How does my bike come delivered?

How long will it take to receive my order?

Standard shipping normally takes 3-5 days. Express shipping is available on all small domestic orders (for an additional charge). 

Bulky freight such as E-Bikes will typically take substantially longer to deliver as more manual handling is required so with this in mind on average to most major cities is approx a 5-10day's. For more rural areas, NT, WA or TAS you could expect to see 14 days or more for your order to arrive.

International shipping times depend on the products and destination.
