Just installed these 120mm stainless steel brake rotors on my Niu Max scooter, and wow—what a difference! The heat dissipation is no joke. Did a long downhill test, and no scary red-hot discs here. Safety upgrade? Check.

The floating design is clever—keeps things stable even under stress. No weird wobbles (unlike some reviews mentioned). Maybe they got a lemon? Mine runs smooth as butter after wiping with alcohol before mounting.

Pro tip: You CAN replace the rear without disassembling everything if you’re careful. Saved me 30+ screws worth of headache! Fit like OEM on my buddy’s GoTrax too.

Only gripe? Packaging could be sturdier. But for this price and performance? Absolute steal. If yours arrives bent (looking at you, kid-damaged-rotor reviewer), just email them—their customer service responds fast!
