Projekt46 Big Wheel Kit (14/17 MX)

Ditch the dinky 12 inch and 14 inch factory wheels with this kit! 

The 14/17 Big Wheel Kit is the stock wheel setup found on larger models like the Qronge Spark L, Leonx Max Amp, and Lifemagic M9 Pro—and for good reason. It offers a great balance of stability, comfort, traction, and handling without making the bike feel oversized.

For riders with a Qronge Spark M, Leonx Amp, Lifemagic M9, or similar platform, this kit is one of the most practical upgrades you can make. The larger wheels help the bike track better through rough terrain, improve confidence at speed, and create a more planted riding experience overall.

The result is a bike that feels more mature, more capable, and better suited for both trail riding and daily cruising.

Why We Carry It
Not every rider needs a full 16/19 motocross conversion.

For many riders, the 14/17 setup is the sweet spot. You get the benefits of larger wheels without dramatically changing the bike's seat height, geometry, or character.

We've ridden enough of these bikes to know that wheel size makes a huge difference. The 14/17 setup helps smooth out rough terrain, improves stability, and gives the bike a more substantial feel while keeping the nimble handling that makes lightweight e-motos so much fun.

It's one of those upgrades that simply makes the bike feel "right."
