We went last Tues. to Fredericksburg Tx. and Luckenbach Tx. about 750mi. just three day getaway , bike pulls trailer great, FUEL MILEAGE NOT, pulling 70mph. 27mpg, I would have expected better.It now has about 2000mi. I am sure not broken yet still seems tight , power good on interstate, you can pass anytime with trailer at will, taking off a little more bottom end would help, but rolling power is more than adequate, I was surprised, Just have to live with mpg. wife likes it so much better than the Trikes she has had , only problem is you get stopped everywhere to inquire about it, make sure you are boned up on specs.
