The Kids Ride Shotgun Dirt Hero 12" Wheel Kit is the smaller of the two wheel options for the Dirt Hero balance bike, designed for younger or smaller children typically aged 18 months to 3 years. The kit includes a complete front and rear wheel set built around Vee Tire Co Crown Gem 2.25" off-road tyres — a knobby, pneumatic tyre designed for dirt trails, providing grip and traction on loose and uneven surfaces. The wheels are built with 2mm stainless steel spokes in a 16x radial lacing pattern for strength and durability. Custom KRS through axles are included for both front (100mm) and rear hubs. Dropout adapters are included to ensure a correct fit in the Dirt Hero frame dropouts. Note: the 12" wheel kit does not include a disc brake mount — if you want rear brake capability, the 14" Wheel Kit includes a disc brake mount and is compatible with the optional Magura Rear Brake Kit.
The 12" wheel kit is the right starting point for younger children building their first Dirt Hero, keeping the bike low and manageable for smaller riders. As your child grows, the frame can be upgraded to the 14" Wheel Kit. Replacement tyres are available separately — see the Dirt Hero 12" Tyre. To build a complete Dirt Hero, you will also need the Frame Kit, Saddle, Grips, Foot Platforms, and Headset. Browse our full Kids Ride Shotgun range.
What is the difference between the 12" and 14" Wheel Kit?
The 12" kit suits younger or smaller children (typically 18 months to 3 years) and does not include a disc brake mount. The 14" kit suits older or taller children (typically 3–5 years) and includes a disc brake mount on the rear hub, making it compatible with the optional Magura rear brake. If your child is between sizes or growing quickly, the 14" is generally the better long-term choice.
Can I upgrade from 12" to 14" wheels later?
Yes — the Dirt Hero frame is compatible with both wheel sizes. When your child grows into the 14" size, you can purchase the 14" Wheel Kit separately and swap the wheels over, keeping the same frame.
What tyres are included and can I replace them?
The kit includes Vee Tire Co Crown Gem 2.25" pneumatic off-road tyres. Replacement tyres are available separately as the Dirt Hero 12" Tyre.
What else do I need to complete the Dirt Hero build?
In addition to this wheel kit you will need the Dirt Hero Frame Kit, Saddle, Grips, Foot Platforms, and Headset. All components are available in our Kids Ride Shotgun range.
