6 Reasons Your E-bike Motor Should be 500W or Less | EBIKEBC
Un étudiant de Victoria condamné à une amende pour avoir roulé sans assurance vélo électrique Vous lisez Moins c'est plus : 6 raisons pour lesquelles votre moteur de vélo électrique devrait être de 500 W ou moins 4 minutes Suivant Les avantages et les inconvénients d'un Fat Bike électrique

Presque tous les kits de conversion de vélos électriques et de vélos électriques vendus au détail sont répertoriés à un niveau de puissance spécifique, tel qu'un "vélo électrique de 500 watts" ou un "kit de conversion de vélos électriques de 250 watts", mais cette puissance est souvent trompeuse. Vous vous demandez peut-être : de quelle taille de moteur ai-je besoin pour un vélo électrique ? !

Lorsqu'il s'agit de choisir un moteur pour votre vélo électrique, plus gros n'est pas toujours mieux. Les moteurs traditionnels vont de 250 W à 500 W, mais à mesure que l'industrie du vélo électrique se développe, la puissance du moteur augmente également. Des moteurs haute puissance sont disponibles allant de 1000W à 6000W, mais la question est : moins pourrait-il en fait être plus ? Y a-t-il des avantages à cette mise à niveau de puissance ? Et enfin, de quelle puissance avez-vous réellement besoin ?

Lors du choix d'un moteur, il y a deux facteurs importants. Votre poids et le terrain sur lequel vous roulerez. Un moteur de 250 W est suffisant pour les trajets quotidiens, tandis que la mise à niveau vers un 350 W ou 500 W est bénéfique pour ceux qui feront beaucoup de trajets en montée. Pour mettre les choses en perspective, les moteurs de 6000 W conviennent aux courses de motos et ne sont pas conçus pour être confinés aux routes de la ville.

De manière générale, pour la personne moyenne, un vélo électrique conçu de manière efficace fournit une puissance plus que suffisante à 500 W ou moins. En fait, augmenter les watts de votre vélo électrique présente des inconvénients. Avant de creuser les inconvénients des moteurs haute puissance, il est important de garder à l'esprit que les règlements municipaux standard limitent généralement la puissance du moteur à 500 W. Ces règlements sont entrés en jeu sur la base de principes d'ingénierie et de sécurité.

Pourquoi votre moteur devrait être de 500w ou moins :

  • Dans les provinces canadiennes, la plupart des vélos électriques sont limités à une puissance de 500 W et ne peuvent pas rouler à plus de 32 km/h (20 mph) avec la seule puissance du moteur. Cependant, limiter la puissance des moteurs de vélos électriques ne limite pas nécessairement leur puissance. Même si un moteur est marqué comme 250 watts, n'importe qui peut le connecter à une batterie de 48 V et faire fonctionner 20 ampères à travers le moteur pour atteindre 1 000 watts de puissance.
  • Utiliser un moteur plus gros signifie utiliser une batterie plus grosse pour parcourir la même distance. La batterie étant la partie la plus coûteuse d'un vélo électrique, cela se traduit par des économies supplémentaires.
  • Des problèmes de surchauffe peuvent survenir lorsque le moteur dépasse 1000W. Cela se voit principalement lors de longues montées, ce qui est l'une des raisons pour lesquelles les gens optent pour des moteurs à puissance plus élevée.
  • Les moteurs de moins de 500w ont été largement testés et produits en série. Ces moteurs se sont non seulement avérés efficaces, mais grâce à la recherche, ils sont extrêmement fiables.
  • L'excès de puissance fourni par les moteurs dépassant les 1000W a des conséquences négatives en cas de crash. La gravité et le risque de blessure augmentent linéairement avec la puissance et la vitesse du moteur.
  • Les moteurs 750W, 1000W, 3000W et 6000W sont trop lourds pour le vélo de rue moyen et peuvent causer des problèmes en aval entraînant des réparations inutiles.

Conclusion

La puissance du moteur supérieure à 750 W fournit trop de puissance pour un vélo de rue et devrait probablement être considérée comme un scooter électrique ou un autre type de véhicule motorisé.

Quand il s'agit de choisir le bon moteur, cela dépend finalement des intentions du cycliste. Les moteurs à faible puissance sont peu coûteux, ils sont conformes aux normes légales de la rue, ils sont efficaces et ne présentent pas les inconvénients et les risques des moteurs plus puissants. Notre consensus : plus gros n'est pas toujours meilleur.

My battery size is 16AH which is the factor that determines distance. The 20AH battery would have been better for me to get longer than 35M/charge and the wattage of the motor determines the load and over heat ratio of said motor. Load isn’t just weight, but gradient of the trail. I wish I had known, I’m stuck pushing with a turn meniscus until I can find a good replacement for the motor.

