    There might be some very niche applications for this - perhaps extreme balance issues or core issues?

    It does not seem like a viable product.

      I could see a use for it myself - I’m a stroke “survivor” and my right leg is mobile but really not very usable. A ‘device’ like this could strengthen muscles in my right leg, while not being another bullshit static bike that has no real benefit. I could, in theory, actually go somewhere. And not take 3 days per mile!

      For steering, however… (my right arm and hand is deadweight)

        That makes sense.

        Could perhaps put cable/hydraulic bike brakes on both rear wheels, in a position where they can be operated by your left hand individually or together? It seems like this should be possible.

        This assumes that the pedals are connected to both wheels via a car-style differential so that the rear wheels aren’t locked together and steering is actually possible.

      Certain types of spinal injuries make standing and walking difficult requiring the use of a wheelchair, but still permit pedaling.

      I have a family member that has to use a wheelchair but uses an exercise bike for his rehabilitation.

      Maybe certain kinds of back pain?

      Or knee/muscle issues that prevent the patient from being able to hold their own weight, but not from pedaling.

    What is the chain connected to? If it’s both the back wheels, how do you steer? Is it actually connected to a sex toy mechanism in the seat?

      A quick google for ‘tricycle differential’ returns a bunch of products that are probably in the right power range and would do the trick. Still need hand braking to actually achieve steering.

        I like to think of it being only connected to one wheel with the other one free, so you can spin around in circles until you do a barrel roll. It’s the only form of euthanasia approved by insurance companies in the US, trademarked funthanasia.

      It’s connected to a generator that charges the battery for the electric motor that powers the wheelchair.

    They were so focused on whether they could that they didn’t stop to consider whether it even made sense in the first place.

    It can work if you have someone sitting on your lap. it looks kinda dagerous tho. the chain needs a cover.
