    Just came across this interesting piece of news on Yahoo India.

    - Described as a "motorbike-car" hybrid, the Lit C-1 two wheeler uses a set of futuristic electronic gyroscopes to ensure it remains upright and balanced, similar to the technology used by Segway scooters and the recent Honda UNI-CUB.

    - A group of scientists have announced that within a few years it may be possible to sell a two-wheeled vehicle that can't tip over.

    - The technology allows drivers to sit and use a steering wheel, as in a car, but allows the C-1 to stay perfectly balanced, even at slow speeds or a standstill.

    - The secret to the balance are the gyroscopes under the floor, which spin rapidly in response to electronic sensors to keep the vehicle balanced at all times -- even, says Lit, if the vehicle is involved in a collision.

    - Gyroscopes, which harness the unique propensity of a spinning flywheel to stay upright, have been used for some time for stabilization, including on aircraft and on cruise ships to reduce roll caused by waves.

    - The model can even cope with some luggage and an extra passenger, says Lit, although it's likely to involve some considerable acrobatics from the rear passenger given the small size of the device.

    - However, this will be one of the most unique applications to date, potentially enabling drivers to switch to smaller vehicles which offer the benefits of a bike with the comparative safety of a car.

    - The manufacturer says that it could be available in showrooms by the end of 2014 -- it's already offering preorders on the website from $250, although the final price of the vehicle is unclear.

    - The C-1 uses electric drive and offers a battery pack capable of 200 miles (321 km/h) from a single charge, as well as reaching a top speed of over 120 mph (193 km/h) -- far faster than most electric cars available on the market today.

    That is very interesting. The basic science involved is the good old one. Dynamic stability. The same one which make the bike stable at high speed(with spinning of wheels).
    It looks like the gyroscope may be also adjusting with the speed of the vehicle, with lot of sensors, when the spin of wheels may not be able to give enough dynamic stability. For example in the case of a sudden braking it can sense it and activate the gyro to adjust accordingly. Great move. But in india we may not be able even dream these things.
    May be our kids will be going to college in these bikes:D

    i remember having seen it in one of the episodes of topgear with jeremy clarke testing it. it was really unique to see it drive on curves. the thing different in this was that the whole body bends with the front wheel while taking a curve but the rear wheel remains straight! one needs to see it to understand!!

    Sham, What I guess is that they may be using one gyro for rear wheel for stability. Since the rear is stable because of spinning wheel the may be using spring force(or any elastic force to bring the front part to equilibrium position. So they don't have to worry about stabilize both the wheels using gyro and all with lesser energy consumption(rotation of gyro). Just a possible guess need to understand more.

    An interesting video is here.
