Hey, what's up?
This is Mikey at Blue Monkey Bicycles and in this video we're going to take a look at
the Brose S mid-drive motor!
If you have a Brose mid-drive motor, or any other mid-drive motor; don't take it off the
bike and try to fiddle with it.
All the electrical and mechanical warranty work should be done by a competent professional
such as the place you got the bike from in the first place.
So don't go voiding the warranty and risking injury or damaging the bike by pulling it
off.
Oh and by the way, this just happens to be a regular Brose motor, it's not a Brose S.
I don't have one in hand that I can actually show you quite yet.
But, none the less, it's a good illustration.
So, let's jump in!
Brose is an electric motor manufacturer based out of Germany that has been making electric
motors for quite awhile, but it wasn't until recently that they came into the US with the
Brose mid-drive system for electric bikes.
Now, Brose doesn't really have a house-hold name the way that Yamaha, Bosch or Shimano.
However, they still compete head-to-head because their mid-drive system has a super, secret
power: It's a belt drive!
I first caught wind of the Brose system just before the American debut a couple years ago.
Back then I got sneak peek at the Easy Motion ATOM bikes featuring the regular Brose motor
(not the Brose S, and we'll get into that in a second).
On account of the motor, it was super smooth and super quiet, and it provided plenty of
torque.
I was very excited.
We tried it out on the trails here in Utah, and it was quite a hoot!
Among its competitors the Brose system is easy the smoothest, and quietest.
Most quiet?
Quietest?
*GOOD ONE!* The internal belt is the key to its performance.
The belt mitigates the noise and friction of a metal to metal gear (or a metal to composite
gear), and it puts a lot of class into the entire experience.
The Brose S sports some really good specs!
The Brose S is still a 250w nominal rating, but it assists up to 380% and supports up
to 120rpms.
And, it rocks 90nm of torque.
The Brose S looks amazing on paper!
Mechanically the motor has a spindel length of 150mm and the whole things weighs in at
3.4kg.
It has physical dimensions of 8.4" long, 5" tall, and 4.6" wide without the spindel on
that one.
Other extra features include a dual free wheel on the motor and a double water sealed internal
system that offers a little more peace of mind.
One bike that really shines is the Pedego Conveyor.
It's a belt drive!
Get it?
Conveyor...
Belt... drive..?
Anyways, it rocks the Brose S system which of course has the internal belt-drive, but
it also as a bicycle has a belt drive for the mechanical gearing as well.
Smoother than Steve McQueen sliding down a baby beluga's buttery back!
You can get the Pedego Conveyor from bluemonkeybicycles.com and enjoy other exclusive Blue Monkey benefits
such as an assembly video, how to use the display and a whole lot more.
Anyways, let's get back to the motor.
Now where other motor manufacturers have an entire system with it; Brose doesn't seem
to mind all that much.
There's a lot of bicycle companies that are using just the Brose motor and then using
their own display or their own battery to make a complete electric bike system.
Even the same bike company using the same Brose motor may have different displays or
batteries.
As a matter of fact, some of the bicycle rocking the Brose system have smart phone integration,
but I'm pretty sure that's a thing that came from the bicycle company.
It's kind of hard to tell the lines start getting blurry at some point.
In an upcoming video I'm going to be comparing the specifications of the Brose S motor along
side of it's newer competitors the Yamaha PW-X, and the Shimano e8000 along with the
Bosch CX motor (I don't have on in hand).
Yeah, stay tuned for that upcoming video.
After that I'm actually going to put rubber to road and try out bicycles that have these
systems equipped, and I'll be able to give you some first hand experience.
Other than that!
Let me know what else you'd like to see on the channel and
I will see you guys on the later!
