Product Description

Giant solves the problem with its very aero Numen Aero Plus LT rear light. Designed specifically to fit an aero frame the 3 LED's give you up to 6 hours of run time depending on the lighting mode (steady, flashing or patrol).

Mini USB rechargeable means you can charge the rear light at home or at work very easily. The shape of the Numen Aero shell gives the rear light very good sideways visibility which is especially useful for urban riding.

Key Features

  • Aerodynamic design
  • 3 powerful LED’s
  • 3 operating modes: steady, flashing and patrol
  • USB rechargeable (cable included)
  • Flexible O-ring mounts
  • Up to 6 hours run time on a single charge

Looks amazing, works great

So purchased my first TT bike and need a back light for my clubs TT rides. So with a beautiful aero bike and carbon aero seat post this was the obvious choice. It looks amazing and ideal for a TT bike. Not sure it makes any aero difference but looks amazing and works great. Highly recommended

Great Light !!

Excellent Rear Light. Very cool and streamlined on my Giant Propel. USB recharging, looks and lighting modes are as good as anything out there for the money.

They don't fit around my seat post!

I have a Merida and the seat post is too wide for this to fit. I'm guessing that this is only for Giant bikes? I have managed to bodge it but it's not great. Other than that, the light is really good, just a shame that it's so hard to find a light to aero frames!!!

great cheap light

great battery life and very easy to use. Plenty of different modes and attaches to aero post as long as the rear of the post is curved.

Daily commute

Brought this light recently as cycling to and from work now is mostly in the dark and the cheap lights i had wasn't helping to see or be seen. The elastic just fits around my seat post ( i do ride a MTB not a road boat ) the elastic is very stretched and not easy to get on, i hope it holds out. Unfortunately this needs to be undone every time it needs charging( has lasted over two weeks so far - commute is 15min each way). The light its self is ideal and once off the bike easy to recharge with the usb cable it comes with. It has several modes / brightness - I've become fond of the pulsing mode as it seems to stand out more. if it had another way of attaching it id be happier. But a great product non the less.

Great Design

A brilliant solution for the aero seatpost, a compact aero light which complements the smooth lines of any bike. Highly visible and easy to fit and remove. Delighted with this purchase.

Giant Numen Aero Light

Bought this for my Ridley Noah RS which has an aero seat post. Light looks really well on bike. Fits well only the rubber band is quite stretched so hope it doesn't break. Band is stretched as my seat post is larger than Giants. So would not be an issue with a Giant bike. Excellent light for the money a bargain!

Rear Lights Buying Guide

 

Rear Lights Buying Guide

While front lights can reach up to and above 1000 Lumens, at the rear anything from 20 to 100 lumens is plenty. Multiple rear lights are the best way to be seen from behind, especially when on the flash mode.

With one attached to the seatpost it can be good to have another on the chainstay, backpack or helmet. 20 Lumen would be sufficient for commuting in urban areas. For those living in darker areas or riding on dimly lit roads, a rear light closer to 100 lumens would be best.

Take a look at our Rear light comparison tool to help you choose the right bike light for your needs.


Wearable lights

Extra visibility

If you commute on lit-up city streets, rear lights are more than essential. To have a second light high up and in the eye-line of drivers and other road users is a very good idea. With reflective clothing and/or accessories like backpack covers and jackets, adding a wearable rear light will really make you stand out. Most backpacks will have a loop or somewhere to secure a light, using the strap or mount that come with the light.

Usually not a concern for MTB riders, nothing extravagant is needed for the rear, just so the rider can be seen on any road or path that might lead to the trail.
