yes. they tend to be really poor quality new bikes that are not even that cheap.
Ebay does a range of poor quality bikes of this type.

Unless there is a need for this type of gear change due to disability etc. I would steer well clear. Components are generally terrible. If there is a disability issue, it could also affect braking strength and a drop bar bike may be the wrong thing anyway. In which case, a decent flat barred road bike might be a better option.
In summary, why do you want/need this type of gear change?
