How to Know What Power eBike to Get?

What’s the best ebike? How fast can a 1,000 watt ebike go? Here I go over the top speed of different e-bikes compared to their watts.
Battery volts and controller amps play a role in ebike top speed, however hub motor watts is the main source of power.
In this video we compare different power levels to see how fast a 750 watt, 1,000 watt, 2,000 watt, 5,000 watt, and 8,000 watt ebike can go.
750w e-bikes are compliant with most local laws and have a top speed of 28mph making them a class 3 ebike.
1,000 watt e bike such as the 52 volt Ariel rider X class can max out around 35mph.
2,000 watt e-bike like my 72 volt ebike conversion kit have a max speed of 42mph.
3,000 watt hub motors are approaching electric motorcycle speed with a top end of 50mph.
5,000 watt hub motors can reach a speed of 60mph

ebike boy is at it with the most straight forward explanation on this topic that I came across so far on youtube.

[@The205GTIman]

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.

Thanks Bro, Awesome Video! ✌🏾

[@salviaaable]

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!

[@memnoninfinit1214]

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.

[@lawrenceterbell4496]

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.

[@realestatestudent213]

Thanks for watching!

[@solosword593]

Great information brother, thanks. A new sub' ;-)

[@ripp3rjak934]

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

[@shaunhall960]

When I first got into e-bikes I have been obsessed with range.

[@thebestjaiser]

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.

[@rhaize1644]

I just bought one of these kits and was worried how it would do at going up or down a curb

[@303overland4]

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.

[@lukewalker1051]

Agree, the presenter knows his stuff.

[@danimayb]

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.

[@alfredxavier5880]

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 a 72V battery good for a 3000W motor?

[@SunChaserEUC]

Wish I found this video before I built my 1500w bike. It’s fine for now but someday I’ll build a 5kw or 8kw bike

[@fang64]

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.

[@fang64]

I'm guessing you don't like links on your comments, I'll refrain from doing so in the future.

[@JB-dy3mi]

I think of speed as volts, and torque as amps.

[@jackreacher1963]

No no it's how fast does it go. I would people that are not 70 and older there going to want at least 1500 watts. Thanks gor video

[@alirezarostamifard6404]

Any thoughts on 1500w motor with 48v system? Is it really different from 1000w motor?

[@_daldoly_]

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)

[@WesternIronwoks]

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.

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?

[@marthamryglod291]

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.

[@vvvvvv66666]

[@stevenmiller9198]

I don't quite get it what would the difference be between a 72V 2000w ebike kit vs a 48V 2000w ebike kit?

[@doktormerlin]

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

[@garettodd3037]

@@doktormerlin you got that mixed up. Voltage= speed. Amperage= torque.

[@victorvannatter312]

The first question I always get is “does it charge while you’re riding it?” Like no. This is not a perpetual motion machine

[@zarb88]

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.

[@eonreeves4324]

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 😂

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.

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.

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?

[@Jolly-Green-Steve]

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.

[@issacue1528]

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.

In fact, 750 watts is not a _technical_ legal limit -- it's the e-bike legal limit, end of story.

You don't seem to ever pedal that thing, so calling it an e-bike is a bit of a stretch.
