Problem addressed/functional need

Making a bike more useful. Uses include carrying cargo, attachment for standard garden cart, generating electricity, portable battery pack and power center. Other applications are possible..

Functional Description/approach

This is a bike rack that functions as a heavy duty rack and also can pivot to become a bike stand and electricity generator. The rack will hold more weight than a standard bicycle rack (capacity still untested). Potential hitch for garden cart trailer and electricity generation up to 100 watts. There will also be a removable battery pack/ power center. Total system weight should be under 20 lbs and should fit all standard bikes.

Construction/how to build

this section should include basic step by step instructions and include supporting documentation like engineering drawings, CAD or CAM files, as well as supporting photos and videos. If an instructables has already been done on it, a link to the instructable would be perfect here)

Next steps/goals/barriers

This was a successful first prototype, though there were some choices made during the build that could be reviewed.


this section might link to fabricators of the tool or tool components who are members of the farm hack community. If a fabricator has the item listed on Etsy or similar, a link to that listing would be appropriate here too
