Bike : 2021 Cube Kathmandu, motor : Bosch Gen 4 Performance with 625 watt battery.
Background: I like to ride long distance and do multi day traveling by bike. I was able to routinely achieve 80+ miles on my previous bike a Giant Road E with Yamaha motor and 500 watt battery. On long trips I carried an extra 500 watt battery in order to do the 125+ mile days.
The Kathmandu with the new Bosch Gen 4 motor is near perfect for my riding needs. When motor is off there is little to no drag when pedaling. This is a big improvement over previous motors and other manufactures.
When first getting the Kathmandu, I was able to get 75 miles on a single charge. The key to expanding the range from 75 to 160+ was replacing the stock Intuvia computer with the new Bosch Nyon computer.
The Nyon is a fantastic unit. It provides lots of useful riding data. The best thing about this computer is the ability to customize the assist levels. This feature is what helped to improve the range.
The Cube Kathmandu factory setting for assist (Level 1 - level 4) : 55%, 120%, 190%, 275%. In all 4 levels the motor stays engaged until rider reaches 28 MPH
In order to get 75 miles the rider needs to use only levels 1 & 2 only (55% / 120%) of assist. The rider puts in matching effort. 190%-275% assist is fun but drains the battery accordingly.
Bosch has an app (E-Bike connect) which can be purchased ($4.) and downloaded to a phone. This pairs with the Nyon & Bosch motor and provides the ability to fully customize the asset levels.
As an example, Level 1 can be configured as follows: (At 0mph 25%, 5mph 45%, 12mph 15%, 18mph 0%)
So each Level can be totally customized for your needs. More important, you can direct the motor to shut off at certain predefined speeds. In the example above motor turns off at 18mph.
I created 4 custom levels: 1:Normal riding, 2:ultra conservative, 3: hills, 4: give me power.
The ability to customize the assist profile coupled with the new Bosch Gen 4 motor (with almost no drag) is a perfect combination and is what helped me to achieve 160+ miles on a single battery.
Be safe out there!
