Question: What exactly does 'wheelbase' mean?  From the point of contact with the ground between the 2 wheels?
Document: Actually it exceeded our expectations. The directions for assembly were very good and the unit went together with no problem. Our trike and bike fit perfect and ride smoothly to our destination. We love it. Also we appreciated that the item arrived in two days (this was not 2 day guaranteed) as we were going out of the town. Everything was perfect!
There are three possible configurations - (1) two bikes; (2) one trike; or (3) one trike and one bike. Because I bought it specifically for ma trike, my choices were either 2 or 3.The first thing to know is that configured in 2 or 3 the &#34;wings&#34; do not fold to the center for storage.
Very sturdy and holds the bikes solidly. Very adjustable to fit just about any bike.Does everything I was hoping for in a bike rack for the car.
This is one very well engineered bike and trike rack. It's a little heavy, but very sturdy, easy to install on the vehicle, a snap to mount the bikes, folds up when not in use, folds down to allow access to the rear hatch of our Toyota Matrix. So far there's not a single dislike or wish something was designed differently.
I think watching the on line video prior to set up made set up easier. I never write reviews but I so like this product I thought I should share my opinion.
However, the manufacturer has an assembly video that sows what you need to know if you stop the video and examine the parts in question.
Answer: no
