The idea of this video is good, and the watt vs speed give a good approximation of top speed. However, the info is not correct. A 1500Watt motor is/should be rated for 1500 w continuously, but it will easily provide 5000 watts wheel power if you feed it 8000 watts of battery power. Also, a ‘5000 watt’ hub motor can be more efficient at lower speeds (say 35 mph) than a 1500 watt hub motor. The motor size mainly determines the maximum heat (watts) it can shed and the maximum amount of copper fill that will fit in the motor. So a big motor can be just as efficient and slow as a slow motor, if you feed it less power. It is heavier though, so indeed you should consider the power and amps and top speed that you want, and choose motor, turn count, battery, bms and controller accordingly. Everything should be in balance, although it is always nice to have some spare capacity in your battery, bms and controller. Then you could always increase the power if you want to…
Great vid. Answered the exact questions I had, but with the 12 volt light and bluetooth lock was something I never considered or even knew about. I want to build it right the first time.
I built a 72 V e bike with Crystalite hub drive speed motor on a KHS mountain bike. I bought the hub, battery and controller as a kit from HPC. The battery goes in a bag with the controller bolted on to it. It has no peddle assist, only throttle. The disk brakes it came with were inadaquate for a heavy bike like this, so I put on Shimano hydraulic brakes. This was a good idea because the stock brakes were really weak. I also replaced the front derailleur with a single chain ring since I only peddle at slow speeds and rely on the throttle most of the time. The top speed is over 40 mph. I think I got it up to 45 mph once, but I usually ride at 20-25 mph.
Yes, you have power the way that you have your bike set up is where I’m trying to get it except I have to use a different system because we have different electric bikes. You did a very good job with yours very good. It’s gonna last a long time a lot of people they ruined their electric bike by just worrying about speedsoon as they get it and then they’re burning out the motor they’re burning out everything not knowing the first step should be range and getting to know your bike first unless you’re already professional you know whatever
true words dude! i have 3000w hub motor on enduro ebike frame, and 72v 30 ah pack/ honestly it'S more like 26-28 AH with 50A bms, short burst up to 90, i had an 80A controller limited to 50A but it was already to much for my battery, i can go up to 70-80 KM/h but it's not worth the amount of power it needs to get up over 70 KM/h so iam trying an sabvotonsvmc 45A controller (the same as inyour bike) and that shoud fit well!
Just because you can't afford the 40 to 56 amp hour 72v battery doesn't mean the 8000w and up Ebike kit or components are overkill. It's honestly what everyone wants subconsciously. That's why I'll have one in 2 months.
Why did you jump to "just because you can't afford"? Given most people here probably drive cars 10x more expensive, you're talking nonsense and just come off as a real D. Little man, you're buying an Ebike. You're not big, or impressive at all. Get your ego in check.
Exactly you have to ride the e-bike differently which includes talking trail and paths. Doing 50mph all the time in a long stretch of road is not recommended because it eats through battery like juice. I take the road only when I need to. If there’s a bike lane then it’s a good excuse to slow down a bit. If there’s a path or trail I’ll definitely take that as well. All of that is for nothing than preserve as much battery as possible. Unless you can afford a 72v with like 200+ ah battery. Then you can throttle all day log
I have the 3000w kit and it gets roughly the same speed at the same watts as yours, so you don’t really lose much power at all. The hub is a little heavier but it’s a negligible difference.
My 500w hub motor with 48v 13ah battery would do 30mph max and would range @ 20 miles on throttle easily (i never actually ran the battery out). My 750w mid drive 48v battery will do 34mph and i weigh 236lbs and the bike has a 27.5in wheel . Everthing you say is true and you provide some great information.
30mph (I'm presuming on a level) with a 500w motor running 48v is impressive, What controller you sporting on that puppy? The motor windings must be decent.
I wouldn't fret too much on your first build not being ideal. I went through 2 iterations to get a bike I like. Although I started with a folding bike ebike I got for 400 bucks, then decided to build my own. I ended up using Grin Technologies GMAC 8T with Phaserunner controller and paired that with a 72v system. Your speed estimates are kind of misleading, your max reachable speed can be extended by using flux field weakening while sacrificing range.
