I came within a hairsbreatdh of stopping, a few weeks into starting cycle communting when a bike shop told me.my bike was a 'piece of shoot' and that 'with your size on top of that thing' it won't last the year. That was after telling me they couldn't fix the slipping gears. It was a 17mi round trip with 220m climbing, from zero, and I was running low in energy and patience with my aching legs.
Instead, I learned (successfully) how to do it myself, and bought a new bike somewhere else. I've had six different bikes since then, spent a fortune on gear, but not a penny of it there!
Oh, it was a £550 electric assist. Not a great bike, but it was still going fine several years later with the person I sold it too a few months when I bought a hibrid. S
