Sure no problem. Yeh in Belgium the winter is rainy as hell. I don’t plan to use it that much anyway.

Those should fit right?,searchweb201602_5_10152_10151_10065_10344_10068_10342_10343_10340_10341_312_10696_5013115_10084_10083_10618_10304_10307_10820_10301_10821_10843_10059_100031_5013415_5013215_10103_5013315_10624_10623_10622_10621_10620_528,searchweb201603_6,ppcSwitch_4&algo_expid=aa2c2dba-7524-40ca-830a-7cd6ecef747f-33&algo_pvid=aa2c2dba-7524-40ca-830a-7cd6ecef747f&priceBeautifyAB=0 or maybe you can have different colour?

Read the first post. 10 euro spare urethane only black available. The one you posted seem similar but I am not sure. I would guess they are the same but who knows

Could you try them on hills? I am worried that heavier riders like me, 90kg, could have problems on hills with 110kv. You will see with the Vesc 6 variant your board will perform in a completely different way.

I have tried them on hills. I climb 3 hills along the road I do every day to work. The steepest hill is probably 15-20 degree, not sure they are almost the same. Picturse1 Maybe from the picture is not clear but most of the people get off the bike and do it by foot. I do it by bike but believe me that was one of the reason why I opted for an electric skateboard. Every morning, after breakfast and cold muscles is a nightmare. Anyhow. with backpack I am around 84-86 kg so not that far, and I can go up these hills easy. I do not feel the motor suffering. As I said the range where these motor are less efficient than the diyeboard 75Kv is from 0 to 10. There you can have almost the same torque but you have to pull a lot the throttle and by doing so dealing with high peak current, so nice battery and nice vesc needed. IF you have a minimum on momentum before take the hills, like 5kmh you can accellerate easy on the slope and reach higher speed than the 75Kv. It’s really for the first 5-10kmh that they pull more, but not a lot, becuase the diyeboard I used to go full throttle immidiately after take off, this one I prefer to give them 5 kmh more. You feel that there is more juice available, if that makes sense. Anyhow on the other hills that are like 5-10 degree, so slightly incline I went up easy at 40-45kmh. Too make it short, below 5-10kmh these hub motor 130Kv (110Kv) are lees efficient than 75Kv, which is normal, but afterwards they fly. I would really like to try the 75Kv ones. I knew only few people that used them on the forum, probably due to the price and the one that wrote in this thread use them with a ESC so the power is limited, but the top speed he gets is 36-37kmh telling me that they are probably 65Kv in reality.


Thanks for your detailed reply, waiting for the full review! There are so many exiting things to buy at the moment… Don´t really know where to start. Hubs or Unity, maybe dual Vesc 6 clone or maybe Hubs, a new battery… you get the point.


I know I know…hard life :laughing:

Anyhow with this setting the vesc run way cooler, but you loose a bit of peak current, meaning torque. Still enjoyable and plenty of speed though. vescmonitor

You also run ackmaniac on your focbox? Maybe you can adjust the throttle curve to get more start up torque? :thinking:

Yes I actually used before to lowered with the nano X. Now I am using the firefly remote Arduino based and it has a lot more of throttle control. So I do not need to lower the throttle curve. Although in this case can be that I will increase it a bit, but with this remote you only need to pull the throttle a bit further to have the same power, that’s it. On the other hand you have a lot more overall control.

The firefly…have all parts for two remotes at home but till now no time to put it together. Do you use only cables to connect all parts or did you order a pcb for your remotes?

