    Bikeon, "cassette drive" torque sensing motor

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

    Bikeon, "cassette drive" torque sensing motor

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

    Bikeon, "cassette drive" torque sensing motor

    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.

    Bikeon, "cassette drive" torque sensing motor

    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...

    Bikeon, "cassette drive" torque sensing motor

    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.

    Bikeon, "cassette drive" torque sensing motor

    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.

    Bikeon, "cassette drive" torque sensing motor

    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.

    Bikeon, "cassette drive" torque sensing motor

    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.

    Bikeon, "cassette drive" torque sensing motor

    We do offer the device without battery as well. All electronic components are rated above that voltage and should work, but I never tested any other batteries except 36V and 48V. And that is the only reason we do not recommend any other battery voltage at the moment. Later we may expand the...

    Bikeon, "cassette drive" torque sensing motor

    No, the motor and sensors monitor changes in chain tension, and the motor stops operation as soon as you stop pedaling. Additionally, if you begin to backpedal, the motor detects this action and assists by rotating the cassette in reverse. This provides a riding experience that is very close...

    Bikeon, "cassette drive" torque sensing motor

    I understand your point. Once we are on track and into mass production, BikeOn will cost even less than $700. But we have to start somewhere. We are working hard to get there as soon as possible. :) Meanwhile, we appreciate our early users who put their trust and money in us, and we are doing...

    Bikeon, "cassette drive" torque sensing motor

    Yes, you can.

    Bikeon, "cassette drive" torque sensing motor

    Yes. The working range is 36V to 48V.

    Bikeon, "cassette drive" torque sensing motor

    Thank you very much for your detailed comment. I am pleased to address some of your concerns. The mounting system includes three robust points, all meticulously calculated and tested across various usage scenarios. I will create and share a video here soon to provide a detailed demonstration of...

    Bikeon, "cassette drive" torque sensing motor

    I have to disagree here. The wrap angle is smaller than in usual applications, but the effect is still in play. We use very high quality belts, which are not made of pure rubber. Some of the best and expensive bicycles use timing belts-for a reason. I appreciate your perspective. There is much...

    Bikeon, "cassette drive" torque sensing motor

    Here is a video which shows the noise level: The device is pretty quiet. One of the reasons is usage of timing belt transmission: it is a low noise, reliable and does not require any lubing or other maintenance.

    Bikeon, "cassette drive" torque sensing motor

    Yes, BikeOn works with any number of speeds (sprockets), including 12 speed cassettes. There is no need to adjust derailleur stop screw: the device has a built in stopper which prevents derailleur from going to much in and eventually hitting the red rotor.
