Powerful electric PitBike for off-road riding

This PitBike’s strength becomes apparent especially when riding off-road. The electric motor delivers power smoothly and quickly, so the motorcycle responds immediately when the throttle is turned. Good acceleration makes the ride dynamic and helps tackle different types of terrain – whether it is a gravel road, forest trail, or more uneven ground.

The electric drive also has a practical advantage for off-road riding: the ride is quieter than with a conventional internal combustion motorcycle. This makes the PitBike a suitable choice for those who want to practice their riding skills and explore the terrain with less noise.

Different speeds according to the rider’s skills

The motorcycle allows you to choose between different speeds, helping adapt the ride to the rider’s experience, the terrain, and the situation. When starting to practice, it is sensible to choose a calmer pace and gradually move to a higher speed once steering and braking are firmly under control.

The speed can reach up to 85 km/h, so this is a capable vehicle that must be used responsibly. Before riding faster, a teenager should learn how the motorcycle behaves, practice safe braking, and always take the terrain conditions into account. The speed should be chosen so that the motorcycle remains under control at all times.

Large battery for longer rides

The large battery supports a longer and more flexible riding day. This is an important advantage when you want to do more than one short practice lap or move between different sections of terrain. Battery life is always affected by riding style, selected speed, terrain, and load, but a larger battery provides more opportunities for riding.

When using an electric motorcycle, it is important to monitor the battery charge and care for it according to the manufacturer’s instructions. This ensures that the vehicle is ready for the next ride and that the battery retains its reliability. Before heading out, it is worth checking that the battery is sufficiently charged and that all connections are in good condition.

Well-functioning suspension and more comfortable handling

When riding off-road, much depends on how the motorcycle handles uneven surfaces. Well-functioning suspension helps keep the ride under control and makes passing over holes, roots, and other obstacles more comfortable. It also supports the rider’s confidence, as the motorcycle does not react sharply to every uneven surface.

The suspension’s capabilities should always be assessed together with the rider’s skills and the riding environment. The correct riding position, appropriate speed, and attentive observation of the trail are just as important as the motorcycle’s technical features.

Easy to maintain and convenient to use

Maintaining an electric PitBike is easier compared with an internal combustion motorcycle because there are no conventional engine oil and fuel-related procedures. In everyday use, however, it is still worth regularly checking the brakes, tires, chain, fasteners, and controls. After off-road riding, it is advisable to clean the motorcycle and inspect areas where sand or mud may accumulate.

Safe riding always requires a helmet and other appropriate protective equipment. You must also comply with applicable traffic and off-road riding rules and use the motorcycle in a suitable location.

The powerful electric PitBike motorcycle combines quick response, a speed of up to 85 km/h, a large battery, and effective suspension. It is an interesting choice for a teenager who wants to improve off-road and values simpler maintenance and different riding modes.

Iron Baltic products are designed for practical use in demanding environments. Each product starts with input from ATV and UTV users and vehicle manufacturers, then moves through prototyping, testing and further development before production. This hands-on process helps ensure that the equipment is built around the requirements of the work it is intended to perform.

The range available from Iron Baltic includes equipment for vehicle protection, mounting and utility work. Depending on the application, this can include skid plates, front and centre mounting adapters, receiver-mounted ploughs, potato ploughs and other agricultural attachments, forestry equipment, winch accessories, support wheels, front baskets, push tubes and replacement components.

Iron Baltic’s products are developed and tested through Estonia’s changing seasons. Skid plates and protective equipment are tested in conditions ranging from summer heat to freezing winter weather, while winter, forestry and agricultural products are used in cold temperatures, dense forests and seasonally changing fields. This practical testing approach is intended to support reliable performance in the conditions where ATV and UTV accessories are used.

Whether you need a model-specific mounting solution or a versatile attachment for work around the property, farm, forest or outdoor site, Iron Baltic offers equipment designed to extend the practical capabilities of your ATV or UTV. Browse the available Iron Baltic catalogue to find accessories and auxiliary equipment suited to your vehicle and application.