REVIEW Hello folk! As promise I would like to share my thought about these hubs, that from now on I called MAD hubs, because it is what I thought when I ride them for the first time and to make it easier recalled them. Plus a comparison with the known ones from DIYEboard (Meepo style) The MAD hubs come in two version 75Kv and 130Kv, rated at 1800w peak current and 500w continuous. You may notice that they look like the one Torque Board was selling and indeed they have the same specs too, but I want to specify that they do not come from them. That’s also the reason why I wanted to first test them before close the GB. For the test I got the 130Kv ones, mainly because my plan was to find new hub motors to replace the DIYEboard ones, which are great, but I got used of the top speed and I wanted something more! As board I used a spud build ( having a 10s3p Samsung 30Q battery and 2 Maytech’s VESCs. I first wanted to describe the 130Kv hub motors itself. They came assembled, without the truck. On the website they advice to use Paris style trucks since you need rounded hanger ends, but if you are willing to modify other trucks, such as caliber, they will work too. For the test I bought Paris clone truck from Ali (I will post my thoughts about them later one). Here you can find some pics of the disassembled motor.

The motor size is comparable with a 6355 outrunner motor and overall looks good. I am not an expert in judging windings, but it seems legit. Looking at the motor itself I first didn’t like some design choices. The motor can is kept together with long screws that are attached only at the end. The motors mount on the truck with a collar that slides on the end of hanger and uses two screws to secure the motors in place. Last thing the PU used is a 90mm 90A which I thought would be too hard. For the installation I follow the tips given on the forum, but I will also post later on a step by step “how to do it tutorial”, with pictures for better understanding. For the comparison I chose to post the telemetry data from both the two hubs (130Kv MAD hubs Vs 75Kv DIYEboard) recorded on the same trip. For better comparison I used the same board and settings for both, the only differences were the motors and that the MAD hubs run sensored.

Results from telemetry and review:

DIYEboard 75Kv (65Kv real)

DIYEboard vescmonitor

MAD 130Kv (110Kv real) Hubs

vescmonitor MAD%20130Kv%20telemtry

Overall results 130Kv MAD hubs Vs 75Kv DIYEboard


  • Coasting capability. The MAD hubs surprised me for the free wheels experience. Don’t get me wrong also the other hubs roll well, but these ones do it better. Basically you can accelerate and then coast for longer than the other. Same thing if you push them as normal skateboard, I would say you feel 1/3 of the resistance compare the others. Really like this aspect.

  • Ride smoothness. One of the aspect that I judged as a problem at the begging was the 90A PU used. It actually turned out be way better than the other hubs with softer PU (I think 80A). Probably because the MAD hubs have 15mm PU thickness. Anyhow what matter is that I feel way less the bad roads. If I need to rate the difference I would say 3 times better compare to the other hubs (they are not famous for ride smoothness ). Of course full urethane will always be better in absorbing vibrations, but I can really live with that with these hubs.

  • Power output. Both from riding feelings and telemetry data the MAD hubs are more powerful than the others. They easy output 1800watt (total from 2 hubs) compare to 1200-1300 watt of the DIYEboard hubs on hard acceleration. Although I could reach up to 1600watt few times on hard acceleration up hills. Of course the two hubs have different Kv, so would have been better to use the same Kv for both the motors. Anyhow overall the DIYEboard wins over the MAD 130Kv hubs for the takeoff up to let’s say 10-15kmh (this DIYEboard 75Kv surprise everyone for the instant torque). So let say in a drag race, after the first 15 meters there is no chance anymore for the DIYEboard ones, really no game. Don’t get me wrong the MAD hubs pull too, it’s just that the motors are let say less efficient at really low rpm compare to 75Kv hubs. If you want instant torque, for an overall lower speed I am sure the MAD 75Kv version will be a blast. I would be really curious to try them out! Nevertheless I could climb all the hills in my city with no problem at all (more about hill climbing here

  • Top speed. What to say…they fly, that’s it. Fun fact, to understand how much they can pull is that I never reach 95% of duty with these motors. Before I used to pull the throttle all the way up and you see from the telemetry the duty at 95% and then the motors amp, speed ecc increasing over time. With these motors I can reach at most 70-80% afterward my VESC setting limits the power. When you ride you do not feel it at all, but basically I easy reach all the battery and motor max limits. With that being said +50kmh easy, too easy maybe. Probably a bigger LiIon battery (10s4p or above, 12s…) or Lipo are better if you want release all the power. I think it’s already plenty though :rofl:.


