So I recently got a new bike, its Canadian Tire brand, so its not that great but I am just getting in to biking so I think it will do. Anyway, I brought the bike home and noticed that when I hold the front brakes there is some movement in the place where the fork goes through the frame. I didn't think this was normal so I removed the handle bars and then the nut thingy on top and took out the fork and a lot of balls from a bearing poured onto the floor. Im not going to look for all of them so I was wondering If I can buy a whole new bearing system thing for the front , if so how much does it cost to get it installed?

Thanks in advance!
