We carefully selected each and every component we put into the M-Class electric commuter bike. Ariel Rider is passionate about electric bikes – our designers, engineers, and even our office staff have all ridden them in our daily commutes for years now. You can trust that we are experienced ebike enthusiasts who understand the expectations and real-world problems electric bike riders face in daily life. We’re proud to ride a fully-featured electric commuter bike that is not only great-looking, but also affordable, boasting the latest technology available.
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
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.
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.
Ariel M Class
box inside of box
both boxes are double thick cardboard
plenty of large staples to make each rectangle box stiff
ALL parts are heavily protected with redundant foam and bubble wrap
ALL parts are secured with redundant ties
Fork assembled on the frame with quality pieces that are discarded to install the handlebar. A frame from another company had the pieces (headset, cap, spacers, stem, etc.) in a box requiring me to assemble the fork onto the frame.
No need to assemble the fork, just discard the above pieces and slide the stem onto the fork with handlebar already installed on the stem.
Tool Kit: more tools than I needed. This is the FIRST bike/frame that I've ordered that included a toolkit. It has redundancies for pleasant usage.
Spare nuts, bolts and washers. Great for adding accessories or preferred sizing.
Rack already installed. Has nuts integrated into the rack which the spare nuts fit.
The seatpost and stem adjusted to the EXACT fit that my custom $10,000 bicycles have.
The ride without the battery was AWESOME. Comfortable and pleasant.
The bicycle stands on end with the installed rear rack.
With the battery and the assist at 5, you can go everywhere in the highest (7th) gear. I NEVER have to shift and I have a steep hill to climb to get out of my house. I also weigh over 200 pounds.
I need 2nd gear to climb the hill without the battery, but I would probably need 1st gear if I did not go on 50 mile bike (not eBike) rides every other day.
When contacting support, feedback is provided within a day. . .
NOT SO GREAT
. . . I am very happy with the bike, but I’ve had to make adjustments and adapt to the quirks listed below. . .
The 7 speed hub was out of adjustment and shifted in an unusual fashion on my first ride without the battery. This was an easy adjustment once you search for and watch a video how to. And with the battery pack, I do not need to shift.
NO assembly or operating instructions. YouTube videos are for an older model. On the Ariel website, the picture matches the bike I received. I see a different bike in the video.
Installing the stem is not obvious and the video just shows it being done, but NOT how to do it.
Impossible to install the front fender with the bolts provided. I found some spare bolts that allowed installation. The Ariel website video shows installation onto a different fork.
After requesting assembly and operating instructions from
Ariel, I was sent a link to a PDF. These instructions had several errors and omissions. For example, I had problems installing the front fender. There were NO instructions how to install it.
The operating instructions state a 3 button display, then show 4 buttons.
The website states, “Ariel Rider M-class ships with a 20mph speed limiter. This limit can be changed from the screen up to 25mph.” A video and review (http://ebikereviewer.com/index.php/2018/07/13/ariel-rider-m-class-electric-bike/) shows a max speed of 28 mph, the sticker on the bike states 20 mph, the instructions state to set to 15.5 mph and impossible to set above 25. My bike was shipped with a max speed of 34 mph. I can feel full power past 24 mph while pedaling.
The website states: “This means you'll cruise for days and days without charging it.” However, the instructions state that you need to fully charge before each ride.
The gear system is for 27 inch wheels.
In the highest (7th) gear, you can only pedal comfortably up to about 20 mph, not the 28 mph max shown in the electronics video. Note that 27 inches/20 inches = 1.35 and 28 mph/20 mph = 1.4.
In order for it to be geared for 20 inch wheels, it must have a chainwheel with 1.4x as many teeth.
A standard 52 tooth chainwheel would provide the max 28 mph shown in the electronics video.
Because the 38 tooth chainwheel (optimal for 27 inch wheels) is undersized, you can stay in 7th gear all the time, even up most hills. I leave the assist level at 5.
This means that with the undersized chainwheel, you don't need any gears, a one speed gear in the rear will take care of all situations (provided you don't run out of battery).
Claims to have a torque sensor, however, it is not active. The power is NOT proportional to your efforts. It simply puts out a given power level while you pedal at any effort. My other eBike IS proportional, so you feel feedback; the harder you pedal, you can feel more power going to the wheels. No torque until you apply force to the pedals. On the Ariel M Class, as soon as you pedal, you get FULL torque from the motor proportional to the assist level that you set.
The power fluctuates with constant cadence. 70% up a short hill the power seemed to cut out, then come back on. The same occurred on the way back from the store on a flat road. I have to hold power assistance on for smooth operation. Pedaling allows you to go faster (i.e., adds power).
