This is a very functional, practical, and supportive addition to my Catrike Villager, as I have a double fusion and 2 M6-C Cervical Neck Implants. It is fully adjustable to where I need the "rest" to be. The actual rest component itself, also can be flipped around to accommodate more cluttered installations, like I have, my 6 foot Glow Whip.
Which brings me to my next point. It is difficult to install and requires 2 people. The rider has to get on the bike and recline in the position that they ride in. The second person has to not only adjust the 2 clamps and the bar that holds them, which slides up and down the base and they then have to adjust the Head Rest in a good position all the while holding the component on the bike while tightening the adjustments without slipping or accidentally sliding the bar out of adjustment. It can be quite a crapshow. When this is done then the rider has to get off the bike to tighten the 2 Allen wrench screws that hold the component to the bike. There is so little room to do this, and it takes many tries to attach it. Hands get tired, holding components in a certain configured position becomes difficult. Oh, and they habe these rubber liners that have to be measured and cut and then have to go under each clamp to prevent scratching of the bike. This "octopuss" of a feat took my wife and I 2 hours to complete. It also has become apparent that no matter how tight you get the headrest piece, it still will flex back and forward. Perhaps it is how it functions?? But, it is functional and supportive for someone like me. They really should have clear step by step directions with pictures for the installation of this component. It came with none! When I called the shop where I bought it, the guy said, oh its easy to install, straightforward, you should not have any issues. This answer could not of been farther from the truth! These are the types of issues that keep people away from buying and riding a new bike! If folks do not have help and assistance with installing components on their new bike, they simply will not bother, and I find that sad. Take this review for what its worth.
