Harley Rental Portland Oregon
The bike rental company that we work with here at BikeRentalsUSA is one of the best in the world. They have a great reputation for customer service and they offer some of the lowest prices around. If you need a new bike for a day or two, they are definitely worth checking out. They have bikes ranging from $30-60 per day depending on what type of bike you want. The main difference between their different types of bikes is how much gas mileage they get. Their Sportster gets about 30 miles per gallon while their Road King gets closer to 50 mpg. Either way, these bikes are perfect for short trips because they don't take up a lot of space and they aren't very expensive.
They also offer a few extras like helmets, locks, maps, etc. All of their bikes come with insurance, but they only cover accidents caused by them. So make sure you wear a helmet, lock your bike, and keep an eye on where you park it. Also, make sure you read through their terms and conditions before renting a bike.
