How Does An Electric Bike Work | The Basics Of An E-MTB

– We're all familiar with how a standard mountain bike works, you swing your leg over it, you turn the pedals and
the bike goes along, you pull the brakes, it comes to a stop. However when you add a battery, a motor and a control unit into the mix things are going to get different, you're going to get an E-mountain bike, but how does it all work? Well today we're answering that question and a few other basic questions too. (music jingle) There's two different categories when it comes to E-mountain bikes. One is throttle assist,
the other is pedal assist. With a throttle assist E-mountain bike you simply twist the grip or push a button and the motor's activated, off you go without pedaling. Where as with the pedal
assist mountain bike, you actually need to pedal
to get the motor to engage. If you don't pedal you
aren't going anywhere, and that's the bikes
we're focusing on today. So all electric mountain bikes have three main components that actually make it an E-mountain bike. That being the battery, the
motor and the control unit.

So how does it feel to
ride an E-mountain bike? Well, it's exactly the same as
a traditional mountain bike, you push on the pedals and you go along. It's just got that
assistance from the motor feels like you're getting a
push from someone on the flat, and also when it comes
to those steeper climbs. But how much it assists
you is going to differ too. You can change up via the mode switch. So let's take a look at those
different assistance levels. Your E-mountain bike is going to offer you a few different levels of assistance that you can dial this in via
the power modes on the bike. Now the Shimano E8000
system I'm using today here on my Canyon, has the settings from off, all the way up to boost mode. Now off is going to make it feel like a heavy standard mountain bike.

You can pedal it but it isn't
going to feel very nice. Then you have a ECO, which is going to give you
a little bit of assistance, it actually gives you 120% of assistance. Then you have trail which is
kind of in the middle setting. Then you have boost mode which
actually is 300% assistance, and that's going to give
you a lot of assistance on those bigger, technical climbs. But all those different power modes are going to have a different
effect on your battery.

Speaking of batteries,
they come in all different shapes and sizes when it
comes to E-mountain bikes. Some of them are mounted externally, you have semi-integrated batteries, you have batteries that are
mounted in the down tubes. Now a battery is measured in watt hours. So you have smaller batteries
which are lighter weight, you have those bigger batteries
that hold a lot more charge. In simple terms you're comparing it too an AA battery compared to a D battery. The bigger the battery the more miles you're going to get out of it. So what about charging your battery? Well it's exactly the
same as a mobile phone, you simply plug your charger into a wall, connected to the bike, leave it for a few hours and that will top the charge up to 100%, and you can go out and ride again.

Now some batteries differ in the way they're mounted to the frame, meaning that you can actually take the battery out of the bike, take it to your workshop or your bedroom, or wherever you charge your battery, connect it to your charger in the house, then put it back on the bike. Some bikes however have
an in-built battery, meaning you need to take the whole bike into the house to complete that charge. When it comes to motors
on your E-mountain bike well they're going to come
with a couple of options too.

You can get hub drive units, which means they're going to
be mounted in the back wheel. Now these are a great
introduction to mountain biking, they're great for commuting
and light mountain bike use. However, you want to
go real mountain biking get out in the woods, you need mid-drive unit, these are mounted in
the middle of the bike, they power the cranks rather
than the wheel itself. They're really great for
off-road mountain biking. The display and controls are also going to differ from
brand to brand as well.

You're going to have brands such as Bosch, which has things such as
sat-nav on the heads up display, whereas the Shimano display tends to be a little bit more discreet, but you're going to have
all those vital stats and information on there. Some brands such as
Specialized goes super stealth meaning you're just going
to have a couple of buttons on your handlebars to change
its power assist modes. The display on your E-mountain bike is a wealth of information. On there you're going to find
things such as a battery range, you're going to find out how much range you've got left in the battery. And also what power mode you're in, how much cadence you're doing, how many miles you've done, and your average speed. It's absolutely loaded with information, but they're going to
differ from brand to brand. So how far and how much range can you get from one E-bike battery? Well, some battery manufacturers
have a range calculator, meaning you can go to the website, enter in the details of you and your bike, and it'll predict roughly how much miles you can get out of your E-bike battery.

So that's a really great way. Another great thing about the heads-up display on your E-bike, is it will actually preempt how many miles you've got left in the
tank when you're on a ride. So whichever power mode you're in, it will preempt the ride and let you know how much miles are going to be left, in that selected power mode. But there are many things
that can affect battery life, such as things such as ride away, how much elevation you're doing, the trail condition, the
temperatures, your tire choice. The list is pretty much endless of all those different factors that can affect that range of the battery. Right we've talked all
about the various components that make an E-mountain bike, but how does it all work together to make that bike move forward? Well it's a simple case of
finding the power switch, press that button on, wait for the system to start up, then you swing your leg over the bike, you select which power
modes you want to ride in, be it ECO all the way up to boost.

Place your foot on the pedal, once the pedals have got
a bit of load on them the motor knows that you're
going to need some assistance, then it's a simple case of pedaling like you would do a regular mountain bike, and set off into the woods. Easy as that. But how fast does an E-bike go? Well most E-bikes are
actually restricted to 25 kilometers an hour in most of Europe, or 32 kilometers an hour if
you're in the states or Canada. Now it doesn't mean
that you can't actually go faster than those speeds, it's just the speeds that
the motors will assist to. Meaning if you go over that limit, it's up to you, and how hard you're going, and obviously elevation
going to help out with that. Now the way that the bike knows
that it's going this speed, is by the speed sensor, usually on the swing arm
or on the back of the bike, it usually has a magnet to tell how many revolutions that
wheel is actually doing. That combined with the heads-up display, it's going to know when the
motor is going to assist you and when to drop that
assistance levels off.

So where can you ride an E-mountain bike? Well here in the UK I can
ride a E-mountain bike wherever you can ride a
traditional style mountain bike. But elsewhere in the world the
law is changing all the time so it's up to you to check where you can ride your E-mountain bike. Do you need a license to
ride a E-mountain bike? Well, no you don't need a license to ride a standard, restricted E-mountain bike. But if you are riding
this higher powered E-bike such the as the R-Pedelec
and the S-Pedelec, then you're going to need
a license, tax, insurance and a proper moto style helmet. However those rules differ
all around the world, so it's up to you again
to check those rules out, whether you need a license to ride those higher powered E-bikes. But if you're riding a
restricted mountain bike, then it's not going to be a problem. So there you go, really hope you've
enjoyed today's video on how an E-bike works. Give a thumbs up if you've enjoyed it.
