  • Compact yet spacious, safely enclosed, and efficient in every aspect-spend less time and money stuck in traffic, and more time doing things you actually want to do. The Lit Motors AEV is designed to streamline the drive, whether you're commuting to work or going on a weekend joyride.
    Our vehicle is an exciting exploration in vehicle architecture, leading a new era of sustainable transportation.
    Consider this:
    🚘 Transportation accounts for 29% of carbon emissions in the US
    👤 75% of people in the US drive alone (50% globally)
    ⚡️ The typical EV battery produces 18 TONS of CO2 over its lifecycle
    The solution? Cut the car in half, make it 6-8x more efficient, cut emissions by simplifying manufacturing and reducing battery size (and make it really, really cool! 😎)
    Our AEV is projected to produce only 1.8 tons of CO2 over its lifecycle, which is a whopping 90% reduction in emissions. Be kinder to the planet (13.2 miles / kWh) AND your wallet (only $2.50 per 170 mile charge in California - price may vary per state) 💸💸💸
    Invest in Lit Motors and our mission for sustainability: we've launched an equity crowdfunding campaign with the goal of moving into production development. Head to our Wefunder campaign to learn more! ⤵️

    FSD combined with C-V2X eliminating accidents and injuries is going to be even more important than all the other safety technologies.
    C-V2X connected cars technology is a quasi super power sensor, able to see through anything and around corners and that should be combined with FSD to end all accidents and injuries involving pedestrians, bikes, animals... It could be retrofited using cell phones or tags, or devices like the Comma ai open pilot device when adopted. The DOT needs to fast track it ASAP.

    For a two wheeled vehicle, a speed of 120 miles per hour is already too fast. For safety reasons, hub motors can be used with a speed of 95 miles per hour and 35 horsepower is sufficient. And the body can be extended by 30 centimeters, making rear passenger more comfortable; Lengthening the vehicle body and using hub motors can free up more space for installing larger batteries, as gyroscopes consume a lot of electricity every moment. (It may be a good choice to simply cancel the internal combustion engine.) The hub motor can also be easily designed to switch between FWD, RWD, and AWD modes, or the computer can automatically allocate front wheel torque to adapt to off-road roads or rainy and snowy weather.

    对于一辆两轮的车辆来说,120英里的时速已经过快了。出于安全性考虑,可以使用轮毂电机,时速95英里,35马力就足够了。并且车身可以加长30厘米,使后排乘客更舒适;车身加长并使用轮毂电机,可以腾出更多的车身空间安装更多更大的电池,毕竟陀螺仪每时每刻都需要消耗大量的电能。轮毂电机还可以轻松设计成FWD\RWD\AWD切换模式或电脑自动分配前轮扭距,以适应越野路面或雨雪天气。

      @@litmotorsofficial Well, for a small motorcycle, the gyroscope consumes a considerable amount of electrical energy.Because gyroscopes consume electrical energy every moment. Even when the vehicle comes to a stop, its RPM is still very high, which may affect the vehicle's range.

      @@litmotorsofficial A power of 90-800 watts is actually not small, and a household air conditioner used in a single room is only about 1000 watts. This is equivalent to the vehicle being driven with air conditioning on from start to finish, and the thallium gauge will also occupy the battery space and shorten the vehicle's range.

    There once was a gas powered vehicle similar to this. Instead of gyroscopes, it had two smaller wheels that would automatically deploy as the vehicle came to a stop. I think it was made in Germany. It sold for $100,000 dollars. 1:18

      But it is not even close to this concept. The one with 2 wheels deployed would fell down if hit by other car, this one wouldn't because gyros would keep it stable even if got hit. It is shown in this video.

    @Lit Motors I don't want to be nit-picky, but your gyros don't "absorb" the impact. They "compensate" for the impact. Other than that, this is a cool project. I just hope you don't get crazy with the price. This shouldn't cost more than a normal 4-wheel car with similar or better performance, like some of the other single and two seaters currently on the market.

    Didn't a 1920's steam engine do this? It was a vertical disk that counter rotated on the lean while on a single rail.
