My epiphany moment was when I was cycle commuting in Portsmouth, along dark and busy country lanes.
My Chinese torch (on the bars) required frequent ‘whacking’ to make it work. It would just flicker on/off when it felt like it.
I had visions of me flying through the air in slow motion, bike and bonnet crumpling below me, whilst I gurned and shook my fist screaming “damn you £20 Chinese light…damn you…”!!!
It’s odd, but with a joystick or maxx d on the bars, and a wired red eye on the back, I felt a LOT safer.
Worth the financial outlay just for that.
