Picture of Timmy Green, my homebuilt Delta Recumbent Trike.
                      
This is my Green & Lean HPV, (Human powered vehicle)
It is made from a combination of parts available at home right from used computer chair to a kid's outgrown bicycle.
The goal of this project is to promote Green Living in Malaysia to create the awareness of Global Warming caused by excessive noxious emissions and how we can do our part to help the Environment from further depleting through Cycling as one of our mode of Commute.      
 This HPV is designed with only 3 gearing system (initially and upgraded accordingly) for leisure Cruising, Hill climbing and  Down-hill riding. Gear ratios were specially selected for a most efficient use of our Human Power, roughly 1/8 of an Horsepower. 
 
Average speed attained with a cadence of 70 is 28km/hr distributing your weight evenly on a sponged seat ergonomically              position for a relaxed ride relieving pressure points on sensitive parts.
Apart from this it can also be used for muscles toning up & burning of Waste cholesterol as you pedal.

Step 1: Lighting

Picture of Lighting
Lighting is supplied through a Solar Charger attached on the front fairing. It charges 2 AA rechargeable alkaline batteries during the day. A six hour exposure to the sun will supply lighting to a 0.5Watt high Intensity LED front light and a rear LED light for 10hrs continuous use.     

Step 2: Brakes

Picture of Brakes
SANY0034c.JPG
Brakes are Front: Hydraulic disc on Suspension Front Fork and Rear: Simple Y pull for simplicity.                   

Step 3: Steering

Picture of Steering
SANY0043c.JPG
SANY0027c.JPG
Steering is positioned at an ergonomic location turning like a normal bike without a Tiller effect swaying the handlebars. This is accomplished using timing gears and linking them using chain with a chain tensioner.  
                                                                                                             
 
 
 
 

Step 4: The Frame

Picture of The Frame
SANY0023.JPG
SANY0021.JPG
SANY0020.JPG
SANY0022.JPG
                      Design of the frame is from a 20” Mountain bicycle frame extended using a 11/2” diameter pipe and reinforced with ¾” pipes between chain-stay to form a triangle  structure extending to the rear to take vertical and side twisting load when taking a sharp turn.The 3/4" tube between the bottom Triangle is for a Rider's weight exceeding 100kg and can be omitted if Rider is below 100kg.
                                                                                            

Step 5: A 20” front wheel combined with 2 sets of 26” wheel

Picture of A 20” front wheel combined with 2 sets of 26” wheel
             A 20” front wheel combined with 2 sets of 26” wheel for the rear is decided to have a low front and a 7” ground clearance from seat creating a low Crank position for ease of going up & down.                                 

Step 6: Only 1 Front Derailer

Picture of Only 1 Front Derailer
SANY0025.JPG
Only 1 Front Derailer is used for gear shifting on the front triple Chain ring with standard 24,36 & 44 teeth driving a standard 18 teeth Freewheel cog. A Rear Derailer is used midway to act as a Chain Tensioner. 
The Rear Axle is linked to the left Rear Wheel through a 1:1 Final Drive set up using 2 standard 18T Freewheel cogs. 
Another 18 teeth Freewheel is used on the Rear drive wheel. No Derailer is fitted to ease tire removal during puncture.
Rear brake is only on the Right rear wheel to evenise wear & tear of driving & stopping on opposite tires.

Step 7: How to build the drive shaft

Picture of How to build the drive shaft
SANY0154.JPG
Take a look at a good quality Steel rear wheel hub.
Get 2 units of those and cut it at somewhere in the middle.
Get a a thick tube /pipe of similar diameter with the Outer diameter of the hub.
Mine was about 5/8" diameter and 12" in length.

Weld this tube extending the middle of 2 precut hubs .Ensure that it is cylindrical as possible.
(Note: Ensure that the threaded portion of the hub is used to screw in a Freewheel later).

Next Extend the Inner threaded shaft with similar diameter steel rod leaving 3/4" extending the outer hub race.
Put back all the bearings and tighten the hub cone to only move freely!
You have now extended a Hub cone assembly without affecting the fit & function.

Step 8: Seat Position

Picture of Seat Position
SANY0032.JPG
SANY0034c.JPG
SANY0043.JPG
 
 Seat Position is premeasured and decided during frame length development to cater for a kid and an adult. It is made adjustable within this range.
          

Step 9:

Picture of
SANY0047.JPG
A Givi 45 liters trunk box is fitted at the rear for luggage. A space of 12” from the back seat to the box is reserve for placement of batteries to convert it to a EV (Electrical Vehicle) should there be a need!
 

Step 10: Finally my Completed HPV, Timmy Green!

SANY0076.JPG
 
Finally my Completed HPV, Timmy Green! A green human powered Vehicle with a low Center of gravity capable of 45km/hr on a level terrain.  
Design & build by a Malaysian for Malaysia! Malaysia Bolih!
Im planning to cycle from Kedah to Johor covering 800kms from North to South in 10days to promote Green if I can get enough Sponsers.
My goal is to create awareness of Global Warming in Malaysia and to be the 1st Malaysian to cycle a homemade Recumbent promoting Green Living through Cycling as one of our commute to reduce Carbon Footprints!.

Hello mister Timothy Wooi,


As I live in the most traffic jammed european city and as I'm also thinking about a more sustainable way of moving , some friend and I want start to work over a project of covered tricycle with electric assistance (because of the climate). In looking for some interesting ideas, I have been blowed away to discover your creation.
That's really amazing ! Congratulation !

