Yes, but you'll need to buy some stuff.
The crankset that comes stock on our complete bike will accommodate a 74mm bolt circle granny ring. You'll need a 74mm BCD chainring, some bolts and spacers for it, and a longer bottom bracket (think 118ish) . You can probably get this done for around $100 at a bike shop. The stock shifters and front derailleur will work fine with it
