Electric bikes are;
-Cheaper to run
-Faster
-Instant power/No lag
-Reliable - less moving parts
-Could potentially be lighter in the future
-Solar panels which can re-charge your bike, imagine having an electric bike in the middle of a desert with solar panels on.
But...
-They're expensive... very expensive
-Not a lot of stations at which you could re-charge, btw they're building one 1 mile away from me

-Full charge on LS-218 takes 30min, long charging times which will probably improve in the future
-Range 100-200miles on LS-218, again this will most likely improve in the future.
-No option of having an after-market exhaust system

The solution could be speakers, but they will not fully replicate a nice exhaust sound.
-No gears - A lot will moan, but I personally prefer having all that power at any time I want.
What do you people think of H2 to be used as fuel? With our current technology I personally think that electricity is better, but this can change in the future.
