If your battery is flat, can I bump start my Bike?

I've coasted down the hill in front of the house, and caught it in 2nd gear a few times. I have seen on one of the internet boards that a few folks have said that you should try to catch it in 3rd gear, 2nd worked for me.

Depends up on how flat. There has to be at least a little juice to get the electronic brain to wake up. If the battery is completely flat, bumping won't work. If you haven't ordered a new battery yet, you should do so now. Good luck!

1st and 2nd gear have worked for me, depending on how flat is the battery, usually happens when I haven't used the bike for a long time, so the bat is JUST DOWN, NOT DEAD, and after riding a while it charges back (it's better if you ride at least 40 or 50 miles to charge it)... if it still doesn't charge after riding get a new one...
