Solving heavy monster bikes with electrical power is self defeating.
Of course the hardcore enthusiasts will need something tougher for offroad or similar applications but keeping some focus on the bike will create years of enjoyment and adaptability.
That is pretty much what I did above, but that is a rarity for a build. Light and fast isn't very popular. I supply about 1/2 the power, the motor (which is very small) the other half. It does 25mph for 25 miles at 25lbs. :-) That doesn't include the weight of the 3.75lb battery though.