I 100% Agree with Ryan Merrill in everything he said but I would like to add to it, if I wanted a commuter or city bike and lived where there was mostly flat streets and not in San Francisco then a 350w or 500w ebike would be much more efficient then a 750w or 1000w ebike, I know that the government regulations in Canada* are set for 500w and that is just wrong, the facts are that a 750w fat tire 26" wheel with a 4" width (which a lot of seniors or people with disabilities prefer) in rural areas with steeper hills will outperform a 500w, at least the senior or disabled person has a chance of making it without walking their bike up a hill, also that motor is going to work harder in a lower wattage and therefore burn faster, I know the law states 500w but that has to be changed, some fat tire ebikes have upward of 80Nm of torque and that is great but it’s not so great if your pushing that 500w motor up an incline and it starts smoking or gives out. My motto is if I’m wearing a helmet and riding respectfully then who is going to stop me with tech equipment and check to see iff I have a 350w bike or a 1000w bike, Canada needs to change the regulations, if I’m going 20 on a 350w or a 750w then what are they worried about~

Hi, I am 65 yrs old, I want to convert my old Mongoose -TYAX MTB with 26" tire, 8-speed to Ebike for commuting purposes. Should I go for a 500W motor, 48 V with a 24 Amph battery? is it street-legal in NZ? An average speed of 36 km/h is enough. Any other alternative suggestions?

I wanna build one for going to work and its a 10 min ride with car and I want little bit of speed as well
So if I choose the 750 as the middle ground its enough right?

750W potentially gets you to 50km/h of speed, however motor winding / battery voltage configuration should be such that be capable of this speed.

“Using a bigger motor means using a bigger battery to travel the same distance.”

– Correct me if I’m wrong, but this doesn’t seem true. If you were to travel the same distance at the same speed with a 500 and a 1000 watt motor the battery usage would be the same.

What a bunch of BS. First of all, they shouldnt be limiting wattage, they should limit speed. Big Watters bikes have less heat issues, not more. They produce more torque for hills. Big wattage motors are less reliable? Again false. I have 3+ Yeats and 4000kms of riding and still going on my QS 205 v3. I much prefer having big hub and not pushing it that having a small 500w motor and running at its max or past max current in order to climb a steep hill. Big motors require less repairs if your using a hub motor. Last. 6000W is no where near enough for a race bike. Race electric are in the 300KW range.

Everything is about how you program the controller. I have a 32ah battery and can get 65kms ridi g at legal speed with my 24KW setup.

It’s like you wrote the article without experiencing riding on a big motor setup

Can a 1000 watt 30 amp hour battery 48 volt be used on a rear 500 watt evike conversion kit .2025 mph is all I’m looking for simply because I usually put a tow trailer behind my bicycle and I need a little power because I’m an elder man at nearly 67 years old this year and of my license have been taken for various reasons other than drugs and alcohol

Your statement can be true if the 1000W motor runs at the same efficiency as the smaller motor. Normally each motor size has an optimal efficiency working condition based on the rated power. Motors tend to be less efficient when they are too big or too small for the out put power.

Right, they tend to be less efficient. But not half as efficient. You are just handwaving away how asinine your statement is “Using a bigger motor means using a bigger battery to travel the same distance.”
It MIGHT be a few percentage points less at most.
I really hate when supposed experts are caught in a lie, and they dig the hole deeper.

Did some one here claimed “Half as efficient” here? What lie?
for a better understanding see the efficiency chart at this link:
https://i.stack.imgur.com/QuZng.gif
if you get 500W out of a 1000W rated motor, you probably are running it at a considerably lower efficiency, which means lower range for the same battery.
I really LOVE when readers have a passion to challenge and add to their knowledge.

I rode a 500 watt rated ebike
and a 1000 watt ebike
The 1000 watt ebike outperforms the 500 watt
with flying colors.
When you consider motor sizes, charging rate,
distance, peddling, and weight…..whatever……
That’s when all the fun becomes a headache
and you find yourself debating which of what to use.

Using a ebike to and from work i find efficiency to important. The motor rarely runs at 100 % but effiency is often better with high voltage. So you will probably get more out of the same motor running at higher voltage – Take a 250 W 24 V engine – use 48 V battery – and it will be a 500 W motor (lcheck if the engine spec allows for the increased Voltage) When you run the motor cruising – it will be more efficient at 48 V….. When i cruise i am running the motor at between 140 and 200 W.

Same motor, higher Voltage will make it increase the maximum rotational speed. It wouldn’t add to the torque.

