Make the small bike feel properly planted.

The Projekt46 Big Wheel Kit upgrades smaller 12"/14" bikes to a balanced 14"/17" MX setup—the same general wheel sizing used on larger premium mini e-motos.

Why It Matters

Larger wheels track more confidently through rough ground, add stability at speed, and improve comfort without making the bike feel as tall or specialized as a full 16"/19" conversion.

What’s Included

  • 17" front wheel and tire
  • 14" rear wheel and tire
  • Front brake rotor
  • Rear brake rotor
  • Rear sprocket

Fitment

Intended for supported Qronge Spark M/L, LeonX Amp/Max Amp, and Lifemagic M9/M9 Pro applications. Select the option matching your factory 12 mm or 15 mm axle setup. Confirm axle, spacer, rotor, sprocket, chain, swingarm, and frame clearance before ordering.

Before You Order

This is an oversize shipment and additional shipping charges may apply. Changing wheel size can alter ride height, gearing, speedometer accuracy, chain length, and handling. Professional installation is recommended.
