I have 3 "bicycles"
1 serious old school classic
1 mountain
1 cruiser

then I have 1 electric bicycle
1 very serious all weather all terrain electric bicycle
1 electric motorcycle
and a gas powered.

I am thinking of taking a spare gas kit I have and putting it on the electric bicycle I have so I have a the option of either.

Frankly...where I live...it isn't an option whether to have a regular bicycle to get around or not.
Between :
1- The hills out here,
2- the inclement weather at times,
3- the distances for daily commuting,
4- the cost of daily ferry travel
5- the ferry delays and inconsistent times when the ferry can show...

All make the electric bicycle alternative a "must have" here.
