I think it was in response to this thread you started. You came onto a unicycle specific forum to chat about bikes… I hope you aren’t a troll, because its always nice to see more people interested in unicycling 
Welcome to the forum, and I look forward to following your progress. I’d suggest one of UDCs ‘club’ unicycles as your first (whichever size you decide on) They can take a serious beating, and are cheap enough not to have to worry about any damage caused in the learning stages.