Iron Baltic is one of the largest manufacturers of accessories and auxiliary equipment for all terrain vehicles (ATVs) and side by sides (UTVs) in Europe. The company was established in 2006 in the tiny Northern European country of Estonia by two friends with the aim of helping people make the most of their ATVs. We started locally with custom ATV skid plates and have since rapidly expanded both our product line and availability. Currently, our range includes more than 200 model-specific products as well as an ever expanding line of universal products.

We have, however, stayed true to our original hands-on production cycle. All of our products are designed from the ground up based on input from users and vehicle manufacturers. The designs are carefully prototyped, thoroughly tested, improved, and tested some more. Only when we are sure the product fully meets the requirements for which it is built, will we start production and even then we will do our best to develop the products further based on future user suggestions by altering designs and adding improvements.

The four distinct seasons in our country guarantee that every product shipped to our customers has been rigorously tested under the extreme conditions they are meant to be used in. This means that our skid plates have seen action from scorching summer heat to freezing blizzards to everything in between, our winter product line has been thoroughly tested in the cold Estonian winters, and our forestry and agricultural products have seen countless hours of action in our dense forests and seasonally changing fields.

We value and rely on user feedback to keep our product development current and relevant. If you have experiences with our products or ideas for something completely new, we would be more than happy to hear from you. Please let us know by sending an e-mail to feedback@ironbaltic.com, filling in the form on our contact page or dropping us a line on our Facebook page.

Powered electric motor for starting passenger

APOLLO Children's PitBike Tiger EMD07 1500W 48V The Lithium 14-12 uses a 1500 W electric motor, which gives the young rider enough strength for various off-road races. The electric motor operates quietly and makes the use of the wheel convenient both in the cross lane and in suitable terrain, where the child can develop driving skills calmly.

The maximum speed of the wheel is 40 km/h and can be limited. The limitation option is especially practical for a starting rider as the driving experience can be gradually developed as the child’s skills and confidence grow. So the bike doesn't have to use its full potential right from the start.

Who's Tiger for?

According to the manufacturer’s data, the wheel is recommended for 8- to 14-year-olds and the maximum recommended mass for a rider is 60 kg. It is a single-seat offroad bike designed for one child at a time and suitable for a young person who wants to learn the basics of cross-country driving.

Age, however, is only one starting point. Before buying, it is also worth considering the child’s height, driving experience, coordination and whether he or she can independently control the wheel. On the first trips, an adult should always be nearby and the driving environment should be controlled and isolated from traffic.

The advantages of Li-Ion battery and electric driving

The 48 V Li-Ion battery offers a convenient and modern solution when using an electric cross-wheel. Lithium-ion technology is lightweight, fast-rechargeable and allows you to enjoy long journeys on a single charge. The battery has also been described as being less sensitive to temperature fluctuations, which helps make use more flexible under different conditions.

An electric motor does not require fuel refueling, and the driving experience is quieter than that of a petrol-powered cross-country bike. This means that the young person can focus on learning to drive, and it is easier for the parent to observe how the bike behaves on different ground.

Suspension and durable structure

It is not only the power of the engine that is important to cross-country driving. In rough terrain, high-quality amord systems help to make movement smoother and more comfortable by absorbing some of the impact of the soil. This is important for the starting rider, as a more stable and controllable wheel will help to maintain the driving position better.

Tiger's strong frame and durable tires are designed for adventurous use. Therefore, the bike is suitable for rides in the forest, on suitable tracks and other terrain where permitted and safe conditions are available. After the ride, the bike should be inspected, cleaned and checked that the essential parts are in order.

Safe start and informed choice

A safe ride starts with the right equipment. Helmet, goggles, gloves, strong driving clothes, and knee and elbow protectors help reduce the risk of injury. The child should learn to brake, adjust speed, turn and stop the wheel before driving more independently.