100% correct I just got my electric bike as well and I love it and yes speed I got mines. It only goes 15. I’m already waiting for some items to come in to upgrade the speed. I’ll be going after that will be 40 miles an hour and that’ll just be my top that’s my just in case that’s my speed just in case I need it. I have it that’s gonna be my third mod2nd mod will be 22 and third mod will be 12 and I leave it on too if I’m just cruising around and I could still go above that if I hit the throttle like you said it’s about being safe one of those guys that used to have electric bikes just across the street I thought I was gonna get hit by an electric bike before I get hit by a car that’s how fast they can go and even in a bike line isn’t all safe. You always have to have a finger on the break the back break
I get 28mph out of a 500w hub 48v battery. I ride it to work 6 miles wide open and the hub hardly warm when I get to work. I'm about to drop 60v in and see what it do. Worst case I blow the hub and have to go bigger 😂
so my old ebike and my current gasbike i will go top speed all the time but I had a 36v 500w ebike and now have a 39cc 4 stroke so the top speed wasnt faster then traffic ever. my new bike is gonna be 48v and 1500w so maybe i might not go full speed,we shall see in a couple days.
very! a 48v 1000w motor system will only get you to about 20/25mph with a range of about 20/25 miles. a 48v 1500w system will get you to about 35/40mph with a range of about 30/35. slight increase in both range and speed but I'd say it's definitely worth the extra little bit you spend on getting higher speeds and longer range! (this is all dependent on the weight of the rider and bike itself I should mention as well)
The difference is mainly torque and a bit of heat. Motors with higher voltage can deliver more torque, which feels more powerful especially when accelerating. A 48V motor can spin faster but as soon as you sit on it its slower. Also since 2000W with 48V means more amperage than with 72V, the wires get considerably warmer, which limits the time you can go full power before overheating
The people who get any motor under 1,000 are maybe not knowledgeable about what they’re getting at first, eager just to have a Ebike, eager but have buyers regret cause now they should’ve waited to get more money for a better motor, or just don’t make enough money and that’s all they can afford. I’m more for the 5k and up but of course I don’t need to go real fast but it’s nice to have that extra power when needed. I typically like to try to research and educate myself on what I can do I only need to maybe buy things once and if anything upgrades then all I need to do is buy that part to add on or replace it. Not knowing what your buying is what gets people cause they don’t realize this. Just like buying a car, appliances, etc. people just use it and don’t know how to maintain or the best money for their buck. It’s a tiring process considering every company thinks they are #1 and even if they know they aren’t they have to sell themselves to the masses to convince us they are which is the marketing hype. But the sad truth at times is when a new company actually gets popular sometimes that they still buying inexpensive stuff that breaks down but the product looks good on the outside.
Is there anyway for me to build my beach cruiser (single gear) into the same set-up as your's? I've really been looking into building mine that way. Do you have any preferences on the website to use in order to get the kit for it?
I just built a Trek beach cruiser with a motor bicycle engine kit. It cruises at 30Mph I recommend getting one with disk brakes or good v brakes at a minimum. My neighbor has a 750 watt 52v kit and it keeps up but I can go farther in a tank of fuel, not that that has ever been an issue.
I built mine mate, It is stupid fast and dangerous but so much fun it was worth the build. 72v 80 amp controller and 3000w watt rear hub motor on a 26 inch rim using a 26 x 2.25 tyre
Has the battery got a BMS? Should be ok with 1000w hub motor. I have 2000w with a 48v 25mah battery with 40a BMS & KT-LCD3 display & KT controller. Battery only allows me to get around 31mph as it's max is around 1200-1400w max output. 😏👍🏻
Been looking into e-bikes for years would love to do this instead of buying one for much more. Do you have to buy the battery separate? If so will any battery work with it?
Check out HI Powered Cycles novelty electric bike called the Typhoon Pro. 26x4 rear tire 27.5 in front. It uses a Hub drive but placed in the bottom bracket as it is a mid drive bike. I think it is the very best you can buy.
Rider weight and bicycle wheel size are a big factor in ebikes under 5000w. If you had a 2000w(3200w peak) motor and a 20 inch wheel bike with a 300 lbs rider max speed would be about 32 mph. If you had 29 inch wheel bike and a 150 lbs rider max speed would be 48-50 mph. So with me (300 lbs) and 40 lbs battery on a 29 inch bike I am guessing it will top out at about 41-43 mph. I'm guessing all your measurements are for standard 26 inch mountain bike.
im 150 trying for 28 inch wheels and i might copy most of this set up with the same 2000@ motor 28 inch wheels instead and ill try to find a nice light bike hopefully not a mountain bike would perfer decent road bike with sturdy frame the battery im looking at is basically same = about 1 more amphour about 18 pound battery im hoping to peak about 44. with your math i could maybe see 50.. but i would probably never hit that as thats super illegal in the states decked with some road ready equipment maybe i can get it registered, or just have a stealth cycle sleeper kinda build and keep it at the 25-32 mph limit as hes saying to avoid any law breaking and have a nice solid range!... what do you guys think? and is a road bike style even viable i see that these wheels are about 2.5 inches idk if i will be able to find a light frame or that styled frame that could fit those tires size but all the information helps.
oh and the DIY set up seems to be pretty much plug and play just need the right size bike for it as i am basically gonna copy this video pretty much exactly finally would like to add is this battery waterproof florida has rain alllll the time... and lastly all in all the price range in which im looking at is about 13-1400$ usd just follow this video and make whatever slight tweak and you will land in the right spot.
