EVA tires

• These are solid, foam-type “whisper” tires that cannot puncture and require very little maintenance. 
• Because they are solid, they tend to provide less ride comfort and grip compared to pneumatic tires. 
• You’ll typically find EVA tires on BERG’s smaller go-karts or those designed for younger children. 

Pneumatic tires

• These are air-filled, so they give better shock absorption, ride comfort, and grip, especially on uneven surfaces. 
• The downside: they can puncture and require occasional air pressure checks. Bergtoys
• BERG uses pneumatic tires for its larger go-karts (XL, XXL) to give more comfort during longer or rougher rides. 

Bottom line / when to choose which

• If you want low maintenance and worry-free tires for smooth surfaces, EVA is a strong option.
• If your child will ride over grass, gravel or uneven terrain and you want better comfort and grip, pneumatic is better.
• Always check the specific model’s product page to see which tire type it uses

Choosing the right go-kart involves matching your child’s age, height, and intended riding terrain. Here’s how BERG frames the guidance:

• BERG offers models starting as young as 2 years old up through adults. 
• Each model includes a recommended age range and height/length indications to ensure ergonomic comfort and safe operation. 
• For example, their XL go-karts are suited for riders from 125 cm to 190 cm, while XXL frames extend up to about 210 cm. 

Consider also the drive system (see below), terrain (e.g., pavement vs. grass), and accessories (passenger seats, trailers, etc.) when selecting a modelTip: If your child is taller or shorter than typical for their age, prioritize the height/length guide over age.

• Check tire condition (for pneumatic, also air pressure). 
• Tighten any loose screws or bolts. 
• Inspect the steering for smooth operation; lubricate bearings if needed (silicone spray is often suggested). 
• Test the brake / emergency stop function; make sure brakes operate cleanly. 
• Clean the kart (frame, plastic parts) to avoid dirt buildup and corrosion. 

• Frame: Clean regularly and check for damage or rust. 
• Wheels/tires: Check for wear, damage, and pressure (for pneumatic models) as per specs (e.g., 1–1.5 bar). Y
• Steering: Ensure steering bolts/nuts are tight and bearings are well-lubricated. 
• Drive chain / mechanism: lubricate chain, inspect for wear, and ensure it is correctly tensioned. 
• Plastic parts, seats, accessories: Inspect for damage, clean, and tighten or replace as needed.

• BERG offers spare parts (except frames) so that many repairs or replacements (flat tires, broken chains, lost parts) can be done without discarding the entire unit. 
• For significant structural repairs, contact an authorized dealer. Keeping current with checks and maintenance ensures that your go-kart remains safe and fun for years.

Yes — safety and certification are core parts of BERG’s design process:

• All BERG go-karts undergo extensive internal testing (materials, ergonomics, mechanical safety) during development. 
• External testing agencies then verify the results before models are launched. 
• Every model carries the CE mark, and many of the smaller models also carry TÜV certification. 
• The materials used are tested to be free from toxic chemicals and meet BERG’s internal quality standards. 
• Additional safety features:
• Many models include stable four-wheel designs and swing axles to keep traction and balance even in corners. 
• For child models, simpler drive systems (like Direct Drive) help ensure predictable, easy braking. 
• Manuals often specify that children under a certain age (e.g. under 12) should be supervised. 

In short: yes, BERG go-karts are certified, tested, and designed with safety in mind.

Durability is one of BERG’s key selling points. Here’s what they highlight:

• BERG uses sustainable, high-quality, non-toxic materials and tracks the source of each component to ensure a long-lasting product. 
• Many models carry a Cradle to Cradle certification, reflecting their approach to sustainable design and longevity. 
• They provide spare parts for nearly every component except the frame, so if something wears out or is damaged (e.g. tires, chains, plastics), you can replace it rather than discard the whole kart. 
• The user manual explicitly states that with a bit of care and periodic maintenance, a BERG go-kart “will last for a very long time.” So yes — with proper care, you can expect a long, durable life from a BERG go-kart.

The Direct Drive is one of BERG’s drive systems, mainly intended for younger or simpler models. Here’s how it works:

• In Direct Drive, the pedals are directly linked via a chain to the rear axle, so the moment the kart moves, the pedals move as well. 
• Because of this direct linkage, pedaling is straightforward, and braking can be done by simply stopping the pedal motion (i.e. holding pedals still). 
• It’s especially useful for young riders who are still learning coordination, because there’s no freewheeling — the connection is immediate and intuitive. 
• Note: BERG also offers their BFR drive system (Brake / Freewheel / Reverse), which is more advanced — it lets users pedal, brake via back-pedaling, and even pedal in reverse.

• For little kids or models where simplicity is priority.
• When you don’t need reverse or freewheel operation (i.e. pedaling doesn’t come off when you stop).
