What’s up, everyone! Brent here. I know a lot of you have requested some reviews on M2S bikes, so I’m very excited to be reviewing the M2S All Terrain R750 today. This is an off-road capable electric bike with a plethora of frame sizes and colors to choose from with a starting price of $1,799. At this price point, the R750 offers a fair deal, including a 750 watt geared hub motor, a hefty 16 amp hour battery, hydraulic disc brakes, a competent Shimano Acera derailleur, a sturdy rear rack, front suspension with 100 mm of travel and beefy 4” wide fat tires. There’s also the option to downgrade to a smaller 10 amp hour battery to save $150, or for an additional $250, there’s also the option to upgrade to a whopping 21 amp hour battery. M2S offers the R750 in two different frame types, four different frame sizes and five different colors. The one I received is a traditional high-step 17” frame (the Medium), but there’s also an 18” step-thru frame, a 19” high-step frame and a 22” high-step frame. My bike was gloss blue, but there’s also the option to go with white, green, black and grey. Whew! That’s a lot of options to go through, but options are a good thing here as it really lends itself to riders of nearly all heights and sizes, as well as personal taste and needs with the many colors and battery options.
M2S is a direct-order only company that only delivers to the United States. Unfortunately, those outside the U.S. are going to have to miss out here unless you’re able to find a used one online somehow. Being direct-order only means M2S doesn’t have any physical brick-and-mortar shops to let potential customers check out the bikes in person and give them a test ride. Normally I’d call this one of the downsides to direct-order only, and technically it really still is a downside, but here there’s at least the option to pick from one of the many different frame sizes and styles. So hopefully everyone will be able to find something that fits them. Another potential pitfall of direct-order only companies is a communication barrier, which thankfully doesn’t exist with M2S at all. In my experience the customer service was prompt to answer the phone, knowledgable about their products and quite friendly. I called from several different numbers to get a feel for this. The last real potential pitfall that comes along with direct-order only companies is mismatched parts or difficult assembles. Again, that wasn’t the case with the R750. In fact, it was one of the easiest electric bikes I’ve assembled so far and only took me about 20 minutes from unbox to riding. There were a few packaging details that I REALLY appreciated here as well. First of all, the zip-ties weren’t overly tightened and they weren’t overly thick. This may seem like a small detail, but I use very small scissors to cut the zip-ties when I unpack these bikes to really try to avoid scratching the paint, and when the zip-ties are overly large or unnecessarily tightened, it really makes rather difficult (and if I’m being completely honest a little painful on my thumb). The other small detail I really appreciated about M2S’ packaging was that the tires came pre filled to the correct PSI! Again, this isn’t a huge deal, but it was just nice to be able to slap on the front tire, handlebars, front fender and battery and get to riding. Overall, assembly was a very, very pleasant process for me. Oh, I suppose we should talk about the potential upside to direct-order only as well. :) With direct-order only I’ve found the prices to be far more competitive than other similar bikes sold in dealers. This makes sense given direct-order only requires less overhead — no physical shops, less utilities; fewer employees. This stays true with M2S in my opinion. The R750 feels fairly priced for what it offers, and especially given the multitude of frame, color and battery options. Right, let’s talk about the specs!
Driving this bike to a top throttle only speed of 20 mph (or 28+ mph in Off Road Mode) and pedal assist speed of 28 mph (or 33+ mph in Off Road Mode) is a Bafang 750 watt geared hub motor in the rear wheel with 80 Newton meters of torque. M2S has this motor custom geared for top speed, and it shows. This motor has a smooth output of power all the way up to about 26 mph. Traditionally, I find Bafang motors have quite a bit of oomph at the low and mid rpms but start to fizzle a bit around 20 mph. Here, it’s almost opposite. Off the line, the R750 is surprisingly sluggish for a 750 watt motor with 80 Newton meters of torque. However, and this is a big “however,” it begins to really find it’s power band towards the mid and higher RPMs, making getting up to around 26 mph on flat ground without pedaling incredibly easy. I’m a 185-pound rider who carries around 30 pounds of gear and I was still able to reach these speeds. I haven’t been able to do a full range test on this, but I suspect keeping it wide open will devour the battery. Thankfully, the standard size if 16 amp hours, and there’s always the option of upgrading to the 21 amp hour battery, or simply going easy on the throttle and keeping it in a lower pedal assist setting. With the fat tires and relatively long 710 mm handlebars, this bike feels quite stable at top speed and seems like it would do well at zipping through the city alongside traffic. Of course, with a top speed of 28 mph, or 33+ mph in Off Road Mode, the R750 is at best a class 3, and at worst a class 4. This means it will likely be illegal to ride in many areas. I’d strongly advise checking local laws before hitting the open roads with this bike, or at least consider dropping down the top speed in the settings. But on private property or an OHV park, this thing would be super fun. With the top speed here the R750 really feels more like a scooter or moped to me, especially given the gearing ratio: There’s a 36 tooth chainring up front and an 11-32 spread in the back. This feels more like a mountain bike gearing to me, but the custom motor gearing towards high speed screams paved roads. At speeds beyond around 20 mph I start to feel like I’m really beating eggs. The R750 has a 12-magnet cadence sensor that activates very quickly with just a fraction of a turn of the cranks, though the cutoff has a bit longer delay. Thankfully, this can be overridden with the motor inhibitors by depressing either of the brake levers.
