Bike Friday frames

Most Bike Fridays are designed with a rider weight limit of 220lbs. The exceptions are the petite models, which are designed for 125lb maximum rider weight, and the Pocket Rocket Pro anc Crusoe, which are designed with a 190lb maximum rider weight.

Air bikes are designed for 200lb maximum rider weight. Up to 220 can be supported with heavy rider upgrade

On special order, we can build bikes with heavy rider upgrades for riders over 220lbs. This does not include the Pocket Rocket Pro or the Crusoe.

I have access to a lot of bicycle components. Curious if I could purchase a frame set (just the rear triangle, the seat mast, the main tube and the fork) from you?

I'm looking for the serial number on my bike. Is this the same thing as the frame number? There's a number on the front page of my instruction packet... is that the number?

Do you have any advice on the pivots and taking care of creaks within them?

If I were stuck somewhere and needed to have some sort of major work done, what type of metal is the frame made from?

I noticed that there is a small tab on the bottom bracket. Is this supposed to be a peg for a pump? Not sure what the function is.
