BMX Sidehack

A small chariot styled sidecar for a BMX bike, designed to do the nursery run on the local cycle paths.

The chosen bike was modified by welding two steel plates on either side of the head stock tube as shown. These plates were then drilled right through with a 25mm hole cutter.

The material chosen to construct the side car was 25mm and 20mm steel conduit. This was chosen because first of all, there was some being discarded in a nearby skip and secondly this allowed the use of a commercial pipe bender to form the frame. The pipe bender was rented for a day from the local tool hire shop.

First a piece of pipe with two bends was made to give the outside frame of the sidecar.

Some blocks of wood were cut to be used as jacks to set the height of the side car floor and the bike was held upright against the wall using a clamp on the rear tyre.

The height of the sidecar was 150mm from the ground.
