With over 30 years experience in mechanical engineering I should now something. For me this is as obvious as black and white, but hay it's your money.SlowCo said:Ecyclist said:Give yourself a favor and don't buy gear driven version of this drive. I'm not saying that chain drive is going to work well, but I'm saying that geared type will not for sure. You need very solid structure to use gear drive and you will never have that much rigidity on the bike. That's why everyone is using chains and belts. Trust me on that one. You can thank me later.
How can you predict that? The unit itself with the controller bolted between the brackets/ mounting plates makes everything very stiff/rigid. And the coarse and wide tooth profile makes sure that a little misalignment with the low rpm's at the crank doesn't matter too much. At least that is how I view the design.
