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).
If you have the 48 Volt, 10 amp hour battery, and are riding using level 7 out of 9, it sounds like you are probably going at a speed of at least over 20 mph. (probably 23 to 25 if you are in gear 7). If its a 500 watt motor, then a range of 20 to 21 miles at that level of assist, is actually about normal. To get to maybe close to a 40 mile range, you'd need to be in Level 1, or MAYBE Level 2 assist, and likely only traveling at speeds of between 10 and 12 mph. On mostly flat terrain (i.e. no hills or very small ones). That is the only way you will get longer range. Wind resistance alone, really increases once you are doing 15 mph, and much worse at 20 mph. The wind resistance curve is not linear as speed increases, and generally increases at a higher rate of change once you get around 15 mph and higher. Also unless you are REALLY strong and in very good shape, the energy your legs provide is probably only doing a third of the work, once you are over 20 mph, and in Level 7. The Ride1Up has a cadence sensor, so that motor is drawing a lot of watts out of the battery when you are on level 7, because that type of controller and display, (bafang) are speed range based levels. Lastly, on the bafang display, there is almost no difference in the power drawn once you get above level 5. Its almost flat or barely any increase of power or speed after Level 5. Sort of joke, but you see this all the time on their aftermarket kits and displays that have capability of 9 levels. Usually I just change them back to being only Levels 1 through 5. (can be done in the second level menu).
10 amp hour capacity, and 48 volts, with a 500 watt motor, seems like a 'stretch' to make 50 miles, especially with cadence sensing, so they are really pushing the 'truth' envelope on that one. It could possibly be done if you had torque sensing, like what existed on the Surface 604 Rook and Colt, that have a 48 Volt battery, 10 AH, and 500 watt motor. But again, stay in level 1 only, keep your speed down, and do some of your 'own work' to make it that far, keep tire pressure at the max, and maybe your range will be longer. Another variable is rider weight. If you are like a Court, and 135 lbs when in sopping wet clothes, maybe you can make that range. If you are 200 lbs, doubt it very much.
