Installing a side door on a Hannigan SP 2 sidecar?

i am considering having a small side door installed on my Hannigan SP2 sidecar.  The reason is to accommodate my spouse who recently has shoulder surgery and finds it difficult to climb out of the clamshell opening.  I also have a large standard poodle who I getting up in years and finds it difficult to jump in and out of the sidecar. It looks like it would need to be placed just in front of the fender and end at the first curve. I know it will be challenging and am looking for some sound advice from those of you way more experienced than I.i simply don’t have the$ to invest in a new sidecar. Anny thought or suggestions appreciated.  Thanks

Hi Chuck,  Have you asked Hannigan?  They might tell you, see so in so, or it will break in half if you do that.  Where are you?  They sell a seat lift that raises up and you slide out.  Was going to build one for my Miata that's lowered to the point I need to take a grandkid to pull me out.

Thanks Dave. Had a discussion with Claude today regarding options.  That was one of the suggestions he had.  Another we discussed was using a ramp I built that would allow the older dog to walk in easier.  A third option is to sell the SP2 and buy a Heritage with the side door. I totally agree that whatever is done has to maintain the structural integrity of the sidecar. Do you know how the rising seat works? Lot to think about. Really appreciate your thoughts and suggestions.

After some long discussions with several very knowledgeable people it seems the opinion is that the best way to go at this point is to open the clam shell wider by replacing the piston with a strong elastic cord and using a ramp that I built to let the older dog get into the sidecar easier.  I think making the opening wider will be less intimidating to the older dog. The younger one doesn’t care. Interesting challenges but the older dog and I have been riding together for a long time.  The longer term solution may be a sidecar with a door.  Thanks for the suggestions.

 

 

 

 

 

Cutting a hinged door into the side would be a real challenge, in my opinion.  It could probably be done, but you'd be pretty much limited to fair-weather riding.  Any seam in a sidecar body is subject to leaking water in rain.  More than one time we've stopped at a car wash to use the large vacuum cleaner to suck water out of the sidecar.  Some ask why we don't just drill drain holes in the bottom pan of the sidecar to let the water run out.  I think it would have to have a valve of some kind to let water out, but not let water run in through the drain hole.

If changing to an elastic cord will let the nose or cowling flip up more, could your wife scoot forward far enough to get her legs out on the ground to help lift herself out of the sidecar?  My wife has shoulder problems too, but so far has gotten along well with a flip-nose Motorvation Formula II LTD.

I have yet to see a Heritage on a Goldwing. I would want a side door also..

Thanks for the comments and suggestions. I extended the opening in the clam shell with paracord and that seems to be working much better for our older dog. She seems to be able to jump in and out much easier. I bought some 1/4 “ plywood and a 2x8 beam and plan to raise the floor to accommodate her even further.  My wife is still 3 mos. from riding so we’ll have to see how that works.  She’s done ok riding on the back of the bike.

We're in a similar situation right now: we have a CSC Friendship I and my wife has a hard time climbing in and out - she has had her right knee replaced, and the left knee is scheduled for this February. She also has arthritis in both hips, bulging L4 and L5 discs, and sciatica. Currently she uses a folding step stool to help her get in and out of the sidecar but we're looking at maybe modifying the car so that the front tilts up out of her way so she can step in and out easier. Being retired we don't have a ton of disposable money to buy a different sidecar - uness someone has a more accessible sidecar they want to swap for our Friendship I... 🙂

The world we live in provides people with skills and vision to fab just about anything. You can bet the right shop with fiberglass and some metal working skills could cut out frame and add a swing- out door with a seal in the lower part of the shell.

Having visited the Hannigan shop , I know they have people with skills there.

Thanks for all the suggestions and support. As of now, I have extended the clam shell opening with paracord and installed a raised floor that is level with the seat. The whole thing is carpeted and easily removable.  This seems to have made it a lot easier for the older dog to get in and out. They both did very well in Daytona for our stint during bike week. I am also planning to add a chrome grab bar to the right side of the car to make it easier for my wife to get in and out of the seat.  As of now, not seeing a new sidecar in the budget for a long while. Thanks again

Have you thought of installing a self baler from a yatch to drain water out of the chair?

You can open and close at will, and when open the water is sucked out by the movement of the yatch, but in a chair it just drains to the road as you move along.

They can be locked shut

Or a big round cork like most old school wooden lifeboats had!

Yes I can see that would workalos, but one advantage of tecknology is that the bailer does not allow wind to enter which may be a benefit of the occupants of the chair.

I chose to drill 4, 1/4 inch weep holes in my rig, 2 in front, and 2 in back so any water that gets in will find it's way out regardless of how your parked.

Works well!

I decided to go to a small shop that does vehicle restoration. Between the 2 of us we came up with a design and install that maintained the integrity of the side car structure with metal reinforcement coated with several layers of fiberglass. Works really well. American ingenuity  is not dead.  It is alive and well and living in smaller craft shops with individuals who are willing to try new designs. The door works, fits snug and lets the older dog to continue riding. If you want pics I can post.  Thanks
