For size and/or weight limited systems with single speed you may go for top end then run hot at slower speeds or go for low end but speed limited. I don't see how this system gets over this problem. If the torque measurement is not available at the motor side then why not use rider's power...

I like the concept overall. So it is pretty much a hub drive like system implemented as a mid drive. I guess you will have one chain for the rider on the right side and another belt/chain on the left that goes directly from the motor to the hub. Does the motor have multiple internal gears...

Doesn't your bike come with integrated lights ? Try to leave it on for a long period of time.

That is torque at the rear wheel since it is a dd hub. Don't compare torque values unless they are measured at the same point. The graph that one needs is power vs rpm graph. Unfortunately only maximum values are reported hence it can be misleading. Power = Torque x rpm. Since hub is on the...

I guess you will keep on making stuff up and insult people based on your false biases. Airtags are no substitute for gps tracking, you are welcome to ask apple and see what they say. And I am a good 20+ years younger to be a boomer. No wonder why so many people have put you on their ignore list.

Where do you see Wren fork listed as 9lbs? Their beefy mtb offerings are in the 4lbs range and I don't see how this one is twice the weight ? GPS tracking is far superior to airtags. Airtags relies on passing next to an apple device hence its updates are not frequent, significantly delayed and...

What are the improvements in the new motor ?

Very nice video Ravi. I wish you did many more videos like this one.

Chainrings don't have any effect on the sensors. You should be able to change it like any regular bike. Just make sure that the number of links on the chain is right.

Please don't make numbers up. Wren fork doesn't add that much(the fork itself is probably 4-5lbs and the oem fork is also of similar weight), if it adds anything. While the bike is heavy I don't know another ebike with 1kwh battery and a dd motor that weights significantly less. Don't look at...

250W is more than enough as long as you have a large enough cassette/ small enough chainring that you can ride at a cadence >60 while being slow enough. Ebikes are great at adding cardio to your daily routine while commuting. I do hills like that on the picture on eco when I don't care about the...

Your confusion is, you start with torque which is a measure of rotational force then add rpm into the mix and venture into power. Put rotational speed aside. A 90kg human being putting all its weight on a pedal of length 17.5cm generates(maybe the word generate is creating this confusion)...

I remember Flx being in the 5k range and Frey was also being a bit cheaper and having better suspension, that was what I was talking about. I may be mistaken.

It seems there is a significant price increase and some of the offerings have switched to lesser components. Am I correct ?

Physics is physics, the less power you have the slower you go(many of us pointed this out while fanboys were singing a different song). Torque by itself is a meaningless number and it is used for marketing too much. By putting my weight on one pedal I can generate far more torque then 85nm. By...

I came across this one https://bafang-e.com/en/products/motors/hr-series/h700/. Seems to have two gears(probably just changing rotation direction to switch between high and low gear). It should be a good solution to give power limited hub motors a good climbing ability. I couldn't find any...

Looks almost the same as Animaris Seatpost suspension. Great to hear that you have started to take preorders. Best of luck.

It was erroneous on my part to only mention the state where the wheel locks. It doesn't need to completely lock, the leftover kinetic energy that can not be absorbed by friction etc. will translate into rotational motion. The whole bike will simply rotate with the front wheel. While abs name...

I believe some of the motorcycle abs systems also make use of gyroscopes. And what you point out is the job of an abs whether it is a bicycle or a motorcycle am I mistaken ? I agree that because cg is higher with ebikes they are easier to flip over.

This is what me and several others have been saying. It is perfectly in line with the theory. These mainstream mid drives are nice for technical riding but they fail to deliver higher speeds at sustained climbs. I can cap my bosch cx on tour, that is it gives nothing more when I switch to emtb...
