Nice bike! No you did not get ripped off. It's a decent price for that bike. You even have some budget left over for some accessories. Well done!
For starter accessories I would recommend:
- helmet
- Front Blinker Light
- Rear Blinker Light
- Rear Rack with some type of storage
- Chain Lube
- Chain Degreaser
- Basic multi-tool (or individual tools)
