If I was to go with a mid-drive, I'd probably spend the big bucks and pick a liquid-cooled Motenergy motor, the ME1616 looks pretty appealing. It's pretty big and heavy for my frame, but honestly go big or go home. If I'm going through the trouble of creating a mount for a mid-drive, I may as...

Alright, I'll have to find a better option then. I'd like to stick with a hub motor setup because my frame doesn't easily support a mid-drive motor, especially without a welder. Do you have any suggestions for powerful (at least 6kW continuous) hub motors that can run pretty fast (over 900 RPM)...

I decided to keep it simple with my questioning, since there is likely a language barrier for the Cyclone company to overcome. It seems they decided to keep it quite simple with their answer as well. As you can see, they claim a 21.6kW continuous output, which I'm not sure if I believe. However...

Thanks for the answer, I just emailed them and asked about it. I did manage to find this on the website: It claims the "6k hub" is capable of 20kW peak power, and mentions the "nominal capacity" of the battery is 6kW. I'm sure they probably meant 6kWh, considering they list 120V & 50Ah battery...

I'm planning on using the 20kW Cyclone hub motor (http://www.cyclone-tw.com/motor.html) on a dirt bike build I'm working on, but are there actually any specs someone can provide me with? I haven't really been able to figure out much info on it. All I know is that they offer it with a 120V...

Sorry, I'm not very experienced.

Good point, although for more range I'd like to have an "eco" setting that limits it to something like 72V and 50A or something, which would be a big improvement. Still not much though.

The reason I chose the cell in the example is because of it's claimed ability to support a 35A continuous draw, meaning I'd need less of them in parallel to support my system (or more in parallel for a safer battery). As for additional hardware, cost isn't a big problem, it's just the fact that...

With the Samsung 20S, I would need 198 cells (33S 6P) which I'm finding for just beneath $850. Only 1.4kWh for the pack, but I can probably accept that for the price. I'll keep looking though. Thanks for the advice about 18650s, I wanted to use them at first but for some reason determined the...

Currently I am making a small, lightweight, sporty electric motorcycle, and am planning on using the 20kW cyclone hub motor. I'm aware that the 20kW is the peak power, but I still think it's a good choice for it's price. The only problem is the batteries; I'd like to make my own custom battery...

I suppose I definitely am not looking in the right place then. On another note, if you were to run a liquid cooled motor with a powerful water pump that circulates ice cold coolant through the motor at a sufficient rate, is it theoretically possible to crank up the volts and amps a really...

I'm new here, but have been on this site before for information on EV conversions and such, due to an electric conversion for my 1979 Puch Maxi Sport. The goal is a 12kW hub motor, 6kWh battery pack, custom carbon frame and swingarm, full motorcycle suspension, and full electronics/features to...
