2020 Model M-Class Electric Commuter Ebike

Slim in size, huge on performance.
The ultimate urban cycling experience.

You'll love the spirit of Ariel Rider’s M-Class electric commuter bike. Selected as the best small-sized ebike by eBikeReviewer.com in 2018, M-Class is much more than a regular electric folding bike look-alike as it offers the best of every feature needed. This is why M stands for maximum performance at minimum dimensions.

Starved for space at your office or home? Fret not. The M-Class is the best electric commuter bike for anyone who relishes the freedom of cruising when space is at a premium. It’s a smaller ebike, but perfectly suitable for people of all heights, thanks to an adjustable seat post and

M-Class is not only lightweight and compact, it also is the
most powerful among all such compact eBikes (i.e. mostly folding electric bikes). M-Class maximizes your savings, too! Check out this objective comparison of electric bikes costing up to $4,000.

What's New?

New Mid-Drive Motor

We're using a new generation of mid-drive motors with even higher torque than before, to ensure you climb up the hills effortlessly.

For a smoother ride, now M-Class comes with gear sensors, which detect when you're shifting gears and cut off the motor power for a smoother gear change.

Gear Sensor
Brakes with Motor Inhibitors

It's not common to have motor inhibitors on brakes in mid-drive electric bikes, but we're not here to do the common thing. Your safety comes first.

Front Shock Absorbers

Every year we upgrade certain parts on our ebikes according to the feedback we receive from our clients.

The only request we got was the front shock absorbers, so we changed the front forks!

New Display with USB Port

The new screen is not only looking better than the previous one, it also packs a USB port to charge your electronics on the go.

A longer rear rack

The optional rear rack is now larger to carry more stuff with you.

With optional baskets that fit right on the rear rack, you can haul a lot with the new M-Class.


Go the extra mile

Most city commutes are less than 5 miles. We’ve equipped our smallest electric bike with a high-capacity 12 Ah Samsung battery pack.

It's simple to remove, so you can charge it effortlessly at home, office, or anywhere. This compact battery will give you a truly awesome range of 45 to 65 miles per charge. This means you'll cruise for days and days without charging it.

Our pledge is to provide the highest quality with the greatest design. We will never cut corners on the most important components of your electric bike.

This battery has superior capacity for that extra range you when you need it most and it only weighs around 7 lbs!

Astonishing torque

The mid-drive motor offers smooth riding experience - you won't feel like you're riding an electric bike at all.
This mid-drive motors provide one of the highest torque in the market.
M-Class is equipped with the 48V 500W mid-drive motor sporting 98 Nm torque.

Key points:

  • The mid-drive motor increases the torque applied to your rear wheel. This translates to remarkably more power, especially when riding uphill. Compared to hub motors, it's a breeze.
  • Mid-drive motors are very energy-efficient compared to hub motors, so you’ll enjoy far longer-range with a smaller battery.
  • A mid-drive motor is in the middle of the bike, where the crank is located. This way, weight is uniformly distributed and the center of gravity doesn’t change.
  • Unlike other mid-drive options in the market, M-Class is also equipped with a throttle for those longer rides where you don’t want to pedal anymore.


45-65+ miles per charge (estimated)


4-6 hours

Cargo Capacity

Don't let the size of our M-Class fool you. This bike is an urban workhorse. With the rear rack and optional front basket, you can carry groceries, your gym bag, or even your child all at the same time!


One huge problem we hear about from commuters is weight. Riders are concerned that bikes are too heavy, especially if they live or work in high rise buildings.
We achieve this with advanced frame production techniques, combined with a higher capacity battery using fewer cells.

It'll surprise you how easy it is to lift and carry your M-Class with only hand since it weighs only 47.5 lbs.

Adjustable Stem

The versatile and effective Promax Adjustable Handlebar Stem offers just the right fit. The handlebar stem is adjustable from 90 to 160 degrees and includes spacers for 22.2 and 25.4- millimeter stems. It boasts an alloy for enhanced durability. The seat height also adjusts easily in mere seconds. And did we mention -no tools required! For couples who want to share their ebike, these smart features make quick work of swapping out.

Full Fenders

Not all of us live in sunny SoCal. The M-Class comes equipped with front and rear full coverage fenders to keep you clean and dry if you happen to ride through puddles.


Suspension Seatpost

No city street is a smooth, well-maintained Formula One racetrack. Our adjustable suspension seat post adds yet another level of comfort to your commute, smoothing out those rough roads. At the end of the day, M-Class details like this transform your commute into a gentle breeze.

Maintenance Free 7-Speed Gears

Repairs and maintenance are no fun. We're riders just like you, and we know the struggle. This is why we’ve designed all our ebikes to require minimal maintenance.
The M-Class's Shimano 7-Speed Inner hub gears are extremely durable and highly reliable.
The gears are all hidden inside, protected from the elements and physical damage. Having no external derailleur makes them three times more durable than traditional gears. Learn more about inner hub gears here.


