Electric Bike Conversion, Ok this is Cool

A good innovation, I wonder what are the good points of an electric bike. Please site some of it.

it's a good idea, but it's not that safe a system... power on the front wheel, especially not pedal assist but independently accelerating wheel can a) drag you into a crash, b) slide your front wheel while steering due to excess power and added weight to front wheel, and c) make it a lot harder to control your balance and drastically reduce the handling of your bike even when not using the motor. i'm not making this up, i work in a sporting goods store and we had several bikes with front wheel pedal assist motors, and even with just pedal assist motors a lot of people took some dives because of the poor handling and added weight on the front. putting it on the back wheel can make a difference, even if it takes those extra (and i'm being generous) 15 minutes to install your own freewheel or cassette on a kit back wheel, or if you really want to switch frequently from standard to electric motor and back again, you can go that extra inch and spend another 20$ on another same cog size freewheel, and then it really would take just 3 minutes each time you wanted to switch. anyway, if put on the back, the bike amd your ride would really be a lot more stable.
