I got this idea from reading about another project on Instructables using spare bike stem to create a BIKE ON A TRAINER. Expanding on that idea and having experience with PVC pipe I created another version for a road bike mounted on a TRAINER for about $20.00 and a few hours work. This would be alternative for winter riding your road/mountain bike indoors on a trainer when the roads covered with snow and ice as where I live.
Step 1: Parts List
26" X 3/4" PVC pipe:(cut into 4 pieces, 2 each of 9" and 3 3/4" sections) - (lowes $1.13 for 5')
1 1/2" x 1" PVC pipe ( cut in half) - (lowes $1.20 for 5')
1- 1" PVC Tee ( lowes $0.40)
1 - 1" 90 degree PVC elbow ( lowes $0.48)
1 - 3/4" PVC Tee ( lowes $0.40)
2 - 3/4" 90 degree PVC elbow (lowes $0.30 each)
1 - 13/16" to 1 3/4" hose clamp (size may vary dependine on size of stem on bike) (lowes $0.90)
2 - small rubber blocks - used from old parts I had in shop
1 piece of rubber intertube 4" x4" (this is optional I used a piece of pond liner) - used for free
1 plexi glass bike book holder - got mine from amazon web page from affordables for $10.99
Step 2: Making the cuts
I used a miter saw to make all the straight cuts which made clean fast cuts. The most time consuming part is fabricating the 1" Tee, after cutting it in half, to fit the stem of the bike. I used a dremel tool with a sanding bit to cove out the bottom end to fit around the stem on the bike first. After this fit I cut down the upper end closest to the handlebar to fit lengthwise then took the dremel and rounded the edges to fit the around the lower curve of the handlebars. Make sure you off set the cuts so you leave enough pipe above (as I did) or below so it can be clamped to the stem with the hose clamp. This is where I cut the rubber intertube or pond liner to fit between the modified Tee and the stem to make it fit tighter and prevent slipping.
Step 3: Assembley
With all the parts cut the rest is like putting together a puzzle. Place 1/2 the short 1" pipe in the modified Tee you fabricated in step 2. Add the 1" 90 degree tee to the other half of the 1" pipe coming out of the modified tee and have it facing towards where the handle bars of your bike. Add the 3/4" tee in the open end of the 1" 90 degree elbow so it will be parallel to the handlebars. Add the 3/4" x 3 3/4" pvc pipe to the either end of the 3/4" tee. Add the 3/4" elbows to the other end of the 3 3/4" pipes. Add the 9" pvc pipes to the other end of the 3/4" elbows. I opted not to glue anything so it could be adjustable up or down depending on the rider.
Step 4: Finishing up
The final steps are to Clamp the PVC holder to the bike with the hose clamp. I hot glued 2 small rubber pieces to the underside of the plexi glass holder to keep it from sliding off.
