9. Problems Financially Initial Cost Analysis Current capital status Contributions Mitch: $20,000-$50,000 Vladimir: <$1,000 Family: $75,000 Angel Investors, VC’s, SB Bank Loans, Friends, SB Grants, etc. Product Pricing Drive System Bicycle Line Breakdown Legal: $200,000 Location: $132/sq. ft. + building = $1.2 million 6061 Aluminum: $9-$75/ft. Supplies: $175,000 Operations: Salaries, recurring payments, insurance, shipping costs and facilities. Market Research: $150,000 Start-up Manufacturing: $200,000

10. Solution Financial For the Future SB Grants Fools Friends Angel Investors VC’s SB Bank Loans How many rounds of financing, how much and when will we apply them? What aspect of the business should we look into after our first round of financing? When will we begin to break even? 2nd year, possibly?

11. Problems Design Planning Potential belt slipping Solid works/CAD generations Finding the shortcomings in existing designs and finding ways to better the design Efficient and compact shifter control Develop a full CAD render of model Use available in house WSU expertise for design review Prototype and TEST! Fine tune and adjust design

12. Solutions Design For the Future Locking mechanism Adding groves on belt and disk to reduce slippage Spring assisted push/pull gear shifting mechanism The lateral motion of the discs will be used for shifting. ISIS drive bottom bracket required strength Weight , size Variable spring designs Gears and locking mechanisms Commercially available alternatives to the standard v-belt Shifter control layout and design Compatibility with existing frames

13. Design Space Evidence Concept Drawings CAD models in progress Modeling Calculations Gear ratio ranges (.75:1 - 4:1) Material thickness/strength Research Patent searches Engineering handbooks and dissertations on CVTs

14. Major Design Decisions Using the variable sheave CVT Minimal mechanical complexity compared to other designs. Lightweight in comparison to hydraulic systems. Has been used successfully on snowmobiles, recreational vehicles and mopeds. The design has been patented already. Why hasn’t it been built? Locking position mechanism Prevent undesired drift in ratios and excessive slip. Utilizing spring force to move the drive disks Reduce the effort exerted by the rider. The shift can be better regulated if a standardized force is used.
