Good overall but battery mounting required improvement for Brompton bike
The installation was straightforward and went smoothly. With the 350W motor, the bike has plenty of power for climbing hills. Since the Brompton frame doesn't have water bottle cage mounts, Geeko provides two plastic straps to secure the battery cage. While this works, the straps don't hold the cage as tightly as a fixed mount would, and it may require a slight adjustment after riding on bumpy roads. I have already logged over 1,000km of rides.
