I bought this ball horn in 2011 in Bangalore (India) and when I returned to Germany half a year later, my mother liked it so much that I gifted it to her. I always wanted to make a bicycle mount, so she could roam the streets with it and now the day has come!
The space between handle bar and basket is narrow, the handle bar itself is curved and has a non-elliptical cross-section and the horn naturally isn’t a straight pipe either. In short: it was challenging, but worth it!
I figured my mother would be happy about a possibility to quickly attach and detach the horn sometimes without tools, so I added this feature
