The Haro MS4 20 x 2.1 front and rear tires are made to absorb hard landings. The Weinmann 48H alloy rims that go with the tires help add to the bike's sturdiness, as do the set of steel pegs that reinforce each tire. The Haro Stripe Grips that come stock with the Haro F3 also increase the solid feel of this bike. These grips help the rider feel securely in position when performing stunts. The reviews of the Haro F3 have been generally positive. However, like other bikes in this product line, there is the common complaint that this bike is a little too bulky.
