Re: A healthy diet will help us prosper in this pandemic

The study doesn't actually show that. Here is the full text:

This research did not make a conclusion ( just an association ) and it even included people who ate red meat into the 'plant based' category. :lol:

DD is honestly not suited for this application. It will be needlessly heavy!

Just get a geared hubbie and call it a Day!
Those will burn up even quicker in the wrong situation because they also perform poorly at super low RPM.

let the ebikes.ca motor simulator be your guide to this.

Re: The ideal hubmotor

To me the ideal hub hub is either: 9C design with 0.27mm laminations and the flattest and tightest windings possible - this could produce a peak of 93% efficiency at best, while also dropping the weight of the motor. Add a cooling solution and this gets even better. Large-ish dual stage geared motor...

Re: Low Speed, High Torque Hub Motor?

Any hub motor would struggle at those speeds if the load was very high, ie you are climbing a hill all day. The magic pie and ASI hub motor would be the best choices here. They have the highest pole counts of any DD hub. Also using a smaller wheel ( 20" or less ) would increase the low end cont...

Re: Help decide between All-Axle and GMAC

I'd say 'all axle' motor all day, except it does not come in a rear motor configuration, which is the right place to have a motor on a majority of bikes. The GMAC is a nice motor; they managed to drop 1lb off an already weight to power optimized design. Except being a geared motor, you'll never see ...

Re: Why do I now ride my ebike with light motorcycle gear?

Bicycling is simply not that dangerous a thing to do. When you wear a helmet, you are supporting a pro-car, anti-cycling propaganda campaign that's older than any of us.

Ok, back from the bike shop. They're fitting new bearings to the new swingarm.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Get the freewheel model. It has 14mm axles on both sides. Unless i've missed a change somewhere.

Because of the nutty power this motor can put out ( roughly equal to the bigass crystalytes of yore ), you very much want the biggest axles you can get if you're in the 3kW and beyond club like me.
