I looked at the Buddy 150, and I like it a lot, but in my market it costs a bit more and I'm told it is slightly less robustly made than the People 150. I assumed such talk was unreliable but I heard it pretty uniformly. Most people do say it's quite zippy though, but part of the reason why is the smaller diameter wheels. Especially with some weight on the bike, I like to have the big gyros. I can go sub-3mph indefinitely in traffic, which is nice, 'cause Cagers don't know that riding slow is hard. Cagers don't know a lot of things... Now the motorcycle has 17" wheels and heavier tires, but weighs about 200lb more, so slow-and-go traffic is a real drag on it. I say test ride them both. Be sure to try riding both at very low speed, too though. As slow as you can without falling, and see if there's a difference. Those smaller wheels in the Buddy will spin up faster, but big wheels are better at low and high speed, in my opinion. From 15-35 there's not much difference, but below 10 and above 40, 16" wheels are better for me.
Now tire selection is another story, and mostly a sad one for 16" tires, but I like my new Heidenau tires. A lot. I'm actually getting more excited about riding my scooter fast since putting them on than makes any sense. My only complaint, and this is more about urban scootering in general than about these tires, or any tire or tire size, is that many of my trips in the scooter barely warm the tire up. I usually give a super hard front brake stop and go by sound to determine if the tires are warm, and it seems to take about 2/3 of the trip to most of the places I go before they're hot. I'm not gonna buy or use tire warmers for around town.
If you're gonna look at the Buddy 150,give the Super 9 (or Super 8 ) 150 a look to. It's a similar platform, though styled differently. I can't speak for styling much. More into function than form.
I do really like the long mirror stalks on the Buddy. Again, function. It's a good lookin' scoot, though.
