So the DF-XL arrived today.

The seat came NOT installed.

Looks like I should:

• Measure my top of shoulders to bottom of butt distance.
• Adjust the coat hanger height to approximate the distance just measured plus one inch.
• Adjust the coat hanger height until the top of my shoulders no longer hit the bottom lip of the cockpit opening while sitting in the seat.
• Now remove the front wheels.
• Raise the front of the seat to position the middle of the seat side to be in line with the pre-drilled hole in the wheel well.
• Using a drill bit the same size as the hole already in the wheel well drill a matching hole in the seat.
• Do the same for the other side of the seat
• Attach the seat using the supplied hardware oriented as shown in the first picture.
• Put the wheels back on.
• Sit in the seat and adjust the peddles for the correct length.
• Add or remove chain as necessary.
