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.
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.
I 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.
I 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.
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.
