“Bike rack can’t stay in the street permanently.” “Past designs were too complicated to fabricate.” “Gates should create a unique entrance for driveway.” “Custom parts make projects impossible to maintain.” - Dave Prendergrast

The incline brings the road even with the curb at 5’ Swinging mechanism must be positioned a few inches above curb to avoid contact with the street
Brainstorming & Sketching
Greensgrow Bike Rack
Modeling: First Iterations
Greensgrow Bike Rack
Problems Found -Bikes collided -If positioned incorrectly bikes went too far into street -Non-intuitive configuration
Greensgrow Bike Rack -Bikes collided -Takes up large amount of space when not in use -Angle of corner causes bikes to collide
Modeling: Second Iteration
Greensgrow Bike Rack
Pros:
Cons:
-Form held most bikes -Allowed for bikes to stay well within alotted space
-Hinge proved problematic due to complexity
Client Feedback ”Having the rack swing from two posts might be a good idea.”
Greensgrow Bike Rack
“Locking to posts should allow zero room for error.”
- Ryan & Dave
Revisions
Greensgrow Bike Rack
Pros:
Cons:
-Open design aids bike placement
-Bent T-shape may be difficult to fabricate
-Lack of top rail moves away from fence aesthetic
Full scale testing Testing proved that the T shape wasn’t able to safely hold a bike
Greensgrow Bike Rack
Conclusion:
A closed loop is ideal
Models A closed form would aid in securing a cyclist’s bike lock
Greensgrow Bike Rack
Goal:
Find a strong material suitable for creating a bent loop
Material Exploration
Greensgrow Bike Rack
Cut tests were conducted on different types of metal stock Steel rods proved to be the strongest
Threaded Rod
Aluminum Conduit
Steel pipe
Steel Rod (solid)
Material Exploration
Braided steel can be easily bent and assembled, and provides a sufficient amount of security for short-term bike parking

Design Revisited
Greensgrow Bike Rack
Working With Vendors With our simple design, we contacted a local waste management company, Revolution Recovery, in an attempt to gather material.
Greensgrow Bike Rack
Working With Vendors Straight metal tubing was not easily accessible Metal banquet chairs were cut apart and incorporated into our pre-existing designs involving braided cable.

Client Feedback
Greensgrow Bike Rack
”All exposed edges should be crimped and sanded.”
“This design would require heavy welding.”
Final Model
Greensgrow Bike Rack
This model utilizes readily available hardware and standard part sizes Vertical poles provide comfortable locking point
