I AM sorry, you only got confused because of my poor way of explaining things. I get confused all the time and frankly am pretty sick and tired of it. I was confused when I replied to you that last time. I thought about it, then said to myself, "wait a minute!" Then I got up, grabbed Lulu and went thru the entire motions of taking her in and out of the apartment but this time watching very carefully what I was doing. So sorry to say I was wrong about how I get her back into the apartment. I told you I never go in frontwards, meaning handlebar first... WRONG!!!! Making her go in handlebar first is the ONLY way I can get her into the apartment. Seems to me that I can't do it any other way. If I try to BACK her in, I can't squeeze pass the doorway (no room for me) to get to the back end to re-position it, the handlebar would be in my way, can't climb over it. But I CAN climb over the bucket to reach the handlebars when backing her OUT the apartment....constantly correcting where the front wheel is heading. By the way, just like the doorway itself is limiting room to maneuver...there is a WALL directly to the right in back of the door in my apartment. You can't see it because the opened door is blocking it. That wall falls away after about 6 feet. But there is just enough of it to create a narrow 6ft long hallway right there in back of the door inside my apartment. Then the hallway ends and opens up into this one large room. Again...curtails maneuverability. So I have little room to maneuver both INSIDE and OUTSIDE my apartment.
You know, you would think that in this day and age of constant new discoveries...somebody'd invented something that can slip under a tire (or back over it) so tires could easily be made to move sideways. There are a whole heckuva lot of seniors like me who are cramped into these stupid tiny efficiency apartments who would sure appreciate the product. Ever try to push a wheelchair sideways if you ain't in it? Where there's seniors there's likely to be rubber for Pete's sake. Seniors put tennis balls on the feet of walkers!! No one bothers to come up with better solutions for seniors. Somebody'd make a ton of money if they did. Right now, I'm mad at myself because for sure now I've confused you beyond repair!
What about a small rug? Just big enough to fit under the back wheels. Wouldn't it glide sideways with the weight of the trike on it to sort've drag it along? Or a towel?? ....sigh, I'm tired.
They have them! Here's what they are, either for carpet or hard floors:
A 1/2" plywood piece that's 1" in from the doorway with a bevel on the front edge to make rolling it up easier without using "power" would work, since it would be very low off the ground.... no casters.
Your towel idea would be so easy to try,... Go For it using a beach towel since they are longer and have good nap? are thicker.. Some towels have rope handles sewn in which would work good.
As to which way it "goes in" ...and I say this "in theory", since obviously, I'm not there:
I maintain that if you drive forward, past your doorway, open the door and then get behind it and pull it towards the opening is how I would start. You can continue to pull it into the doorway until that's no longer possible with the wheels turned hard left. The back end should now be started into the opening, and in far enough to get around the front and push it the rest of the way in...
Having worked with motorcycles and bicycles all my life, I know that handlebars can be rotated, shortened, replaced, reconfigured which may help with your width constraints. I don't know if that's a reasonable alternative for you?
