More like half an hour to 40 minutes. A basic boxed bike build involves putting handlebars into stem, inserting front wheel, aligning stem, installing seatpost and saddle, adjusting derailleur set screws and cable tension, centering brakes. 25 minutes unpacking and assembling, 10 mins test ride, 5 min additional adjustments.
