12 Mile Bike

Rode 12 miles in 58 minutes at work on my good bike. Average 12.4. Hit high of 22.8. Way faster than the other one. Still my cadence is only in the 60s. I can't imagine going 90 and still keeping my feet on the pedals. I think getting clips will help. I am also having some trouble with the seat. It leans to far back, but I can push it forward, but then it rolls back. I will have to see if I can tighten it