We're confident that Ariel Rider's M-Class is the easiest ebike to move about on, either riding it or walking it.
From top to bottom, M-Class is designed to be extremely easy to carry. An unobtrusive, but very useful handle under the saddle will help you pull your electric bike out of tight spaces, without needing to be right next to it.


Hydraulic Disc Brakes

Tektro Hydraulic Disc Brakes are designed to provide the best brake performance for the fastest ebikes. Be confident of their performance regardless of your speed or weight, and especially going downhill.

LED Headlight

The Spanninga LED headlight ensures that you can see and be seen at night in any road conditions.

This LED headlight is powered by the main battery of the ebike.

Reflective Sidewalls

We want to make sure our riders are visible at all times and from all angles.

That’s why all our tires have reflective sides.

Rear Light

Safety is a major concern for us. That’s why all M-Class ebikes are equipped with LED rear lights.

These LED lights are powered by the main battery of the ebike.

Customer Reviews

Based on 160 reviews
Love my bike

Shipped well. The video for putting the fender on needs to be re-done. Also, putting the fender on was very difficult once we figured out how to put it on.
Great bike easy to ride and very lite weight. I have had a few EBike and this is the best one I have had. I live in The Villages where you ride up and down tunnels, bridges and golf cart paths. Very Smooth ride and fun.

Sweet lil M

As per other reviews on technical aspects, I would have to agree without any previous experience to contrast. I find this bike powerful and quick, and fun to ride. I researched quite extensively and could've saved lots of money buying local (Vancouver, Canada) but the power, size, and weight of my lil M kept it at the top of my list. Also the style. I love the style.

(Please continue your efforts on the customer service end of your company;)

Rave Reviews

We needed 2 bikes so spending that much required lots of research. I was an amateur racer with a Colnago frame and Campagnolo parts. I knew a lot about bikes a very long time ago. We got lucky and found ours at a full-service dealer. He had the best price anywhere and no assembly necessary. The website cannot do justice for what a perfect design it is for anyone. My wife and I are retired. We are not as nimble as when we were younger. I knew that a smaller bike would be easier to handle (think BMX racing). What a difference! The turning radius and handling are so much smoother and easier than the bigger ones. A 7-speed hub with no derailer (BIG difference in shifting, much less maintenance) is plenty of power assistance so pedaling is no problem. It's smaller (travel storage) and lighter so we didn't see why we would want a big one. The front basket is a must. Just drop a backpack in it to take your battery and all your belongings with you. Batteries are a target item. Thieves stole my bike stuff (and bikes) many times over 40 years ago...and still do. They use battery-powered (irony?) cut-off saws for locks now. We are buying a van for storage instead of a truck. Again, thieves have made eBikes a major target. This strategy will help while using it with our travel trailer. Do your homework and you will discover the weight distribution, power usage, and torque advantages of mid-motors. The seat was good quality butt we changed it to the bigger, more padded saddle for obvious reasons. The color is more gold than orange and is better than pictured on this site. My wife got the blue one and the pair together is stunningly stylish. Oh yea, and don't forget the throttle assist and hydraulic brakes. Perfect. Hat's off to the designers!

Feel Confident about Ariel Rider

If you are patient with Ariel Rider--patient with their orders and with their replies to queries--you will find that this is an ethical company with quality bikes. My m-class arrived in eight days and was easy to assemble, once I consulted the YouTube videos. (They should include more clear reference to their online resources with the bike.) Ariel kindly helped me with a mistake I made with a discount code and worked it out for me. Everything on the bike works great, and it is powerful. The pedal assist works wonderfully--far better than my last bike. The throttle works fine, but the pedal assist makes it an afterthought. With the speed limit lifted, the bike cruises effortlessly at around 22-23 mph, chewing up all NYC hills and bridges. It could easily go faster, which brings me to my one complaint: the gearing. The bike needs higher gears, and it has too many low gears. Ariel Rider, please enlarge the chainring and/or reduce the rear gearing size! It would also be great if Ariel included info on the bike's chain to make it easier for us to do this on our own. I think most serious riders will wind up doing this. Nevertheless, this bike remains the best deal in its class, and I can vouch for the c-class too, which uses mostly the same parts but with a different frame. (Both bike's frames are a bit large for petite people.) Trust this company.

M Class bike and Ariel bikes awesome to deal with

Bike was delivered swiftly and in excellent condition. Assembly was straight forward ( I have plenty of bikes). Given that the M Class model has seen some updates perhaps you could include a card with the bike that indicates the correct YouTube address? I was watching a video for a previous year model and was a bit confused at first. No biggie though. Otherwise, my front brake rotor was warped to the point that I couldn’t properly center it in the brake unit. Luckily I live near a bike shop and they had the rotor tool to straighten it out.

Functionally, the bike is AWSOME! Frankly I’m surprised how fast I can go on it. I’ve been using it for cargo trips.
