Not sure if it helps but I’m 210lb and have the 18l. I did a 36.75 mile ride according to endomundo, but it was at very slow speeds, averaged about 10 mph site seeing/ nature viewing. I could have gone a little faster but didn’t want to take a chance on running out of battery where we were riding no uber was going to pick me up. battery indicated about 20% at the end. I rode to my parents house 15.44 miles averaged 15 mph and started at 80% battery had a little over 40% on arrival. 350’ of ascent, temps were typical Florida summer low 90s. I normally ride in the upper teens but sometimes hit low 20mph miles on good paved bike paths / roads. By the time the battery is low, I am normally worn out, I am in my 50s. You are way lighter than me but you are also in a colder climate, and that will affect range. And if you ride faster your range will be less. I know I can upgrade the batteries to the 1600 wh pack for $800 but my wheel is doing everything I need it to now. Not sure if you can buy from ewheels or not but if you can you will get excellent support and the price difference on their website between the 18l and the xl is not that much. If I was going to buy new I would have picked up the xl. I now know I don’t really need that much battery but oddly enough you always want more. Also don’t forget that your speed will gradually be limited after 50% on the L. I never notice it till it gets below 40%, and the L seems to still move as fast as the 16s at full charge when the L is between 40 and 30% battery. The XL is not supposed to have the speed governed till it gets below 25% battery if I remember correctly. There is also the option of buying a quick charger. I have one and use it when I ride to my parents house. Hang out for a couple of hours and your battery can be fully charged, and head back home.
