Ours is just about 2 and a bit years old now.
It's reached that stage in life when just about anything causes it to break down and require some money spent on it.
You know the sort of thing, punctures (no end), inner tubes, tyres, ignition switches (lost count of how many), three chargers, brake cables (4, I think) and various other bits and bobs including numerous soldering repairs on wiring faults.
We reached a milestone today, out third battery, this one cost a cool 400 RMB.
I mustn't grumble, we have done around 1000 hours over 2 and a bit years, mostly two up.
And it is convenient. Can't be bad.
