Don't worry, we have thousands of products for you!
This bicycle comes in a well protected box, about 90% assembled. The most complicated is already mounted from the factory and the rest is quite easy to do. You will only have to place the seatpost, the saddle and adjust the handlebar and the derailleur (if there is one).
If you do not feel confident to finish the assembly, we recommend you take the bicycle to a nearby bicycle store/workshop for a specialist to complete the bicycle build.
