The Mini Chopper Bike 4 Stroke Engine

The mini chopper bike 4 stroke engine is considered to be a trendy, fast and sleek riding vehicle. The 4 stroke engine provides power and performance through one of the oldest and most respected engine types around. In fact, it is the most common engine-type seen today, as it powers most cars and trucks. It is interesting to note that it was first introduced by Otto in 1876!

Each cycle in the engine has four strokes and each stroke corresponds to one full stroke of the piston. So the mini chopper bike 4 stroke engine's cycle is completed with the four strokes of intake, compression, power and exhaust. Although larger 4 stroke engines usually boast having more than one cylinder, multiple camshaft arrangements, multiple valves, turbo chargers and even fuel injection, the basic operation of the engine remains the same.

The mini chopper bike 4 stroke engine is attracting a fan base throughout the world. The affordability, ease of transport, and basic safety (when all rules are followed) make them a very charismatic and popular item. It's essential to maintain your bike, as keeping it in good condition will ensure your safety and long-term use.

Mini choppers are considered to be works of art by enthusiasts everywhere. As they mimic scaled down versions of real motorcycles, they are appreciated for their function, speed, and appearance. Boasting quiet performance and fuel efficiency, they are not manufactured or approved for highway riding. It is imperative to follow the laws for your own state and to be aware of all safety precautions.

Popular in the 50's, the first mini bikes were fashioned by go-cart enthusiasts from spare parts and raced on go-cart tracks. The result was a small motorbike with a low frame on ten-inch wheels and elevated handlebars. The power train consisted of a small engine from a reel lawnmower with a chain drive and centrifugal clutch. Over the years, mini bikes have become much more specialized moving closer to the concept of a mini motorcycle.

Today a mini bike kit is still a fun and excellent family project and probably the only way to produce the original mini bikes. To buy a mini bike only the Baja Motor Sports Doodle Bug Mini Bike with a 97cc four-stroke engine, automatic transmission, and a top speed of 15 mph has the look and feel of the original mini bike. Other than this example, the closest thing to the original is the pocket mini bike.

The pocket mini bike, often called the "mini pocket rocket bike", is the mini bike of today. Designed to resemble a miniaturized street bike, these mini bikes can provide kids and adults with the experience of a motorcycle ride without the cost or age/size requirements of its full sized counterpart. A typical pocket mini bike is about a fourth the size of a motorcycle at about 20 inches tall, 38 to 47 inches in length, and weighs around 50 lb (23 kg). Powered by a 40–50cc (2.4–4.2hp) two or four-stroke engine, speeds are about 20 mph; however, expensive racing models with larger engines can attain speeds of 78 mph (126 km/h).

The next step up in size and cost are the mini pit bikes and mini dirt bikes. Originally designed for racing on the pit roads inside motocross tracks, the mini pit bike is very similar to a mini dirt bike and the names are often used interchangeably. Mini dirt bikes, as the name suggests, are smaller versions of regular-size dirt bikes with less power and are suitable for children and adults. The major differences between the pit or dirt mini bikes and the pocket mini bikes are the addition of front wheel suspensions to allow for off road use or dirt track racing absorbing the shock from bumps and jumps. Some models also include a seat or rear wheel suspension system. Compared to full size dirt bikes, these bikes are comparatively inexpensive and are perfect for beginners.

Chopper mini bike models, named for their street equivalent, are mostly larger and built for speed. A small-engine model (two stroke/49 cc) is suitable for a teen with a top speed of 30 mph. The four-stroke, 49 cc model has a top speed of 50 mph. With any larger engine, 90 mph is common.

All of the designs described above are available with electric motors. Electric mini bikes have top speeds significantly slower the gas-powered models. Most electric mini bikes are limited to speeds of about 20 mph making them safer for children and beginners. Although prices tend to be lower, the difference is not great.
Prices range from $180-$600 for mini pocket bikes, $250.00-$1500 for mini pit or dirt bikes, and $400-$2000 for mini choppers.
