Introduction: Timmy Green, My Homebuilt Delta Recumbent Trike.
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.
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
Step 2: Brakes
Step 3: Steering
Step 4: The Frame
Step 5: 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
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
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.
