We spend extra time and care building, testing and re-boxing your bike before it leaves. This takes approximately 5 business days beyond the ship date shown on this page. This extra step and time allows us to ensure that when your bike arrives to you it will be very easy to assemble for most anyone. Most bikes do not include pedals, so make sure to choose some for your new bike so we can ship them in the same box and you can get our riding quicker!The ECR is Surly's ultimate off-road touring machine.
