I think I have an Observer sidecar. I have scratched and
found an ACE-logo.But the chassi seems more to be an Indian
But my sidecar has no door..

Thanks Doug for sharing this info about the FLXI. I'll be
interested to look tonight to see if my frame has two

The sidecar on the Henderson is a FLXI Arrow Speedster. I
have one fitted to my 1921 Ace, that I bought from Dave
Shirk many years ago. It came as a generic sidecar
probably to fit an Indian twin. As I found out during the
assembly, four cylinder motorcycles have wider sidecar
frames due to the width of the Four's chassis. So I cut
the rear frame (1.125" solid bar stock) where it mounts to
the back of the bike, and extended it 2 inches. Up front,
I cut off the leading connection and made a special one to
fit only the Ace which has a special bend in it to clear
the foot brake pedal (thank you Richard Morris for making
me a template). At the rear, it didn't quite mate up
right, so I made an offset knuckle to secure the rear
sidecar frame to the axle plate of the Ace. The Johnson
bar on the FLXI is a laminated spring which bolts to the
sidecar main frame with U-bolt clamps.

I did a similar conversion to the former Lou Lichva Ace
while Mike James owned it. Lou used to swap his FLXI
Observer sidecar between his 1924 Henderson DeLuxe and his
1922 Ace. It made sense later as he had a goofy bent bolt
about 10-12 inches long to secure the front of the sidecar
frame to the Ace's single downtube (the Henderson had twin
downtubes). I rode this Ace several times on the road and
it was a perfect handling outfit. Lou knew his sidecars.
The Observer was originally sold only to Ace. It was their
best sidecar according to Red Wolverton. When Ace went
belly up, FLXI was left with their premier sidecar and no
motorcycle. So they altered it to fit the Henderson, both
long frame and short frame models. Lou's sidecar was one
of these as it had two castings on the main frame to place
the Johnson bar in one of two places depending on which
model Henderson was going to carry the rig.

Pulled over for a photo shoot, riding Henderson's with
sidecars does not suck.
