Please note with our Pre-Assembled models we can not accept returns due to them being built so please ensure you've made the right choice prior to checking out. 


  • You save £99 on our usual assembly fee.

  • The Bike you have purchased comes pre-assembled (unlike the other ride-on cars we sell on the website).

  • It has been fully tested to ensure everything works as it should.

  • Means you don’t have to take time to assemble it. 

Note: This will be delivered on a pallet (UK mainland only) which means this probably won’t be delivered in a box. If it is for a birthday present you will need to make your own arrangements regarding the boxing of this car.

As an alternative, you can purchase one of our outdoor covers to cover the vehicle and give them a proper car reveal! :)


If you’re looking for a reasonably priced petrol motorbike for your kids, then our latest OneMX™ PX1S OneMoto Kids 50cc Petrol MotorBike has surely got to be on the list. This is the perfect 50cc starter motorbike. With this latest generation of 50cc mini bike engines, we’ve found them to be a lot more torquier and faster, and in turn, they are a lot more reliable. Probably the best value for money entry-level petrol bike we sell here at RiiRoo. The PX1S OneMoto Kids 50cc Petrol MotorBike is so much fun and really easy to get going. It’s going to be hard work prizing them away from their new toy. The great thing about this model is the upgraded grippy tyres and flexible suspension. Reaching speeds of up to 15 mph and with that 2 stroke air cooled engine, this really is a terrific first petrol motorbike your kids will enjoy for years. This bike is suitable for both wet or dry conditions, so there’s no need to pull them in early if it starts to rain. Assembly is required for this quad and you would also need to apply any stickers upon delivery. RiiRoo also delivery to the United Kingdom and is on a next day service if you wanted to upgrade.
