Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles, heelies, or an office chair: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

Hello folx, please help me... What is the advantage of this kind of derailleur ? I just see it as an e-waste. Do I miss something ?
It's crazy that no better system than current manual derailleurs (either wired or wireless) have not been invented so far, they are so clunky compared to how brakes have evolved.
Regarding shifts in general instead, better go with those embedded into the motor e-bike probably, if you use ebikes, like pinion or effigear. You will loose the possibility to shift gear in case of depleted battery though
Transmission systems have evolved and there are really good and robust options—they just arent ultra-light and ultra-efficient, which is what cyclists want.
Gearboxes seem great but they weigh a little more and technically eat a small fraction of power. I'd have one on my bike if it were an option—i hate dérailleurs.
Maybe my next bike.
Exactly. Derailleurs are the worst part of the bike to fix and calibrate (except spokes), but by fuck are they good at what matters. They're a few parts utilizing tension and springs to hold a chain in place.
Someone should invent a sort of ROHLOFF which mounts as a standard derailleur (or as a disc brake). That would be a real advance by taking the best of both worlds.
I want a Rohloff but I'd have to sell a kidney or something lol
Well yes, for sure it's overpriced like many bike parts when you compare them to motorbikes equivalents
I Just watched a vid about the rohloff gearbox hub, it looks a good alternative for emtb too.

Yeah true. Zerode bikes are taking it on. I have an older zerode with a heavy shimano alfine gearbox but the new ones are integrated with a belt instead of a chain as well.
They say they add approx 400gr: out of 20-25 kg bike is ok I guess. I'd like to see a switch to shift manually though
