Types of Bikes, Sizes and Features

Contradicting adult bikes, the kids’ bikes are measured by wheel diameter, unlike frame size and seat height. 12, 16, 20, and 24 inches are standard wheel diameters for a kid’s bike

Common BMX types are mentioned below:

1. Balance Bikes

Balance Bikes

(2 To 4 Years Of Age)

These bikes are mainly designed for toddlers and are best for developing independence, confidence and a sense of balance in kids. Gone are the days of tricycles; now is the era of BMXs.

2. Small Wheelers 

(3 To 5 Years Of Age)

The essential first pedal bikes are the small wheelers. What you need to understand is the word essential. The whole bike attribute revolves around the primary category like freewheel hubs, breaks, etc.

3. Middle Wheelers

(4 To 6 Years Of Age)

Kids pick up some actual speed when riding, and that is when middle wheelers prove to be beneficial. They help in developing the required dexterity and coordination for balance, working and steering the hand brakes.

4. 20-Inch Wheel Bikes 

(5 To 9 Years Of Age)

If you plan to go for a 20-inch wheel bike, you and your little one sure have some brainstorming to do considering the riding type. Does your kid want a jumping, racing, off-road or on-road bike? You need to thoroughly check for the size of the bike, your kid’s height and find the perfect fit.

5. BMX Bikes 

(Beyond Age 10 And 20 Inches)

You might hear your kid hoot for BMX bikes with 20-inch realms. Born out of Motocross Motorcycle, these 20-inch BMXs are very popular amongst kids these days

6. 24-Inch Wheel Bikes 

(7 And Up)

Maturity And Ability

So, when it comes to buy best bike brands, how will you assess your kid’s abilities? Only you and no one better than you will understand your child and know how they do when compared to kids of the same age group. This will clearly understand how mature and understanding your kid is and how well your kid can tackle situations.

How good are your child’s coordination skills and ability to ride? You need to just go with that instinct and trust your kid for the starters. You will have to take your kid on the test ride and observe your kid keenly before buying to check how comfortable your child is.

Shopping For BMX Bike For Kids

The first rule of buying a bike for your kid is taking your kid along with you. You will have to make your child sit on the bike to understand the bike’s fit, size, and comfort. Once you and your kid choose the bike, take him/her for a test ride out on the roads. Make further assessments during the actual ride and check how comfortable your kid is while riding.

Fitting The Bike

You have to make your child sit on the bike seat and tell them to grab the handles and put their legs on the pedals. All this is to understand if hands reach the handle quickly and if feet rest on the pedal entirely and not tip-toed.
