The gearbox will come separately from the motor and you'll have to put it on yourself. It's very easy to do but I would suggest you buy a little 100mm long 3 jawed gear puller for under $20 and a file because you will probably find that the key needs a bit of filing and the keyway in the centrifugal clutch is usually smaller than it should be. A bit of filing to get it all to fit nicely takes very little time and will make assembly and, more importantly, disassembly easier.
Gear pullers are a must have tool for these kits and so are some spare keys. It's the small key in the sprocket shaft that breaks most easily and it's easy to replace if you have a length of 3mm or 1/8" keysteel but it is time-consuming cos you have to take the gearbox off. The other keys are all 4.5mm and a length of that is always useful in case you need to replace any of those. The suppliers should have all these things as spares including gearbox gaskets but they don't. They carry nothing in the way of spare parts hoping to sell you a complete kit again! One other thing - it's a good idea to loctite the flange onto the freewheel sprocket to ensure it never comes loose. This was one of the best things I ever learnt with these drivetrains. There are pictures of the freewheel assembly on this thread:
