Thanks for getting that started for me. Now I have to create some additional information on the project.

Back to the PROJECT

I still has some rubbing of the rear wheel when I turned sharp at higher speeds. I looked at increasing the slot in the bottom of the Velomobile for the tire and decided to install 2 additional body mounts at the lower rear.

I first bent up some 1/8" thick X 1" wide aluminum to form some "L" brackets. Mounted the aluminum in my vice and bent it over with a plastic mallet.


I then cut the piece to the required length with my chop saw.


And rounded the corners in my 1" bench belt sander.


Here is a picture of one of the completed brackets after I cut an adjustment slot and both of the stud inserts I will be bonding in the bottom of the tub.


I decided to use one of the electric motor mount locations for an attachment point for one of the mounts.


On the other side of the frame I will add a mounting bracket to the side of the battery cradle.


Here I am brazing the mount tab to the battery cradle .


I then bonded the studs into the bottom of the tub. Tomorrow more testing before I have to go out of town for 2-weeks for work.

Not sure if I will be able to do e-mail while I am gone so it will be several weeks before I get back to the project.

Rick, Can you send a closer picture of your motor drive system and how it links in with the rear wheel, or does it drive the pedal drive side with a freewheel mounted on the shaft somehow?

The electric motor is connected to the drive system through a jackshaft. On the drive side of the jackshaft there is a freewheel that the crank is connected to and a fixed gear that goes to the rear wheel. This allows the electric motor the drive the rear wheel through the gears in the 14 speed rear hub. I hope I explained it and maybe the following pictures will help.

I started out by making some adapters to use on a square ended bottom bracket. Here I am using a tapered end mill to cut a tapered square hole.


I made 2 adapters one with threads for the freewheel and fixed gear and one that would adapt to a #25 sprocket. Here is the completed Jackshaft with the adapters and gears mounted.


This is how the motor side of the jackshaft looks mounted on the frame.


This is how the drive side looks.


Here is a close up with the motor mounted.


I hope this helps answer your questions.

Brilliant! That helps keep the motor from slowing down the rear wheel when coasting or pedaling (as is the case with my huge hub-motor) while not forcing the pedals to rotate when under electric power.

I wish I had seen this a year ago before I bought my hubmotor rear wheel. I don't think he will give me a refund on it, either.

Great design!

Thanks for the kind comments. The design for the drive system I am using has been around for I while, I first saw it used on the endless sphere site and adapted it to this vehicle.

Warren
Thanks Now I need to get you some additional information to fill in some of the gaps on the design and the frame construction.

Well I made it back from my 2-week road trip and had several packages waiting for me. I took Warren's advice and ordered some tail lights from China.
Here are the two lights I ordered, I am going to use the one on the right.


Next is where to mount the lights?
Mount them High?


or mount them lower?


I need to make up my mind and get the lights mounted. I want to be able to take the vehicle to the Niagara Velomobile Happening SAT/SUN Sept 18 - 19.

Here is a picture of the completed rear body mounts I installed earlier.I ran out of light gray primer so I used dark gray on the battery holder.

I recently saw these lights and thought of your project:

http://www.radiantz.com/cart/index1.html?c5.html&1

They have flexible LED arrays that are surface mount.

I think some molded in lights would look sexy. Or perhaps a surface mount with quick release so you can keep clean lines...

Thanks for the link, I did look at that site and boy those lights look great! I am looking to do a simple solution now to get the vehicle going and then once I figure out how it should work upgrade to better lights before I paint (that is another issue that needs to be resolved)

Well I will not be able to make it to the Niagara Velomobile gathering coming up due to work commitments. So I thought I would start thinking about what to do about the final painting.

Any thoughts on what the final color for the vehicle should be ? Blue top with silver bottom? Red, white and blue with stars? Orange and yellow? What ?

Clownfish. I think that's Orange with white stripes and a black band between the orange and white.

I think a high gloss black velomobile would be dead sexy, but being black, it would probably just end up with the "dead" part if you ever rode it on the street like that. I am partial to the crazy green colours too, like granny smith apples.

Too bad you won't make hte velo meet after all. I was looking forward to seeing you do an electric smoke show on theroad out in front of Reg's place. Maybe next year . . . sigh.

the Grand National Roadster show is a great source for paint schemes. This guy has a gallery from a number of shows and he has a love for fish as well! I think you can ship his galleries from the renaissance festival.

