Hi d8veh
Yes, I'm reading but I'm not sure what your point is....?
I'm impressed you managed to ride 54.4 miles, it would have nearly killed me even with power
I'm slowly building up the distance, 30miles is the most I've done so far in one journey but please don't believe for a moment your range from the battery is 100miles.
The range from the battery is measured when you are actually using it, other wise I could just as well that say all of my bikes have an infinite range (well rider permitting!)....if I don't use the battery.
That's very different from using the motor to assist constantly over the distance travelled. Yesterday I rode 22miles most of it with the power off for one light out on the battery, or 2.36Wh / mile. If I extrapolate that to 55miles then I would consume 130Wh....as The Panasonic has a 260Wh battery my range all of a sudden is now 110 Miles! This is just false, that's not the range from the battery at all! The best I've got is 35miles done over several trips and using economy mode.
I know from first hand experience the Panasonic system has less drag, now you may think your Sunlova / Bafang motor is low drag (and that's OK) but its not in comparison and your very own 'spin down' video proves it, the wheel stops far sooner than a normal bike wheel would...there's drag present in the motor due to the rotating planet gears.
Now, personally you may not find that to be an issue and can ride a fair old distance with one but I find it noticeable and many others on the forum have complained bitterly about it in the past...while I'm OK with my Alien and Peugeot on the flat for a few miles at speeds of 12mph or less it becomes very tiring after a while and any slight incline or head wind makes things uncomfortable.
Fitting a normal wheel to either or simply riding the PCS transforms the experience for me and I can ride further and without the same amount of struggle.
Anyhow continue to enjoy your bike as I will mine.
Regarding the Busettii, the batteries are 13Ah@48v on their web site so a capacity of 624Wh. 86miles would mean a consumption of 7.25Wh / Mile.
That's not outside the realms of possibility. Given flat terrain, favourable weather conditions, power and speed cut right back it may be possible. I've managed to get to 8.5Wh / Mile on my Peugeot over flat terrain so its not that unbelievable.
