What is up RU-vid World .My Name is Blue. I been Ebiking for 7 years and counting,started 3 years ago video recording my rides.But I build e-bikes and batteries for them. E-bike everything is how I see it…I also ride my e-bike everyday around my city here Lakeland FL. U can reach me at email alonzoharris347@gmail.com
There are plenty of situations where a 3k can actually run faster than a 5k. But on the flip side of that the 3k can never physically go as fast of a top speed as the 5k. The bigger windings require more power to run and can dissipate more amps. So there are several situations where you are better off with the 3k. If your controller is undersized then for sure the 3k would do better. If the controller is sized right and it's still not doing the business then you probably need to upsize your power wires or crank up the amps in the Fardriver. When you go to the 5k you really need to be at 72v or higher. 48 or 52 are not going to get it done. The higher the h size the more power you need to get the performance you want. The h rating is written right on the motor WP40H and 50 for sure are the most common but I think they do 60 and 70 in a 205 also. They go up to 90h in a 268.Those are some very wide magnets. That's the real wide smaller diameter wheel. I was thinking about getting one but at the moment I'm still enjoying the 8k 273. Definitely not bored yet. Still holding on for my life. Oh yeahhhh.
Look at you stopping at lights! Lol when I am on my bike the laws go right out the window! I have ran from most the cops in town and now they know there’s no chance in hell catching me! Lol so they stopped trying!
205 and 273...260 I think. Those should be the bigger ones. I don't think a 268 would be right on a MTB even if you could shoehorn it in there. The real big motors require torque plates, especially if you use regen. I had to double up on mine. A 273 can chew dropouts like bubblegum. The torque plates they include with motors are aluminum so they are absolutely useless. I don't understand their thinking. Aluminum vs a hardened steel axle...I wonder which will give first...said no one.
@@sweatcoinhelper4602 the h rating defines the width of the magnets. Higher number equals wider. Like WP40H means wider. Qs273 they call a 10" even though it's almost 11. QS205 is 8" diameter. The higher the h number the more power it takes to make an erpm. If you had a 72360 and you switched from 3k to 5k you would have most likely have made your bike slower. If you don't need to go over 55 or go long distances at full speed a 3k is a much better choice. More copper gives you higher erpm but you have to feed it like a big cat and not a house cat. Not that house cats are slow. A motor is a giant inductor but it's resistance is what governs it's efficiency. If you just want torque you are much better off adding a second hub motor up front. People think 2 motors sucks down the battery but they a wrong. Unless you are going crazy slow or sitting still 2 motors and 2 controllers is more efficient. When you put 2 resistors in parallel it halves the value of the resistor and doubles it's ampacity. So basically it is like have a motor twice the size but with half the resistance. That is more efficient. Common misconception. Many a channel spreading incorrect information. If you use more power with 2 motors it's because you are enjoying the even more powerful torque than you had. Time you enjoyed wasting wasn't wasted..blah blah blah
5000watt hardtail? Motor isnt all that sucks. The chinese lie. Get used to it. I saw the black hand and knew nothing useful would be said. I was right.
@@ebbikerides8608 Push your bike forward and apply the front brake only and look at the give in the forks back towards the frame. I have the same bike with a 1500w on it. I have hydraulic on the back only.
If you put hydraulic on the front the fork will collapse when applying the brakes. You need to upgrade the forks if you're going to upgrade the brakes.
Yep the same motor I got on a 20 inch fat tire bike and I can only get it up to 58 running 200 amps and 400 phase! Lol makes for a good trail riding motor! Need to get me the qs273 for the streets!
