How to Turn ANY Bike Into a 72V 4000w MONSTER!!!

I built a 72V, 4000W electric bike using the Kirby kit — and it’s an absolute MONSTER.
This setup uses a 72V 20Ah battery (1,440Wh) ⚡, a 60-amp sine wave controller ⚙️, and a 3kW MTX hub motor, pushing up to 4000W peak speed madness!
Smooth, powerful, and super clean to install — no zip ties or Velcro needed.
