    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.

    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

    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

    Hi folks, After almost a year of e-bike goodness, the BPM geared 36V500W hub motor is getting noisier. Under load, the whine is louder these days, especially above 30 km/h. I am running it at 44v and 30A. The plan is to pull it apart to hopefully find the cause. What should I be looking for...

    my experience running LiPo on a commuter bike

    After about 6 months running LiPo on my commuter setup, I’ve just replaced a pack which copped the brunt of my noob mistakes. So I thought I’d share my experience, in case it is useful for others trying to decide which chemistry to use. Running 12S Zippy packs, my commute uses 2Ah out of the...

    Dillenger Conversion Kit 1000W 48V REAR 26' Li-Ion Battery

    Warning: e-bikes are contagious! Having been infected by a member here, now I have passed it on to someone myself. He bought a Dillenger conversion kit off Ebay, and today we had a showdown between it and my 44v LiPo commuter. It's a comprehensive kit (including battery), the only thing...

    noob help please- LiPo 12S 4000mAh protection/charging

    Hi, A couple of noob questions please (sorry if they've been covered already) - if I have a balancing charger, is monitoring pack voltage with a Cycle Analyst enough info to prevent over-discharge? Or should I also be monitoring cell voltages as I ride? - to charge 4x 4000mAh 6S LiPo's...

    I'm a noob and I wanna go sensible speeds reliably

    Hi Endless Sphere, Preaching to the converted I recently borrowed an e-bike and, wow, you folks sure are onto something! It is the best form of transport I have ever used, quicker and cheaper than public transport. And, around the inner city, it is actually quicker than a car. Incredible! So...
