July 21, 20205 yr Has anyone tried AKM hub motors ? I was considering this one https://www.aikema.com.cn/en/product/G75.html because it's particulary light Thanks Stephen
July 21, 20205 yr Woosh sells the 85SX, which I'm sure he wouldn't if he hadn't tested it out well. https://wooshbikes.co.uk/?hubkits 85SX 2.0kgs 100mm cassette 40NM AIKEMA lightweight rear motor wheels, available in 26" and 700C(28") rims

Up to 500 miles use over the last 2 months.

July 21, 20205 yr AKM motors are really good. They're very reliable, smooth and quiet with the right controller, and they pack a fair punch for their size. They're my favourite motor after trying just about every other brand over the last 10 years. Edited July 21, 20205 yr by vfr400
July 21, 20205 yr The AKM 128c is quiet as well, my preferred hub motor and is fitted to my 700c touring bike. It can take 25a @36 or 48v for hill climbing.
March 10, 20242 yr Have somebody tested the akm 75sx? Is as good as the others? Haven't found a single review

March 10, 20242 yr I have installed several AKM100H's on 20" hubs with 20x2" tires. One bike has 8000 miles. I don't think I would go any smaller than than 100H for a 26" wheel, and would prefer the larger AKM128,
March 10, 20242 yr Have somebody tested the akm 75sx? Is as good as the others? Haven't found a single review I tested one. It was sensorless, so had to be careful with choice of controller. I used a sensorless controller, but it still lost sync with it whenever I opened the the throttle to full. I solved that by experimenting with the settings. I think theyre mainly sensored now, so you shouldn't get that problem. I had it on a road bike and the power was OK, but wouldn't be my choice for a 95kg+ rider with hills. Make sure you get the right RPM for what you need. 201 rpm is OK up to 15 mph in 26" or 700c wheel. 328rpm is too fast for big wheels, but a good choice for 16" or 20".

Thanks for the info, I have one with a speed sensor included and I went with the 201 and plan to install it on 700c so its nice to know that is ok, My main concern isn't the motor's performance when it's on, but rather the amount of resistance or drag it creates when it's off and I'm pedaling on my own. Could you share your experiences regarding how this compares to riding a traditional, non-electric road bike? I plan to use the motor only occasionally and will mostly ride with it turned off. Thank you.

Thank you. All the AKM motors have relatively low resistance. All motors can take a few miles before they free-up completely.
