How to Build a Longtail Cargo Bike

Step 14 The whole thing

We left out a lot of small steps because we used mostly found items and we lack some basic tools but hopefully this is enough information to get you started. A few things not previously mentioned are the board above the back wheel. To attach the board we pre-drilled holes through the wood and metal and then put nails through which we bent over underneath. We used fork blades welded to a metal tube as a support going from the end of the board to the rear axle. We added an extra chain to make it long enough but we are not using the large chain ring on the front of the bike so we made the chain long enough for the middle chain ring. We also welded foot pegs on the rear chain stays.
Most new rear derailleur cables should be long enough to reach, I didn't buy a new one but used a small bolt and nut to join a scrap of cable to the original to make it long enough. I did buy a new brake cable and it also works fine.
