Better and easier you can not increase the security of your own bicycle at dusk or in the dark.
Simply click the reflectors in the spokes (36 pieces ranging from a front or rear wheel to be fitted), and even illuminate the wheels of the bike right light by reflecting the incident light of the car or other vehicles.
We have now fitted the bikes for the whole family with this spoke reflectors, especially in winter when the kids go to the wheels in the dark to school this increases safety tremendously.
It is recommended that the reflectors about once per year to clean, this one takes them off easily and washed with warm mild soapy water clean again, then they shine like new again.
The reflectors keep very, very good on the bike, it's never happened before in all the years that my husband has lost one.
All in all, a thoughtful and meaningful thing, so an unqualified Recommended and earned five stars.
