[h=2]REVIEW: CB SEEN City Slicker Twin LED 500 Lumen, Rear Bike Light[/h] This is part of a combo set of the City Slicker which has been sent to me for review by C&B SEEN, a small UK company based in Kent.
Please note that despite the fact that this light was not purchased by myself, my review is done under the same format as the one I purchased.
In my reviews, I try to expose the light's weaknesses and strengths while being fair to its specs. There is no comparison to other products unless stated.
My reviews are done with other riders in mind who may be thinking of purchasing the same light.
The lights I review are not always a reflection of what I prefer or ride with. All I am doing is trying to give you an unbiased opinion of the product I have tried/reviewed here in the UK.
What's in the box
The City Slicker 500lm rear light is supplied in a blue display box with a viewing window to see the product.
The packaging is identical to the one used on the City Slicker front light which I have just reviewed.
They have now improved their user manual which comes in a neat tri-folded coloured instruction booklet.
Inside the box is the lamp unit with a pre-attached quick release clamp, a micro USB lead and rubber spacers for the clamp.
Initial overview and feel*
The City Slicker rear bike light takes the form of a short twin barrelled light, with a big window showing the two LED. The light feels sturdy as it is made of anodized aluminum and has side cut outs for rear and side illumination.
The USB port is on the back panel and is protected by a rubber grommet. The light, like the front one, is charcoal black with white etching for their logo and name.
The optic/lens appears to be made of plastic and are held in place by two hexagonal screws.
The body is plain with shallow groves in the centre and all angles are rounded.*
The switch has a built in battery warning light using the well established traffic light method green, orange and red.
The battery is accessible via the removal of the two rear Hex bolts and panel. My bike 2mm Hex tool fitted the bolts . For longer rides you can carry a spare battery if required.
The light's fixing clamp looks and feels sturdy and used the o ring method to attach the slicker to the seat post
Manufacturers Data (latest)
With regard to the materials used on the City Slicker, not a lot of data is shown on the C&B SEEN website or is given in their instruction manual.
The body appears to be made of anodized aluminum with the optic/lens made of plastic.
The light is waterproof to IP65 standards (to be confirmed).
The battery used is CB SEEN own labeled CR123A rechargeable /16340 3.7v 800mAh.
On their web sites the LEDs are advertised as XM-L L2
On the instruction manual, no reference is made to the LED used but I believe them to be the Cree XLamp XB-D 2.5x2.5mm Red color LEDs on my sample.
Settings
The light has 4 modes - Economy, Pulse, High, Low.
To switch the light on hold the button down for 2 seconds. The light will come on initially in Economy which is a flash mode. Single clicks will then cycle the light through Pulse another flashing mode and then to the two steady modes. They are no indications of the output of the steady modes, but I think it would be fair to assume that the high is their 500 advertised lumens.
Hold button down for 2 seconds to turn light off.

*Like all rear lights it is always difficult to see how good they are unless you are behind! When I pass a cyclist on the road, I always check how visible their lights are and try to spot what make they are.
The main problem with rear lights is that cyclists often neglect them riding with rear lights glowing faintly. In my mind they are as important, if not more, than the front one. They cover your back where you cannot see!*
So you need them to be bright. With the City Slicker rear, this will be easy as it is USB rechargeable, and if you have not got a computer or a phone charger available, you can swap the battery.
I know regulations are a little different worldwide, but I would advise any cyclist here in the UK to have two rear lights one in steady mode and another in flash mode.
The City Slicker has been tried during my commute at night. The City Slicker rear has a massive advertised output of 500 lumens which is very bright.
Regarding the mounting instruction supplied, I believe them not to be 100% relevant to the rear light as they talk about adjusting the angle of the clamp on the bar to avoid dazzling oncoming drivers.
Regarding the mounting of the light on your seat post there is NO vertical angle adjustment. You can fit the light as far up or down as you want on your seat post but the angle of the light is determined by your seat post angle.*
This is not a bad thing as it will prevent cyclists having them pointing directly at the following traffic. This implies to me that the light works in a different way and when you see it in action, it does, The Slicker rear produce a bright light visible a long way away but also created a red halo behind you rear wheel. For those like me who have a mud guard you will find that the very bright light bouncing off it creates the impression of a secondary light effect, (see my photos).
As mentioned earlier, you can swap the battery for a replacement one if you find yourself away from a computer or a mobile phone charger when the battery is running low. A 2mm Hexagonal tool will be required. I would recommend extreme caution while doing this on the side of the road because if the small screws were dropped you would have trouble finding them! Do look at which way the battery is fitted as there is no indication of polarity, I would strongly advise the user to mark the positive side.
Trying to replicate what the eye sees at night via photos is not easy, so to help with your perception of the light performance here are the setting used during the beam shots.*

Very bright creating a red halo on the road behind you
Side windows
Good run time
Easy interface

I believe that for the moment they are only retailed in the UK.
