Ah, there’s your problem! You’re doing it wrong... break out the Buffalo Trace bourbon :)

Did another 20 miles today here in NJ, a bit windy and colder, but got out nonetheless.
Regarding 'noises'; there is definitely some sort of odd noise while pushing/pedaling any speed (Eco, Tour, Sport, Turbo) and I'll give things a while to "break-in" (?), before pushing the envelope.
Although the new Bosch motor is much, much quieter than the previous generation, there is an odd noise when pedaling. I can liken it to the noise a creaky box springs make wile moving rapid on a mattress (engaged in a vigorous physical activity). That's the best way to describe the similarity of the noise I hear. If I stop pedaling, the noise stops. opinion, it's something to do with the way the motor is mounted in the frame and the resonance of the movement of the gears and/or bearings.
Either this is a defacto standard 'way it is' or I have a problem. I'd like to know if anyone else with the same bike has heard any similar noises. ONLY reason I have concerns is that these types of noises progressively got worse on my previous Super Commuter 8 leading to not only a motor replacement but ultimately in replacement of the entire bike this July.
I'm hoping it a break-in noise. Time will tell.
Good afternoon,

I hope your day is going well. I saw your post and thought you may benefit from experience with my new Trek Allant+ 9.9s. I’ve put about 300 miles on it so far, and two days ago a noise similar to one you’ve described suddenly became much more noticeable; even when pedaling with assist mode set to off.

I scheduled a maintenance appointment with my local Trek store for yesterday morning. It turns out my problem was due to some issue with the rear wheel hub. They pulled a wheel for one of the other 9.9s on the floor and used it to replace mine. It’s difficult to be sure, as this noise has been going steadily more noticeable over the past few weeks, but I think the bike is much quieter now than it was on my very first ride.

Hopefully my experience helps you. Have a great day!

God bless,
