That's also what we worry about: the noise with the multi-stage gears. We need to confirm that.

To get more torque out of something this small, we need a higher reduction ratio. We're trying out different ideas and building a demo...

Hmm, I'm not quite following. Are you talking about the clutch mechanism?

Just to make sure I’m following — are you saying that, based on the drawing, the motor might only engage when rolling the wheel...

I think a built-in torque sensor is a must. I want the motor to respond based on how hard I’m actually pedaling.

That’s definitely something worth thinking about — I haven’t fully worked out how to handle it yet, to be honest. Just to clarify — what...

Totally fair point. The idea isn’t to overpower the bike, just to complement it.

I’m planning to mount the battery on the bottle cage and will probably go with a lithium pack. I don’t need that much range cuz I won’t...

The weight and size of a motor are strongly correlated. Shrink the volume, and the weight tends to drop too.

Thanks! Are you talking about the gearbox inside the motor?

Hi everyone, The enthusiasm from our previous discussions about a lightweight road bike-compatible hub motor (targeting bikes like my...

I took a quick look — seems like Ananda actually has more than one motor that fits road bikes. But I couldn’t really find much info on...

That’s why I’ve been more drawn to minimal, lightweight assist systems — just enough support without compromising the ride feel.

One thing I think you always forget is that large parts of Europe are very hilly, unlike Warsaw and environs. Yes the 25km cut off is at...

Luna does look pretty stealth — I wouldn’t have guessed it was an e-bike just by glancing. The internal gear hub actually looks really...
