Ask us anything else
Which rigs does it fit?

The wood base has five hole positions, one per inner width (the clear width between your two verticals): 500, 540, 555, 580 and 600 mm. The SPEC 282 is 540 mm. Measure yours before you order; if it isn't a 282, send us the number and we'll tell you whether one of the positions matches.

How old, how tall?

It's sized for children about 110–140 cm tall, roughly ages 4 to 8. From around 125 cm the seat support comes off and only the pedal platform stays.

Do I have to move my pedals every time?

No. Put a spare set of pedals on the platform and the whole platform lifts off in one piece when it's your turn; your own pedals stay where they are. You can also run one set of pedals and swap them across, but that means undoing bolts each time.

Does my own driving position change?

No. Lift the platform off and the rig is exactly as you left it: seat, pedals and wheel where they were.

Are pedals included?

No. The kit is the platform, the seat and its wood base. The platform takes most pedal sets.

What's in the box?

The pedal platform, the fiberglass bucket seat with its cushion, and the seat's wood base. Pedals are not included.

Preorder: when do I get it, and can I cancel?

You pay in full at checkout. You can cancel for a full refund any time before we ship. It ships from China (the estimate is end of October) and we confirm your date by email.

Is it safe for my kid?

Here is what it is: a fiberglass bucket seat with a cushion, bolted to its wood base, and a pedal platform that locks in place on a quick release and lifts off as one piece. It's a driving seat for a child on a real rig, so treat it like one: adult supervision recommended.
