Yes, it is not uncommon to find some two-wheel wheelbarrows that need assembling. It is, however, worth noting that assembling a wheelbarrow is not a complicated task and should take little time. Some double wheel wheelbarrows such as the Suncast 2-Wheel Resin Multi-Purpose Cart can easily be assembled in less than 20 minutes and with no extra tools. However, some wheelbarrows may need a little more effort and extra accessories when assembling them. For example, assembling the WORX Aerocart 8-in-1 All-Purpose Wheelbarrow may take some more time as there are extra accessories when you want to use them in different ways.
