At Giantnerd we believe that great bikes should be affordable and accessible to everyone. We know that not everyone is a bike tech. Building and tuning a bike may seem like and insurmountable task, and a bike shop is not always available for assembly. This is why we created the Ready to Ride build. With the Ready to Ride build you receive a 99% assembled bike that goes from box to road or trail in about 10 minutes.

The Ready to Ride build offers:
  • Highly detailed 65 Point Assembly Checklist
  • Built by a Certified Pro who will sign the Checklist
  • Checked by multiple Certified Pros for quality
  • Build quality guaranteed (if not perfect we will fix it)
  • Typically ships next day
  • Only $50 (cheaper than your local shop)


We are so confident you will be 100% satisfied with your new bike, that we are going to let you ride your new bike for a full week risk free. That's right, risk free and we mean it.

To take advantage of this incredible offer, you just need to order the bike in Ready to Ride. Please contact our knowledgeable customer service agents at 877-731-6051 or if you are unsure which bike/size is perfect for you.

We do all this to make sure that you have the same experience, or a much better one, than you would have at your local bike shop. These bikes are top of the line, and our service and warranty are second to none. Let us prove it to you today.
