Engine Pro 2 Review: A Folding Fat Tire E-Bike That Checks Nearly Every Box

Introduction

The Engine Pro 2 is a folding fat tire e-bike that aims to do a little bit of everything: commuting, errands, weekend rides, and even rougher gravel and off-road duty. It is the successor to a model we spent roughly two and a half years with in a long-term family test fleet, through torrential spring rain, dry 100-degree summers, dusty uphills, deep winter cold, and everything a small Montana town can throw at a bike. The original held up remarkably well, and the new version feels beefier and stronger while keeping the same approach: full suspension, fat tires, and a generous feature list at a reasonable price.

It is worth stating up front that folding bikes in general are not our favorite category. The compromises are real: narrow handlebars, small folding pedals, and a heavier frame to support the folding mechanism. What makes the Engine Pro 2 interesting is that it minimizes most of those compromises better than any folding bike we have ridden, and it does so at a price that makes the folding ability almost a bonus rather than the main reason to buy.

Ride Comfort and Suspension

Full suspension is the headline comfort feature here. A front suspension fork is fairly common on e-bikes, but rear suspension is not, and having both gives the Engine Pro 2 a noticeably smooth ride. On a test ride over a dip in the road, the bike moved while the camera mounted to it stayed steady, which is a good visual demonstration of how much roughness the suspension absorbs. Combined with a comfortable seat that also has springs underneath, dips and bumps largely disappear from the riding experience.

The fat tires add a second layer of comfort. Beyond the obvious grip and traction benefits, wider tires simply ride softer than narrow ones, and they look great doing it. Whether you are riding around town, commuting to work, or cruising near the beach, the combination of full suspension and fat tires makes this one of the more comfortable bikes in its class.

Motor Power and Speed

The Engine Pro 2 is advertised with a 1,200W peak motor rating. Think of that peak figure the way tool brands market voltage: the nominal output is closer to 1,000W, which is at the top of the spectrum for consumer e-bikes. Many municipalities ban anything over 1,000W, and regulations cap throttle speed at 20 mph with pedal assist up to 28 mph, so lower-powered bikes can still legally get you where you are going.

What a lower-power bike will not do is get you there quickly or climb hills without struggling. This is where the higher power output pays off: on a climb, the Engine Pro 2 does not hesitate the way a 500W bike can. There is also a safety argument for strong throttle response. In traffic, being able to hit the throttle and instantly get out of the way of a distracted driver is a genuinely useful capability, and it is one of the more underrated benefits of a powerful e-bike.

Practical Details: Rack, Lights, and Display

The Engine Pro 2 arrives well equipped. There is a good heads-up style color display, comfortable grips with a flat palm rest that lets you lean your weight forward, and a proper lighting setup with both a front light and a rear light that functions as an actual brake light. An included rear rack is a welcome bonus, ideal for hauling groceries, a work bag, or in one memorable test ride, a burger run from downtown back to the office.

For pedaling, a Shimano Altus 8-speed shifter provides smooth, easy gear control, and hydraulic 160mm brakes handle stopping duties.

Battery, Folding, and One Weak Spot

The 52V 16Ah lithium battery is enclosed in the frame, which protects it from weather. The trade-off: you have to fold the bike to access the battery, which is a slight inconvenience, though the enclosed design keeps the pack out of the elements. Charging takes roughly 6.5 hours, which is a realistic figure rather than an optimistic one.

The one genuine weak point is the folding pedals. They are small and rickety, and this is the first thing worth changing after buying. A set of decent standard pedals costs around $30, comes in any color, and is a meaningful upgrade over the folding originals. This is the kind of honest trade-off that comes with any folding design, and it is an easy fix.

Specs at a Glance

• Motor: 1,200W peak (nominal around 1,000W)
• Battery: 52V 16Ah lithium, enclosed in frame, about 6.5 hour charge time
• Top speed: 20 mph throttle, 28 mph pedal assist
• Range: up to about 30 miles (48 km) throttle mode, up to 68 miles (109 km) pedal assist
• Brakes: hydraulic, 160mm
• Gearing: Shimano Altus 8-speed
• Weight: 70 lbs
• Max load: 330 lbs
• Rider height: 5’4” to 6’2”
• Colors: Space Black, Midnight Blue, Mountain Green

A note on range figures: every manufacturer exaggerates to some degree, but this claimed range is a fairly modest exaggeration. You will approach the upper figure by running the fat tires at maximum pressure, which gives the hardest roll and the best mileage at the cost of some comfort. Soft, low-pressure tires eat into range, so as the saying goes, your mileage may vary.

At 70 lbs, this is on the heavier side of the typical 50 to 70 lb e-bike range, and the folding mechanism is the reason. The frame has to be more robust to allow the fold, and even in aluminum that adds mass.

Price and Availability

The Engine Pro 2 normally lists at $1,400 and was on sale for $1,300 at the time of testing, with a coupon code available if you order accessories. There was also a small discount code for new customers that could be stacked on top. Accessories include a trunk bag, a phone holder, and other practical add-ons.

Durability and Long-Term Impressions

This is the strongest argument for the Engine Pro 2. The predecessor spent about two and a half years in a long-term test fleet used daily by three kids in Montana, an environment with torrential spring rain, dry and dusty summers above 100 degrees, steep uphills and downhills, trips toward Yellowstone and through the Crazy Mountains, on-road and off-road use all over town, and winters that dropped to around -40 degrees with snow. The bike handled all of it.

The company is not one of the biggest names in the industry, but based on this long-term track record, the products hold up. The Engine Pro 2 feels like the same formula with more presence: beefier, stronger, and better finished.

Who Should Actually Buy a Folding E-Bike

The honest answer: if you do not need a bike to fold, you probably should not buy a folding bike. The handlebars are narrow by necessity, the folding pedals are mediocre, and if you have a truck with a rack, a full-size bike is easier to live with.

But there are real exceptions, and the Engine Pro 2 makes a convincing case for them. If you live in an apartment, the folding frame and fold-down handlebars let it occupy a corner without dominating the room. If you need to fit a bike in a car trunk, folding is a necessity. And even if you never fold it, the bike is still slightly shorter and more compact than a full-size equivalent.

The counterargument is everything you get for the price: full suspension, fat tires, Shimano Altus 8-speed gearing, hydraulic brakes, a high-capacity 52V battery, an included rear rack, and a full lighting setup. It would not be surprising for someone who does not strictly need the folding function to look at that feature list at this price and buy it anyway. Every job has a tool, and the question is whether this is the right tool for yours.

Conclusion

The Engine Pro 2 is one of the best folding e-bikes we have ridden, and comfortably the best we have seen at this price. The folding pedals are worth replacing on day one, the battery access requires a fold, and the bike is heavier than a non-folding equivalent, but those are the only meaningful complaints. Full suspension, fat tires, solid power, a well-equipped feature list, and a proven long-term durability record from the predecessor make this an easy recommendation for apartment dwellers, car-free commuters, and anyone who wants a single do-everything e-bike, folding or not.
