Choosing the Best Girls Mountain Bike
When choosing the best girl’s mountain bike, it is all about the fit. Many parents are tempted to purchase a larger bike for their child to grow into. However, bigger bikes pose safety problems. A child’s feet may not reach the ground. Also, larger handlebars make squeezing the brakes quickly difficult. If the child cannot effortlessly control the bike then they risk crashing and possible injury.
Here are a few things to consider when choosing a bike that fits your child:
- Stand-Over Height: Make sure your child can straddle the bike with both feet flat on the ground.
- Seat Height: Yes, both seats are adjustable. Ideally, the balls of the child’s feet should touch the ground while they are seated on top of the saddle.
- Reach: The child must comfortably reach the handlebars. Ideally, their elbows must appear slightly bent as their hands grasp the grips and remain fully seated in the saddle. It goes without saying that the child must effortlessly control the handbrakes from a seated position for optimum safety while riding.
Bike Weight and Build
Sure you want to purchase a durable bike, but weight remains a factor. A girl might have a difficult time controlling a heavy bike as it sails up or down a trail. A lightweight design provides more manageability for a child. Steel construction might stand up to the years, but an aluminum frame offers more maneuverability and handling benefits.
The Importance of Gears
Sure, on pavement single speed bikes work fine. However, an off-road mountain bike requires gears. All of the climbs and descents of a backcountry trail require a gear range ratio for easy and safe riding. Some kids’ bikes have 27 gears which tend to be overkill because the numerous gears become confusing. Plus, the gears are added weight to the bike. Ideally, a child benefits from having seven to nine gears when riding off-road. However, if your child is an experienced mountain bike enthusiast then a higher gear ratio could prove beneficial.
Shifters: Grip Shifters or Trigger Shifters
Kids have different skills when it comes to shifters. Some youngsters thrive with grip shifters and others can master the trigger shifter. If you are unsure of which one will work best for your child then stop into a bike shop to try out the different kinds.
Suspension Options For Kids’ Mountain Bikes
Hardtail or full suspension? This is an age-old question even with adult mountain bike enthusiasts. With children, shocks often become unwanted weight because if the girl is lightweight then the front shock may not even compress. However, well-built mountain bikes take into consideration a child’s lightweight and design the shocks accordingly.
Mountain Bike Brake Options
Old-school coaster brakes let a child slow down or stop by back-pedaling. Many children feel secure with coaster brakes. However, on a mountain bike, coaster brakes create unwanted weight. Some manufacturers even combine coaster brakes with hand brakes. This combo is great if your child wants to transition from the coaster brake system to the handbrake. Once your child becomes confident with the handbrake, you can take the mountain bike to a bike shop and have the heavy caster brake system removed. Remember, most MTBs have disc brakes for increased control and stopping power.

When choosing the best girl’s mountain bike, any of the above choices will work. In my opinion, the Diamondback Girls’ Tess 24 in Mountain Bicycle stands out above the rest.
