I have three Ice Bear 150 scooters (GY6). The first one has over 8000 km on it with no issues and the other two haven't been used much. One is in the mountains of WNC and the other was my ride on Sanibel Island at our cottage there and luckily it wasn't there when hurricane Ian destroyed the cottage. I think I will leave it out at the ranch 30 miles east of Fort Myers, FL. They are very good to ride around town but top out at 55 or 60 MPH which is fine for me. They are very simple to ride and maintain. The first one I bought is a 2000 which cost $1,000 delivered to my house. The other two are newer and I think the price now is about $1400 or so for the same scooters.
I think they are decent quality and don't make the mistake of trying to soup them up. If you want a faster scooter buy one with more ccs.
The small bike in the photo is a DF250RTG which is a fun ride.
