I have a 24v Synergy 7 speed ebike. I get around 17 mph unassisted, but only 18 mph with pedaling. What can I do to get more speed? (besides pedal harder) I can't afford a new kit right now, but I was wondering what to change the gearing ratios to so my pedaling is more effective. I have no clue about this. I tried reading some of the posts about this and looking at bike supply catalogs, but they usually used a lot of terms and lingo I have no clue about. Can anyone tell me in plain English what I am looking for?
