Direct Drive VS Geared Motor electric bike
EBikes have a few different motor configurations. Here we’ll discuss the difference between the direct drive motor and the geared motor.
Direct Drive VS Geared Motor electric bike
CategoriesApparel
This video doesn’t mention anything about braking. Geared motors cannot regen brake while direct drive can which makes a huge benefit on overall bike maintenance. Depending on how strong you set your regen (I set my motor to max) you almost never have to use your physical brake. I only run a front disc brake for emergency stops and don’t even both with a rear which helps offset some of the weight penalty
40 Mn direct hub VS 80 geared ?
So I still don’t understand how geared hubs are better than direct drive .
In terms of efficiency that removes the mechanical loads from the gears but I could somewhat agree about the torque part.
great super informative yet short video. 10 thumbs up! thanksA
Thanks for the review, very helpful
Great review…. NO website link in the description???
I ride my bike unpowered and without battery…..my DD motor bike is a pig to ride without battery unless I power it a bit.
My geared hub bike is much easier to ride unpowered.
If there was a freewheeling motor version of a DD design I’d buy it in a second!
Great video. Forums have a wealth of information, but much of it is outdated. In the last 7 years, the ebike scene has changed drastically. Forums are great for getting the history of ebike, but reading recent periodicals will give you relevant and recent info. The people on forums talk about DIY motors. These days, you have so many more options. LunaCycle, Hobby King, LeafBike and even Ebay have been huge game changers in the last 3 years (Ping Battery, Em3Ev/Cell Man, other small vendors are falling behind). In the early days (pre 2015) an ebike once cost over $750 + a lot of DIY. Nowadays, you can get better kits for under $500 with minimal DIY.

FYI unless this has already been addressed A gearmotor has a one way clutch so you are not spinning the coils or magnets to regen. Also since there is a 6 to 1 gear ratio the sudden transition from drive to coast creates a massive load on the nylon planetary gears and will shear the teeth
Yup that’s why direct drive motors are increasingly more popular when it comes electric skateboards.
Hii
Thanks for advices and video
I want to know about life span of the geared motors????????
I heard the gears and clutch are not durable and to me will be impossible almost to find a new clutch .
I actually like geared but want to be durable. I want to use for commuting.
thanks ! Greetings from Germany.
How hard is it to replace the wires on a geared motor that are damaged at the rear axel?
id like to see any of those motor vs MY1020 500w 36v (alike)
i didn’t see any of those motor in your video(or any other video) that compare them
since you can change the gear 2-3 test is needed 1 made for speed 1 made for climbing and 1 between both
what’s the max speed of 350w geared motor as well as 500w geared motor?
Excellent! Thank you!
FYI "george kontopoulos" the speed junkie you show at 2:00 is NOT using direct drive hub motor, but a planetary geared mid motor (8000w) that uses the bikes own transmission.
Haha I like the Third Strike music 😉
Hi. I have a 350w 36v rich bit rear geared motor. It requires a gear oil change. Please can you tell me what oil i should use? Many thanks
great video, and it answers half my question. I am trying to track down exactly what kind of power requirements I would need for a geared hub motor. I am a big dude (250lb) that lives on a very steep long hill. I’ve seen for my girth a recommendation of 48v 1000w direct drive, but I cannot seem to find a geared drive more than 36v 500w. Any ideas what i should be shopping for? is geared 36v enough? do you perhaps have a video that covers this info?
"Geared motor will chew through your battery" – "Geared motor is the way to go" ??????
Finally an explanation. Thanks!
As always, succinct and filler free! Thank you.
I have a question, I thing you can give me answer.
My ebike is 500w motor,
use 48v 17ah.battery,I need to upgrade anything’s to use
48v 28ah battery ?
Thanks
Hi Mike, nice video, thanks! It’s a pity though you didn’t mention one of main factors to help choosing one’s best solution.
Direct Drive motors have the so colled ‘cogging’, if you want to actively pedal (and may be even use your e-bike without electric assistance for a while) you hardly can.
