If you’re in the market for an entry-level dirt bike but with a bit of grunt, then you really have to check out our OneMX™ Design EX1S OneMoto Teen 500W Dirt Bike 36V LI. This is our latest edition value-for-money dirt bike exclusive to OneMoto

If you were to speak to anyone on the street about dirt bikes, the first thing to come to mind would probably be petrol dirt bikes, right? However, what a lot of people don’t realise is, just how much the battery prices have come down in price. They are also becoming a lot more efficient which in turn means they are becoming more popular.

Now, the EX1S looks just as good as its petrol counterpart and they provide considerably more torque meaning the riding pleasure is almost instantaneous.

Don’t forget, these awesome bikes don’t have a heavy engine to carry around which makes them much, much lighter and nippier in those tight turns.

The speed is pretty impressive, reaching up to 24Kph. That’s not all, the EX1S is also equipped with heavy-duty front and rear disk brakes so braking rapidly won’t be a problem for those tight spots.

With its rear mono-shock absorbers and front hydraulic inverted forks, your teen is guaranteed a fun ride, but also a smooth one too!

RiiRoo also offers free delivery to the United Kingdom and can offer a next-day service as long as you order by 1 PM.

    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.

    Every mini racer boys dream!

    Quick delivery and a brilliant product, our son absolutely loves his bike and feels like a real racer! The battery seems to last for a lot longer than the advertised time and the ability to limit the top speed with the key is so much safer for new riders.
    I would take the age/weight rating with a pinch of salt, perfect for our 7 year old but far to small for our 11-year-old.
    Would've been a firm 5 star review if the assembly instructions were better, the photos/instructions were for a different type of chain adjustment setup, which confused us a little bit. As complete newbies to assembling a dirt bike, and feeling the pressure of a 7 year olds excitement, it did take us a good few hours, a message to customer support (responded within 24hrs) and a lot of you tube research to get it put together properly. A bike assembly video in the support pages would've been such a help, we could only find videos for the electric cars.

    Hello Leon

    Thank you for taking the time to leave a review for our OneMX™ | EX1S | 36V Lithium | 500W | Dirt Bike. We are thrilled to hear that your son loves his new bike and that it has exceeded your expectations with its longer battery life and safety features.

    We apologise for any confusion you experienced with the assembly instructions. We appreciate your feedback and will take it into consideration for future improvements. We are glad to hear that our customer support team was able to assist you and that you were able to find helpful resources online.

    We hope your son continues to enjoy his new dirt bike and we look forward to serving you again in the future.

    DO NOT BUY!!

    The bike came damaged.
    Bolts were not screwed in, clearly no quality control at point of manufacture or with the riroo team. God knows what else they forgot to do or just overlooked for speed during the manufacturing process. It’s unbelievably scary when it’s your child’s safety at stake. I am still awaiting a resolve after 6 days for an 11 year olds present.
    I am being made to jump through multiple hoops which is ridiculous under the circumstances.
    Don’t put yourself through the emotional strain and don’t see your child upset when they can’t ride a possibly dangerous bike when it comes in the same condition as ours did.
    Purchase a quality product from a different source.

    Hi Ryan,

    I sincerely apologize for the inconvenience with the damaged bike. I'm sorry for any frustration this may have caused. Our colleagues have arranged a collection and replacement for you. Please keep in touch, and we'll ensure a swift resolution. Thank you for your understanding.

    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.
