Leon’s (Seattle) has available a C7 display that will allow you to change the max pedal assist setting to 28 mph. I got mine two days ago. Easy to install. Using my phone GPS, the max mph I was able to get using PA 6 and the highest gear ratio was 26 on flat ground. A strong cyclist maybe could get 28. The other thing that I immediately noticed was the difference in PA mph in each of the PA settings. For example, using the old C7, PA1 would get you to 10.5 mph. With the new C7 , PA1 gets you to about 13.5 mph. With the old C7, I struggled get 20 mph in PA 6. Now, with the new C7, I can cruise comfortably at 20 mph in PA 4. Note the max throttle mph remains at 20. Now the not so good news: the new C7 was $99. I think it’s reasonable when you consider the increase in performance. Another thing I would like to mention is the GREAT customer service I have received from Leon’s. When I assembled my new bike there were some issues. I took the bike to a local bike shop for a complete tune up- cost was $75. I emailed Bree at Leon’s customer service with the issues and a copy of the bike shop bill. She informed me the same day that she was authorizing a refund of $75 I also talked to Ryan when I ordered the new C7. Since he has already installed the new C7 on his own bike, he was able to answer my questions.
