    I know there are a spectrum of abilities for people with CP. here are a couple of ideas depending on where your niece is.

    here is an example of a bike that is purpose designed. I rehabbed it for a bike charity I helpout with

    The bike it self is a low geared direct drive (ie. it's a fixie), it has a handle that let's a caregiver push and steer also.



    another thought might be to look into an tricyle bike. (this is my dad on one) and look at using as smaller front chaing ring and/or alternate rear gears.



    Pics of the bike you plan to modify would be helpful

    sounds like a great project
    '82 Nishiski commuter/utility
    '83 Torpado Super Strada ... cafe commuter
    '89 Miyata 1400
    Soma rush Fixie
    '78 Univega gran turismo (son's Fixie/SS)
    06 Haro x3 (son's bmx)
    Electra cruiser (wife's bike)

    looking for: De Rosa 58cm ELOS frame and fork internal cable routing

    The Nuvinci CVR hub is easy to change gears by just using a small chainring and a bigger sprocket.

    Clever thing is the ratio varies continuously , so turning the grip till it feels right is pretty intuitive .


    there are big wheel stabilizers too ,ort of a big pneumatic training wheel, set.
