Hi guys I have been experimenting with greenewheels bike some things you may want to know. motor is similar to but doesn't appear to be a bafang (gears are different as is the housing) bafang make several models though I have successfully overvolted the standard controller to 55v nominal (63v...

Guys, thanks for the quick reply I have upgraded the 50v filter caps with 63v on the controller I am playing with ( have been running the 50v caps for several weeks now using 50v lipos with no problem) I was unaware of the 4110 fets and did not think the Rds resistance was that critical, but...

This is for all you tech heads and tinkerers out there Can someone give me some advice? I have a small chinese controller for my brushless bafang motor, it uses only 2 fets per phase rated at 60v 60a, originally designed for 36v 15a. I have been able to use 44.4v lipos at 16amps peak current...

A note to Knuckles question about the disc brake setup motor as supplied has been machined to accept direct bolt on for a standard disc if you want the specs email Keywin (ecrazyman) about it the caliper is standard on this bike and was not modified in any way, the only thing I had to do is shim...

Thanks for the info Fletch, that makes sense, the ecrazyman controller is rated at 30amp and under testing hit a max of 25amps, unfortunately my 4ah pack is very stressed at these loads and the voltage sags below the controllers cutoff limit after a few seconds. My current controller is rated at...

Hi guys, in answer to your questions, using 12s 44.4v lipo pack only, look at the pics the small bag under the seat is the batteries, gets min 15km at around 30 to 35km/hr still need assistance up hills but not a lot! I know it's not the most powerful ebike around but I like to pedal a little...

Just finished my 1st build and am very happy with result, Great full suspension giant bike with hyd disc brakes front and rear. Bafang geared rear hub motor with 5speed cluster. All under 20kg with Battries included I have been riding a chinese import with similar bafang motor powered by 36v...

OK SUCCESS I have bumped up the voltage on my Greenwheels (aka bafang motor) Bike the controller supplied is the weak point and limits the voltage and current capablities!(rated at 36v 15a) I am using 12s lipo pack 4ah which may sound small but given it's 10c rating is proving to be a great...

Hi Guys saw this thread a bit late, I have one of these greenwheels machines, good bit of kit for the money, everything works well out of the box. As I am also here in Australia with it's 200w limits hmmmm. firstly on power output of these machines, if you assume 90+% efficiency 36v x 15amps =...

Hey thanks for the advice guys have ordered a 48v ecrazyman controller as a backup incase I damage the original, after I test the new controller I will attempt the mods to the original controller will post the result

Hi guys ok I have read previous posts about ecrazyman controller mods I have a ebike with geared brushless motor like bafang I think, 36v10ah lion pack and standard controller.Want to use 48v battery, opened up controller(pic below) main filter caps rated 470uf 50v and Fets are p65NF06 (rated to...

Hi Richard, thanks for the info, photos of my motor is attached if anybody can recognise it?? I am checking for suitable packs on ebay Australia, seem to only be 7.4v available here. have ordered a 48v controller from ecrazyman. but will check mine out also will start with around 48v first and...

Hi guys been following this thread with great interest, I also have a small geared brushless hub motor (not sure if it is a bafang but it looks very similar) with 36v 10ah lion battery and am looking at ways of getting more power out of it. I too only do a short commute to work and home of...

Hi guys I have a 36v 10ah lion pack driving small brushless geared hub, not sure of the brand. looking for a little more top end speed and torque for hills. Existing controller is marked as 36v 16A max, Have looked at upgrading to a 20+ Amp model 36 to 48v, my questions have to do with the...
