If you park the bike in your garage on a perfectly smooth surface... it will take a LOT of effort for a child (depends on their age) to mess with the bike and dump it over. The bike is solid on a perfect surface with or without the kickstand mod. Stands might be a good idea for different reasons... but I don't think they are "absolutely" neccessary. Just my opinion. My bike is parked solidly in my garage and no kid under 100 lbs is gonna make it fall over. An adult can come sit on it and it still won't fall. The bike is nearly 500lbs... and no normal kid is going to move it. I wouldn't worry too much unless you've got Dennis the Menace as a son and he starts swinging a baseball bat at the kickstand! If that's the case, I pray for you! haha! But if you've got the extra money, go for a stand. It's safe and effective. I think you'll survive without one... if that's what you're wondering about.
If you're wondering about your children knocking the bike over... they might if they jump around on it like it's a trampoline. If they have any kind of sense at all... they will not. If all 4 of them start pushing on it and try to knock it over... well... they just might make that sapsucker fall! lol! I think it all depends on how well you know your kids.
So. Should you get a stand just because of your kids?
ANSWER: It depends on your kids.
In my opinion, the bike is very solid and sturdy while parked. Yeah, it's heavy.
