Hey bro half a year later but just wanted to say I really appreciated your thoughts and liked this video a lot as someone who just ordered all the parts for my enduro build. Great video and discussion, thank you from Canada.
Range Anxiety “RA” 😂 great term. I’ve had range anxiety and didn’t know what to call it. Now I know! RA! 😂 Nice build with monster power and range. Thanks for your all your mod work and information sir. Enjoyed Peace Prospector Tripp
E-bike guy is helping advance progress in performance improvements. Every time i ride i wish i could keep up with traffic. Electric motorcycles are available but they are still very overpriced and most are slow. Hopefully soon anyone will be able to have a affordable and fast ebike or electric motorcycle. For now we need to DIY build. My DIY 35mph ebike is my only transportation.
I'm amazed at the performance your creation has! Seeing what you've done here has given me inspiration to build something like this myself. I wish I'd have watched your videos before my purchase of 2 ebikes. I'd love to DIY my next Ebike. It's the only way to go.
Thanks for the info. There were a number of details that you talked about regarding the dropout and torque arms that you addressed which I wondered about. I have the Snow Bike new in the box when I am ready to start.
Now there's gunna be one Happy Customer! Heck, even my pissy 1500w is bolted to the rear dropouts, I don't trust those jubilee clip torque arms at all, they are crap.
@@E-bikeguy I'm cutting everything down while maintaining the utmost in structural strength. One lean mean surron beating smackdown machine ! You must laugh at guys with their $9,500 surron investments too? Still all stuck at 72v 😅🤣😅 like pfftt.
*NICE VIDEO!* The biggest thing I’d consider would be rim/tire size, or availability of heavy duty tire, my uncle has fat tire I got “normal heavy duty tire” he gets flats very easily (tire are limited at 26” unfortunately) another trick is using 4mm tube and put flat out/slime in tire, next biggest thing is rim true/tire seater on rim correctly so you don’t get crazy vibration at speeds, true your rim before installing tire if need be and and seat tire bead correctly before installing rim/tire on bike it’s so much easier before hand*
Get dual phase in or large cables in ! Larger wires motors are more efficient ! No one believes me 76.75 miles on one pack 86v 8p . When I get the second pack made. It will be 154 miles .
I have a mongoose malus 1500w conversion that has served me well for over a year now but it's a voilamart kit. With the shunt mod I get around 36-38 mph. The battery is 52v 20ah. I want to upgrade to something that will pull hills better than what I have and I think I need to have someone build a battery first that uses a higher bms than 40amp. Would you consider building a battery for me? Afterwards, i'll address the controller and motor upgrade. By the way you inspired me to do this current build even tho it was cheap. Happy trails from Western North Carolina.
Yo, i believe my qs205 may be shot. I am considering the 273. Question, what size are the 12G spokes in the rear, to lace in a 26x4.0 fat rim? the length? thanks!
@@E-bikeguy yours is a 3-speed gearset? I can’t tell in the video of your bike. I was thinking if I can only fit a 3-speed then I would get a ATS Speedrive for the crank pedals.
Yo Tommy ,i got my ebike battery on the Radiator 😅🇬🇧 it makes all the difference in wet and rainy England, i get near twice the range in summer than winter over here so i like to give it a good warming before i set off ,she's only 10ah but i got nice LG cells and bike ,only weighs around 41LBS so i can go 20 miles 🤘🤠🇬🇧 ,I'm saving for a 36v 21Ah with 21700 cells for that MOLI GOODNESS 😅, have a gud'n Tommy and family 🤘🤠🇬🇧❤🇺🇸⚡⚡🚀💣 I'll try keep it under 20mph coppers 🏍 🚓
@@E-bikeguy where can I get in contact with you to help me select my motor, controller, etc? Love to have a discussion to make sure I’m getting the best parts for my conversion.
Hola from Puerto Rico,that’s a great info on the motor I have a v1 QS that I got before COVID-19 but it came damaged from shipping and have to get the new hallsenser for the motor any info on what tipe of controller I can use on it 84 v battery thanks and keep the good work God Bless always.
The motorcycle rim qs205 has the same length axle as the 273 fat rim, I bought same as your original qs205 mountain bike rim it has the shorter axles, I just got the same fat tyre bike as you with the high carbon steel, it's looking like I'm gonna have to bend the dropouts Inwards. You think this is a good idea? I just got done building my friends one with the motorcycle rim and welded and bolted some chunky 5mm steel torqe arms on there, I couldn't believe the speed of it hahaha 63mph and 10kw of power but I could only do 40 on it before shitting it 😂
@@E-bikeguy sweet my man, I'm gonna be bending the dropouts inwards around 15mm each side then filing the dropouts straight so my mtb rim qs205 will fit! Steel frames are great for customizations! I'm gonna get similar forks to the ones you had on your qs205 build 👌 stay safe 🎉
