Thanks for the comment. A separate display is in the development plan, but it will take a while until we release it.

Here is another video, where I tried to answer some of the questions I received: Please let me know if there are any questions.

Here is a video of the device in action under load, on a flat surface and going uphill. I will soon post another video with details about the design and materials used for both the device and the battery pack.

I think it has its place and it is good for many applications. My concern is the high torque delivery. Yes, that is the case with 48V system. It is slightly lower for 36V system.

Mid drives have their own benefits. In my view we know how to build motor+transmission packages which are very lightweight and produce huge amount of toque, no problems there. The issue which I see is the torque delivery and management. Mid drives use chains for torque delivery, which is another...

36V 7Ah = 252 Wh nominal, about 280 Wh fully charged. Noted, thanks. We will offer them at some point. Here is some example (not really a mountain road, of course): There is a sufficient cooling path for the motor and electronics. The device monitors the motor and electronics temperature as...

It is in development queue. I see it as an optional light plastic cover, which snaps to the device. We have spent quite some time (years, I should say), building and testing tens of different prototypes.

I think that this is some sort of misunderstanding, and here is why. The Capstan effect, which you mentioned, is related to regular belts (such as V-belts, for example), which rely on friction between the belt surface and the pulley (drive or driven). Timing belts use teeth that mesh with the...

Thank you. We've come a long way.

The device and the battery already utilize XT60 connector, so there is no need to replace anything.

The device relies on your choice of wheel diameter in the settings to correctly calculate the speed. I can’t force anyone, but I do strongly recommend following the regulations.

We are beyond the prototyping stage and are currently shipping the device to customers. We improve the product constantly, which is one of the reasons we invested so much in the over-the-air firmware update mechanism. We have multiple issued patents in China, the EU, the US, and other...

The device monitors motor speed and chain tension for reverse pedaling operation mode. It also has a separate controller in the firmware, which takes care of it.

For class 3 you have to have a speedometer (your phone with BikeOn Connect app running). That might be a viable option to fund larger batches, we may consider it a bit later.

You can if you want to charge the battery, it will add some resistance. Otherwise you can remove the device (10 second task), toss it into your backpack and use your bike as a normal bike. Correct. Yes, that is no problem at all.
