Is the Stark the ultimate freeride / freestyle bike?

Spare parts probably aren’t readily Available. So probably not the best idea if you’re learning new tricks, either way tricks are for kids. 

So the kids riding the bikes look like they are having less fun? Because they didn't have noise?

There is something primal about a noisy vibrating engine you are mastering to move you along.  I am not sure elec bikes can overcome that.  Ktm has had a freeride ebike for many years.  I have yet to lay eyes on one.  The problem with these kind of bikes is you have to have two.  That is all freerides gas or elec.  Then you actually freeride, race with like equipment.  I can see a huge market for playbikes,  but the price has to come way down and i am not sure they can get there.

I lurk around here to reminisce about the days many years ago when my life was moto.  This thing called urbanization was largely responsible for forcing me to quit riding.  If electric bikes came out 15 years sooner I would be racing the +40 class today.  I'm all for electric bikes because I'm the person who was knocked out of the game because of track closures, urbanization and noice ordinances.  To those who talk about E bikes killing moto, I don't agree with you.  Both ICE bikes and E bikes will share the sport together.  Each will have its own niche for the foreseeable future.   

They just need to add a vibrator and speaker and some of you guys will be all over them!

Electric bulldozers are the future. 

I mean, if we can have battery powered hand tools,  RC cars, and even dirt bikes, why would it not also be superior for earthmoving machines? 

It's just pure logic... electric is better for everything.