I hope you read this you mistaken 1500 W will give you 42 mph in Eagle unlock it you can go easy 46 mph. If you put the right battery you can go 50 mph the only thing they don’t tell you That the wires will start to melt a 2000 W motor will give you more than 50 mph without being on lock when you unlock it, you will get more than 55 mph
I put the same motor on a 2019 RadCity. With the stock 48v battery it tops out at 28mph. Throttle only I get about 14 miles of range. Just bought a 72v 20ah battery,supposed to be here in 2 weeks. Hope I get more range.
did you get the (unit pack power official) U004 72v 2000/2500w 19.2Ah battery? if so is it any good? if not do yk the base of the battery you got? I have the same 72v 2000w rear hub drive motor and I'm looking for better speed and longer range.
@@_daldoly_ Yeah. The UPP battery is great so far. On pedal assisted 3 I get about 50 miles of range. Top speed is just like NPL said in the video. Mine tops out at 42 mph.The only problem is the battery will fully charge to 84.3 volts and my controller cannot recognize the voltage until it drops to 83.5 volts.
@@stealthxg5045 Ok so the death and or paralysis won't be any worse than the death and or paralysis from a 40mph motorcycle crash which makes it okay???????
@@nhennessy6434 Don't understand what point you're trying to make. Crashing at 40mph is crashing at 40mph. Doesn't matter what kind of bike you're riding.
I was hit from behind on my e-bike by a car that swerved into me. I was going down hill at about 20-22 mph with no traffic ahead. My injury was a broken hip.
I liked everything in this video and I wanted to ask you about the motor I am thinking of, which is 3000 watts and a 72 volt 80 amp controller. What is the appropriate battery for this motor?
In fact, 750 watts is not a _technical_ legal limit -- it's the e-bike legal limit, end of story. I have no issue with people building more powerful e-bikes as long as they realize they're eventually going to get caught riding them over the speed limit on a bike path or greenway. You don't seem to ever pedal that thing, so calling it an e-bike is a bit of a stretch.
My ebike is 1000w and goes about 30-35mph. A cop once asked me how fast it goes and I said 30mph on a good day and he left. Cops really don't care as long as you're not doing anything crazy, at least in the US.
as a motercycle enthusiast and an individual who has there motorcycle license i agree! 1000% getting it road ready and possibly registered and tagged is ideal! but getting a vin number for a bycicle might prove difficult ultimately i want a device that will assist at stable 20-25 mph at high ranges of 60+ at a price range that is around the same as typical ebikes in that class but the ability to scootmagoot! incase of whatver situation im in, as i care little about off road but its a + and also care little about keeping up with cars as fitting a bike that has options at 1/4th the price point of a decent scooter motorcycle or gas guzzler in general.... besides anyone can craigslist a honda less than 1500 and ride it till the wheels fall off but kinda defeats the point when 2 wheels and electric seems more effecient in my town as my entire town is a 18 mile radius!! tops!
I think he failed to mention here was what the limitations of the BMC inside the battery pack. They typically have maximum amperage cut off's that can limit the power available from the battery back to the controller but then feeds the motor you have to have a good match on that
ebike boy is at it with the most straight forward explanation on this topic that I came across so far on youtube.

a 3000w motor does NOT draw more amperage than a 2000w motor, It depends on the load put on the motor not the wattage of the motor.
When I first got into e-bikes I have been obsessed with range.
I get 28mph out of a 500w hub 48v battery. I ride it to work 6 miles wide open and the hub hardly warm when I get to work.
I'm about to drop 60v in and see what it do. Worst case I blow the hub and have to go bigger 😂
The first question I always get is “does it charge while you’re riding it?” Like no. This is not a perpetual motion machine
A 750w geared hub at 72v at 30A will go about the same speed and extend your range drastically, also you'll get 90nm of torque...
Thanks for the info bro
alot of stuff is missed in this video ; you didnt talk about tyre pressures and how that can save battery aswell as safety .
so my old ebike and my current gasbike i will go top speed all the time but I had a 36v 500w ebike and now have a 39cc 4 stroke so the top speed wasnt faster then traffic ever. my new bike is gonna be 48v and 1500w so maybe i might not go full speed,we shall see in a couple days.
