Shipping options (choose option at checkout once added to cart):

1. Ship to home ($150)

If your order includes additional items, they may arrive separately from the bike. We highly recommend taking your bike to a local bicycle mechanic if you are in any doubt when attempting assembly. If you decide to take your bike to a 3rd party for assembly or check over of your own work, additional fees will apply and these are at your own expense. If any damage is evident to the box when it arrives please take photos and contact us prior to attempting assembly.
