This will be my full review of the Maytech 90mm Hub Motors, Maytech Branded VESC and accompanying rear hub motor truck. I havent seen many very comprehensive reviews of the Maytech Hub Motors so I thought id post my results. I contacted Maytech on August 8 and ordered them on the 9th through Eileen at Maytech who was very nice and replied very quickly A+ on that so far. On August 22 they shipped from China and got delivered via UPS today, 2 day shipping! At first glance the packaging was great, box with bubble wrap and everything within its own box, except the truck, it was just covered in bubble wrap, which was fine. The hub motor came in at 1014g, and with the truck 1450g. In comparison to my Carvon Single Hub which weighs 1690g, though thats with another normal wheel as well. The hub looks ok so far, only thing that snot great is where the wires come out of the hub theres this kind of black goop thats spread over it and just kinda looks messy. Other than that not to bad, onto the VESC. The VESC actually looks quite nice so far though the DRV is slightly crooked , the soldering looks pretty good and the parts look legit though that doesn’t mean much lol. The truck looks ok, it doesnt way much and doesnt feel very high quality compared to the Carvon one, though it will suffice. Overall first impressions are pretty good and ill either update this post or add a reply once ive done a teardown of the hub and tested everything on my board, stay tuned!
EDIT: The hubs are advertised as 60KV though it’s more realistically around 85-90KV because I got upto 20MPH on only 6S.
So I’ve finally finished installing the hubs and got to test them out! Right off the bat I noticed the crazy torque, acceleration and braking power these sensored hubs have compared to my single drive Carvon V2! These motors are also incredibly quite, I mean dead silent compared to my Carvon thanks to im guessing the sensors. So far these hubs seem to be equally as efficient as my Carvon hub estimating about 12-13 miles of range though I will do a full drain test ride to find out. Onto the heat and current ratings of these motors because that seemed to be a big concern for many people. So far these have handled really well, I have max motor current set to 50A and it only draws around 16A at full throttle cruising though when accelerating hard it will draw a solid 50A or 60A for just a few seconds. After riding 2 miles at full throttle and starting and stopping a few times the motor only reached a max of 48C though I will see how it fairs doing longer runs. I personally dont have any hills near me so i haven’t had a chance to test the hill climbing ability though when I do ill update about that as well.
Now onto some of the cons of these hubs, which there aren’t many of. Biggest one for me personally, is speed. At full throttle these only got me upto a max of around 20mph according to my GPS. Now I am only riding these at 6S so I think at 12S you could get upto possibly 30mph though im going to work on going faster with my current setup. Compared to my Carvon which got me upto 32mph these are pretty slow. Speed is definitely the biggest problem with these for me though the acceleration, torque and quietness will definitely help out weigh that for some people. Though for me I really like going fast and I was hoping to get past 32, possibly closer 40 which simply will not be happening with these motors. Alright im going to move onto some smaller gripes I have about these motors and then ill wrap it up. First of all I didnt realize it, but that phase leads on these hubs are way to long, like even if they were half there length I think it would still be a bit much, definitely need to reduce the length of them because they take up a bunch of space inside my enclosure. Other than that I guess there isnt much else that I haven’t covered before like the black goop around where the leads come out of the motors which I still think is pretty crappy. All in all I think these are pretty good motors for the price, especially for people who dont want to go very fast, but want good acceleration and overall a board that feels nice to ride. Below are some pics of the board as well as my VESC settings.
I also took a ride with Ackmaniac’s VESC Monitor app overlay and it can be found on YouTube, HERE
Not sure why it says Sensorless but its not its in Sensored mode
