We produce design tools for land-vehicle design.
The tool is an app targeting the iPhone 15 Pro, a portable screen and a Magic Keyboard. It can be used to specify a design as part of a design process for non-motorised land-vehicles such as bicycles. It targets 4 aspects of a design specification — structure, assembly, disassembly and packaging.

A description of each of the parts in the design, their order of assembly and the method to be used for each step of the process (including the tools).
A description of the corresponding disassembly process.
A description of how a dis-assembled design is to be packaged including transport considerations.

We are designing a bicycle trailer optimised for carrying loads of 6
The trailer has 2 axles — a 20mm solid steel lateral-tilt balancer (with 2 16 wheels in a wide formation) and a 16mmsolid steel load balancer (with 4 14” wheels in a narrow formation).
All wheels are stock and use specially designed sleeves that fit between center spoke-web assembly of the wheel and a stock ball-bearing housing that is fitted around the axle rod.
The trailer package weighs about 20kg and the longest length is about 1m.
Assembly time is about half.an hour.
The axles are arranged sequentially with the wider axle first followed by the narrower axle.
The trailer attaches to the bicycle at the seat-post and the rear wheel spindle via lightweight, rectangular steel sections.
Some modifications are made to the bike to factor in the additional load. Changing the handlebars and brakes and strengthening the frame and adding load carrying elements to the front of the bike to enable longer loads such as pipes to be carrie.
