Obese Rider

[HMS_Dave]

I ride a recumbent trike.

As you say standing still, a trike is about the same width as a bike.
But trikes ride a lot wider than bikes on the road.
You don't want to ride in the gutter due to risk of puncture.
So your left hand wheel is roughly on the same line as a bikes wheels.
This puts the middle wheel in line with the outside of the handlebars and the right hand wheel roughly another 18" further out.
But this extra width means that you normally ride almost in a primary position.
So you tend to get better overtakes because cars have to pull out further to get passed you.
So DON'T let this fact put you off getting one if you can.

Cycling alone is not likely to cause you to lose much weight.
But as a part of a lifestyle change it can/will be a great help.
Even if it's just getting you out of the house every day.

No it won't put me off, it's going to take a while to get used to but then i haven't ridden a bike properly in 25 years until recently, so i'll hopefully pick it up. How hard can it be?

If you get a trike, then it probably helps that you haven't ridden a bike for a bit due to the difference in handling.
If you lean right on a bike then you expect it to turn right.
If you lean right on a trike then the trike will try to turn left.
This catches bike riders out the most because if you lean right to counter the camber of a road then the trike tends to turn left into the ditch .......
It's a simple trick to learn how to counteract this effect, but it does happen.
