Balance bikes can teach a kid to ride a bike better than training wheels can. To ensure your kids have the comfiest ride ever check out the ZumZum. It has a wooden frame designed to provide a cushion for rider for all day comfort. There's an NFC tag built into the wooden steering wheel in case you want to check the owner information and warranty. The tyres are non-marking so don’t worry about using it indoors.
$149 – This was successfully funded on Kickstarter but the creators did not deliver on their promises like many other Kickstarter creators.
