Order in a shop or online - in either case the bike is delivered to your local bike shop for assembly and check. As far as I can see, the discount is only available for the Large size. The bike is 2022 model, but I could not find 2023 nor 2024 model of Giant Trance with alloy frame in Australia.
There are discounts on other bikes as well, but not all sizes are available, or discounted.
From the description : "This versatile trail machine is built on a lightweight, stiff and super-strong ALUXX SL frameset that blends our latest Maestro suspension technology with adjustable frame geometry. The Advanced Forged Composite rocker arm has a flip chip that allows you to adjust frame geometry. Choose steeper or slacker head tube/seat tube angles and either a 35mm or 45mm bottom bracket drop to fine-tune the handling for your riding style and terrain. It’s designed around a 130mm travel suspension fork, and the overall geometry has been tuned to maximise its performance on rugged trails."
Amazing the huge pricing difference between L and the other sizes. I mean all the other sizes are $4999. How can they justify that $2000 more just because it's in a store instead of from a warehouse.
But with the L size. You even get free pickup with this at store when the bike is delivered from the warehouse to your chosen Giant store. Yes they ship it from the warehouse to the store (even interstate stores it seems) at no cost to you for pickup.
