For anyone interested, I have attached the Sprocket Teeth / Speed / Cadence chart I prepared to determine what effect on speed and cadence changing the stock 18 tooth sprocket to a 20 tooth sprocket would have. This allows me to ride at a comfortable cadence (80+- rpm) at just under the pedal assistance speed limiter. The stock gearing (with 18 tooth sprocket) is probably best for the majority, but if the stock gearing is a miss for you, this is a fairly affordable solution. Here is a good "How To" link for changing sprockets on the Bosch Performance drive from Scooteretti. They also sell the proper Bosch spider tool and Connex sprockets.
Papa G-

Thanks for posting the video. Will from Scooteretti is one of the best and a great 'go to' guy for any E-bike questions you have. He has helped many on this forum including me.

Just add a Badass box and the 20 mph limit is history. Works wonderfully on my 2018 Powerfly 5!

Thanks for the feedback. My issue was with the stock gearing. Since most of my riding is done on the Sacramento American River Bike trail, with a posted 15 mph speed limit (which most riders don't obey), and where Class 1 e-bikes are legal (Class 3's are not), I am already pushing it at 19.5 mph. If my more of my riding was on the street, I would go for a Class 3 with the greater 28 mph motor.

Hey Velome. Does the box you have affect the Purion display (ie. distance, MPH, range and etc.)? Does the system throw any error messages?

I feel your pain, my brother. I hope they can resolve the problem very soon, and that your bike provides good and dependable performance from then on. My experience with Trek has been very good, and I'm confident that they will take good care of you. Keep in touch.

I have heard great things about trek.. but my experience with my dealer has been terrible... they say , because their computer diagnostic shows no issues, that it's all in my head, they refuse to actually ride the bike to experience the issues, and say there's all these hoops to jump through before trek will open a warranty claim... I've been dealing with them since October will absolutely zero results and no communication on how they will resolve it... it's been frustrating.
But I LOVE the e bike when it works right !!! And my normal trek bikes have always been fabulous !

Sorry about your issues with your Trek. I have had pretty good luck with all of my Trek dino-bikes through the years. For your dealer to tell you that, seems like they are not interested in helping a customer at all! If I were in your shoes, I would start notifying other Trek dealers in your area to see if they could give you better service. I would also reach out to corporate directly until the right person gets the info to push it through and give assistance. Then, if all else fails, file a claim with the local BBB agency and possibly Consumer Affairs and see if they will assist. You purchased a $3600.00 dollar E-bike from them, and they are simply giving sub-standard service and denying anything is wrong with the bike when you know there is. Just b/c diagnostic software does not pick up the problem and runs error free, does not mean there also could be a deeper mechanical problem present, the diagnostics does not pick up. My opinion. Good luck!

Call Trek in WI. And give them a talking to. That worked for me. My customized Trek Pure needed a simple chain guard bracket replaced. It took weeks and finally was resolved by corporate.

Next, poke Ravi. He may have some insight.

I also helped a customer sort a Bosch issue by posting on an EU eBike site. Lots more Bosch users there.

Is there a post regarding your issues? Looked briefly,but didn’t find.

Possibly looking at the Trek Super Commuter 7. Have not had an ebike before, and kind of thinking I might miss a throttle assist. Anyone else feel the same or it does not really matter.

Just an update to an earlier post. I finally changed out my front sprocket from the stock 18T to a 20T and hit the 19.5 mph at 80 cadence I was looking for. I prefer this gearing. Rode 27.5 miles today with no issues, and no error messages! Set the tires to 40 psi (temp was 77), and liked that too.

Are the tires satisfactory for mild off road use. Dirt roads, etc?

Regarding a throttle, the Super Commuter +7 doesn't have one, but it does have the Bosch Performance Line Drive which is "Class 1" and is allowed on most bike trails. Iv'e been riding it for about 9 months and don't miss having a throttle. As far as off road riding, it is a commuter bike with fenders and no suspension. With the wide Schwalbe Super Moto tires it will do fine on a dirt roads, as well as the paved roads it was designed for, but it really isn't set up for rough terrain, single track and etc..

Especially with a $1400 price difference from the 8.
In addition to the major savings, I went with the Class 1 SC +7 instead of the Class 3 SC 8 because I commute to work on the American River Bike Trail where Class 3 e-bikes are not allowed.

FYI- Apparently there is a European version of this bike with a class 3 motor sold as STD equipment. One of the posters on this forum claimed that he purchased his Trek with this option. Nice upgrade.

Just a quick update. I took my 2018 Trek Super Commuter +7 into Trek Midtown Sacramento last week and had them update to the latest Bosch software. They also input that I was running a 20t sprocket, activated the "walk" mode and activated the "lights on/off" feature.

I got a SC7 in early May...my first E bike. I did very little research (my bad) and trusted the expertise of the Trek vendor which turns out to be very little. Soon after I discovered this site buyer’s remorse set in. Adding to the remorse was finding another shop in town advertising the SC8 for $4100. My bike had a few mechanical problems from indifferent assembly at one of their other stores. My store quickly remedied these when I drew their attention to it but I got a blank stare when I asked them to enable the walk mode via software.
All this said I love the bike though I wish I would’ve explored more options...I’m in the country outside of town and the Dual sport (or something from Specialized at a competitor’s) might have been a better choice. Initially I was leery of the fat city tires but the stability of the Moto X’s down hill, and along the broken sides of the third class lanes has been impressive. I have the largest frame which was probably too large for my short-legged 6’3” old bones. I upgraded the grips with extenders and thanks to this site got an ARS standard seat which was a big improvement though the saddle that came with the bike was an improvement in itself over what came with my old Giant CoMax. I’ve also added a Grateful Red blinker to my seatpost bag since the static fender lights seem insufficient to me especially since I’m in and out shade.
I’ve put 850miles on it which is a lot for me.
At 3K I’ll be shopping for a class three with one of the new systems. Hopefully it’ll be a little quieter and a bit lighter. But I’m happy nevertheless.
