  • Delivery to the United Kingdom is on a next day service as long as you order by 1 PM and it is included in the price :)

    Delivery to Northern Ireland is a 2-3 day service; however, this will incur a surcharge :(

    Please Note: Shipping orders and returns outside of the UK will incur a customs fee, so please be sure to factor this in when ordering or returning items.

    Given the varied sizes of the products on offer, we are unable to calculate shipping for you at checkout, therefore please contact our support so they can get a delivery price for you. 

    As an alternative, you can checkout as usual and wait for our customer service team to get in touch with you to provide a quote. 

    We also can ship to most European countries; however, you will need to contact our customer service team for a delivery quote.

    Most of our products will be delivered using a specialised carrier service, and because of this, it is essential you have someone to accept delivery on the scheduled date specified.  A failed delivery will incur additional charges :(.

    Now that we have started selling Petrol dirt bikes, buggies, and quad bikes, we thought it would be a good idea to provide an explanation of the different age ranges that these toys are suitable for.

    Providing a specific age range for these toys is extremely difficult, due to the fact that children come in all different shapes and sizes. Also, what is deemed acceptable to one parent isn’t acceptable to another.

    For that reason, please take this as a rough guideline of the ages these toys are suitable for. It goes without question that the suitability of each product we sell is at the parents discretion. The weight, height and skill level of the person using the toy also needs to be considered.

    We Have 2 Main Categories of Bikes - Dirt Bikes & Pit Bikes

    Pit bikes are generally smaller than dirt bikes in appearance and features. This makes it difficult to choose an appropriate bike since there are so many different varieties of bikes. 

    We ask that you take care when ordering your bike to ensure it is the right weight, height and power and features you are looking for.

    The Pit and Dirt Bikes have a minimum user age of 15+. These are extreme guidelines and will vary depending on the height, weight and skill level of each child.

    We Have 3 Main Categories of Quad Bikes

    There are no maximum ages for these quad bikes. However, OneMoto has a guideline for minimum age use.

    Mini Quads

    These quad bikes are designed for children from the age of 7 and upward. The suitability of each product we sell is at the parents discretion. The mini quads range from 250w to 500w in the electric range and 50cc - 80cc in the petrol range.  We will have more powerful versions under the same category, however, based on customer feedback these should be reserved for much older kids and adults.

    Kids Quads

    These quad bikes are designed for children from the age of 10 and upward. The suitability of each product we sell is at the parents discretion. The child quads range from 500w - 1000w for the electric range and  50cc - 250cc for the petrol range.

    Adult Quads

    There really isn’t a minimum or maximum age for the adult quads, so there was no need for us to set any other guidelines for them other than they are designed specifically for adult use. The adult quad bikes range from 150cc+.

    Buggies & Go Karts

    There are no maximum ages for these buggies and go karts. However, OneMoto has a guideline for minimum age use which is 6+. With this, let us stress that this is purley at a parent’s discretion. Bear in mind that these are pretty powerful machines.

    Couldn't have asked for more.  It got delivered in 2 days and it is exactly what they said it would be! The manual was missing from the box and their support sent it electronically within the hour!

    The choice of products on offer is reason enough to spend hours on their website.  I must have watched at least 30 product videos before I pulled the trigger.  Quick Delivery and a good product.
