Reelight City Combo Front/Rear Lights, Black

Very hard to attach to bikes with rim brakes and I believe dangerous . It requires dismantling and remounting of the brake blocks removing washers and inserting the light bracket to see if you can get both the brake and light to work. I managed this and got the front light and brakes to work successfully for about 6-8 weeks after which time the metal light bracket broke and the light fell off but worse than this the constant movement of the light ( as it is powered by magnetism of wheel movement) loosens the brake block mounting and suddenly my brake block fell off. Maybe I should have been told to constantly check the tightness of my brake block attachments but in my mind these lights are actually dangerous If attached to bikes with rim brakes. 2 bike shops told me this when I showed them my lights. Fine get these lights if you don't have rim brakes and can attach them to the frame but don't try to insert into brake block attachments.

I bought thease lights as backup lights, as they don't need batteries (being a self contained dynamo set).The description for them states the have spoke mounted magnets - which is incorrect.In facts they generate their power entirely from the effect of the rim passing them by (without touching it) - quite clever.They seem to have survived light rain and will generate a steady light even at moderate speeds.When you slow, they will flash until at low speeds the stop giving out light altogether (much like a normal dynamo).It's unfortunate they do not contain a capacitor to give out light when you stop or slow.However the reason for my 3 stars and not 4/5 is the bracket design.The lights are supplied with two types of bracket, one for fitting on your brakes (cantilever or v-brake) and the other type is for fitting to your forks.As I've got disc brakes I used the latter fork mounting type.Unfortunately the brackets attach via zip ties - which allow the lights to move around on your bike.This isn't ideal, as the lights are suppose to stay at a distance of about 3mm from the rim of your wheel and can end up rubbing on it or straying too far.The plastic brackets themselves are also quite flimsy and stick out.Both my brackets have broken through normal wear and tear of using my bike (they don't survive bike racks very well).I've had these lights for about 3 months.

These are a great wee set of lights, that will always work without batteries. No need to attach to rim and add extra restance.Really east to fit and easily to remove for security while leaving bike unattended.These were brought to my attention while visiting a small bike shop in Glasgow called, pronto gara! And they really are great.

The brackets wear out far too quickly, less than six months in my case. Replacements are not available. so if this design fault is not improved their short life span makes them poor value and negates any savings on batteries, not to mention environmental saving.

Nice idea spoiled by poor implementation, especially the brackets that support the light, they need more than one screw to retain the light in position, the magnets in the lamps are so powerful that they'll pull the bracket out of alignment if passed by another steel object.

Easy to fit - but only if you have the right forks. And work well once fitted.They aren't adjustable up and down though, so if your fork frame gets too wide at the top it won't fit. And if you want to keep them fitted permanently you will need to glue them on as otherwise they are too easy to steal (front one lasted less than 2 days in college bike park)
