I appreciated that the swytch kit is less than buying yet another bike and that it was relatively easy to install, even if you're not a bike mechanic. The pedal sensor keeps slipping out of alignment and the max battery definitely does not last 30km on a relatively flat rail to trail. The computer battery indicator does not match the battery life lights on the battery. The computer indicates 1 bar of battery left, while the battery has 2 lights remaining. The second battery I purchased seems to hold more charge longer. All that said, the swytch kit on my Trek hybrid did enable me to complete riding 100 miles in September for the Great Cycle Challenge to raise money for children's cancer research. Thanks Swytch!!! Its truly a joy to have the pedal assist!
