You have to think about your son and your child’s riding style and which features are more important to him and to you.


  • Balance bikes will have a lower stand over height and will have a good coaster brake so your early rider can just coast down hills at fast speeds with its fast rolling tires and still brake safely. Mountain bikes have good brakes and better front suspension fork systems than other bikes for rolling over bumps in the light trail. You can also have a cruiser bike that’s good for riding on paved roads and sidewalks.


  • There are different types of brakes. You can get kids’ bikes with V-brakes, U-brakes, a coaster brake, or mechanical disc brakes. Most 20-inch bikes won’t have the mechanical disc brakes built into them. It’s easier for children to brake more slowly and safely with other types of brakes. Also, mechanical disc brakes usually make kids’ bikes cost a bit more, unlike hydraulic disc brakes.

Multi Or Single Speed

  • 20-inch bikes often come in multi-speed options. There will be different gears and some sort of gear shifter, either a lever or a twist grip shifter to change the speeds. It makes it easier for kids to pedal up hills or across rough terrain. For many kids, the twist grip shifter may be easier to use. If your son is going to be getting his first multi-speed bike, look for one with a twist grip shifter.
