The vacuum can mount on metal or glass surfaces and even fiber glasses and hold bikes of up to 45 lbs.

I drove my bike into the top of the garage door once and ripped it off when I forgot about having a bike up on top of my car. Never again." Rough sections of the dirt road caused no loss of suction. Plus, this second round of mounting the carrier and attaching the bicycle took 2 minutes — and I wasn’t at all rushing. Let me just elaborate a little bit. When you press a suction cup against your car’s surface, you push out the air inside it. It eliminates the pressure inside the suction cup and creates a vacuum. This vacuum seals the cup tightly and firmly holds on to the surface.Safer: This system has an air pressure sensor, which will automatically re-inhale when the pressure is lost. And equipped with a pressure sensing device, which can detect the air pressure in the car in real time and deal with abnormal conditions at any time. some cars have sleek lines and get difficult to attach the suctions cups properly- they do not always get tight enough on some newer vehicles which can be frustrating if you want it secure. The best part about this carrier is that it has no metal parts or screws. This makes it safe for paint jobs because nothing will scratch your vehicle’s finish as you travel around town.

This thing will tell you if you need to re-pump again. SUCTION: Don’t worry about the vacuum loose, the 8” suction cup has powerful suction that can hold up to 48 hours if fully sealed. The red-Line Indicator warns user of any vacuum loss. When it shows less than 100% vacuum left, simply pump the plunger until you reach the original vacuum pressure without removing the cup. Now, you may ask, wouldn’t the cup slide? As a matter of fact, no. the cup doesn’t slide because the friction created by both the cup and surface keeps it from sliding. But to work like this, you have to take care of few things first. Don’t get disheartened. They’re not tedious at all.
