Ideally we recommend professional assembly by a qualified mechanic to ensure you get the best life out of your bike. Most of our cargo bikes and all of our Bromptons ship fully assembled. Linus and Surly bikes ship partially assembled.
If you are a confident home mechanic then go for it! You will need the right tools and some bike grease in order to do this correctly. We do recommend however, that you take your bike to a qualified bike mechanic for a check. If at any point you feel unsure we recommend to get in touch.
