hi and welcome to the forum. i have a 70cc chineese and use it to go back and forth to work which is a little less then 10 miles. i cruise at around 29 at been getting around 130-140 mph. cost wise i have paid for it many times with the gas i save not putting it in my truck. during summer months i go from filling up twice a week to 1 time every 2 weeks. short trips with a vehicle gives you the worst gas mileage up to 30% less on it. motorized bicycles are great fun and a great way to save on gas. glad to have you with us
