Thanks so much to Premium Bike Lifts. Their help on the phone and though email was very helpfully. I am very pleased with the service (very speedy and professional). The lift works very well, nice and smooth operation. I have to say that, if your thinking of saving money by not buying the extensions (ATV) think again, you should if only for loading and unloading your bike not to mention a greater work area. Thank you Premium Bike Lifts!