I been go through 6 hub motor kits blowing up and ride for awhile and now I fouse on my diy sleath bomber ebike same high speed as $4,000$ ebike
This is the way
I just bought one of these kits and was worried how it would do at going up or down a curb
Any thoughts on 1500w motor with 48v system?
Is it really different from 1000w motor?
very! a 48v 1000w motor system will only get you to about 20/25mph with a range of about 20/25 miles. a 48v 1500w system will get you to about 35/40mph with a range of about 30/35. slight increase in both range and speed but I'd say it's definitely worth the extra little bit you spend on getting higher speeds and longer range!

I hope you read this you mistaken 1500 W will give you 42 mph in Eagle unlock it you can go easy 46 mph. If you put the right battery you can go 50 mph the only thing they don’t tell you That the wires will start to melt a 2000 W motor will give you more than 50 mph without being on lock when you unlock it, you will get more than 55 mph
what motor are you using? what kit
My system is a 2,000 watt 72 volt 20ah setup with a 45amp controller on a mongoose ledge x1 mountain bike.
I put the same motor on a 2019 RadCity. With the stock 48v battery it tops out at 28mph. Throttle only I get about 14 miles of range. Just bought a 72v 20ah battery,supposed to be here in 2 weeks. Hope I get more range.
did you get the (unit pack power official) U004 72v 2000/2500w 19.2Ah battery? if so is it any good? if not do yk the base of the battery you got? I have the same 72v 2000w rear hub drive motor and I'm looking for better speed and longer range.
@@_daldoly_ Yeah. The UPP battery is great so far. On pedal assisted 3 I get about 50 miles of range. Top speed is just like NPL said in the video. Mine tops out at 42 mph.The only problem is the battery will fully charge to 84.3 volts and my controller cannot recognize the voltage until it drops to 83.5 volts.
If you wipe out going 40mph on an Ebike what happens? I'm guessing either death or paralysis.
How would it be any different from wiping out on a motorcycle other than the weight of the bike crushing you for a motorcycle?
@@stealthxg5045 Ok so the death and or paralysis won't be any worse than the death and or paralysis from a 40mph motorcycle crash which makes it okay???????
@@nhennessy6434 Don't understand what point you're trying to make. Crashing at 40mph is crashing at 40mph. Doesn't matter what kind of bike you're riding.
I was hit from behind on my e-bike by a car that swerved into me. I was going down hill at about 20-22 mph with no traffic ahead. My injury was a broken hip.
My man you must be crazy to ride an ebike on rt 22
I liked everything in this video and I wanted to ask you about the motor I am thinking of, which is 3000 watts and a 72 volt 80 amp controller. What is the appropriate battery for this motor?
How much does your ebike weight?
about 75 pounds
At this point pedals are useless and idk if pedaling (easy 150watt) makes difference on battery life.
speed? power? hey it's a bike.
My 72v 3000w Kona Tropica does 55 to 60 mph
In fact, 750 watts is not a _technical_ legal limit -- it's the e-bike legal limit, end of story. I have no issue with people building more powerful e-bikes as long as they realize they're eventually going to get caught riding them over the speed limit on a bike path or greenway. You don't seem to ever pedal that thing, so calling it an e-bike is a bit of a stretch.
My ebike is 1000w and goes about 30-35mph. A cop once asked me how fast it goes and I said 30mph on a good day and he left. Cops really don't care as long as you're not doing anything crazy, at least in the US.
as a motercycle enthusiast and an individual who has there motorcycle license i agree! 1000% getting it road ready and possibly registered and tagged is ideal! but getting a vin number for a bycicle might prove difficult ultimately i want a device that will assist at stable 20-25 mph at high ranges of 60+ at a price range that is around the same as typical ebikes in that class but the ability to scootmagoot! incase of whatver situation im in, as i care little about off road but its a + and also care little about keeping up with cars as fitting a bike that has options at 1/4th the price point of a decent scooter motorcycle or gas guzzler in general.... besides anyone can craigslist a honda less than 1500 and ride it till the wheels fall off but kinda defeats the point when 2 wheels and electric seems more effecient in my town as my entire town is a 18 mile radius!! tops!
I love bacon
I think he failed to mention here was what the limitations of the BMC inside the battery pack. They typically have maximum amperage cut off's that can limit the power available from the battery back to the controller but then feeds the motor you have to have a good match on that
I was looking at this very battery. What is a better option for a BMS?
@@marthamryglod291 Keep the BMS inside the battery. It's better. Ssfer, lasts longer, runs cooler.
I want this kit and i am 50kilos 😏
LOL thats like 52mph... and easily 60 miles at 20 miles an hour only throttle roughly... nice bro nice!
That's horrible range for 72v
The most important thing for me is the range I want to be able to stay out there longer. Go further plan my trips just go out for fun.
