    Easy Assembly

    When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

    Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

    • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
    • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
    • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
