Standard Enviolo hub vs Enviolo Trekking hub
Posted by greybeard1363@reddit | ebikes | View on Reddit | 7 comments
I have 2 ebikes one with a regular Enviolo hub and the other with the trekking version. From what I have read the regular hub has a gear ratio range of 310% from low to high. The trekking hub has a comparable range of 380%. Yesterday I was riding the bike with the trekking hub (I hardly ever ride this one so I have much more experience with the behavior of the other). I was riding a route that I am very familiar with on the bike with the regular hub. It seemed that the trekking hub had more gearing lower than the comparable gear selection that I use on the regular bike. Also while in the highest gear on each bike, I was travelling 5mph faster on the bike with the regular hub than on the bike with the trekking hub. Does anyone in this group have specs on how much lower the trekking hub gearing is compared to the regular hub?

it's not conventional higher/lower gearing. You can put those 310% anywhere you want by changing front ring/rear sprocket ratio. Gates sells different options you can fit yourself. I did that for my Enviolo TR reducing rear cog by 2T to get more low gear performance.

I'm sorry, I didn't think about it. I should have been more specific. Both bikes have mid-drive Bosch motors. There is no front ring to change. The 310% and 380% are all contained within the rear Enviolo hubs. Or, am I not understanding your reply?

> Both bikes have mid-drive Bosch motors
exactly like my Koga B10 Pace 2024 - Bosch CX gen 4, Gates belt, Enviolo TR hub.
> There is no front ring to change
there's a direct mount front chainring specific to Gates belt and Bosch motor and rear sprocket specific to Enviolo and Gates. Both are user changeable in matter of minutes.
The front ring/rear sprocket ratio decides where Enviolo gearbox range sits in matter of speed. That's what calculator I've linked allows you to decide. 310% of Enviolo City or 400% of Enviolo TR can be placed at slower or faster speed depending on your need. Play with the tool, you'll see.

Cool tool! I only kind of glanced at it earlier. So, this tells me that my question is really not about gearing of the Enviolo City vs Enviolo Trekking, but rather about the Bosch mid-drive 65 nm motor on my City bike vs my 55 nm motor on the bike with the trekking hub?
InvestigatorSenior@reddit
it might be but in case of 10nm it should not be a big difference.
What would be more noticeable is if one bike has a lower gearing due to chain ring/sprocket ratio. You can think about it as a hub bike is a single speed with some extras so same hub can be easier to push up hill (lower ring/sprocket gear ratio) or allow you to ride faster (higher ratio). This is just another layer of customization on top of range hub gives you.
Or your bikes have a different tune or mode selected. In case of Bosch Smart System bikes you can customize each mode (Eco/Tour/eMTB/Turbo, etc.) from the app. In case of older non-smart system a shop with appropriate software can tune them for you. Depending on the mode assist strength can be changed by up to 100 percentage points (i.e. form 300 to 400% of support).

Neither of my Enviolo hubs are automatic. Both require twisting the grip on the handlebar.

I wish I could help, but my bike has the enviolo heavy duty hub. On a side note, what are your thoughts on the enviolo autimatiq?
