If you can spend $349 instead of $249, the Hiboy DK1 is the better kids electric dirt bike. The lithium battery and disc brakes alone justify the extra $100.
Hiboy entered the electric dirt bike market with the DK1 and immediately stood out. At only $100 more than the MX350, it brings a lithium battery, 500W brushless motor, and disc brakes — meaningful upgrades that justify the price difference.
The 500W brushless motor outperforms the MX350, reaching 15.5 mph with stronger hill-climbing. Disc brakes provide better stopping power. For riders aged 8-12, this hits the sweet spot of performance and safety.
The 36V 7.5Ah lithium battery is a significant upgrade. Lithium packs are lighter, charge faster (4-5 hours), and maintain consistent power until depleted. The DK1 delivers about 45 minutes — 50% more than the Razor MX350.
