Re: Do some motors have more/less torque with the same power levels?

Thanks, just ordered a 4 kw cyclone. Probably overkill but I'm sick of my motor overheating on hills and any speed above 30 lmao. At 60v and 80 amps it shouldn't be too stressed and especially since I'm going to install a temp sensor too, thing should be bulletproof (atleast hopefully) lol, so you ...

Re: Do some motors have more/less torque with the same power levels?

Sure, run a 2-4kW motor at 5kW. What could possibly go wrong? I wonder why they rated it 2-4kW? 1680w* This isn't even the 3 kw cyclone. To its credit though, it lasted over 800 miles of my abuse, and there are quite a few hills around here too. It probably would be a good reliable motor as long as...

Re: Do some motors have more/less torque with the same power levels?

I'm sure the controller was extremely lossy on the smaller motor though XD. I replaced the stock 40 amp controller with an 80 amp one and was running it at 60v, so quite a lot of power for a small 1680w motor. Can't imagine it being efficient at all. This is the controller I plan to use on the new ...

Alright, I emailed him, very reasonable guy. He gave me $45 off shipping which is satisfactory enough to me. Thanks everyone!

Re: Do some motors have more/less torque with the same power levels?

Unfortunately I have no clue what the specs for the motors are. Couldn't find it in the simulator either :( I am after reliability though, so less overheating for sure. I like the amount of power and range I have. More top end would be nice, but 45 mph on an e bike is already more than enough for m...

Re: Do some motors have more/less torque with the same power levels?

Okay this makes perfect sense thank you :) I'm guessing I should expect a small power increase though with a larger motor because it'll be more efficient than the lesser motor right? Less power goes to heat and instead into the wheel where it's supposed to go? Probably a small difference though. No...

Email paco and ask if you can combine shipping- he’s pretty reasonable on this. But they aren’t light!
Does Paco work for cyclone taiwan? Would I be able to contact him through the website?

Cheapest prices for Cyclone 3000w/4000w?

I need a new motor and was thrilled when I saw the prices for the cyclone 3 kw and the cyclone 4 kw on cyclone taiwan, UNTIL I added it to my cart and saw shipping was $140?!?! I see sick bike parts selling the cyclone 3000 for $250 and their shipping is MUCH cheaper than cyclone taiwan, but I reall...

Re: Do some motors have more/less torque with the same power levels?

So it's as I thought then. If they are geared to the same max speed (meaning the winding is irrelevant, right?) and powered with the same controller, they should have the same performance, unless one motor is more efficient than the other. In which case the more efficient motor will have better per...

Re: Do some motors have more/less torque with the same power levels?

If I use the same power motor controller on the cyclone 3000 as I did on the mini, and I gear it to have the same top speed in each gear as my mini, why would the cyclone 3000 have more torque? Where does that extra torque even come from? It wouldn't. Torque is a function of torque constant (Kt) in...

Re: Did I blow a fet?

running 4 kw bursts through a motor rated for 1680w, :o That's quite a lot of power. I burnt up a motor as well doing something similar, 150 phase amps into a motor only rated for ~40 continuous. By the end of a 15 minute ride it was smoking. An alternative to upgrading to a beefier motor is to use...

Do some motors have more/less torque with the same power levels?

I'm shopping for a new motor and I'm quite confused on the amount of torque a motor has. In my case, my old motor was a mini cyclone or cyclone 1680w and I'm looking to upgrade to the 3 kw cyclone. I keep hearing that the cyclone 3000 has a lot more torque. If I use the same power motor controller o...

Re: Did I blow a fet?

That's more burnt than my hubmotor was when it gave up the ghost. Given that a phase wire has come loose (melted off), the temperature inside the motor got at least hot enough to melt solder, likely higher. Your motor is definitely toast. Aw that's too bad. Not surprised though as I was well above ...

is my motor toast?

A couple days ago the cyclone motor on my e bike just stopped working after I flogged it pretty hard up a hill. I just assumed it was a hall sensor, but I pulled it apart today and saw a phase wire had broken off. Giving it a closer look, I saw this. https://drive.google.com/file/d/19JBRKKLxnwkydDXQ...

Re: Did I blow a fet?

Take an ohmmeter and measure between each phase and battery + Do the same thing between each phase and battery - If any of the measurements are noticeably lower than the rest (often near zero), you most likely have a bad FET. Based on your description of the problem I doubt that it's a blown FET. B...

Or the battery pack failed, if not the BMS (if any) then cells themselves
I have a cycle analyst connected and the voltage read out, etc. looks normal. Just the throttle is unresponsive. I'm assuming if it's the bms, the battery wouldn't power anything at all including the cycle analyst?

Is it a direct drive or geared motor? Could be a cooked motor, open the side covers and you'll smell if but do look at the windings. A dark color could mean its cooked.

I was riding my e bike today at about 35 mph up a slight hill (max it's capable of on a flat is 47 so I was pushing it a little bit) and felt the power decrease very suddenly and then the throttle became completely unresponsive. I shut the bike off and restarted it. The throttle worked for about fiv...

Really not sure why 60 mph would be a big deal on e bikes if non motorized bicyclists hit those speeds regularly downhill on stock bikes?

Re: Can anyone help me wire a brake light onto my e bike?

The light you bought on Amazon will have one wire as a common ground. The other two wires will be the positive 12V+ lead for tail light and the other for a brighter brake light. Test your assumptions on a car battery. Then only the light is at risk.... Not enough to go much further. The brake lever...