Geared motor have no pedalling resistance when electric assistance is not present.
So is a geared motor the same thing as a speed motor? I’m trying to figure out the difference between a direct drive and a 7 speed motor. I was going to buy an electric bike, but one of the options I have to decide on is what type of drive I want. The direct drive comes standard I guess (in other words "$0.00" is listed next to it on the list) and the 7-speed option would add $149 to the price of the bike. I’m am new to e-bikes, and having watched about 60 or so videos about them in the last few weeks I still don’t understand, among other things, the difference between a direct drive or a 7 speed. Honestly, I barely ever heard the term "direct drive" in any review videos I’ve seen. They all have always mention speed motors (usually 7 speed, but a couple mentioned I think 9 speed, and one of them mentioned a belt drive, whatever that is).
If you are a critical listener as are many folks who HATE on ebikes then there is a big difference in the noise from a geared hub motor versus a "direct drive".
Two Motors, a very small in Front, just for accelerating from zero to 5km/h that switches of when in no load operation after the gearless took over
Geared motors are efficient, small and powerful, but they overheat easily and they break down after a year or two.
3 wheel: tadpole vs tricycle pls . 1 wheel in front or 1 in back
Great info!
geared motors does not mean that are "climbing motor", go back to school and learn a little bit more and improve your stupid grammatical language.
you said geared is to go for. if it chews up the battery i rater go direct drive.
Combine the two features in the same hub, one reduced and one direct from the motor drum via a direct engagement maybe a centrifugal device or similar. From the drum to the hub directly once you have certain speed.
hey hru i have 2 question i just got a electric motor model number MY1016 24vdc 2500 rpm 14.0A 250W and im trying to make a ebike could u help me out and let me know what type of speed control i need and what type throttle i need and could i use to motorcycle batteries to power that motor thanks keep up the good videos
Basic info. Real world tests would make a great video.
Gears have a whine, especially under load, don’t understand why he says he doesn’t hear a difference in the noise.
And direct drive is difficult to find even in China
Hello blue monkey bicycles, I’ve wanted a extremely fast accelerating hub motor bicycle for a while but I don’t know witch motor I should choose can you guys help me?
The speed don’t have to be extreme like 60mph just around 30mph
You didn’t mention geared motors have about 0 resistance when coasting while speed motors have about 10% drag at coast. I like geared motors but I prefer the speed of a speed motor and one can go much farther with minimal stops and peddel starts.
Great video!
Have you ever tried the BionX D-Series motors? They are direct drive and should still overcome most of the disadvantages.
This totally ignores motors mounted on the bottom brack which drive the crank shaft rather than the rear wheel. That’s the comparison I’d like to see made.
Any difference in price? Thanks
Hi mike …can i know how much time does a 48v 10am battery lasts on a Two 250w motors
Mike, you make no mention of how a geared motor is on hills. I have some serious hills to climb around here, including a 1500 ft. elevation dirt road. Your recommendations?
This video is confusing because you keep referring to the two different motors with multiple names for each.
Plastic gears don’t seem dependable, and what happens if you are using a planetary geared motor on the front wheel and the gears break? …does the wheel lock up and I am thrown over the handlebars and die? I think Ebikes need a HUGE amount of work to be a dependable and safe vehicle. I could design one that would be, but no one is interested in making a great Ebike for a reasonable price, the Ebike manufacturers are only interested in the quick buck. Unless you spend $6000.00 on an Ebike you will not get a bike designed for a real cyclist.
For example, I just purchased a motor kit (30 mph) + battery (700 whr) for $400 total. I also got a Nashbar bike for $200. My $600 ebike will weigh 35 lbs, get 50+ mile range. Easily outperform bikes that once cost over $2000.
What do you think about two wheel drive bicycle where the gear motor is in the back and the gearless motor is in the the front, so use the rear wheel drive gear motor to assist accelerate and then use a gearless motor front wheel drive to maintain speed… So both wheels will not be active at the same time
