Office Chair Bike

Step 5 Reinforce the seatpost

It looks so much more business-like after painting over the "Little Princess" motif.
I added internal steel tubing reinforcement to strengthen the seat post since I weigh more than most little princesses and the office chair lets me put lots of leverage (bending moment) on the seat post.

I split the office chair's own seat post and inserted the bike's reinfored post into the chair's seat post. I welded the split back together.
