I've ridden motorcycles for the better part of 36 years of my 41 year life. So when I saw decent RC bikes, I just had to have one. I've had two of the now defunct, Venom / Atomik 450 bikes. One had the mechanical gyro, one had the electric gyro setup. There is no comparison at all. The electric gyro can and will go around a track, the mechanical I never could slow enough without tipping over. The electric I can drive at a walking pace and be in full control. That being said, they are a bit odd as they counter steer like a real motorcycle, so at really low speeds you need to turn the opposite of the direction you want to go. I still have the electric gyro version, but parts are really hard to come by these days. I would NOT buy any knockoff brand, period. It's more headache than you want, I assure you. Nuova Faor is the only one that still makes a decent MX / supermoto setup IMO.
