It might not look very professional, but it is kind of fast! That is 265+ pounds from a stop to 31.4 mph in 200 meters. https://youtu.be/PmKAtrxMPr0 . It is also the most fun ride I have. It climbs steep hills with ease. If I get tired, I just lock the brakes and take a break. Plenty of room for storage. And best of all, it is cheap to make and easy to repair. I took the spandex off the wheel wells because of the heat in Texas. I will put them back on when it cools off, which might be in a couple of days. Mid 80's today, high in the 50's Wednesday. Back into the 80's Friday.

If it gets too hot down there in TX consider hopping Amtrak heading north and touring on the Seaway Trail through Upstate NY along Lake Erie and Lake Ontario.

Wooo! I can't wait!
Jerry Posted - 02/07/2018 : 13:58:45
Stay tuned, the corovelo is getting a complete make over! Pictures soon, maybe.
Jerry Posted - 01/26/2018 : 07:57:23
JMvD, if I can get it worked out and built, I'll be bringing my little corovelo with sail, out to BM this year. Actually if I get it done, I will be riding the corovelo the 1,500+ miles to BM. Hoping team Cygnus and all teams have a great year this year. If I make it to BM, I will volunteer to help out where I can.

Free mini Explorer plans on the http://www.seabreeze.com.au land sailing forum. They use a cut down windsurfing sail. It goes along at 30-40 mph, 48-64 kph, up to around 62mph, or close to 100 kph. You can buy a Whike sailing trike for $999 + $139 S&H at the nalsa.org site. I really like the Whike, but since I have a tadpole trike, this is the sail I will either buy or make https://translate.google.com/translate?hl=en&sl=es&u=http://www.rinox.es/&prev=search . Now to put a mast on the corovelo. When sailing from close hauled to a broad reach you need ballast to keep from being blown over. In the corovelo you can't lean out very far. My solution will be a flat steel plate that can be slid out either side with a weight on the end of it. A 1/2" x 3" plate around 18" long with a adjustable bolt slot and small bags of sand for ballast. I have used this method, though a longer plate, for sailing my sailboat in high winds by myself. I had made it so it would hook over the gunwales and extend out about 4' with 25-50 pounds of sand in a plastic bag. It was like having a 250 pound crew member on board.

Would you believe there is a land sailing club in north TX! North and west of Denton TX is considered the TX high plains and the wind is always blowing. Go 50 miles west of Denton and all you see is scrub type plants, rock, and long flat spots. Add in the 20-35 mph wind and you have perfect trike sailing country. I don't think I will try it at night though. Big old fat rattlesnakes like to lay on the pavement at night. I ran over one last summer at about 9 pm. He was a pissed off camper! Luckily I ran over him just below his head. I almost lost control and went down. I bet I could have hit 40+ mph sprint away from there. I see them quiet a lot about 3-4 inches across and 4-5 foot long.

Ok, enough about that. Now back to your regular program!

I could have bought two Whike's for $900 USD yesterday! They make this too, it went across America, https://www.pterosail.com . I will make my own version, maybe with a main sail and jib. Maybe only 1 1/2 sm2 jib or smaller. Or just use a large windsurf sail.

I built a wing sail out of coroplast and now will build this https://www.youtube.com/watch?annotation_id=annotation_3946725737&feature=iv&src_vid=SHv50kUzaYw&v=nHoUhlIps-4 and this https://www.youtube.com/watch?v=5mBaikawIls
using tarps. I'll be making this soon https://www.youtube.com/watch?v=AbvZQ5KrzGM . Most land sailing is done on dry lakes in CA & NV in the USA, and beaches every where else. I will going west and playing in west Texas.

Build a land sailer?

Have a look at: http://whike.com/en/ voor some inspiration

Kind regards,
JM

As soon as I get over, or ever get over, whatever I have Thom, I'll check out the speed difference. Me, my wife, daughter, and 3 grands have been sick for close to 2 months. Think we are over it, and it comes back stronger. They have closed several schools down here because of it.

Tony, I still have the nose cones. Decided they were too wide for the corovelo. Plus, I did not want to re-do the whole front. I'll use the nose cones on a couple of other projects I have going.

