Points to Consider When Choosing a Dirk Bike for Your Kid

Building champions for dirt bike competition can start early, during the childhood of the champ. If you are going to introduce kids to this thrilling and adventurous sport, starting with toys that look like the real bikes can prepare them before they become big enough to handle the real dirt bikes. E-bikes are now a very popular alternative to gas-powered bikes for kids.  

The first types of dirt bikes were made up of bulky SLA batteries and less reliable engines, which increased the bike’s weight and made it less efficient. Due to progress in technology, however, e-bikes are now a force to be reckoned with in the world of biking.  More manufacturers like Yamaha and a host of others have picked interest in the electric bike market; some bikes even deliver better performance than their gasoline bikes counterparts. Razor is currently one of the leading electric bike manufacturers, and the MX series has become very popular. Their bikes are pocket-friendly, durable, and safe.  When deciding on the electric dirt bike to get for your kids, keep the following in mind:

Age Range

Different dirt e-bikes are designed for various age groups.  You have to take care that your child falls within the recommended age prescribed by the manufacturer before picking a particular model. Although many manufacturers usually overestimate the age group, like in the case of MX350, they recommended it for children aged 13 and above. Meanwhile, the bike is most suitable for 5-10 years olds. You need to assess your child’s maturity and skill level to see if they can handle the model you are about to buy.  Allow the child to ride in it before paying. 


The capacity of the battery and its durability should also inform your purchase decision. If the battery of the bike model can’t hold on to charge for a long time, it means your child will have to stop on the road and carry the bike often after the battery goes flat. Battery life tells you how efficient your trip is and how much money you end up spending to charge it. Buy a bike battery that is produced by the same bike maker if possible.  

Technical Specs

Manufacturers usually give a maximum passenger weight like in the case of MX350 and MX400, and the maximum capacity is 140 lb.  Nothing the size and weight of your kid are essential in determining whether or not the bike will be suitable. Also, the material from which the bike is made to determine if it will be durable. Most dirt bikes make use of steel. Also, ensure that the designs on the bike are colorful and appealing because kids love colorful stuff.

For performance, check how fast the bike can run.  A Moderate speed is what we recommend for children as they get an adrenaline rush even when they are still safe. The pace at which the bike runs should perfectly complement your child’s motor skills.  Finally, assembling the model you buy should be easy to put together.  Most bikes are packaged semi-assembled by their manufacturer. Assembling the bike yourself will help you know it better if you need to troubleshoot a fault later.


E-bikes may have a parking switch or brake.  You should make sure that the system is responsive and easy to access by your kid.  Find out if the bike has variable speed settings or custom speeds, as is the case with the MX400 or MX350.

Value for Your money

This is an essential point to take note of since your children will soon outgrow the toy bike. You shouldn’t spend too much on gadgets that they will no longer use after a few years. The features of the MX350 and MX400 are practically the same. Explore the features of different models and manufacturers to choose the most economical option.  The MX350 is a bit cheaper that the MX400, so you’ll save a few bucks by going for it.

Wrapping Up

Thanks to continual improvement in technology, dirt bikes are now safer than before. Getting a dirt bike for your kid is a right way of positioning them for an adventurous life of dirt bike sporting and positioning the child as a future champion. A toy electric dirt bike running at a maximum speed of 14mph and a safety helmet is a good way to build the love of the sport into your kid. Razor e-bikes are great, and there is very little difference between the MX350 and MX400 based on personal assessment.