500W motor is absolutely enough for 200lbs, range depends on power consumption AND battery capacity; the higher the power the lower the range. A rough estimate for 40 miles, 200lbs, relatively hilly area and 500W motor ebike is that it requires about 800Wh battery. It is considered a high capacity battery in ebike industry. It can be a 48V 17.5Ah battery pack.
If being used mostly flat on 50% pedal assist, you should be good with an average battery too. It all depends on road condition and how you pedal.

FYI I have a bafang 250w motor on, I joke you not, a 45Ah 58.8v battery pack (literally over 200 18650 batteries. It is controlled with a 48v 2000w speed controller with max p out at 40 amps.

The unit flies. Top speed 58 kmh
Uphill I am getting over 45kmh
I only burn out hall sensors if I do something stupid like climb a 40 degree incline.
And I don’t need to charge it every time I get home. It’s range exceeds 150km on a charge.

Every other size motor I put on the wheels is slower. The over fed 36v 250w rear hub wins.

hello Damiano,
I am interested in making a bike just like yours. Can you provide a link or resources where I can find bafang 250 watt motor with 29 inch wheel on, 45Ah 58.8v battery, and 48v 2000w controller please?
question. Your motor and controller are rated for 36v and 48v respectively , can they handle 58.8v?
I look forward to hearing from your soon

I am considering selling my Trek Powerfly 7 eMountian bike and getting a more road oriented bike. I weigh 270 pounds and I am going to ride the new bike on some hills but not on single track and a lot of hills. I’m thinking that 500w might be not enough power and I should go to 750w motor. Maybe the SONDORS Fold XS??

Firstly, you need to check if 750W is considered street legal where you ride.
Secondly, compare maximum torque at ebike wheel, that is what you need to climb the hills, 500W might be enough if you get around 80Nm+ of peak torque.

I am pretty sure your 70 degrees is not accurate. it’s about the vertical.
Our 500W geared hub offer 80Nm of peak torque which reduces about 15% grade of any slope for a 200lbs rider.

I ride 250cc scooter and thinking to move to an electric scooter or bike, mainly for riding on streets. Yes, I will have to put a number plate on it
I guess I will need to reach 40 mph on the streets to stay safe from cars on traffic lights. What power bike should I choose? Also, what else should I consider? Maybe stronger frame, better breaks, motorcycle protective equipment? Thanks

40mph (64Kmph) on a heavier chassis would require 2KW+ power for a reasonable maneuverability. To supply that power you need a big battery pack of 2-3KWh. your ebike should be more than 100lbs and is not going to cost you less than 3K for the battery, motor and other electrical parts.

As one with not an iota of mechanical/electrical sense my concern is bike power relative to charger power.
The grandson has a toy Chinese ebike 150 watts power. The Led reads 15 bars. Each full charge only charges 12 bars no matter how long its charged. Does this mean the charger provides “less” power than called for?

I’m thinking on an E-Bike with 500 watts? Must the charger power provide 500 watts or more?

Charger should match the battery Voltage. there is no such term charger power unless we talk about how quick we want the battery be charged. Not charging more than 12/15 bars could be because of weakened battery cells and have no cure other than replacing battery pack.
When you buy a Li-Ion battery operated product it comes with a standard charger. you can only use that charger.

Not sure if this will help ay of yee, I’m 230lbs, 55, (not fit!), I converted a Dawes Galaxy AL touring bike to an e-bike, 350W, 36V, 12.5Ah. I only ever use it in pedal assist mode, as it means I still get a workout and it only kicks in on the hills, I’ve now covered over 600Kms (lcd trip computer is great), and wouldn’t change it. Never had any issues and unless you really want to be really lazy go for the bigger motors, but personally I don’t think there is any need.

This guy is delusional! Build your bike for the power you want. I’ll never have a 500w or less bike! LAME!!!

Planning to build a DIY e-bike…

I bought a 36V DC, 500w, current rated @ 19A with 2400 RPM.

Can I piggyback (3) 12V 7Aph batteries in parallel and directly connect them to the motor without using a controller? Also, what charger would you recommend for this battery setup? Any pros/cons with just using a switch?

Would you suggest a bigger sprocket on the motor or on the wheel? How fast will the bike go with this configuration? Thx!

Answer to this requires knowing the type of motor, wheel/motor configuration and many more design parameters.

Fat tire 1500w kit on 26″ x 4.0/52v 32ah battery. Should be very fun. 250lbs with 75lbs of towing.

The motor can work on 48V system with some limitation, you have to make sure you are not overloading the motor by applying more power.
If your controller is 36V then you will damage the controller is 48V in used.

SO PLEASE DON’T USE 36v SYSTEM ON 48V.

750W potentially gets you to 50km/h of speed, however motor winding / battery voltage configuration should be such that be capable of this speed.

So if I choose the 750 as the middle ground its enough right?
