Ruedamann 78.7" L × 8.5" W, 600 lbs Capacity, Foldable Aluminum Loading Ramp for ATV UTV, Motorcycle, Truck, Lawn Mower, Snow Blower

Terrific rampLight weight, space efficientFolds in half for easy storage uprightSturdy, support bike weight in/out of houseClever designCost effective

It's a very nice ramp we can use to load our e-bikes into the truck bed! Strong but easy to fold. The anti-skid prevention is effective but not overly abrasive!

I use this to wheel my bike down s short flight of stairs. Makes that task much easier!

They didn't work for what we needed it for we may use them later

Reading the reviews please note that this is not the emery non skid film 4' model so may reviews quote, it's the punched 78" model with the 600 pound rating. Instructions tell you to not exceed a 3.5 ratio of length to rise. That means there might be a problem with a shallow rise. My rise to the trailer bed is only 15" so the ration for me would be a 5.2 ratio. So I have to be careful. The hinge is the issue. So I put wood blocks under the hinge. Suddenly it becomes really, really strong and very stable. Noticing that when you close the ramp there is a large space inside, enough to take a suitable height (for my purpose) hinge support I made from brazed steel tubing sections. When I open the ramp, the support automatically drops down to support the hinge. Just a thought. Get someone to make this for you. Different height, different uses? No problem, just block up to the difference or don't make the internal piece and simply use blocks to support the hinge. Use common sense...as always when setting up a ramp like this. My motorcycle weighs 300 pounds so the ramp was always suitable but supporting the hinge makes it very solid and that's comforting. No flexing, no question. It is rigid and comfortable to use.
