What size child is the Kubbi K4 suitable for?
The Kubbi K4 is designed for children aged 3–7 years and around 80–130 cm tall. It has a seat height of 45 cm, which allows most riders in this range to place both feet flat on the ground — a key indicator of a safe fit.
To check at home, have your child sit on a chair or bench that’s roughly 45 cm high. If they can rest their feet comfortably on the floor with a slight bend in the knees, the Kubbi K4 will be the right size for them.
What speeds can the Kubbi K4 reach?
It has two speed options—8 km/h for beginners and 15 km/h for more experienced riders.
How far can the bike travel on a single charge?
It can cover up to 10 km per full charge.
How long does it take to charge the battery?
Charging takes approximately 4 hours.
What is the maximum rider weight and suitable age range?
The Kubbi K4 supports riders up to 40 kg and is designed for children aged 3 to 7 years.
Can the bike be used in wet conditions?
It’s rated IPX4 for water resistance, so it can handle splashes and light rain.
Is the Kubbi K4 suitable for off-road use?
Yes, it has durable 12” inflatable off-road tires perfect for varied terrain.
How long will delivery take?
We offer a 48-hour paid delivery option, or free standard delivery which usually takes 3-5 working days within the UK. Tracking details are provided for all orders.
