I suggest having Ride-On put in tires(front and rear). Most all bike shops carry it, and majority of bike shops recommend it instead of traditional weights. Can easily do it yourself.....purchase an 8oz. bottle, remove valve stem and squeeze in from the plastc bottle 40z. in each wheel, install valve stem and air tire up. Not only balances wheel/tire, but also eliminates a flat tire. Believe you can still Google the product for more info and video demonstration. Has worked fine for my bike for some 3yrs. now.
