7 Things You May Not Know About E Mountain Bikes


– Now if you’re a mountain
biker thinking about an e-bike these are few things you might not know and how an e-bike differs
from a mountain bike. (relaxing music) The term e-bike means there
has to be pedal assist. Anything with a throttle is not an e-bike. And anything that assists you over 32 kilometers an
hour is not an e-bike. In most parts of the
world, this bike is legal to ride anywhere a
normal mountain bike is. (relaxing music) So number one, the bikes have sensors. This bike has a sensor,
it’s on the chain stay inside of there, you can see. There’s a magnet mounted
to the spoke and that gives the bike the information
about how fast you’re going. ‘Cause e-bikes will have a
pedal assist cut-off speed. In the UK, that 25 kilometers an hour, in the U.S. that’s 32 kilometers an hour. Above that speed the bike
will stop assisting you, it’s then all up to you. Some bikes also have them
mounted to the rear disc bolts. Basically, somewhere on that
rear wheel will be a sensor to tell you’re bike how far you’re going. So most e-bikes have a
computer up on the bar to give you loads of information. And they do differ dependent on the motor system on that bike. So this bike has got a Yamaha system. I’ve also got that remote
off on the left hand side so I can flip through my power
modes very easily on the go. I’ve got an LED on the
top of the screen there that changes color depending
on the power level I’m in. Also, on that screen I’ve
got loads of information from the time of the day, to
the odometer, trip distance, average speed, max speed, and
battery level in percents. Cadence and loads and loads
of information on there, I’ve even got a stopwatch if I need it. So, this bike has actually
got GPS, a GSM chip, Bluetooth, and an accelerometer. The GPS is used for anti-theft,
so you can set that up so you know where your
bike is at all times. But also for normal usage
like tracking a ride and exporting as a GPX file. The bike also has an accelerometer, so if you fall off this bike, you can set it up so it sends
your phone a notification. If you don’t respond in
a certain amount of time, it will send out an emergency
signal, so clever stuff there. You can get much bigger
screens like the Bosch Nyon that will give you a lot more information like navigation and fitness tracking. The Bosch systems are interchangeable, so you can upgrade to different controls and screens if you wish. Personally, I prefer a much
more streamlined approach. Specialized even go a bit further, you just have a remote up on the bar, have an LED of your battery
life on the battery itself and then they rely on
an app on your phone. The Mission Control app if you want get into much more details. On that remote on the bars you’re gonna find the
walk assist mode as well. That’s really useful when
it comes to the steepest, unrideable climbs where you’ve
got to push your bike up. That really helps you get
the bike up that climb. I also use it in those
situations where I need to change to an easier
gear and I don’t want to risk snapping my chain by putting loads of force through those cranks. They are heavy, they weigh in
at about 20 to 25 kilograms. Almost twice the weight of a normal bike. Now it does come down mostly
to the battery and the motor. But also some of the
components sort of up rated to deal with extra weight and the forces that go through these bikes. You really don’t notice
the weight too much when you’re riding the bikes, while not as much as you
think before you’d ride any bike for the first time. The one place where you
really do notice the weight is when you’re trying
to slow the bike down. That is why they come
fitted with big brakes. This bike has these Magura
MT7’s, big 4-pot calipers, big discs, so 200 mil on
the front, 180 on the rear. That’s something you would normally see on a downhill bike, not
a 150 mil travel bike. (relaxing music) Most e-bikes have easily
removable batteries, but not all. So, why would you want
to take that battery off? Well, leaving it in a freezing cold garage is not gonna help the
health of that battery. It will last much longer if
you keep it nice and warm. Also, sometimes it’s just easiest to take that battery inside to charge. Also, I sometimes take mine
off ’cause I put my bike in the back of my car
and it can be quite heavy trying to get them in there. It’s also worth noting
that e-bikes are too heavy for most car roof racks,
so you might have to run a tow bar rack or put it in
the back of the car like I do. You can’t currently fly
with your e-bike battery so most airlines will carry
up to 180 watt-hour batteries and these are 500’s. So, at the moment you have
to rely on either driving, shipping your battery or
potentially hiring one ’cause it’s sure to get much more popular. (relaxing music) Now, when it comes to
e-bikes specific components, actually it’s not just the buzzword, they are actually designed to deal with the different forces
and weights of the bike. So, DT Swiss have their
Hybrid wheel so the hub and the rim are both beefed up. Tested fully with e-bikes just to deal with the extra weight. You can get different
internals, your forks, also the drivetrain’s a big one. It takes a lot of punishment on an e-bike. SRAM have their EX1 groupset,
it’s only eight speed and that gives them a
chance to have a wider, but chunkier chain so it’s much stronger. Also, the shift will only
go up one gear at a time, and that just stops you from
smashing through those gears, putting loads of power in and potentially snapping that chain. The batteries aren’t cheap, they cost about six or
seven hundred pounds. They do last about a
thousand charging cycles, so they’re likely to actually
last the lifetime of the bike. A nice luxury though is
having a spare battery so you can go out for
those really big days. (relaxing music) Riding an e-bike can be harder work than riding a normal mountain bike. We’ve tested it, so have others. We’ve all came to the same conclusion, a short two hour ride on an e-bike can just be a better workout. Now, your likely for pushing just as hard, you’ll be traveling faster, going further, and getting an all around body workout.
