Eric Jorgensen Posted August 10, 2016 Share Posted August 10, 2016 TL;DR: Don't believe the range reporter, don't start a trip when the battery drops below 50%, and try not to push over 12 mph. Today, I decided to do a 4.5 mile ride on 50% battery. It was over flat road and the distance estimator said 9 miles, so I figure I was OK. It was smooth sailing for the first 3 miles. I ride pretty fast and my NB beeps at me to slow down, which I do, but after 3 miles the unit was down to about 25% battery and it I started getting a lot of beeps and tiltback way more extreme than the normal tiltback I get when I break 12mph. It got so bad at one point that I almost had to stop. I tried putting the speed limiter on, but it didn't really help. I basically had to limp home at about 3-6 mph. At home, the battery was around 10%. When I checked, the unit temp was 120F, which I guess is pretty hot. Ambient temp was 60F. I'm 6'2", and weigh ~230 lbs with all my gear and backpack, which is getting up there, so I think this is what I get by pushing the unit a too hard. So the big lesson is that the 9B range is probably half what is advertised for a person my size. -e 2 Quote Link to comment Share on other sites More sharing options...

Vik's Posted August 10, 2016 Share Posted August 10, 2016 @Eric Jorgensen It is what it is - punishment! And it is advisable to try to deplete 9b1's battery to almost zero at least once, just so you know what to expect if you're on a long ride. Much easier when you are prepared to crawl like a tortoise at the end of journey. Been there done that and I know how it feels... 3 Quote Link to comment Share on other sites More sharing options...
Scully Posted August 10, 2016 Share Posted August 10, 2016 lol, I did that the other day... cyclists were passing me, looking as to say 'it would be quicker to walk' Luckily it was only 3 miles - at the end of a 25 mile ride. 2 Quote Link to comment Share on other sites More sharing options...

Most of the estimators, range and speed specs used by electric wheels seems to be calculated based on very small/light weight people. At least from what I'm seeing... 1 Quote Link to comment Share on other sites More sharing options...

If u can't read the instructions, at least read the Accident Reports. Quote Link to comment Share on other sites More sharing options...
