How To Build a Bike Trailer

Easily zip around town with your groceries stored safely. Just hitch up this trailer and pedal away.


  • Step 1: Fold an electric box plate cover in half and bolt it onto your bike frame opposite the bike crank. Secure an eye bolt onto the cover plate with your drill, and then connect the trailer arm to the eye bolt with a U-clamp bolted to the trailer arm.
  • Step 2: Use your drill to screw the measured, pre-cut piece of plywood onto your trailer's frame. Drill holes around the cargo area perimeter and attach eyebolts to secure bungee cords for carrying loads.
  • FACT: In 2009, Philadelphia became the first city in the nation to ban bicyclists from using cell phones while riding.
  • TIP: If you don’t want to build your own hitch, ready-made bicycle trailer hitches are available online and in cycling specialty stores.
  • Step 3: Use a malleable metal arm, such as from a car bicycle rack. Bend the ends and compress them to lay flat against the top and side of your frame. Use your drill to bolt the arm to the frame.
  • Step 4: Use your drill to insert screws and brackets set at 90 degrees to hold the frame together.
  • Step 5: Attach the wheels to the frame with two electric box plate covers bent into position over the frame. Drill holes and secure the wheels with screws.
  • Step 6: Measure and cut the 4 pieces of 1 x 2-foot lumber to form a rectangle with ladder-like crossbars for extra support. The frame should measure 3 feet wide by 5 feet long.
