Its my e scooter which I bought as a replacement for my mobility scooter aka electric wheelchair which I needed after breaking my knee. See my earlier videos which caught the accident on camera. Anyway I found the wheelchair to be too slow 8 mph top speed so I bought this the Zipper X1 and I found that it needs a horn to let ppl know u r there. So I bought not 1 but 2 of the loud arse horns!!! So no excuses for not knowing I was there. Anyways ill be posting the build and demo of the train horns soon so watch this space. Also if you want me to explain anything else please let me and ill get my best to answer any and all questions
