All the bike crap you will never use is amazing gifts for the kids on their new bikes you see riding around at the moment.
Great bike, did Father Christmas get you that? Here, have some remote control lights and indicators for it held in place with flimsy elastic bands. No use at all to me but you are 6 and will think they are fantastic*
*possibly worth checking with their responsible adult before just approaching a 6 year old in the park and offering them presents
Also good for work colleagues who get themselves bikes for their New Year ambition to ride everywhere but only need kit that will last a few weeks until they give up.
“Here Martin, have some cycling glove/mitten things for the commute to work. As mittens you have no control of your bike but the ends flip back to expose your fingers which then freeze why you are riding along. No, honestly, keep them.”
