Gearing on Sprint 7
I recently purchased an Ezee Sprint 7. Quite pleased with it, but a couple of the hills on my commute are a bit too much for the motor-with-pedaling. I don't want to go to derailleurs; would rather shift the whole gear range about one stop lower and sacrifice 7th gear, as I don't much need it.
I know it's fairly straightforward to change the sprocket on the rear hub, but I would like to change the crankset in order to have fewer teeth on the chainring and also shorter crank arms for my - alas - short legs.
The setup is a bit of a mystery to me: the left crank arm looks like a conventional force-fit onto a square taper, with fixing bolt. Bicycle shops assure me that the right-hand side is "all one piece" and cannot be changed, usually adding that they want no part of it. Is there something about working in a bike shop that makes a person habitually cross and rude? Topic for another thread, I suppose.
If this assembly is as undesirable as I am led to believe, is there anyone who can tell me where to find correspondingly repulsive replacement parts so that I can have fewer chainring teeth and shorter crank arms? Is the process of making the change as daunting as the bike shops suggest?
Much obliged for any assistance in this regard.
Chas.
