I'd assumed the bike would monitor battery voltage and only engage the system if the battery had sufficient charge to fire the bike up again at the lights.
On the way to work this morning, my bike went to start up and then immediately stalled. It wouldn't restart then and I had to walk the bike to a local garage to get a jump start.

I ran the bike for around 10 minutes which I'm hoping will provide enough charge for me to start it up again in a few hours!
Has this happened to you?