205 is 3kw nominal. Peaks at 6kw but only for few seconds. What you got seems to be a 205 v1 which is a cheaper lighter version for budget ebikes, v3ti is better quality materials yet not the right size for that frame, what you wanted is a 205 v3 for motocycles, it's 3kw nominal but peaks at 14kw... The orange wire you mention is the v4 cable, still not right size for that fat bike. Better luck next time❤ There's no 5kw nominal motor from QS. It ranges between 1000, 1200, 3000, 4000 and 8kw up to 25kw nominal for competitions
Wicked blast blue that thing is still moving fast but I can see why your not happy with that motor because you are getting similar speeds with your 3000w just had my first blast on my 3000w and I'm only getting 52 but still buzzing 😆 man 72v hits different my wires going from the battery to the controller are getting hot but the motor staying cool think I need a battery with 80bms instead of 60bms and bigger controller then I will hit 60 I've also noticed with electric bikes that 80%to 100 % throttle does absolutely nothing and when your going fast you can kinda feel that sweet spot by backing off the throttle a little you probably know what I mean
When you say phase you mean hall I'm assuming. Did you weigh the motor? That's how you tell how many watts it is. The 3000 and 5000 are the same outer shell but the 5000 has more copper. NBPower sells QSMotors sir. All warranties are directed to QS. Fardriver is also QS. So Fardrivers are not good. One of mine was kicking 27v out to the halls when moving and 7v when sitting still. So did rerun motor setup when you swapped from 3000 to 5000 or which bike or whatever, sorry I've been busy turning my bike into a 100mph beast so I'm behind on your shenanigans at the moment. Give me your specs and stuff and go over your wires one more time and if it's a Fardriver make sure it's in high gear.use the little blue plug that bridges across the 3spreed and keeps it in high. Most controller give you high gear by default but these Fardrivers give you medium speed. I hate the orange wires on these new ones. Ugly. That 273 is a big ass motor inside a 20" fat rim.i had cut my own spokes and roll the threads in because I couldn't find anyone that sells them under 40mm.. I see why, you can't fit a normal spoke wrench between the tiny gap . What controller are you using. The 5k will be slower than the 3k if you aren't giving it enough power. It takes more power to push the heavier motor but you get a higher top end. If you bought the 5t instead of the 3.5 or 4 or whatever they are offering it will be a slower motor. 3.5 is the fast motor, 5 is the torquer one. More turns is more torque and than also means it can handle more amps. I had some AliExpress vendor try to jerk me around but fortunately I had ordered a second 273 from Amazon or I would still be waiting. I think I actually got a better price on Amazon which makes no sense at all Motor not engine. I can weigh my 3000w for you. I think it's about 30 pounds. QS273 weighs in at 39.5 pounds for just the hub. 1500w QSMotors are 18-19 pounds for the hub only. Let me know what I can do to help you man. You can always bring it down to Sarasota if you want a second opinion. I highly recommend check your wiring over again, 9 out of 10 times it's a stupid loose wire. Even on a brand new controller I've had bad connections inside that 30 pin or whatever it is Fardriver harness. 27v my 680 was sending to the halls and I have 360 that was doing the same thing. My Razor has been down for a good month. Both motors need attention but I haven't had time due you my 273 quest and just setup a new giant 3d printer tonight so I'll probably be printing a wheel insert for the 273 later. I'm already using it but I haven't balanced the wheel yet. Motorcycle tire weighs almost 20 pounds compared to the 5-6 pounds of the Ultraverse tires. I have a doctor's scale so I've been weighing all this stuff. I'm very curious about the weight of your 5k qs205 vs my 3k qs205. I've got mine handy with just a 20 inch rim on it and tires and tubes I can throw on the scale. Give me a weight and what you have there and I'll give you my numbers at this end.
I think when I was hunting down the hall issue with the 27v it was a ground issue. 2 different Fardriver controllers were doing it. None of my other controllers have ever done that. I fix controllers on a regular basis there is no time when that 5v line to halls should be unregulated and kicking out higher voltages. Good hall sensors can usually handle 24v or so, somr as high as 30. My halls didn't get cooked on my 273 but now I'm thinking they may have gotten damaged to some extent,, maybe I'll switch to the other set. I basically just stopped using the 72680 until I do further testing. My VESC is a big one anyway and the software tuning is far superior. Bring that's in actual English is a major plus too. lol Qs owns Fardriver, there was even a little leaflet in the Fardriver box. I'm sure they are NBPower also.
@@ebbikerides8608You still don't have hydraulic brakes? What? I haven't been around for quite a while too. It's only like $100, probably less. I think Bucklos, Zoom, and Shimano all have options available for cheap. All 3 are fine. No one needs those German Magura dealios, that's such a hype train on those things.
Man that's why you got a good dude in your corner to MODD that hub motor to a bigger and better gauge wire and hull sensors to see what it do I know EBIKEGUY can do it I would like to see that for you buddy!!
