Here is a bike cart I'm planning to build. The cart frame uses 3/4" pipe welded together. The sides will most likely be chicken wire welded to the sides or shaped into a box and placed in the cart.
The wheels are 2 front 20" bike wheels. There is no suspension, but this cart will be very stable, with a low center of balance and a wide frame.
The hitch is a pipe welded to the bottom of the frame and bent at 45* with a connecter. To hook onto the bike, I will use a heavy chain snap welded to the pipe that comes of off the cart. This will hook onto an eyebolt that is bolted to the axle with a metal plate.
This will provide 360* movement for the cart. This hitch doesn't have to support much weight- it guides the cart, since the wheels are close to the middle and everything should be balanced.
As of now, I'm in the middle of welding the cart together. Soon, I will be trying it out... #bike #bike_cart #cart #pipe_welding #trailer