APOLLO Children's PitBike Tiger EMD07 1500W 48V The price of Lithium 14-12 is 895 euros. The bike is accompanied by a maintenance book to help monitor maintenance operations consistently.

If you want an electric cross-wheeler for your child that combines a 1500 W engine, with a limitation of 40 km/h top speed, a 48 V Li-Ion battery and a durable off-road build, the Tiger is a strong candidate for the first serious vehicle. With the right equipment, guidance and a suitable driving environment, it becomes an exciting companion with which to develop skills and enjoy the joy of mobility.

Athletic pit bike for adolescents

The Pit bike is a compact and sporty vehicle that offers the opportunity to develop a driving experience and enjoy active leisure time. PIT BIKE STORM X PRO 8000W 72V LITHIUM 35AH It is designed especially for adolescents who like to move, try different landscapes and get more from driving than just getting from point A to point B.

It is an electric model powered by a powerful electric motor and a 35Ah 72V lithium battery. The electric solution makes the driving experience quieter compared to the pit bike with an internal combustion engine and is suitable for recreational use where excessive noise is to be reduced. At the same time, the pit bike retains its sporty structure and active driving position.

Powerful electric power train

The model designation highlights the 8,000 W power, 72 V system, and 35 Ah lithium battery. These indicators describe the electric power of the vehicle and give an indication that it is not a small electric vehicle designed for calm running. The power of an electric motor makes driving more vivid and supports athletic use.

A lithium battery is a practical solution for a user who appreciates the simpler nature of an electric vehicle. It is not necessary to deal with the normal operations of the fuel or internal combustion engine to start the ride. It is important to follow the instructions for loading and use and to take into account that the vehicle must be used responsibly and in a suitable environment.

Strong frame and effective suspension

When driving off-road, a powerful power source alone is not enough. The design and suspension of the vehicle are also important. PIT BIKE STORM X PRO 8000W 72V LITHIUM 35AH is equipped with a strong frame that supports sporting use and helps the vehicle to behave confidently in various situations.

Functional shock absorbers help make driving on uneven ground more comfortable. The terrain may encounter bumpy tracks, soil of varying hardness and smaller obstacles. A well-functioning suspension helps to absorb such changes better and allows the rider to focus on handling and driving experience.

Diverse use in different terrain

One of the strengths of this pit bike is the ability to use it on different terrains. The model is designed to handle both recreational track and uneven ground, where the vehicle is expected to have good handling and sufficient strength. This makes it a suitable choice for young people who want to spend their free time actively and discover the possibilities of driving outside the normal roads.

However, the driving position must always be chosen according to the skills of the user and the purpose of the vehicle. Before driving, it is worth checking the user manual, checking the condition of the vehicle and making sure that driving is allowed in the specific area. On public roads and in the vicinity of other road users, applicable requirements must be observed.

A safe and responsible driving experience

The sporty pit bike offers a lot of pleasure, but its capabilities also mean the need for thoughtful use. The adolescent should drive under the guidance or supervision of an adult, especially when the vehicle is still familiar. Before each race, it is wise to check at least the following items:

• the general condition of the frame and handlebar;
• operation of shock absorbers and other moving parts;
• operation of brakes and controls;
• the maintenance of the battery, connections and charging devices;
• use of appropriate protective equipment.

Helmets, gloves, suitable driving equipment and other protective equipment help reduce the risk of injury. It is also worth learning about the ability of the vehicle gradually, starting with easier terrain and calm driving.

PIT BIKE STORM X PRO 8000W 72V LITHIUM 35AH Suitable for a youngster who is looking for a pit bike for athletic entertainment and appreciates the quieter nature of the electric powertrain, strong frame and functioning suspension. With the right equipment, suitable driving and responsible use, it offers the opportunity to make leisure time active and exciting.
