Segway Ramp Kit
The Segway i2 weighs in at a rather hefty 105 pounds. Lifting all that weight by yourself into the back of your car is just asking for trouble. I mean, come on, it's not like it's a set of barbells and most car trunks require considerable maneuvering and gymnastics to get over bumpers and whatnot.
Segway's solution is a very nice set of ramps; well constructed with a lip at the top that hangs on the the lip of your trunk. On my car, it works out great as the ramp never touches the paint of the car. Obviously, your milage may vary.
Tthe documentation that comes with the ramp kit states loading the Segway into the car is still a two person job and should never be done while the device is under power. Ok, clearly the advise from Segway comes from their legal department, but come on, that's what I got the ramps for! So I could load the thing by myself and not have to use a whole lot of muscle to do it.
One small bit of advice in using them. If you have a small tape measure, you'll notice the distance from centerline to center line of each wheel is a certain distance. When setting up the ramps, take the tape measure and make sure both the top and bottom of the ramps centers are also spaced apart this same distance.
I would not advise trying to ride up the ramps, but if the ramps are spaced properly, I find it's pretty easy to load the device while it is in Riderless Balance Mode.
And they work pretty darn well, are ruggedly constructed and nicely finished.
About the only bad thing I have to say is that they do seem a bit expensive for the function.
