I'm pretty certain an electric motorcycle will be at least as dangerous as a gas one.
That just wouldn't cut it.
Part of the motorcycle experience is the visceral feeling you get with the engine rumbling beneath you....the sound, the smells. Also, the connection to the machine with the gear changing, engine braking...clutch, etc.
You feel connected to the road more....
There is a lot of things that make riding an ICE motorcycle enjoyable and a true experience for the rider today....a motorcycle is NOT just about transportation from A to B.
Hell, some days I get up early on Sunday morning before traffic hits (In the New Orleans area...on Sundays you can often have the roads to your till about 11am.
But I'll get up early, gear up and just "ride".....with no set destination in mind. I'll ride familiar roads....I may veer off and explore roads unknown...I just ride.
I saw your reply to someone else and no....adding "speakers" to simulate the sound just isn't going to cut it.
If the only choices I was was an electric "motorcycle"...I'd like not bother anymore...at least half the experience that makes it fun and give one a zen feeling, would be gone.
I think I've got an excellent chance of being able to ride my normal motorcycle till I'm too old to do so...gas isn't likely to disappear in my lifetime, nor will ICE transportation....especially not in the US.
But if it does happen, I do feel sorry for those in the future that can never experience it.