I sold my 3 sail boats a few years ago. Too far to drive to sail, 120 miles one way. Now I have found windsurf sailing, roller blade sailing, and I am going to build a land sailer. Watch out for that trike with sails, it might be me! Now, back to coughing. Yuck!

What happened to the noses you ordered, one was cracked?

Good job Jerry. It keeps getting sleeker. Let up know the speed increase.
Jerry Posted - 01/24/2018 : 08:06:04
The new, slimmer front by 5 inches. I have some 3M plastic tape ordered. It will look a little better once I get it re-taped with no wrinkles.

I saw this video and think this is the way I am going on wheel disc. Looks pretty good to me. https://www.youtube.com/watch?v=o6lbIKrINcg

I would only put the disc on the outside of my front wheels, and both sides on the rear. Luckily I have no rim brakes!
alevand Posted - 10/26/2017 : 13:33:26
I used fishing tape, used to pull cables through conduit. At the time American Science and surplus sold lengths reasonably, the fiberglass is less that 1/8 or so diameter encased in yellow plastic. The clips are simple to make.

I put a coat of back spray paint on to dope the fabric.

To install just flex the fiber glass rod and slip the clip through, squeeze to make it tight agenst the spokes.

In stead of making clips, you can also easily order them at velomobiel.nl. They sell wheel covers but also the different parts like clips.

Kind regards,

JM



Thanks guys, I like easy and new ideas. Tony do you use the orange fiberglass rods from the box stores?

I have been giving it more thought Tony, and wheel discs probably would make sense. I have some somewhere between here and storage in MO. One is CF from Lightning Dynamics. It is very thin and light weight. I have a couple more made from some kind of plastic. I will dig them out when I go to MO to move my stuff to the new house. We closed at 5 pm today, and I ripped up all the carpet and pads until 8:30, then drove the 50 miles home. I am pooped! Just got a shower and have to be back over there at 7 am.
Jerry Posted - 10/25/2017 : 12:41:01
With the spandex over the opening for the wheels, I don't think I need wheel disc. I didn't have time to attach the white spandex this morning though. I have been busy packing things up to start moving into the new house this evening after closing. I am taking all my coroplast, pvc, 2 bikes, tools, and other things to put in the garage. I'll keep the corovelo at RV until we get everything moved in about 2 weeks.
alevand Posted - 10/25/2017 : 08:06:28
Your making improvements, looking good.

http://recumbents.com/wisil/wheeldisk/wheeldisk.htm#Building instructions

I cut out a black Halloween polyester fabric circle bigger than the wheel, fold the edge over and sew up the tunnel. I fish a string through the tunnel. I make a hoop out of fiberglass rod, plastic coated fishing tape and join the end by crimping on small length of metal tube. I put the fabric over the hoop, tighten and tie the string. Now its like a taught drum. I make two, one on each side of the wheel, though for a velo, one cover may do with two hoops.

I make the clips using an old licence plate, and tin snips, and they are reflective. Cut strips long enough to bend into a U shape to capture the fiberglass rod.

I put a coat of back spray paint on to dope the fabric.

To install just flex the fiber glass rod and slip the clip through, squeeze to make it tight agenst the spokes.


Notice the gap between the rim and cover, these were made for an aero rim. You can see where the chain was wearing it through at the spokes after many miles.

Thanks Thom. It will look a lot better when I get rid of the tape and zip ties. It has been fun figuring out what works and what doesn't. I would love to narrow it down, but unfortunately, the front wheels are over 32" wide. I was going to build new steering bars to be able to use wheel wells, but the spandex works amazingly well over the wheels. I am going to attach the new white spandex tomorrow morning.

The one thing that really surprised me was that raising and widening the top deck made it way more aero. I also know now I need to narrow the turtle deck and lower it another inch or so. I will cut the turtle deck off just above the seat, and make it re-moveable. That will make it easier to get to the storage area and changing the rear tire. Maybe I can get it done before I get too old...er...older!

Nice Jerry. That's the best coroplast build I've seen on this forum in decades.
Jerry Posted - 10/24/2017 : 14:44:29
Thanks guys. Here is a short video of a walk around. https://youtu.be/KXbYkYbSSX0

I'd put Jerry's torque up against anyone's. Jerry, do a walk-around.