I installed a marine on off switch like you had on your bike. Prevents accidental throttles! I turn it off when getting on it off the bike. Also prevents the connection spark!
I have an issue with my 72v 3000w ebike I have nbpower kit my throttle gave out which i thought but not sure. so i order a new one with a new controller just in case it got here I put it together. it seemed to work for a day today on my way back from Walmart it did it again throttle gave out do u have any idea what i can do to locate the problem
I found the problem after numerous tests found out it was my battery the BMS was shorting out luckily it was under warranty and I got a new one so you were right there was a bad connection
The electric bike I want to buy will have a motorcycle seat and with 21inch wheels from the saddle down it will be 95cm high while with 19inch wheels it will be 92cm. I am 1.75cm tall, are you saying that 21 is too tall for me and that I will be uncomfortable driving when I have to stop?
@@E-bikeguy One last question, an 8kw and a 15kw consume the same battery going at the same speed or does the 15 consume more? Honestly, I prefer to have more range than speed, since the maximum I would push it to is 100/110 km/h
Hey ebike guy can u pls do a video on how you cut,prepared and welded the top tube on as i love building bikes and my ebike conversion is on a merida bug nine frame and triangles tiny
How much does that beast of a battery weigh? My 72v 40ah comes in at just under 50 lbs! Makes the bike feel like a motorcycle. The range is incredible. I went 24 miles and the charge indicator says 99% battery left. I'm guessing a100miles easy.
Well this particular bike has a frame large enough to fit the battery. I looked at a lot a fat tire bikes and this one will be the best bang for the buck.
Thank you, hey it looks ugly to some I seen worse, but i built 3 so far so obviously its Appling to most people and that one thing we have a choice you don't like you dont build or buy it. do you have a mountain bike frame that will fit this battery?
@@E-bikeguy for that huge battery, no I don't. maybe a custom battery bag may clean it up a lot. cheat code: can be done for cheap by a marine upholstery shop. plenty in FL.
The 273 is a class of motors 273mm in diameter. QS and some others make the 273 in 40H (4kw) 45H (6kw) and 50H (8kw), specifically designed for bicycles, not motorcycles. The way you can tell is the bicycle motors have 6 tiny holes drilled for tiny little bicycle brake rotors, and also have threads on the other side for freewheel. As the magnets get wider, the stator gets wider, the motor gets wider and the dropout size gets wider. The other clue this is specific for bicycles is its spoke holes are for bicycles spokes, not motorcycle spokes. The 273 is also made for scooters/small motorcycles with either spokes (real motorcycle spokes) or cast wheel. These also typically have 3-4 bigger bolt holes for scooter/small motorcycle disc brake rotors. These rotors are thicker than bicycle rotors. The Stealth Bomber style ebike is a crossover, some use the bicycle components, such as the bicycle hub motor shown here, some prefer to use the scooter/little motorcycle motor with thick spokes and beefier brake rotor. The QS 273 is also available in 70H (12kw) for small motorcycles. It is available in 6.0”x17” cast wheel. If Ebike guy buys this motor and puts it on his bicycle, your comment would be correct. It won’t stop him from doing it, but it would be correct. Lol
I noted all of that. I can't wait until you install the steering damper. I really want to see the top speed. And I'm already preparing for that bike. 😅😊🫡
Good discussion, it was you who inspired me to build mine, and I been happy ever since,
Man I'm so happy bro 💯 glad I had a impact on ya!!
I rather have a tommy bike than a motorcycle tbh so I built 1 as well 7 months ago. Now I'm working on a 2nd tommy bike using 84v 😅
Good to know the axle is longer on the 273 !! Great info for people considering a QS build!
Thank you, I definitely wanted to let the people know

150mm? Why so small? What kind of frame are you starting with? Most of the fat tire bikes I see are 190 something 175mm.
The axle length is long to accommodate the dropouts

Well this particular bike has a frame large enough to fit the battery. I looked at a lot a fat tire bikes and this one will be the best bang for the buck.
If your bike is that fast why don't you put it in the Guinness Book of World Record. And do you have a Instagram
Will a bac8000 controller be overkill for this motor. I have a stealth bomber frame
Oh no, not at all. Check out @ChrisCrossing Wires on UA-cam. He has a stealth bomber with that setup, bac8000 he doing some impressive speeds.
Ive got the original axum buikd, but if i ever upgrade it will ne to this. I like the idea of kf 4" on the road ve 2.6

Just wish it didn' look so much like a death trap. It's fast but ugly af. think it's time for a new frame now that you have the build on lock.
