Repair services of all kinds provided in workshops or other fixed locations are seldom available in remote rural areas of Kenya - as well as many other remote rural areas of the Global South.
People, who are in real need of fixing their limited equipment or finding a solution to a technical problem, are stuck for lack of basic tools and materials.
This is why mobile repair services are not only a great solution, but also one that significantly reduces costs and the use of resources, while allowing people to be active and creative in the repair process.
This step-by-step tutorial serves as an Open Source set of instructions for the prototype of a Community Repair Mobile - COREMO (Trailer Edition) intended for remote areas that are hard to access.
COREMO Trailer will provide remote communities with access to repair services through the use of the #ASKotec (Access to Skills and Knowledge - open tech emergency case) and other mobile makerspaces/tool-kits.
COREMO is currently developed in Kenya by Adam Abdumalik with support from international makerspace community members.
COREMO Trailer serves as a first stage solution for future additional variations, modules and adaptations that will include:
- Use of Solar Power (Soldering, Charging, etc.) through the addition of solar panels
- Solar electric mobility
- Scaling production, decentralized and Open Source implementation

Screwdriver
Step 2 - Preparing the parts for the metal frame
Step 2 includes:
Measuring to actual sizes
Cutting the metal to the necessary sizes
Bending the tubes
Necessary materials:
Steel (tubes, plates)
Necessary tools:
Measuring tape
Saw
Tube bender
Step 3 - Welding the metal frame
Step 3 includes:
Constructing the frame of the trailer using metal /wood. The frame should be sturdy and able to support the weight of the cargo. You can weld metal tubing or use wood planks to create the frame
Welding together the different parts of the metal frame
Necessary materials:

Vice grips
Chipping hammer
Steel wire brush
Hand File / Metal File
Step 4 - Detail: Building the hitch mechnisim (coupling)
Step 4 includes:
Building the the connection between the bicycle and the trailer by building a hitch mechanism on the trailer that will attach to your bicycle
The hitch should be strong and secure to ensure safe towing
Necessary materials:
Steel tube 25mm
Steel plates 14g
Bolts, nuts and washers
Necessary tools:
Measuring tape
Hand drill
Welding machine
Step 5 - Building the side frames
Step 5 includes:
Adding side panels to the trailer to contain the cargo and provide additional support. You can use plywood or metal sheets to create the side panels
Selecting the metals parts needed to build the side frames
Welding the side frames to the main frame
Necessary materials:
Steel (tubes, plates)
Necessary tools:
Welding machine
Hammer
Step 6 - Cutting the wooden side panels
Step 6 includes:
Measuring the size of the wooden panels needed for the metal frame
Cutting them to the sizes suited for the metal frame
Necessary materials:
Wooden plates
Necessary tools:
Angle grinder
Jig saw
File
Yard stick
Step 7 - Detail: Building all connectors for wheels and frames
Step 7 includes:
Building the connectors for the wheels, the frames and the strap-connectors: Hitches connector, Coupler, Adopters, Axles
Necessary materials:
Flat bar 29mm X 6.35mm
Bolts, washers and nuts
Necessary tools:
File
Hand drill
Wrenches
Step 8 - Painting the frame
Make sure to do an assembly test for the frame before painting!
Step 8 includes:
Painting or sealing the trailer to protect it from deterioration from weather elements
Alternatively you can also add reflective tape or lights for increased visibility on the road
Necessary materials:
Paint
Standard thinner for thinning
Sand paper p100, p80
Body filler and spreader
Necessary tools:
Paint brush 3"
Spraying machine
Step 9 - Assembling the frame
Step 9 includes assembling together the frame by fitting together walls, panels and wheels
Necessary tools:
Wrench
Hammer
Step 10 - Attaching the wheels
Step 10 includes:
Attaching the bicycle wheels to the frame using axles, nuts, and bolts
Make sure the wheels are securely attached and aligned properly for smooth rolling
Necessary materials :
2 additional bicycle wheels
Bolts
Nuts
Washers
Necessary Tools:
Wrenches
Step 11 - Building the base
Step 11 includes:
Building a base for the cargo area using plywood or a metal sheet
Cutting the base to fit the frame and attach it securely with screws or bolts
Necessary materials :
Plywood/metal sheet
Zip ties
Screws
Necessary tools :
Screw drivers
Pliers
Step 12 - Finishing the side panels
Step 12 includes:
Painting the side panels to give it some character
Make a test ride: Once the trailer is assembled, test it out to ensure that it rolls smoothly, the hitch attaches securely to your bicycle, and the cargo area is stable
Enjoy :)
Necessary materials:
Bolts, nuts and washers
Necessary tools:
Wrench
Hammer
Notes and references
Remember to take safety precautions (wear helmets and reflective clothes while using your cargo bike trailer. Ensure that all parts are securely fastened and that the trailer is balanced and stable when loaded with cargo).