Powering the R750, the headlight and the display is a 48 volt 768 watt hour locking, removable Lithium-ion battery that’s semi-integrated into the downtube. Both the charging port and key port are at the top of the battery and are positioned well clear of the cranks, so this should prevent interference if the pedals are accidentally moved while it’s charging or while the key is inserted. Again, there’s a handful of different options with the R750 as far as battery capacity goes. It comes standard with the 16 amp hour battery, but there’s also the option of downgrading or upgrading to the 10 amp hour or 21 amp hour, respectively. I estimated the minimum and maximum ranges at 20 miles and 60 miles simply because of the high top speed and powerful 750 watt motor. The range here, like with all electric bikes (and electric vehicles in general) is really going to come down to individual rider weights, environmental conditions, type of terrain being tackled and most of all, the level of pedal assist and/or throttle being used. Since the R750 does top out at pretty high speeds and because it has huge 4” tires that have a high rolling resistance, there’s the potential to get low mileage out of the battery here, but on the flip side, the battery can of course be conserved by using the throttle sparingly and keeping it in a lower pedal assist level. The display on the R750 is sleek and provides all the necessary feedback to get a good feel of the electronic levels on the bike. Though it’s not removable or adjustable without tools, I was able to clearly see the display even in direct sunlight. Of course, there’s still the risk of it getting scratched up if the bike is left at a bike rack. The charger for the R750 is a 5 amp charger which is quite a bit more powerful than the typical 2 amp output chargers. This is great since the standard battery capacity is 768 watt hours and should serve to charge it to full capacity in just a few hours. The charger also has an integrated fan and I was impressed at just how cool it stayed even after a full charge up.
A long press of the power button brings the R750 to life and reverts the display to the factory settings of pedal assist level one and the backlight and headlight off. It would be great if the display had a memory to save the settings that were left on it before it was turned off. It would also be great if it had a full size USB Type A port to power accessories, but hey, what can you do? The throttle on this bike is always live, even in pedal assist level 0, and gives me full power on tap regardless of assist level. I LOVE this as it allows me to keep it in a lower pedal assist level to conserve battery (and maybe get a little bit of a workout) but still be able to use the throttle to zoom up a hill or across a crosswalk if I need to. I also use this ability to assist the bike up stairs, which is quite handy for me since I live on the second story. The independent button pad on the left is also simple with only three buttons, +. – and power. The simplicity makes it easy to operate, and the tactile click with each button press gives me reassurance that it has been depressed without needing to double check the display. My only concern here with this button pad is the design. The + and – buttons have a slight gap between them and the button pad and they could get snagged with a long-sleeved shirt or jacket, potentially ripping off a button entirely. The headlight on the R750 is a Spanninga kendo+ and it puts out enough light to increase visibility in low light conditions, but the beam pattern is too striated and unfocused to provide enough usable light to navigate a path at speeds above a few miles per hour. On the up side though, it is integrated into the electronics so there’s no battery to swap out and it can be toggled on and off with the button pad. There’s also a small red light beneath the saddle and another one at the back of the rear rack, but both these are independent. Overall, the front and rear visibility on the R750 is pretty good, but and while there are reflectors in the spokes there’s no reflective sidewall so lateral visibility is a bit compromised. I think the gloss finish on the paint should help reflect light pretty well though. The R750 also has motor inhibitors that activate whenever the brake levers are depressed and instantly cuts power to the motor. This is a great safety feature to help ensure the shortest possible stopping distance… which is hugely important given how fast this bike can go.
Overall, this bike is really fun to ride. The fat 4” wide tires and long 710 mm handlebars make for a stable ride even at high speeds and it feels like this bike just WANTS to stay upright. That being said, it’s still relatively nimble even with its hefty 69 pound curb weight. I didn’t feel any frame flex with the R750 and the MOZO suspension with preload adjust and compression clicker with lockout along with the massive air volume of the tires does a good job of providing a pretty soft ride on-road, and decent ride off-road. I appreciate the ease of assembly with this bike and the attention to detail with packaging, and I also dig that some of the wires are internally routed. Speaking of wires, M2S did a great job with their cable management and it looks like they also took great care to make everything as clean and tidy as possible. Life is too short for messy wires. The frame lends itself to riders with shorter inseams like myself thanks to the downward swooping top tube. It looks like M2S tried to get the rear rack as far back as possible, but even still the saddle won’t drop all the way, leaving about three inches of seat post. This unfortunately does increase the minimum saddle height. I also dig that this bike is rocking hydraulic 180 mm disc brakes in the front and rear, that it has thicker spokes in the back, a Shiano Acera derailleur and just overall clean look. I also love the option of frame sizes and styles, and the many color options, but the fenders are plastic and do rattle a bit, especially the rear fender since it attaches only to the seat post and not the frame. The R750 feels like a great choice for those who want a full-size electric bike that can go off-road or on, and has plenty of power on tap to reach high speeds. I do want to caution again though that in some configurations this bike may be illegal to ride on public roadways. I want to thank M2S for partnering with me on this review and if you have any questions, please feel free to leave a comment here or on YouTube and Court and I will try our best to answer it. Thanks, folks and if you’re going out to ride, ride safe and have fun!
