I agree I think the recharge time is in question. I guess if I could get a quick change battery system and battery recharge docking type station, that would work ok... guess you can't have your cake and eat it too.

I would want. (not in order of priority)
1) clutch (or something that created the same affect/feel)
2) Great build quality
3) recharge quick (would love 15 min to at least 80%, but 30 to 80% would do)
4) competitive rebuild costs and intervals,
5) 2.75/21 and 4.00/18 tires
6) light weight
For reference, a quick charger on a Nissan Leaf is pumping about 100 Amps at 400V. That's a little more then what the home chargers run.
Yes, a bike would be a smaller battery pack, but watts are watts. You would still need to bring a pretty big generator to keep in the pits if you wanted that kind of charge rate. Now how much is that generator going to run you? Not many places out in the woods to find a good 50A 240V outlet unless you bring it with you.

I was thinking more for riding around the yard and neighborhood and then recharging, as for trials event I would just bring extra fully charged batteries if I was going to do an E-Bike.

I can't believe Oset does not make a "grown up" full sized version! Anyone who rides is just a kid at heart?

I'd love an elec. trials bike. I'd also, I think, want a clutch and flywheel. Definitely want standard trials bike components for suspension, wheels and tires. Battery needs to be able to complete the longest loops around at least once and should be able to be swapped for a charged on really quickly and easily. I would imagine that I'd do a loop, swing by the truck, swap batteries, do another while that one charges back up, and so-on.

1000 cycle rating on a battery that lasts "50 - 150 minutes" is the real problem for me.

It's the problem for everybody really. If there was a battery that lasted all day before needing a charge and would last for 10,000 cycles we would probably all have one already

The riding season in Alaska is pretty short. The ability to ride indoors would stretch the season immeasurably (or at least six additional months).

That alone would make an electric trials bike very attractive to me, despite the obvious battery limitations. If riding indoors in the winter worked for the Smages then it might have a broader application for the rest of us. You could ride and lose only a fraction of the brain cells lost from riding a gas bike indoors.

The 16" Oset that my kids have been beating to death makes me truly jealous. It's easy to ride, requires no maintenance and if it didn't weigh as much as a tank, would make me buy a 20" immediately.

I hope that Kuberg works out and comes in at a realistic price point.

The OSET 20 is 20Kg lighter than any of the conventional bikes, so I dont follow you about the weight.

It's comparatively a tank when running the lead/acid batteries.

Compared to what? Any gas bike I know of in that class is heavier. If you mean that you should ditch the lead acids, then I can see your point, but big $$ on a kids bike.

Yup, definitely not cheap. But on the 20" OSETs going with EarthX batteries cut more than 10 lbs. from a bike already weighing less than 100.

Would like to know if these electric powered trials bikes need to be registered (green sticker I would think in California) to be able to ride in an OHV park? Or is this a gray area and they are considered somewhat as a toy?

I can't answer the question for California. For New Mexico, if the vehicle does not have a 17-digit federal VIN titling and registration is nearly impossible. The 20-inch OSETs lack a VIN. I understand the new Kubergs will have VINs.

For now the kid-sized electrics are ignored and placed in the same class as a Barbie Jeep.

I don't know why I am so fascinated by electric trials bikes, I can't even ride the gas one I have very well, but did you all see this?

A good friend will take you trail riding, an ADV friend will double back and say, "how did you get down there?"
