My homebuilt Delta Recumbent Trike.

Timmy Green, my homebuilt Delta Recumbent Trike.

                      

This is my Green & Lean HPV, (Human powered vehicle) made from 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 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.

 

 

 

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.     

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

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.  

                                                                                                             

 

 

 

 

The Frame                                                                                                                                                                            Design of the frame is from a 20” Mountain bicycle frame extended using a 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.

                                                                                                         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.                                   Only 1 Front Derailer is used for gear shifting on the front triple Chain ring with standard 24,36 & 44 teeth driving a 22 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 22/18 Final Drive set up using 2 Freewheel cogs. Rear brake is only on the Right rear wheel to evenise wear & tear of driving & stopping on opposite tires.                                                 Another 18 teeth Freewheel is used on the Rear drive wheel. No Derailer is fitted to ease tire removal during puncture.

 

 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.

          

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!

          

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 Foot prints!

Very nice trike! How much does it weigh? It looks similar to my first prototype but mine was quite heavy at close to 100 pounds since I didn't really know what I was doing at the time! LOL.

...

Gus
