Building a better Tall Bike

Step 6 Use fork as new wishbone seatstays

Now take the fork out of the front half of your top bike. take the brakes off, this will be the wish bone stay for the tall bike.

Put the fork up against the top triangle. overlap the steer tube with the seat cluster, and place the blades so they poin to the dropouts of the bottom bike, now mark the angle you'll cut the steer tube to pit the seat tube, and the length you'll cut the seatstays to but up against the back of the fork blades.
