I have just completed a 30.5 mile ride using assist 5 out of 9 and the battery has only dropped one bar, I just checked the voltage and there’s 37v left, I did a test ride to work and back as this is the first real ride I have used it but I was surprised after getting back from work ( 11 miles each way) and the battery was still reading full, this is with a new 36v 21ah battery from Jimmy with all copper connectors but I wasn’t expecting that sort of range, I was using the throttle quite a bit too on the hills and long straights, had 31mph out of it on the straight....(standard bafang 46t ring)
It’s a 36v 250w bafang still at 15amps using Karl’s special sauce settings...I am really chuffed with how it has performed and won’t even charge it tonight so I can see what sort of mileage I will get from a full battery.......
Over the moon.........

I have a 36v 417wh battery, with rear hub motor The bike weighs 22 kilos and I weigh 64. The claimed range on the flat with presumably no wind resistance is 60miles. This must be in Eco mode. Where I live in Devon is horrendously hilly, however, and the battery will drop 10% at full power on a climb at 1 in 5/6/7 of just over 300feet, so 40 wh. On a slightly less hilly route, I managed 16 miles and used 25% battery, so in keeping with what the makers boast. I have also managed, with 2 climbs of 300+ feet from sea level, including some other shorter, less steep, climbs, 20k ( the display shows only metric) with a 21% battery drain. The secret is to remain in Eco mode for as long as possible and to try moderately steep hills in what is called "City" mode, one up from Eco. Of course the one in 5/6/7 gradients have to be at full power. Switching off on the flat or downhill was also needed. But the main thing, and I have had the bike for 3 years, is to pretend you are on an ordinary bike, feathering the pedals as much as you can. So you are not necessarily going very quickly. I know this is not necessarily what an e-bike is about, but we are talking only about maximum battery range here. As we probably all know, the power required to get up steep hills does not equate to the power saved going down a similar hill and does not equate either to travelling on the flat. So, on very hilly ride, I would be lucky to get between 25-30 miles out of the battery, but with careful management, even with some moderately steep hills included,it should be possible to get considerably more than this.
One question I have, though, and it may have been answered above, is should I be riding in the lowest gear possible and at the highest cadence comfortable in order to get the lowest battery consumption?
