The MotoTec pocket bike powered ride on is the ultimate kid or adult ride, great for driveway and parking lot fun, cruise around cones, and speed through trails with ease. Comes standard with front and rear disc brakes and large 11-inch pneumatic street tires. Safety first - always wear your helmet and all safety equipment and observe safe riding rules. A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air.
