We currently have limited capacity to build bikes in our warehouse. Due to this, we are limiting the number of bikes we sell per day and you might not be able to process your order at checkout. The count resets at 11pm every day so that would be the best time to try, although we do have a peak of attempts at this time so we can't guarantee a slot for everyone.
