2. Current State of the Design
Need to add guards and paint
Deliver to customer
Include repair/part ordering information

3. Project Plan Analysis Some delay in part ordering
Tilt lock was troublesome
Initial release of bike was behind schedule
Delayed do to failure of key electrical components
Testing was rushed
Customer was unable to provide feedback at end stages

10. Successes and Failures
Made PCB instead of having lots of loose wire.
Incorporated volume control for the speaker output
Realistic Pedal and Tilt Feel
Stable, strong base
Removal of winch system
Failures
Very little objective data is provided
PCB has errors on it
Project Plan was too optimistic

11. Lessons Learned Always have several back-up plans
When in the concept design phase, don’t discount ideas that seem too simple/easy
Spend more time working together as a complete group sharing ideas. 
Continuous communication with guide and customer
Check your work many times for small errors.
Make sure all avenues are thoroughly researched before selecting an option.
Order parts week 1 and check orders

12. Suggestions for the Future
Incorporate additional objective data sensors
Incorporate everything on to 1 PCB including resizing holes of potentiometers
Improve Layout of PCB so that it is easier to mount into a box.
Change to a digital type display rather than an analog meter.
Make wire harnesses.
Replace op-amps that supply the 6V rail with a linear voltage regulator.
•Perform a patient usability study so that improvements can be made based on what the patients do not like about the bike.
•Experiment with different materials to improve the realistic feel of the resistance.
