Big wheel yet short unicycle

Welcome to the community, and thank you for sharing your concept. It reminds me of this earlier discussion of a similar basal idea: Prowheel crank 127mm ISIS "MaxQ" first look - #26 by DrD.

Your description gives the impression that the mechanical design came first, and the list of benefits was assembled afterward. The reasoning feels built around the invention rather than the other way around. The design may have interesting mechanical potential, but the explanation would be much clearer if you:

  • Define a single primary user problem you want to address
  • Separate rider experience arguments from mechanical arguments
  • Support your claims with data or experience

Right now, the explanation mixes two fundamentally different topics. Throughout the post, you switch rapidly between technical design details (bearings, loads, gearing, crank spacing, frame rigidity) and usage / rider experience claims (safety, mounting ease, wind stability, pedal height, market needs). These domains require different kinds of evidence and different logic. When they are blended together, it becomes difficult to understand what problem the design is actually meant to solve.

Clearly separate the discussion into two sections:

  • What rider problem you are solving
  • How your technical design solves that problem

At the moment, several different “problems” are mentioned:

List of "problems"
  • mounting difficulty
  • high center of gravity
  • safety during falls
  • pedal height
  • wind stability
  • compactness for transport
  • enabling shorter riders to use 36ers
  • MUni performance

Because these appear as a list of possible benefits rather than a single justifiable need, it is difficult to figure out:

  • which problem is the primary one
  • which are secondary
  • which the design actually solves
  • which are speculative or hypothetical

Personally, I have thoughts on some of the technical and rider experience claims, but it is difficult to discuss them meaningfully until the overall argument is structured around a clear problem statement. Once that is clarified, it will be much easier to have a focused and productive discussion.
