Q1: What seat post sizes does the Vmax+ 180 fit?
The Vmax+ 180 fits seat post diameters from 15.8mm to 31.6mm, covering most road, commuter, and gravel bikes (27.2mm is the most common size). It also attaches to bags or clothing using the integrated clip.

Q2: Is the Vmax+ 180 compatible with my bike setup?
Yes — the included rubber mount works on standard round seat posts, and the clothing clip lets you wear it on a bag, jacket, or backpack strap if your seat post shape doesn't suit a clamp mount. Our staff can help you confirm fit before you buy.

Q3: Can I run the Vmax+ 180 alongside other lights or accessories on my bike?
Yes — it's a standalone rear light and won't interfere with front lights, computers, or other accessories. If you're pairing it with another NiteRider light or an existing mount, our team can confirm compatibility in-store.