This seems appropriate for a "tadpole" velomobile:

How about a vinyl wrap instead of paint? You could go crazy with photo's or graphics and it could be peeled off later.

I'm personally going with Gulf orange and light blue. I think it's ironic and I just love the look on the Le Mans Porsche 917 and GT40 cars...

Florescent orange with a ANSI Safety Lime "swoosh", or the reverse. Make yourself visible, obnoxious but visible.

Ferrari Red with tan leather interior. Or if you are more of an anglophile, British racing green with white racing stripe, off center of course.

Thanks everyone for the suggestions on a paint color. I have not had any time to work on the velo for the last month or so. I think I need to pick a solid color because of my painting skills (or lack of) and then maybe add some stick on decals, Flames out the wheel wells, something like that. I also have a bunch (3000) x 3 inch pieces of 3M white reflective tape, maybe I could come up with a design using them over a solid background color.

There still is a chance (small but a chance) I may be able to make it to the Niagara Velomobile Happening comming up on the 18 & 19. It all depends if I can get everything I need to get done at work by Friday evening, we will see.

Awesome news! I'm looking forward to filming your electric smokeshow on the 7th line. I'll be taking a new velo down for Ray to uncork/unveil, plus hopefully a Team too. Larry will be there with his CF trike, and hopefully he'll bring his velo too.

I know it's rather belated at this point, but I still have those steering U-joints for you. You know, the ones I was going to give you at Indy in April? :) Maybe you can use them on your WIFE'S velomobile when you make it for her . . .

Well it has been a while since I have been able to work on the velomobile. But I was recently able to check a few more things off the to do list. While I at the Niagara Velomobile Happening, I talked with John Tetz about some steering issues I was having, mainly a heavy feeling in the steering. I traced the problem to an out of round steering shaft that was sticking in the frame bushings.
I machined a new one from an aluminum round and bolted a stainless bar to the bottom. That appears to have solved many of the issues.


Next I needed away to hold the battery to the frame more securely. I started out by covering the bottom of the battery case with several layers of cooking wrap and laying up 3 layers of fiberglass with a sheet al .060 aluminum imbedded between the first and second layers.


Once the epoxy resin cured I trimmed and cut the lower pan about 2" deep.


Next I added a center support bar to the battery holder so I could bolt the pan down.


Here is the pan bolted to the frame and the battery secured with a elastic strap I added some 1/8 inch wire brackets to make installing the strap easier.


Next I will be working on a rear fender, and a 12v lighting system with turn and brake lights.

Did a few other things to the Vm before I take it to the HPRA races in Springfield Ohio this weekend. I installed a 1/8 in plastic coated cable to hold the top in the open position. I installed it at the front so it would not interfere with the rear wheel and the seat if it as installed at the back.


One problem with this instillation is that when the top is closed the cable gets uncomfortably close to the peddles and chain ring. So I added some elastic to pull the cable away from the peddles when the top is closed.


Here is a picture that shows the cable neatly stowed at the front of the vehicle when the top is closed.


The next thing to add is some sort of latch to keep the top closed. I looked at several types of mechanical latches but decided to keep it simple and use a bungy chord latch. The cord is attached to the top and has a hook on the other end.


On the tub section I installed a concave bushing on a short bolt. The hook is just slipped on to secure the top closed.


lastly I have started to gather the parts for the turning signals and tail and brake lights. Here are the led turn signals and a DC-DC converter that I will be using to convert 24v to 12 volts.


I still need to get the switches and flasher along with the tail/ brake light.

Here are the two lights I ordered, I am going to use the one on the right.



I am using the lights on the right, too. Actually, mine are from a company called Acclaim, but they have to be made with the same molds. I ordered a Chinese version at the same time that looked identical to yours. The Acclaim version didn't have the headlight, which is useless to me anyway, and was $20 as opposed to $30 for the direct-from-China version. It's worked well for me for over a year now. The horn is loud enough to be heard on the bike path. I had to splice in some wire to make the brake light sensor reach a front wheel. I also added a switch that lets me cut off the sensor when using the parking brake. The taillight is only 1 LED, so I added a separate taillight use the Acclaim light for the brake light and turn signals.
