Improvements 2013



  • We reduced the weight of the trike by more than 24 pounds.
  • New light weight A-Arm assembly featuring ¾ Chromalloy alloy A-Arms.
  • Smaller lighter weight Hydraulic cylinders.
  • We are using a new kingpin system which eliminated the fixed axle and used a flat kingpin with BMX wheels with 14 mm axles  This design allows us to use off the shelf materials thus reducing the cost and a gives us a weight savings as well. The down side is the loss of the ability to use disk brakes.
  • Increased lean capabilities with new kingpin modified nut assembly.
  • New improved steering system. We changed the steering design from an under seat steer system to an over seat steering system. This will allow easier access for riders to enter and exit the trike.
  • We eliminated the freewheeling rear wheel with a coaster style rear wheel with reverse braking.
  • This will make it easier for the rider to control and brake the trike. We felt the hydraulic bakes and the gear shifting on the handle bars may be confusing if she were involved in a situation where she needed to react quickly. By simplifying the system we felt it will be safer.
  • An improved seat mounting system which allows for a more secure seat attachment mount.
  • An improved chain guide system.
The Cascade is definitely on its way to success!  We are fixing any flaws in our trike and constantly finding new aspects of the trike to improve upon and enhance.

I loved documenting this entire experience of the Lynden InvenTeam. It was one crazy experience and I'm glad I had the opportunity to record each and almost every single one of our memorable moments!
