I bought a Ride1up bike about 3 weeks ago, and I am having an issue that I would like to see if others have experienced also. The range of the battery is important to me. The range for this battery is 25-50 miles per charge. After my first charge I barely squeaked out 20 miles riding mostly at Level 7 (out of 9 levels) and just a couple of moderate hills. I emailed Kevin, the owner, and asked if I had received a good battery. His response is that that mileage sounded normal for the conditions and that maybe check the psi on the tires and it may take a few cycles to get the battery "up to speed". The psi was low so I filled the tires. I have charged the battery six times hoping that a few cycles would improve the mileage. Once I got 21 miles before the battery cut out, but it is usually 20 miles per charge. If 20 miles is the standard for normal usage, then why is the low end not rated at 20? I ride about 12 miles a day, so the difference between 20 and 25 miles is the difference between charging once every two days and having to charge it every day. That is significant. Is any other Ride1up owners getting only 20 miles per charge? How on earth could a person get 50 miles out of a single charge? (BTW, I have been riding electric bikes for over 3 1/2 years and have had experience with about 6 different ebikes, so I am not a newbie to ebikes).
