Are you having trouble looking for an MTA bus for GTA 5? Well here it is. Here are MTA bus textures for SCPDArmor23's Orion VII models that you can use whenever you are in New York. And yes, these buses actually exist, but without the bike racks. Cause usually when I spawned the bus, it always spawns with the bike rack attached. To remove the bike racks, simply use a trainer and then choose "Remove Hood", which will remove the bike rack.
