My wife and I came upon the e-bike scene quite unexpectedly and we were instant fans so we decided to purchase our first ever e-bikes. My wife went with the Powerfly 5 Womans which comes in a sky blue that she loves and I opted for the Powerfly 7. We both love our bikes and have enjoyed them tremendously for the last three weeks clocking in 250 miles riding on the weekends. As I primarily ride on the road and in many hills I have quickly found that the top gear is too low for me. Even on a flat I can ride in the 22-25mph range (obviously w/o the motor assist) and would prefer a larger gear to slow down my cadence. I have read on the internet that it is possible to change out the gear on the motor from 15t to 17 or even 18t. Also I am wondering if anyone has looked into changing the tires to something more inclined to the road which would help to reduce rolling resistance. Let me know if you have any suggestions as I would love to be able to ride at 25+ mph (28mph?) for extended clips.
