i created this instructable because i have seen some other really good bike mounts but i didn't have the some materials or they wouldn't have fitted my bike (i have a vintage bike). it is designed to sit on the handlebars rather than the neck of the bike as the neck of my bike isn't shaped properly for that sort of thing but could be changed to do the reverse.
for this mount you will need:
- an old reflector
- a hard case for your phone
- various screwdrivers
- pliers (maybe)
- hot glue gun (and a surface protector such as newspaper if you are working inside like i am)
- possibly a piece if rubber if the handle bars are narrower than the reflector
