ochain

Hello, please write us on info@ochain.bike we would like to solve your problem!

we have been saying it for a while...

@S851: The big question is: the cranks during impact stay horizontal? There is another movement caused by rider body that cause an extra rotation of the cranks? if yes, which movement does it take? During testing we noticed that the cranks under impact want to rotate in the same direction as pedaling, due to the greater load given by the pedal in the forward position. In this case you have to add an extra speed to the chain and the result is pedal kickback phenomena. It depends on riding style but we have seen that all our riders have experienced the same behavior. there is another phenomenon related to the motions of the bike in the xy plane that adds extra speed to the chain, I am preparing a video to show it. I hope I have been clear :-)

@R-M-R: hello everybody. Sorry for my late reply but here in Italy we are at home for corona with child's and is difficult to find time to work, see the pb chat ecc... I totally agree with your numbers, are quite similar to mine with whom I started working on the project three years ago. The big question is: the cranks during impact stay horizontal?
