  • This size table is only an estimation, the optimum frame size depends on your personal preference and riding style.

  • All bikes purchased from iRIDE will have been pre-assembled by our mechanics and test ridden. You will also receive a multi point checklist of all the safety checks and bike build elements we work through to ensure you bike is correctly assembled, and then tested so that it runs as it should. Bikes being sent to a customer who is unable to collect it from iRIDE, will have it boxed, wheels, saddle and bars generally off and re-packaged.

    The delivery of bikes will be organized once a freight fee can be determined based on weight and delivery location.

    Assembly should take no longer than 10-20 minutes. It is recommended that a skilled mechanic assemble, or check the bike. If possible your local bike shop is likely best placed to do this from a safety perspective to ensure all is as it should be. If a rider is having any issues we can hook up an online video chat, or talk over the phone. If this service is required email us at to organise a time that suits all parties.
