TerraTrike Rover hose clamp solution … follow-up:

Here are three photos following up on the prior post about Willow’s Rover. A second hose clamp was added to back-up the first, as a “just in case” measure – this due to the fact that Willow is physically unable to fix this ongoing issue if it happens again. I want to make darn sure her seat permanently remains right where it is this time around!

Rover Hose Clamp 1

This first image is looking back towards the rear of the trike from the cross member, and shows the distance between where the seat clamp is supposed to be, and where it ended up after 3 years of riding, which was right up against the back of the angled cross member tubes. Notice the scuff marks on the top of this section of square tube frame, where the seat clamp damaged the paint on its forward ride to the angled cross members. In 2011, when Willow first got this trike, I tightened the TerraTrike seat clamp as tight as humanly possible, but I did not invoke the use of pliers. A viable solution to this issue would be if TerraTrike had a hole and pin system where the seat clamp was unable to migrate forward over time. In November 2015, I used pliers to tighten the seat clamp more than one can do with fingers alone. I then had to gently tap the cam lever shut with a small hammer, as it required more pressure to shut the lever than I could bring to bear on the butt of my hand. Still, I wanted another fail-safe measure as back-up so Willow would never again have to deal with the seat 8 inches too far forward for her leg length.

Rover Hose Clamp 2

Notice the two hose clamps now tightly in place over a thick section of inner tube to prevent any forward movement, just in case my tightening of the cam lever failed to do the job. You may probably notice if you look closely the tiny ding marks on the outside of the cam lever from the small hammer I used to gently close the lever.

Rover Hose Clamp 3

Here is a photo from the right side of the frame, directly under the leading edge of the recumbent seat, showing the two hose clamps around the inner tube rubber. That is a chain tube I am holding up so you can fully see the hose clamps, both of which were tightened with a large screwdriver with all the force I could muster to get the round clamps to conform to the square trike frame. It would be inconceivable to me at this point that Willow’s seat could ever migrate forward again! We shall see …

    I would have drilled a hole and put a bold through.

    My thought’s exactly Brian, though I’d have used a BOLT ;)

  3. A bolt is the better idea of course, but my sister has no drill (she lives hundreds of miles away from me), so I opted for the cheap, fast, and easy solution. I maintain a minimal tool set down there because she rarely has need for anything more.
