Hey 👋

I've been riding the Reign E+1 2022 over 2,5 years now and have extensively recorded 101 trips during that time. I sold the 625 battery(worked perfectly) and so I have nothing left to compare with, so I would like to share this data with those who might need it.

A bit of information about the bike, everything is original except for the handlebars (Oneup), brake discs (Galfer), chain (Shimano XT with over 3800 km on it) and a new rear tire (DHF 2.5 WT EXO+) since April 2024. In July 2023 the motor was also changed under warranty.

The data is recorded in two Excel files and contains an extensive amount of data like outside temperature, tire pressure, average consumption, speed, trail conditions, ride notes, motor settings, etc... One file is for the 625Wh battery and the other for the 800Wh battery.
For each battery the data is presented in the Metric or Imperial standard, which suits anyone better.
The 625Wh battery has 66 recorded trips, the 800Wh battery has 35 recorded trips.

Some information for clarification:

1. The Average slope incline parameter is based on the Ascent distance and not the Total distance.

2. The Excel files are too large and extensive to read on a cell phone, so you need a laptop or a tablet.

4. Both Excel files are in a .Zip format, because the site does not allow Excel files directly.

5. The max nominal battery size/capacity are written on the battery under the tech specs so the 625(name) is in reality 621 Wh and the 800(name) is in reality 811 Wh.
To have a solid basis for the comparison the nominal max sizes were used in the math for the comparison and analysis.

The Excel tables are hard to read on the cell phone so attached here are also two(metric and imperial) images with a direct comparison of the two batteries with the average values of all of the recorded parameters.

As a bonus, a snapshot of one of my longest rides just before the descent,
22% remaining after 2181m altitude gain.

Hope this helps someone and happy ebike riding. ⚡🚲✌️
