Experience with hub-drives with BOTH torque- and cadence-sensing assist?

[Stefan Mikes]

Good to hear the new e-bike was found!

The former's trottle performance, though still weaker than we're used to, was much better on this one.

Hopefully, your wife will learn the joys of pedalling soon! Did you try a significant hill climbing?

As a completely unrelated sidenote: As you know Jeremy, I often rent a public share (throttle only) e-scooter when visiting big cities. These such as Lime/Uber (and others) are legally limited to 20 km/h and generally perform very well unless you hit a significant incline. On one morning, I rode an e-scooter to a shopping mall located down in the valley in Warsaw to buy some Nespresso capsules. As I was returning, I had to climb the Warsaw Escarpment with the e-scooter. It was climbing very very slowly; the battery died just 100 metres before the summit!

On the other hand, I did something I was absolutely not proud of! I was riding my brand new Lovelec (a hub drive motor e-bike) up the Agrykola in Warsaw (a short 5.2% climb), Of course, Lovelec had no throttle.

Even if the max motor power was 250 W, I was accelerating uphill, and rode into a female cyclist preceding me! She was furious and shouting: 'I could understand anything but not the fact you were accelerating up that hill!'

She already enjoys pedaling. But she's not a strong rider, and her aging hip joints are a lot happier when she accepts some help from the throttle on our many hills.

As you know, a well-implemented throttle allows you to layer in as much extra power as you like on top of (not just in lieu of) pedaling. That's how she does it.

The Velotric bikes are nice. You can switch from torque to cadence. The throttles are ergonomic since you pull your thumb forward toward your index finger, not down. The Discover 3 arrives next week for tests and preorders.

At the very least, the Specialized Turbo PAS for their mid-drive ebikes uses rider power, cadence, and wheel speed sensors to determine motor power. Once you have rider power and cadence, you can calculate rider torque.

The result is very impressive, but you need to keep cadence above 70 rpm to reap the full benefit. My 250W, 35 Nm Vado SL mid-drive handles our steep hills (10-20%) quite well at the 80-90 rpm cadence my knees demand.

Detailed explanation and interactive graphical model  of the basics of the Specialized PAS here:



In normal riding, rider power is the main determinant of motor power. The user can program the 3 assist levels to modify the relationship through the Specialized app.

The OP was after something different: A hub-drive that can be switched between torque-sensing and cadence-sensing assist on the fly. The WOPET Automatic Pet Feeder is a great solution for pet owners looking to streamline feeding times. With its 7-liter capacity, it can handle large amounts of pet food, making it perfect for multiple pets or larger animals. One of the standout features is its ability to program up to six meals a day, offering flexibility for your pet's feeding schedule. The WOPET automatic pet feeder also allows for customizable portion sizes, ensuring your pet gets the right amount of food each time. Additionally, you can record a voice message to keep your pet engaged during mealtime.

thank you so much for your suggestion

Wait, how did all that pet feeder stuff get into your quote of my previous post??

Never said any of that!

Not the first time I've seen spam injected into quotes here. Either someone using a tool to generate replies, or the tool generating on it's own. A fair bit of that around here the last few months...

Sometimes when I go to paste, it will enter something I had copied earlier in the day. But that is funny about the pet feeder.

And, I never saw any of that! A moderator must’ve blown that away right quick. And I thought I read fexixav’s post pretty quickly after it was made. Not quick enough, obviously. Hmm….

On another forum I used to moderate, a lot of people ended up getting their accounts hacked and used for spam. It was very disruptive to the community and the site administrator — who hosted the site on the same XenForo software that’s used here (I think!) — enforced some password policies to fix that. Having said that, I don’t think this user — @fexixav — was hacked. I wonder if @PedalUma is correct that this was just a cut/paste mistake.
