Explore Any Trail This Summer with a Mongoose 24 Inch Girl's Bike The Mongoose Spire 24 inch girl's bike keeps your comfort as the number one goal with a flexing suspension system that will absorb the bumps and potholes on the trail. This frame is also made from aluminum, which is both durable and lightweight; the result is a reliable bike that is also easy to pick up and carry if you need to wade across a stream or toss the bike into the back of your SUV. Designed for riders who are 56 to 60 inches tall, this bike will be perfect when you go out on a mountain trail or when you just cruise down to the local ice cream shop. The Mongoose 24 inch girl's bike also provides multiple gears with a twister-style shifting mechanism so that you can switch gears quickly, without having to take hands away from the handlebars. You get maximum control and safety in any situation. The 3-piece crank powers 24 inch wheels, so this is a bike that can really get up to speed when you need it to.
