The Prime Karts Rumble Seat adds a rear passenger seat to compatible Prime pedal karts, allowing an additional rider to join the adventure. Built with durable materials to match the quality of the kart, the Rumble Seat securely mounts to the rear of compatible models while maintaining a comfortable seating position.

Its integrated footrests provide added comfort for passengers, and the sturdy construction is designed for dependable residential use. The Rumble Seat is engineered to complement your Prime Kart while preserving its original performance and handling.

The Rumble Seat is one of our favorite Prime Kart accessories because it lets younger passengers join the fun without needing their own kart. It's a great upgrade for families with multiple children and an easy way to get even more enjoyment out of a compatible Prime Kart.

Prime Karts offers several platforms designed for different rider sizes, household needs, and levels of use. Start by considering who will ride the kart, whether one or two riders need to ride together, and whether it will be used at home or in a higher-use setting.

XM-4

The XM-4 is the smaller Prime Kart platform and is designed for younger or smaller riders. Its more compact size makes it easier for growing riders to reach the pedals, steer comfortably, and maintain control.

XL-4

The XL-4 is the most versatile single-rider option for residential use. Its adjustable seating accommodates older children, teens, and many adults, making it a strong choice for families who want one kart that can be shared by riders of different sizes.

XL-4 PRO

The XL-4 PRO is the higher-use option for commercial and rental environments. Choose this platform when the kart will be ridden frequently throughout the day or used somewhere that requires construction and warranty coverage intended for commercial use.

XXL-4 PRO

The XXL-4 PRO is the tandem option for two riders. Its side-by-side design allows riders to pedal and steer together, making it a good choice for couples, siblings, parents with children, and families who want a shared riding experience.

Choose the Right Fit

Age recommendations are a helpful starting point, but rider fit is more important. The rider should be able to sit comfortably, reach the pedals through their full rotation, steer without stretching, and maintain control of the kart.

Use the adjustable seat to find the correct riding position before use. Review the individual product specifications for exact rider recommendations and weight limits.

Residential or Commercial Use

The XL-4 is intended for residential riding, while the XL-4 PRO is the appropriate choice for commercial or rental use. Select the model based on where it will be used rather than appearance alone.

Review the individual product warranty before ordering to confirm that the model is approved for the intended setting.

Where It Will Be Ridden

Choose a kart suited to the rider and the intended riding surface. Prime Karts should be used on appropriate, relatively level terrain away from traffic, steep slopes, hazardous obstacles, and unsafe riding areas.

Tire style and terrain capability may vary by model, so review the exact product details before purchasing.

Accessories

Compatible accessories may be available for select Prime Kart models. Accessories are sold separately unless the individual product listing specifically states that one is included.

Always verify compatibility with the exact kart model before ordering.
