Trek Rail 5 with about 800 miles, threw codes 500, 550; Trek reset it, took a test ride, and sent me on my way. On test ride of my own at home motor kept doing its thing after I stopped pedaling, threw a code 513. Freaky. Took a video, brought bike to Trek … that was 10 days ago, they’re waiting to hear back from Bosch after providing logs, diagnotics, etc. You’d think they would swap a motor with a mind of its own as a matter of course. When my employer’s gear poses a safety threat to our customers me move pretty damn quick.
