Frequently asked questions
What is the real-world range?
One rider logged about 26 miles per charge in pedal-assist commuting conditions, well under the 100 mile claim, likely reflecting lower-assist settings and rider weight.
Can you switch between one motor and two?
Yes, a button on the left handlebar switches between single-motor and dual-motor modes.
