nice piece of technology that will move us toward a truly useful product, but there is no way in hell I would ever actually buy it. That said, there are those that would think this is a quality product worth the price. Thank the gods that Vista and the Tailwind exist to warn me to not get too close to these individuals.
