    1000W hub motor options

    Update: So I added some grease to the Bafang. Whoever assembled the motor managed to get grease everywhere except for the gear teeth! The grease quietened it a bit. Also I've ordered a MXUS DD motor, so I'll switch to that in future. Thanks for all the advice.

    1000W hub motor options

    Yes, I have a Grin sinewave controller to swap in, hopefully that will also help. Sorry, not a chance I am using ATF!! I've done that before, and the mess it made was diabolical.

    1000W hub motor options

    Thanks for the replies. Dan, I'm glad you mentioned the coasting limitation of a DD motor, I'd forgotten about that. Regarding the number of turns, could you please check my calc for the RPM per volt of the Code 10 Bafang is correct? Code 10 = 300 rpm (link) @ 36 volts ............. = 8.3 rpm...

    1000W hub motor options

    Hi. Could I please get some advice about upgrading my hub motor? Surprisingly, it's not because I am chasing more power! My current Bafang BPM has enough power but it's pretty whiney, so I'm hoping for something quieter. Any suggestions please? Perhaps an eZee 250/350? Or a GrinHub? A key...

    Australian supplier for hub motors

    Hi, I'm after a replacement geared hub motor, preferably a 36v500W code 10 Bafang so that it's a plug-n-play swap. Any recommend suppliers in Australia please? Does anyone have experience with Ballarat Electric Bikes? Thanks.

    Yeah it's a tricky one to chase down. Congrats on getting it sorted.

    motor cutting out over bumps

    Thanks. I wish I had a proper workshop! :? Instead, I had to rig up something dodgy in my living room, taking care not to scorch the carpet when dropping the spinning wheel onto the floor :oops: Anyway, despite sounding and feeling like a mechanical problem, I think you guys were correct...

    Cool, I'll check over the wiring carefully. Thanks for the replies.

    motor cutting out over bumps

    Hi, My Bafang hub motor has started cutting out for an instant over even the smallest bumps (such as the joint between concrete pavers). It then cuts back in immediately, sending a jolt through the bike. Has anyone else had this problem? Or can suggest a likely cause? Thanks.

    EM3ev MAC 50 volt kit with battery

    +1 My experience isn't with these guys, but anyway I had a bit of a saga keeping the wheel true. Turned out it was due to weak spokes that were laced incorrectly. If I'd got the LBS to fix these problems while I was building the bike, it would have saved a lot of hassle.

    Just another awesome commuter e-bike: rear hub BPM, LiPo

    Time for a quick "20 month review", I reckon. So... most importantly, the desire to ride is showing no signs of wear. :mrgreen: Onto more mechanical matters, the axle in the hub motor snapped in half a couple of months ago. The Bafang wasn't really to blame, there are some unavoidable savage...

    Just another awesome commuter e-bike: rear hub BPM, LiPo

    Ahhh very interesting. I'll try this out next time the wheel goes wobbly. When wiring up the new motor last night, I got foiled by the old "swap the yellow and green wires from the motor to the controller" trick :oops: And it was after I had the wires all nicely cut to length :evil:

    Thanks for the info. Are you saying that 2mm spokes are better than 3mm? How does that work??

    Just another awesome commuter e-bike: rear hub BPM, LiPo

    The axle in the Bafang motor has snapped :cry: It lasted 18 months @ approx 70km per week. I can post some photos if anyone is interested, but it's a bit hard to work out what's going on without wiggling it around. Anyway, hopefully it doesn't take long to get the spare motor up and running...

    EM3ev MAC 50 volt kit with battery

    It's always frustrating that some companies respond immediately when you are a potential customer, but once they've got your money suddenly they're nowhere to be found :roll:

    EM3ev MAC 50 volt kit with battery

    Another friend has been bitten by the e-bike bug! This means that kabbage's Avanti commuter now has at least 7 indirect offspring. :D While they're all rear geared hub mountain bikes, there's quite a range of approaches used. This latest one uses the EM3ev kit (MAC50V1KWLTBAT), the most unique...

    bafang hub motor getting noisy

    Nope. I was keen to isolate whether the noise was the gearing or not, so the bearings were going to be stage 2.

    bafang hub motor getting noisy

    In the past, my ham-fisted struggling has put the wheel out of true each time. But this time the wheel stayed straight. :D More good news, the new clutch and gears (back to grease) have reduced the noise a bit. Maybe a touch louder under load, with a pulsing sound, a bit like dragging brakes...

    bafang hub motor getting noisy

    Thanks for the replies. Sorry if the questions about re-greasing the motor seems like I'm being overly precious! It's because every time I pull the motor apart, the wheel somehow ends up needing to go to the shop to get trued. So I'm keen to do it right the first time. I'm wondering how thick...

    bafang hub motor getting noisy

    No sealant. Anywhere. Yeah, if I went to a bit of effort, maybe I could get it sealed. But I really hate dealing with ATF and the replacement gears are cheap enough, so I'm abandoning the whole ATF experiement!

    bafang hub motor getting noisy

    The new clutch and gear assembly has just arrived, so I'm about to swap in the new one and revert to grease. Very much looking forward to the rear of my bike being no longer covered in a thin sheen of oil. Any tips on how thick to lay it on and how to get the best coverage please? I bought a...
