It’s the small things

“Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.” ? H. Jackson Brown Jr."

  • I took the bike to a local shop and they put it together for me. The guys at the bike shop said the bike was high quality and a very smooth ride (I think that they all tried it out). They were very impressed. Overall I am really happy and as you said it was well worth the wait.I hope that more people
    discover the site and order more bikes. Thanks again and I hope to stay in contact from time to time.- Jerry O
  • I think folks who really need things like this are overlooked. Thank you for remembering us. It was nice dealing with Joan.
    She took the time to answer all my many questions. Very pleasant experience- Dan C
  • Absolutely love the bike. It would have been great to get a book that showed the parts, the tools needed and a single diagram for how it all goes together - I was a bit frustrated. However, I took the bike to a local bike shop and they said it's an amazing piece of equipment and worth every penny I paid.- Douglas K
  • Joan has great bikes for all sizes all the way up to 550 pounds! Great personal customer service. Quality Bikes - my bike guy was
    completely impressed by the quality of the parts on my new "A NEW LEAF." Time to go biking...- Pat O
  • I love you! I used to be an avid bike rider 10 years ago and have wanted to get back to it. However, like you I was too afraid to that my current weight would collapse a regular bike and cause serious injury. I have been looking for a bike for large riders for some time now, and am so happy to have found one.- Anonymous
