Bought a s/h Kalkhoff ?Sahel/pro-connect (seems to be called both names) last year and been very happy with it so far. The old Super Galaxy and Muddy Fox are sadly gathering dust. Been wondering what is the best combination of cadence, gearing and level of assistance for getting decent range. Is it better to use lower gear, higher cadence and lowest level of assistance for longer period, or higher assistance, similar cadence but higher gear for shorter time? Or is this a stoopid question? (Bear with me, 76 next birthday so not as sharp as once!)
