My Neo cross has a 20 amp controller.and I tried with an s09p controller It worked great at low speed.But I couldnt get more than 18-19 kmh with a 48 volt battery.Torque was fantastic.So the controller did not work like it should with the Dapu motor.The motor is buildt like a mac motor I...

Thanks,Very nice explaination

I talk from practical experience ,my neo cross have never been to hot.In Norway on the west coast there is a lot of mountains.So my rides are VERY steep and long.I have compared the Dapu motor with a 500w bafang cst a 250w cst and a BPM 500w motor code 13. I used the same controller s09p on...

Why do you think the Dapu motor is the same as XFC07? The dapu M155 motor is the same as the Motor in the newer Bh emotion neo cross:It is buildt like a mac motor and takes a LOT to get hot.I am 100kg and have been up some very long and steep off road hills.The motor never gets hot,But I belive...

I have seen the Focus reviews.You should have a look at pedelecforum.de yourself I dont understand your argument.The new Kalkhoff battery does not look good,It doesnt make it look any better just because you was able to find an even uglier bike to compare it with

I have had my neo cross for 2.5 years now.used it almost on daily basis.Very happy with the bike.Only one problem but I had no problem with warranty here in Norway.The problem was water inside the lcd display.Otherwise the bike performs as when it was new.Spokes are thight and no problem with...

You should at least know the correct information about your products.The new Evo motor has 80nm max torque not100nm.And from reading on pedelecforum.de it is not very quiet.And the prefered motors seems to be yamaha or Bosch performance:the new 75 nm version I belive will outperform everything...

The 2016 mod have 75 nm torque.The motor is the same i belive.Anybody know if there will be a firmware update for the older performance motor up to 75 nm?

This is from endlessphere: I've gotta couple 201RPM Q128H, 700c wheels running 16S RC Lipo (59-67V). Top speed about 22-24MPH off the charger. I dunno anything about laminations or efficiency ratings but they climb like mad on 900W peak controller power. In service for nearly a year - windings...

The Xiongda is fantastic when it works.But in my opinion the motor should be rebuildt.And maybe by another company like pansonic for example.Then it would be perfect.My last motor was quiet for about one week,before the growling sound came.It is still reasonable quiet in high gear with little...

Thanks for the info D8veh.I have also been curious about this motor for a long time.How is the hill climbing compared to Xiongda 48v in low speed gear.And will it overheat on long steep hills with a 100kg rider?

Yes,I dont understand why not every hub motor is 48v,it is only benefits with a 48v system

Thanks,I have seen this one.I want a bigger controller than 15a so its not what I am looking for.But I wouldnt automatically trust the description.

I have wantet to try the Q128H for a long time,but the motor is already bought on ebay: http://www.ebay.com/itm/Bafang-8-Fun-E-Bike-BPM-Motor-36-Volt-inkl-Schraubkranz-9-Fach-gebraucht-/271815610515?pt=LH_DefaultDomain_77&hash=item3f49791093

Forget about it,I must have been reading wrong.I couldnt find the post again.Are there no batterys with an internal sensorless controller?

I read on endlessphere that s06s controller could run sensorles.If thats true.Can I use a bafang Bpm 2 sensorless motor with one of the new bottle batterys from BMS Battery with an internal sinewave controller?

I dont think there is a heath sensor that protects the motor for oerheathing. .people have burned their bafang bbs

I had the same problem with two bosch batterys.It was caused by condense.The bms is very sensitive to condense.The first battery never worked again.The second started working again by itself.Now I am very careful to not expose it to big temperature changes.Especially when charging.
