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.

Great bike for steep climbs

I bought my bike a year ago and really enjoy it. I live on a steep (17% grade in some sections) dirt road and this little bike makes my commute manageable. I switched to knobby tires (meant for a BMX bike, but it works for this one) to make the dirt and gravel sections of my ride a little easier. The bike gets me out of my car, which makes me so happy. I did a lot of research, and there isn't another bike within this price range that can climb the hills I need to climb to get home at the end of the day without burning out a motor. Overall, I really enjoy this bike and I am very glad I made the purchase. I've been recommending it to all my coworkers and friends.

A few things to note:
1) My commute is 27.5 miles round-trip with 3600' of elevation gain. I get one full commute per battery charge, so about 30 miles per charge. This mileage is a bit less than the 45-65 miles advertised, but I recognize that most people do not have so much climbing on their rides.
2) Some of the gears (primarily 4th gears) skip when I'm riding and have done so since I took the bike out of the box. Given that this is an internal hub, I haven't yet figured out how to make the appropriate adjustment so mostly don't use this gear.
3) The instructions for assembling the bike were difficult to find (I didn't see them linked on the website but was able to find them through a google search) and were for an older model of the bike. I was able to follow them, but a few things have changed.
4) I very much appreciate that the bike has 8 gears. The hardest gear doesn't allow me to pedal fast enough on the downhills (again due to the steepness of my ride, which results in speeds upwards of 30 mph), and still I haven't quite figured out the gear/assist tradeoffs for hill climbing. Lower gears mean that the pedaling is easier, but you also get much less assist. I end up leaving the bike in a higher gear (3rd-5th gear) for my steep climbs because the assist is so much more powerful.
5) With the knobby tires that I added, the fenders barely fit. I'd love to see Ariel add an option for purchasing the bike with knobby tires and/or move the fender attachment just a bit higher to make room for knobby tires for those of us who have gravel/dirt on our commutes or rides.

Despite some of the relatively minor issues outlined above, this is a fantastic bike for the price. I very much recommend this bike to help you get out of your car. Better for you, better for our air quality.


I drive semi truck and wanted a way to explore so did some research , I've had this bike going on three years and still going strong .
I ditched the fenders and put bigger tires on it . Thing really scoots .its basically the BMX bike I wish I had when I was a kid

So far it’s all good news.

Only 40 miles on the bike so far but I love it.

Starting at the beginning, after purchasing the bike there was a bit of a delay confirming the order and shipping but that was followed up with a confirmation and a follow up email.

Bike arrived with some signs it had been jostled around in shipping but no damage occurred. Bike and tubing were very well packaged.

Assembly took about an hour. It should have taken 10 minutes but attaching the front fender was extremely difficult due to the bolts being just a hair not long enough. Technically they are long enough but it’s very awkward and required pre-bending some of the plumber style clamp ends. It was comedically difficult given that it was just putting three bolts into holes. Also required an adjustable wrench that was not included.

A spare parts bag was included and a variety of cheap tools which was very welcome.

After the fender issue I was up an running in no time. There are no physical directions in the box and my phone was dead so I had no way to go online to review the setting options for the display controller but figured out the basic operation.

The bike works exactly as you would expect and I had no problem getting up to 20 miles per hour which is definitely fast enough. The gearing is also very usable without turning on the motor. Obviously geared for hills and start and stop riding not speed. For a city bike that’s the way it should be!

Two negatives. The paint job is fine but not as durable as most mass produced bikes. Not a big deal. Just easy to scratch.

The battery meter shows significantly less mileage in the two highest pedal assist levels. Haven’t had time to accurately compare the mileage in level 1 vs 5 but I’d be surprised if level 5 is 20 miles range on moderately hilly terrain with a 175 lbs rider.

There are bosses to attach a water bottle cage but the location on the top of the top tube would make for awkward mounting and dismounting.

Parts and build quality are very nice. Nothing cheap about this at all. The seat is IMO ugly but not uncomfortable. The rear rack came pre attached. I like that it is not part of the frame if it gets damaged or I just don’t want to use it.

The bike is very compact which was why I selected it. Not much longer than a Brompton but much heavier.

My first impression is that the M-Class is easy to handle, I have to carry my bike upstairs and the weight of my older W-Class was wearing on me. Wondering how well the smaller tires will wear. The front shocks allow more dampening than i thought they would. I’ve only ridden it once so I’d rather get back to you in about a month or two with a better informed review.

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.
