When will you ship my order?

Before we can ship your new bike, it needs to go into our workshop to be PDI'd (Pre-Delivery Inspected), during this inspection our mechanics will check everything is setup and ready to go - this can take a little time so on busy days or during sale periods it might take a day longer to process.

Is this bike in stock?
We only make available for sale products we have in stock, we do not remote warehouse products from suppliers as other stores do.
Our inventory is live except for bikes which are subject to up to a 24hr delay as our retail stores' inventory system is a bit archaic and requires a manual sync.
