August 20, 2013  Officially Patent pending on a USA Utility Patent! Ever have a 50 page term paper due? Well it’s a huge relief  to get that project completed!  We were patent pending on a provisional patent.  The filing of a utility patent is quite a bit more challenging. I’ve also recently taken a rear hub apart and machined it smaller to receive and attach the sized gear I need to get the correct gear ratio for the front shaft drive. The spacing for the bottom gears was a problem. I think I’ve got the perfect solution and will be testing DUAL DRIVE PROTOTYPE II shortly. That of course means new drawings and re-machining additional parts.

 

This is all part of the invention process.  On to the crowd-funding video!

 

Update: June 3, 2013

The very first front wheel drive prototype is finished and attached  to a girls beach cruiser.  It was the only bike I could find in a local store with a 1″ headset….they are all 1 1/8.  My dual crown front fork that I have been transforming came with a one inch steer tube. I will post some pictures shortly and some video!  I am truly excited about how well the gears and housing ended up coming together with the dual crown front fork set up. I am not an engineer by any stretch but I do know that whatever you can imagine can be made in a machine shop….almost anything! If you can imagine it and draw it, it can be built! I will post some gopro video shortly of the first ever, front wheel, shaft driven , hand  powered and foot powered fitness beach cruiser. Cruising to the beach just got allot more fun!

Now that I have a working prototype of my dual drive invention I intend to get back to work on the “Crowd Funding” video! There is much work to be done….but remember,  it’s “Krowon”  no work just fun!  (No work spelled backwards….keeping it fun with passion!

 

The first ever Bojon Beach Cruiser!

About Ken Haan

I have owned and operated several successful businesses in Florida since 1972. I was part owner of Bojangles and Shakers night club in the 80's. It was one of the most popular spots in the city of Fort Lauderdale for years. I have been involved in the bicycle business since 1993. In 1993 I formed the "QuickStand Corporation" and manufactured rear-mount bicycle trainers. We invented the cam "quick-release" for bike trainers and successfully licensed and defended our 5 USA Patents. We are currently "patent pending" on a "chain-less" dual drive bicycle that you pedal with your arms as well as your feet. Both the front and rear drives will utilize a drive shaft transmission and no chain! "Go Chain-less". Why the bicycle community doesn't embrace the shaft drive transmissions is beyond me. I love mine! My favorite sport is Beach Volley-Ball. If i could I would still play every day. As it is, I still get out there several times a week. On any nice day, I hop on my dual drive bike and head to the Yankee Clipper in Fort Lauderdale, for a few beach games. The cross fit benefits of my dual drive fitness bike keeps me in the game! My legacy will be that I made the dual drive bike mainstream. Why not use your arms and legs to power your bike? Using just your legs to ride seems foolish to me! Once you ride my cross fit, dual drive bike, you will feel the same way!

  1. I’m impressed, I need to say. Really rarely do I encounter a blog that’s both educative and entertaining, and let me tell you, you’ve hit the nail on the head. Your idea is excellent; the issue of changing the mind set of cyclists is one thing that crossfit exercise buffs should be seriously discussing. I was surprised that such a bicycle even exists and very happy I stumbled upon this in my search for an exercise bike that helps in cross fit training.