- Tons of options for frame sizes, frame types, colors and battery capacities means there’s pretty much a version of the R750 for everyone
- Long handlebars provide a wide grip and plenty of stability, which is great given the high speeds this bike can reach, the fat tires and rigid frame further add to the stability
- Hydraulic brakes with 180 mm discs offer plenty of stopping power, brake levers are adjustable reach and be customized to each rider’s preference, depressing either brake lever also activates motor inhibitors and cuts power to the motor, ensuring the shortest possible stopping distance
- Cable management is on point and much of the wiring is internally routed, both protecting the wires getting snagged and making for a clean looking bike
- Display is easy to read in direct sunlight and offers pertinent information on the bike’s electronic status, almost everything can be adjusted in the settings as well, including top speed and a password
- Independent button pad is simple and easy to use, buttons provide tactile feedback when depressed so riders can be confident it was actually depressed without having to verify on the display
- Suspension has 100 mm of travel, preload adjust and compression clicker with lockout, does a good job of providing a smooth ride on-road and allows for moderate off-road use as well
- Fat 4” wide tires have huge air volume which adds to the cushy ride and also provides a wide tire patch for tons of traction, this is especially good news for riders who want to take the R750 off-road through soggy terrain, they can also be aired down to 5 PSI for an even larger tire patch
- Integrated headlamp is wired into the electronics and battery, so there’s no battery to replace and they can also be toggled on and off with the independent button pad
- Battery is semi-integrated into the downtube to make for a slimmer profile, locking and removable so it can be charged on or off the bike, key doesn’t have to be left in to operate, has quick batter level readout on the battery itself, charging port and key port are located on the top and are well out of the way of the cranks
- Selle Royal saddle with gel insert is comfy and just the right blend of active and relaxed, saddle also comes with an independent red light with blinking and steady on functions, also has quick release so saddle height can be adjusted on the fly without tools
- Double-sided plastic chain guard helps prevent the chain from slipping off towards the inside or outside, also offers some protection against strikes
- Comes with a rear rack four attachment points, rack feels sturdy and has a bar to place a bungee to help keep cargo secure, another independent taillight is located at the back of the rack with a steady on function
- Shimano Acera derailleur is a few steps above the Tourney, steel derailleur cage helps protect the derailleur from damage and also helps protect the power cable from damage as well
- Rear wheel has thicker spokes than the front wheel to help compensate for the motor, rims are punched out to help reduce weight
- 1 Year comprehensive warranty is pretty good and covered everything on the bike, including electronics and battery
- M2S customer service promptly answers the phone and are kind and knowledgeable about their products
- Assembly is incredibly easy and M2S took great care in designing how their bikes are packaged, including easy to cut zip-ties that aren’t overly thick or tightened, and they even pre-pressurized the tires!
- Grips aren’t locking and are subject to spinning under heavy torque, given that this bike is designed with off-road use in mind, this could result in an accident
- Display isn’t adjustable or removable without tools, making adjusting it for glare time consuming and also leaves it subject to getting damaged when the bike is left at a bike rack
- Buttons on the independent button pad are susceptible to breaking if snagged by a long sleeve shirt or jacket
- Headlight is mounted on the arch of the suspension, this makes it unsuspended weight and it will bounce around more compared to a mounting point on the frame itself
- Plastic fenders rattle a bit, especially the rear fender which only attaches to the seat post and has no attachment points to the frame itself
- Saddle is obstructed by the rear rack and the rear fender, which increase the minimum saddle heigh, this might make it more difficult for riders with shorter inseams to place their feet flat on the ground while still in the saddle at a complete stop
- Gearing feels a little off given the high top speed and beyond 20 mph it feels like I’m beating eggs to try to keep up
- Taillight isn’t integrated to the electronics, no increased brightness with braking so vehicles and other riders behind the bike might not be able to tell it’s slowing down, also means the batteries will have to be changed when dead
- 4” wide fat tires have a huge tire patch which results in increased drag and road noise at higher speeds, this can eat into the battery when pushing the bike to its limits, also no reflective sidewall which compromises visibility in low light conditions
- Motor is geared towards high speed so the torque at lower speeds isn’t as powerful as other 750 watt motors
- Direct-order only means there’s no way to try before you buy, also means the customer must assemble the bike themselves or pay to have a local bike shop assemble it
