Dirt Rocket Electric Motocross Bike Reviews Operating times are directly affected by the type of mini dirt bike you are operating. With gas-powered bikes, the limiting factor is the size of the gas tank. Generally speaking, the bikes we tested had an operational time of approximately 20 minutes for a full tank of gas. Tank sizes can vary, but most feature a 0.2 gallon tank. This makes gas-powered bikes ideal for experienced, long-term dirt bike riders who do not want to take a break and intend to spend hours on the machine. Simply top up the fuel tank and your child is off to the races again. This is very different from electric mini dirt bikes. Electric dirt bikes function on a charged battery that is charged through a standard 120V power outlet. Charge times differ, but tend to range between 9 and 12 hours for a full battery. This battery can be operated at full speed for up to an hour, but requires a full recharge cycle before the bike is ready to go again. This makes electric dirt bikes great for beginners who intend to use the bike every once in awhile for an hour or so. If your child wants to spend more time than this on their dirt bike, electric bikes may not be the best choice since they will be forced to wait for the machine to recharge.
