9C 2812 hub motor review

Greetings Sunny of 9C China was good enough to ship me a single 9C 2812 earlier this year so I wanted to post a few comments, there are threads already on this motor but not for a while. Sunny mentioned he'd accept orders minimum 10. Not so easy to buy this very slow winding I couldn't find anyone i...

Re: 10k+ miles ebike tour - Africa, Capetown to AddisAbbeba

Patrick One factor covered in detail on other threads is wind resistance so as to really cut down your cruising energy consumption. It is possible to configure a very aerodynamic kind of machine that you could then enhance with minimal electric assist. But I'm not sure if anyone here has actually do...

Re: 4500+ Miles US Ebike Tour - August 2014

A high bar. Your point of no return is at the 1,175 mark right?. Assess then if you want to give it a shot and if not turn back in order to complete a more leisurely 2,250 mile shakedown tour and try again next year. it sounds like you need to be back for work so no margin if you are running behind ...

Re: 2812 9 continent motor in 26" wheel

Hi - reading this I'd like a 2812 for a high voltage setup. Does anyone know the loaded/unloaded rpm? Might make it clearer as it looks like I would have to buy it from another country or maybe direct from 9C. Their item number is RH205 I know the values of the 2812 is 180/280rpm so am guessing the ...

Re: 9C 2810 on Ebikes.ca Simulator

I have run the 2810 on 74v for a couple of years with no issue. I set the CA to max amp draw of 24amps so around 1800/1900 watts peak and no issues with overheating, it runs just the same now as it did at the beginning. It runs very smoothly at 10S and ample power/torque for most purposes. this moto...

Re: Touring Hub Motor and Battery Choices

No telling what the standard for breakers is south of the border, on that I'm clueless. But even in the USA, circuits are not one breaker one plug. Lots of things share a circuit, and typically only kitchens have 20 amps. Two bedrooms might share a 15 amp circuit. In a motel, south of the border, y...

Re: Touring Hub Motor and Battery Choices

FWIW, EM3 ev shows some slower windings of his muxus dd motor on the website. Waiting for a reply from him on what exactly he has, but looks like one of them is the very hard to find 2810. If so, at 48v it will max out at 20 mph, and loaded down with 40 pounds of ping, more like 18. 4 chargers eh, ...

Re: Touring Hub Motor and Battery Choices

Sounds like a nice simple and lightweight setup. What kind of weight are you pulling? I was thinking of using an extrawheel trailer instead of the bob Yak, have you ever used one? I've read it is lighter, easier to attach and detach, but instead of one big bag in the Yak you use two regular size pan...

Re: Touring Hub Motor and Battery Choices

Thanks for all the advice. Definitely needs some sensible planning and equipment! A couple of short "test" tours would probably be a good idea too. I kind of think people can do it different ways and make it work, for me I am clear on my speeds and distances I want to do, the amount of energy I have...

Re: overwhelmed newbie

Consider a slow wind direct drive motor such as a 9t from cellman emv, which will get you 23/24mph at 48v. Quiet and will last long time without maintenance. It comes with matched controller, on/off switch, and throttle/cruise control and CA also. A Ping battery is a sensible investment for long ter...
