I have purchased and have been using the Cycliq Fly6 CE on my bike since last season and in addition to being great rear light, it also have built in video recording which has proven useful already. Cycliq has sent me an email offering up to 30% discount for cycling clubs depending on how many members actually commit to buying one. They have both front and rear lights with recording and are specifically designed for the cycling community. You can checkout the web link below.
In line with the recommendation by the club executive, if you are interested in purchasing either one or both of these lights, please let me know so we can find out from Cycliq the final discount they would offer.