Can you send me some information about this? I'm curious to know how much it has cost to you to build this? And how long? What are the size and the weight of your trike? You talked about a triple system of gear. Can you explain it to me? And finally, do you produce this trike and plan to sell it in Europe or only in Malaysia?

I'm really happy to discover your work and wish you the best for your project.


Kind regards


Kristo

Wow, this is truly well done. I've got a bunch of great old bikes under the house from when my brothers and I were growing up, they're just collecting dust these days. *chop here, weld there* I have an idea.. Thankyou very much Timmy for the idea and the steps, your trike looks much better than most $2500 Recumbent Trikes I see, and being home built, it's just even better! Good Job Mate, Worth 5 Stars

how long did it take to make your homebuilt delta recumbent trike?


Timothy Wooi (author)  alexwelton3 years ago
I took me about 2 weeks from design to spray paint.

Hi Timmy

I drive around North-, Central- and South- America
About: 
"if I can get enough Sponsers"

make it like I make

But a sign on your Trike, where you write on it what you make and where you go and following sentence:

SUPPORT
$ 1 for 1 Mile


Belief me it works... not much but just enough what I need for Food etc.

Or make a (Free) Website and there you make the same
Look my Website:

Hi Harry,
TQ so much for your advice especially on getting sponsers.
I will follow your advice to put up a sinage what you make and where you go and following sentence: SUPPORT $1 for 1 Mile.
Still do not understand on what you make means here. 
Im not good on the free web thing and will proceed with the sinage 1st.
Many tks,
Tim

This is something I've been looking to do, but i want it to go to both the rear wheels; using the gear cassette onto the jack shaft, then chain it to both rear wheels, using the rear wheels freewheel as its own differential (go left, left wheel gets all power, while the right goes faster, and freewheels, and vise versa)..
on the other hand, do you notice the right wheel dragging when accelerating or turning?
ANDY!4 years ago
sweeeeeeet.
what about adding an electric motor and some batteries to the wheel thats not foot driven? i thought adding a wheel with multiple size sprockets like from a multi-speed bike to be able to change your ratio based on weight of rider/load weight/ incline grades. with that wheel and slots to adjust alignment of motor. unless you can use the gearing system from another bike to change gears on the fly but i would be worried about chain alignment. be great trike.....wish i had acess to a welder.....one day......one day

Maybe a stupid question here, but when you say pipe, do you mean like iron water pipe like from home depot or did you use actual tubing? Don't mean to nitpick, just need to know for my build.
krelyea5 years ago
 Timmy, an excellent trike, has given me solutions to the problems I encurred trying to build my own.  But I have one question,  Where did you get or did you manufacture the fairing?  
Once again, thanks for the ideas and thanks for going and keeping green. 
Timothy Wooi (author)  krelyea5 years ago
Hi Krelyea,
Tks for your proactive comment.
In building this trike,recycle is my my focus,thus all parts and materials are taken from idle materials unless I need a specific shape/design which I need to custome make.
The fairing is taken from a stock Suzuki 100cc Scooter which cost about  Rm 50( USD13) new. Take a look at front fairing from a motorbike shop and work around that5 to suit.

Can you make an instructable for the HHO kit ?

It would be really nice
 I got real good plans from www.smacksboosters.com
good instructions with details
Timothy Wooi (author)  la3bna5 years ago
Dont worry buddy,
I will do my best to find time to write an instructable on how you can build a HHO generator using available materials at local hardware shops.Its basically a grade 316 S/Steel Spiral design HHO generator that Im trading to finance my Green projects..
All these materials were specially selected from local hardware around the globe to be user available!

Im still struggling between prototyping green gadgets,building bicycles,planning community work helping to build toilets in the interior and also trying to get sponsers to finance my ride to promote Green.
Cheers,
Tim

Hi,
Yes but later as now working on a Wind/Solar Generator to power my Computer.
Just posted a copy & paste instruction on a hho.
Tried copied the write up but the pictures did not copied somehow.  
Cheers,

Nice job. Using a front derailer is a sweet innovation and using the rear derailer just for tensioning is clever. Any reasons why you didn't decide to drive both rear wheels.
The issue with supplying power to both rear wheels is there is no easy/inexpensive  way to construct a differential.  Without which both wheels would move at the same speed as each other reguardless of what was required of them.  When cornering the outside wheel would need to spin faster then the inside wheel, as it travels a larger diameter curve, and would scrub on the ground acting as a passive brake.
very good instuctable... and wapusk, now i know what the diff in the car does... i am going to tell everyone! 
Timothy Wooi (author)  tarala5 years ago
When you go to a hobbyist shop , just take a look at a moderately high end scale model of a remote control  buggy or 4WD .Spin the right rear wheel clockwise and look at the rotation of left rear wheel.
It spins counterclockwise when theres no load applied.
A differential will automatically engage to spin faster when the opposite side experience a heavier load/traction thus improve handling at corners!
 There is a simple inexpensive way to drive two wheels that lets the wheel with the least traction, freewheel while slightly in a turn turning. A ratcheting drive cog is employed at each wheel
Timothy Wooi (author)  The Wapusk5 years ago
Tks for the englightenment to why only 1 drive is used.
Unless you want to incoperate put 2 freewheel at the 2 rear wheels,you can dive 2 wheels at the same time compensate for the turning effect like that of a differential gear assembly without wearing much of the tires!
