Nice and Bright

  • Familiarity: I've put it through the wringer

I've used it for about a year, riding for about 1,000 miles. The solas performs well, it's very bright so it can be seen far away. After one year, the battery still charges well and lasts per specification. The only complain I have is the on/off/mode switch, it is not that easy to switch from one mode to another. Otherwise, everything is great.

Died after 3-4 months

  • Familiarity: I've used it several times

I bought this because I thought this more expensive light would be more reliable and have longer battery life than the cheap $15 variety.

Weak battery life

  • Familiarity: I've used it once or twice and have initial impressions

Very nice light, bright and flashes prominently. Unfortunately, using either flash mode the best length was 3 hours then the battery dies. Not acceptable. They quote 4.5 and 6.5 hours. Not in my case. Returning for a different type of light.


  • Familiarity: I've used it several times

The actual light part of it works as advertised. But it has lots of issues. It doesn't stay in position very well, sometimes it will shift and I'll find at the end of my ride it's now pointing down. Not too helpful to have a rear light facing down. The rubber cover over the charging port is difficult to put back in so I'm never sure if it's covering it and preventing water from getting in. There doesn't seem to be anything in the manual about the charging light indicator. Sometimes I plug it in and there's no light so I'm not sure if it's charging or not. Sometimes after a few hours the light will turn bright red. Then after that it will turn blue. I think that means it's fully charged. But not sure. All in all I wouldn't buy it again.

Bright but not waterproof

  • Familiarity: I've put it through the wringer

I used this light for most of this winter, mostly with fenders, but I recently took it out on a road ride with a lot of spray from melting snow. Afterward, it turned on but never worked quite right again - the flashing modes were all wonky and it became difficult to turn off. The placement of the USB charging port at the bottom of the light, directly above the rear wheel, seems like a bad idea.

HI Matthew, thanks for your review. Niterider's pretty solid in the warranty department, so get in touch with us and we can work with you on a replacement.
