These are some rough pictures of my trike design project as it stands today. flic.kr/s/aHsmwR8fi5Been drawing up an electric motor that I need to experiment with in order to see if the concept will work but it should as it is only a slight variant of existing outrunner motors. Still learning the CAD program that I am using to draw thing up with and I might be going to school in the spring to get some better training on it. Also designed a means of using power to make a leaning trike that uses micro load cells and variable resistors to control it. I have lots of research and testing to do before I get to the building phase as well as some tools to procure. Am also thinking of getting a set of these plans in order to help with frame design as they are pretty cheap and are race rated. theedgeproducts.com/collections/the-barracuda-r-plans/products/the-barracuda-r-plans-digital-download |

Over the past few months I have had an idea for frame material that might sound a bit bizar but I really think it might work if it is done right and I would like opinions on whether I am nuts for thinking this way.
My Idea is to use bent and laminated bamboo put together so that joined loops would support each other with metal pieces incerted in places where there would be high wear or hing points.
Then the whole structure would be covered with a carbon fiber & kevlar cloth pressed into place with a vacuum bag.

As a part of this design project I have been working on another design project that I will probably end up building before I get to building the trike. That design project is a hydraulic motor and chain drive tubing bender. flic.kr/p/2crMGjuI am also going to be changing one of my Greenlee pipe benders over to a tubing roller with a few bolt on modifications. flic.kr/p/RpTCab |

I am not a electric motor expert but i have been looking into them. I see many people like the warp 9 motors for bikes and trikes(even cars). Only 32 HP, but it has 70 ft/lbs of torque at 2100 rpm. I think a good CVT transmission with the warp 9 motor would make a quick takeoff fast trike and would take up the smallest space in the frame. Although costs could be slightly higher for the controls you will need for a electric vehicle, they are in range comparison with a gas powered trike. My donor bike for my trike build cost me $4000 used. I think any trike you build will cost you over 10 grand. www.evwest.com/catalog/product_info.php?products_id=49I hope you don't mind but i don't think a off-road chassis is a good start for a road going trike. Too many design area's that really are not compatible with street driving. Off-road design are for the lightest and minimum amount of parts to make it work. If you like a light small trike, look at the Captain America Spartan Project. That is a designed street trike. reversetrikes.freeforums.net/thread/94/spartan-trike-project-originalI hope you keep us informed and show us your building stages as you build your trike. There are a lot of good people that have experience building trikes and other vehicles. They have knowledge that they give freely you can use. Good Luck with your trike. srx660(admin) |

I am by no means an electric motor expert either but when it comes to them I prefer in wheel styled motors or hub motors because they take up less space in the vehicle and put the power where it is going rather than through a drive train.
One of my current design projects is an out runner type motor that can be modified into a hub motor fairly easily and I might be able to build it myself without to many headaches.
I believe they also have a Warp 11 now so it should have more horse power and I for some reason believe electric motor horsepower is calculated differently than internal combustion engines.
There is one thing that I will never turn away and that is help in getting to know what I am interested in better.
I like the Spartan Build from what I have been able to read of it so far but I find there is one thing that I have not found in it yet that I find lacking in most of the build articles I have read to date which is a bill of materials with dimensions and where they are to be used.
I am not talking individual parts like brake calipers, I am talking tube diameters and wall thickness so I can see what other people are using for the size of machine they are creating and the safety they are wanting.
This is the reason I am looking into the offroad buggy community because they have plans for racy venues that require a modicum of safety in there designs and I will be able to get tubing size used information for not to much money.
I can always modify their designs to meet my needs without comprimising the strength and safety factors.
Research is one of the ways I have found to cut down on potential mistakes in the building process so I do what I can to learn as much a possible before I commit to much that will cost me money I do not and will not have.
It is my desire to bring what I am doing and what I find out during my learning process to anyone who is willing to listen to what I am tryig to do.
I posed a possibility of using laminated bent bamboo hoops covered in carbon fiber and kevlar cloth as frame material and would like help in discussing it's possibility before I actually start experimenting with it to see if it might actually work.

I just uploaded some possible suspension pictures and videos to my Flikr account and hope you can tell what is going on with them and maybe enjoy them to. I am always open to recomendations even though I might not use them. flic.kr/s/aHsmwR8fi5 |

What I am intending to do for leaning and turning is a very low rpm high torque hydraulic motor on the front suspension I have designed coupled to a micro computer and either a micro load cell or a reostat possibly both.

I can't get to your flicker site. Just says they are having problems. Info for you - look at some of the image hosting links on this forum. They might work better to host pictures. Most are free. reversetrikes.freeforums.net/board/35/picture-hosting-websitesAs for tubing sizes most builders will use 1 1/2 inch 90 or 120 wall steel DOM tubing for the main frames, and smaller 1 inch 90/120 wall for bracing, etc. |

Today your flickr site was working so i looked at all the pictures there. The google site worked also.

Thank you for checking on them.
Flickr was probably having a bad day the day you origionally looked.

ahweh,
Your front suspension puts high bending loads into the arm tubes from both bump and braking forces.
