Investigation in to the non working board yesterday had the board powering on OK, but the remote seemed to be locked.
Screen was on, claiming bluetooth and contact with the board, full batteries.
But it wouldn't respond to any buttons, wouldn't turn off.
Left everything to go flat, see if that would help. Seemed strange if dropping the board would fry the remote.
Emailed support@evolveskateboards explaining the problem, asked if there was any way to re set the remote.
Up this morning, had a reply from Evolve - very impressive - this is just after sales service two years down the track, nothing in it for them.
Went to check the remote - it had powered off. Turned it on, it connected with the board and the wheels spun. Must have just been a disturbance in the force.

Phew.
Remote turned off again as totally flat. Put it on charge in the Kombi as I usually do.
Down to Half Moon Bay after lunch, lovely day for a change, got the board out.

Got the remote, prepared to look for shoes and other recomended equipment that several people noted was missing yesterday.
No power on the remote - wouldn't turn on.
Had a few tries, no go.
I hope the problem is that with lack of use, the car battery hasn't got enough oomph to charge the remote from dead flat.
Back home to put on charge inside.
