Related Expert Advice articles
Find the right size bike
- Use age as a rough guide but measure the child’s height and inseam (crotch to floor) for a more accurate fit
- Check the brand sizing chart to match measurements to wheel size
- If you can, try out the bike in person
- Choose a bike that fits now, not one to grow into
Four bike types
- Balance bikes: Teach balance and steering for the youngest riders
- Training wheel bikes: Build confidence while learning to ride
- Cruiser bikes: Wide tires for paved paths and neighborhood rides
- Mountain bikes: Designed for trails and rough terrain
Features
- Weight and frame: Lighter bikes (aluminum frames) are easier for kids to handle
- Wider tires: Add stability, traction and cushion
- Brakes: Coaster brakes are easier for younger kids to use; handbrakes appear on larger pedal bikes and require more hand strength.
