Bike Freight Charges

This is a door to door service but depending on the delivery location, the total freight charge may additional charges per bicycle. You will be notified before we process your order if an additional freight charge applies to your order. This normally only applies to remote areas, outside of major cities.

Online Bicycles Orders

Please allow 3-5* working days for your bicycle to be delivered from time of payment being received. We take extra time and care in assembling your bicycle before it is packed and ready to send. Most online bicycle and department stores simply send the bicycle to you without any adjustments. We make sure the gears, brakes, wheels and all other components have been adjusted correctly first. All you need to do is fit the pedals, front wheel and stem. Easy to follow assembly instructions are included.
