Stroller Recommendations

Hello! I'm looking for stroller recommendations. One that is lightweight, can auto fold and have a carry on strap. On days that my husband is working and cannot drive us, I would need to take a bus/mrt with my almost 2.5 year old toddler. So I was thinking of folding and carrying the stroller while I hold my toddler's hand and let him walk up the bus, but let him sit in the stroller while he's in the MRT so he won't run around (you know.. toddlers can be active).
