I think you might get the bike sooner than you think. When I do the math, I get different numbers than you did.
According to your wallet, what you have is about 21K of Steem Power, and that powers down at 1/13 for 13 weeks. You should have about 1600 Steem in your wallet every week and if it stays around $1.30 then that's over $2000 a week.
You'll be riding your dream bike in less than a month.
Weird. Last time I powered down I received much less per week than that. If what you say is true, I have some feverish celebratory naked dancing to do.
In the "old" days, the power down rule was - you get 1/102 of your SP converted to Steem each week for 102 weeks. After one of the Hard Forks, it went to 1/13 over 13 weeks. Enjoy your dance!
I'm very happy that you get to have the bike of your dreams! After reading your post I was hoping someone would bring good news in the comments! Hope it works out!! Put up a post when you get it!