  • VESC temperature. This is actually the only issue I have experienced with them compare to the DIYEboard hubs. I guess is due to the difference in power and current drain. Of course depends how you ride, but if I do it hard the VESC temperature rises fast on my Maytech’s VESC. This can be solved limiting the max motor and battery settings. Basically to reduce the peak currents, but still keep nice top speed.


A real heatsink , better VESC, or 12s will probably help too. Don’t get me wrong I use it every day, I don’t ride all the time at plus 50kmh :smile:. With 30Kmh average and some sprints not problem.

  • Battery drain. Same story, they ask more, if you push hard they drain more. Not surprise by that. Again if you ride in a more enjoyable way, same range of the others.

Conclusions: I really like the MAD hubs and I am happy with them. I will definitely choose them over the DIYEboard ones. Which versions to choose? Good question, I guess if you plan to climb hills all the time the 75Kv is recommended. Unfortunately I couldn’t test it, but I guess they are the same motors, maybe even the only different between them is the delta and wye configuration, so you can always switch between them (130Kv / 1.73 = 75Kv). On the other hand if you want to have a freaking top speed and overall great power, than go for the 130Kv version, as I did. Of course, keep in mind the max ERPM limit of the 4.12 VESC. With a 130Kv you are at the limit with a 10s, out with a 12s. You can always limit the max ERPM in the VESC setting and moreover the only problem is during bench test, otherwise you need to go over 70kmh to encounter this problem! To make it short, don’t spin it fast on bench .:laughing:


Hi guys. The review is out check it out! I would like to close the group buy this week, so I would ask everyone who already signed to confirm or not your wishes . Of course you can remove your name from the list, but please let me know otherwise we wait forever :wink: For the ones that wants to join please fill or refill the new form below. After the GB ends I will ask a first transfer to buy the motors only, and then a second one for the shipping costs and additional optional work on the motors since this part is more subjective.

Here the new Google form where I only need your username / How many and which Kv for the motors / the spare PU you want.

Yeah… thx Ray :wink:

Red this topic last night all drooling about the 130kV hubs that Rey has been shredding hard lately, felt kinda conflicted with my still-coming 35kph board and those 50kph speeds here but then I recalled I had an experiemntal idea to, well to cast my own normal wheels anyway, but had an experiemantal idea to take a mould from similar but bigger 115mm or so offroad/smooth RC car wheels instead with what extra size I could get the same speeds, but would the torque curve be similiar for 65kV’s like Ray described the 130s to be? I mean they probably have same much copper beef, same price range and also same many poles, they (Maytech) have 65kV and 130kV hubs Both available. Anyhow, just a night itch, a showerthought that maybe we 65kV fellas could get best of both worlds, so do speak, altho with hideous big wheels. tho they roll better over stuff<:P

If you are going to make bigger wheels for sure stay in the range 75Kv range is better. You will gain speed but still having nice torque. Of course the torque is gonna decrease. I couldn’t try these hub motors is 75Kv configuration. I contacted people that used it in 10s and 12s and they say that are really really strong. I believe it since mine are already crazy

Ul-la-laa. definitely gonna do a test ‘drag’ race if because the MADs and Maytechs are same price range and people are just Moaning over to find out what’s best in these cheaper kind of brands. Oh hey jajaa: If I get my board ready I’ll do the very same screen layover test ride, and we can compare, I think

That would be awesome. I am waiting for the other guys to confirm and I will close the group buy. I hope it’s gonna make it. I know that most of the people don’t care too much about hub motors, but if you like the stealth look and sound is a problem for you (catching attention from Police) then hub are perfect. I tried belt drive system and these how I called Mad hubs really go strong really strong. They are in the same price range of Maytech because come from the factory. The real retail price was double

so they come ready fit to the board? iv a 10s4p 30q battery which would you go for 75 or 130kv? and how much in total ?
