Possible to convert an Enviolo to a Rohloff?

[Jeremy McCreary]

you can see my HR average was higher on the HS Rohloff which makes some sense - I was leaning into it with the extra gearing enabling me to go faster, but the seat being a bit low did mean I was having to work a bit harder too.

May have been partly the carrot effect that several of us have observed, wherein greater speed (usually due to greater assist) leads to greater rider power output without conscious intent. Result: I usually get a better workout in SPORT than in OFF or ECO.

In your case, the greater speed came at least in part from higher gearing, but you still got sucked into working harder.

Quite likely.

What was noticeable was I was moving much closer to the speed of cars, so was being over taken less which I hear in theory keeps you safer...if you can be moving at aprox the same speed as traffic there is a reduced chance of an 'incident'

And yes, definitely it's undergeared for high speed in my mind

Sam, I’m just curious… What kind of bike is this? It’s ludicrous that a road (or even gravel) bike doesn’t have gearing to maintain 25MPH at a moderate cadence. Would a taller chainring (or whatever it’s called for a belt drive, if that’s what you have) do the trick or is the low gearing what you need at slow speed? I guess if it’s the latter, than the enviolo isn’t good for you.

@Chazmo It's a Riese & Muller SuperCharger 2. There is no room between the frame and the chainring for a larger front chain ring, as posted earlier, I could go 1 tooth smaller on the rear sprocket but that won't significantly change things.
Whilst some others have said they have been able to get and maintain 40-45kph on the Enviolo I've talked to most others who feel it is "under geared" for a HS Bosch motor.

I've ridden far cheaper HS eBikes with a traditional derailluer configuration and been able to maintain 40kph+ quite easily at a reasonable cadence. It's an Enviolo issue I believe (in my experience)

Hi, Sam,

OK, I got you. Sorry, I was learning as I go. I probably missed a few things along the way.

That’s a shame about the gearing. These look like sweet bikes, and I know Riese and Müller has a strong reputation. It looks like this bike is primarily marketed with a Rohloff IGH, and I suppose that’s a better combination than what you have for road riding.

Maybe you should try the smaller sprocket in the rear, although I would guess (like you) that that won’t be sufficient to make the Enviolo rear work the way you want it.

Good luck with your choices!

I also live in a very flat city (good thing) so don't really need the super low gears for climbing that both the Enviolo and the Rohloff have - just need the higher end for faster speeds

I have a Rohloff in my other bikepacking bike (non electric) and love it - it's simply they're not that cheap which is the downside!
