Interesting... http://www.ananda.com.cn/index.php/tao/view/cid/2/id/3.html ISIS spline mid-drive from China. They also have the more typical square-taper. Wonder if it will show up on some online vendors soon...

Not sure on the specifics of how it avoids rotation, but they mention a torque arm. But interesting to see a thru-axle hub on the market! But 135mm spacing is odd, because I don't think that would work with many thru-axle MTBs, which have wider spacing...

Looks neat. I am waiting for a thru-axle hub of some sort. How does this hub mount up? I see no threaded axle...

Okay...for the sake of argument (because this is the internet, after all), who makes the nicest 250W-350W hubs at this point? Either front or rear, doesn't matter.

Understood. Kind of like how the battery is 95% cells and only a small amount of ancillary material. So, how does a mid-drive, by comparison, hope to continue its weight shedding? Is it just a smaller motor with more gears and reduction? And does that eliminate a bulk of the weight because...

Can you try again to remember it's name or find it somehow? I had no luck. And yes, understandable that a small motor like the Q100 doesn't have a lot to take out. I guess if it was a lighter rim, with less of a spoke count that could help. But imagine I have a reasonably light bike already...

I recently mounted up a Q100C CST eBike system to a mid-level aluminum road frame. It's pretty nice, and the amount of assist is pretty good in that I get a workout but more easily hit a 20mph cruising speed. Maybe a 328-series would have been better (I got the 201 rpm motor) but I can always...

Thanks for the advice. So you would have gotten the 328rpm version because you want a higher top end speed?

BMS mentions 201rpm on their site. What does 260rpm feel like? I know my average cadence is around 80. Does that translate into either 201 or 260?

Those little motors look promising. What is the difference between these two? https://bmsbattery.com/ebike-kit/651-q100c-cst-36v350w-32-hole-rear-driving-hub-motor-ebike-kit.html https://bmsbattery.com/ebike-kit/618-q100c-cst-36v350w-rear-driving-ebike-hub-motor-ebike-kit.html Spoke count...

I agree wholeheartedly on this when it comes to city riding. But I am aiming for performance when I'm on my road bike, provided I'm out in the country-side. I should have mentioned that I don't need assist up to 25mph+. I would really just like it to help me overcome hills and wind at a moderate...

Oh man, I am definitely aware of the Vivax system. What with all the hoopla in UCI racing. So, it's definitely a contender I guess. But I don't know how to try it out in the US, unfortunately. I have seen some Youtube videos which kind of suggest it's not so amazing. I would definitely like a...

I think it is only a matter of a few years before the OTS (off the shelf) eBike world and hobbyist eBike world come together in a beneficial way for most people. Yes, OTS is out of many person's price range at this point. But building your own is also too hard for many (let's be serious, here)...

Hey all! I'm very much a road biker, drop bars and spandex and all that ridiculous stuff. My question is if there are any good, performance oriented eBikes out there that have drop bars, road bike geometry (a little more leaned over and stretched out), and maybe tend to be lighter than a usual...
