exercise bike Exercise bike recommendation

[jderkmson]

Hey there, I want to purchase an exercise bike for my ankle’s pain like this one- https://fitnessgeko.com/fitness/sitncycle-exercise-bike-review/.

But I’m little confused that what is the right product for me. 
Is there anyone who has one at home that they could recommend; I can spend Up to $400.
Any kind of help would be grateful.

Why an exercise bike? And not an elliptical?

Actually why even a bike when you can use ur body for strength and endurance? HIIT

Get a normal bike n ride it. Road bike u can go far n fast so it's advantageous.

Second bike type, ideal for short distant travelling n cycle at own leisure... Totally forgot wha the types called though I own one. Not mountain bike something else.
