Purchased a 2nd hand 2023 Turbo Vado 5.0 for my spouse who has a rotten right shoulder (pending replacement surgery). She is still looking to ride but we were looking for some tips or ideas finding a taller stem, or am I able to swap the handlebars out for a more swept back (Mary Poppins) style. Went to my local Specialized dealer and they advised that they were not able to swap out the stock handlebar? Seemed a bit strange, or is there something particular about the Vado? Thanks for any tips or ideas.
