Enfitnix Cubelite ii Smart Bicycle Tail Light Review
Enfitnix Cubelite II – Smart Bicycle Tail Light Review

Why I Bought the Enfitnix Cubelite II
I ride long daytime routes around Tokyo, Kanagawa, Enoshima, and Hakone. I never plan to ride at night — but punctures, delays, tunnels, and winter gloom mean it happens anyway.
What I wanted was a rear light I didn’t have to think about. Something that looks after itself and keeps me visible when conditions suddenly change.
Smart Features That Matter
- Automatic on/off – activates when light levels drop
- Tunnel detection – incredibly useful in Japan
- Brake sensing – brightens when slowing down
- Reflective response – adjusts when car headlights hit it
- USB rechargeable – no disposable batteries
Real-World Observations
- Much smaller than expected (approx. 2.5 × 3 cm)
- Extremely bright for its size — don’t stare at it close up
- Metal, water-resistant body feels durable and premium
- One-button operation — no fiddling mid-ride
Mounting Options
It includes two mounting clips:
- Saddle-rail clip (I don’t use this)
- Saddle-post clip (worked, but my saddle bag blocked it)
In the end, I clipped it directly to my saddle bag, which works perfectly and keeps it clearly visible.
In the Box
- Light unit
- Two mounting clips
- Rubber bands and fasteners
- Clear instruction manual
Recommended?
Yes — absolutely.
- Set-and-forget operation
- Excellent brightness
- Great for commuting and long daytime rides
- Perfect for unpredictable conditions
