Sidecar Project

Greetings,

Here is a picture of my latest weird project - a recumbent
sidecar for a recumbent bicycle.

This thing is a blast! My wife especially likes twisty fast
sections; she says it reminds her of "Mr. Toad's wild ride"
when she was a kid.

The hack comes off in about 30 seconds -- release three
toggles and pull a separator lever, and it's off. It goes back
on in under a minute.

For more pics and info, just go to: www.swarfrat.com and click on
the "Projects" button.

Thanks for looking -- I hope you enjoyed it!

Best regards,

Lex

Lex, very cool!

I know this reply is way late but I've got a good excuse, I just joined.

Does your wife ever get frisky and pedal too hard, running you in left hand circles?

Bob

Nope, we're pretty well matched. <G>

Seriously, I thought that might have been a problem,
but with everyone I've had passenger on this thing, it's
rode straight and true. If one or the other isn't 'pulling
their weight,' so to speak, you'll notice increased effort,
but the hack still tracks straight.

After all this time, this thing is still fun! I'm trying to work
up a suspended floating tire version, like the Hannebrink
extreme cycle for off-road, sandwash use.

I guess I'll have to grow up someday...

Sweet bike never seen one where you make the passenger help

. My dad and I built a 72 triumph bonneville/Watsonian and a 78 BMW R100/7/Hannigan sidecar rig, they both were a blast to built and still are to ride on or in. How's that thing do on gas mileage? or calories rather?

Sorry for the delay in replying -- I don't get over here as much
as I'd like!

I'm familiar with Watsonian, don't know much about Hannigan hacks,
sad to say. One of our restoration projects is a BSA B40 350cc
single; they were used extensively as sidehack rigs overseas.
After restoration, I may consider adding a hack to that one.

The recumbent bike hack gets about 50 smiles per hectare, and burns
between 500-800 calories per hour, depending on terrain, assistance
from passenger, and level of aggression on driver's part.

The 7-speed Shimano hub in the hack wheel has started acting up
a bit - not surprising as we've put a boat-load of miles on the rig,
and it was never designed to handle the tremendous sideloads of
a hack. I'll try and tune it up, and maybe machine a sprocket to
rest on the hub portion, and make it into a secondary jackshaft
driving a fixed hub on the wheel to prevent similar problems
in the future.
