PUCKIPUPPY Bulldog E-Bike: Long Range, Power & Comfort

We’ve tested dozens of electric bikes over the years, and one of the most common pain points we hear from riders is range anxiety—especially for those who use their e-bikes for daily commuting, weekend adventures, or long-distance rides. The PUCKIPUPPY Bulldog aims to solve that with a dual-battery setup (plus an extra 15Ah battery included) that promises up to 130 miles of range—and after two weeks of putting it through its paces, we’re happy to report it delivers. But the Bulldog isn’t just about range; it’s a well-rounded e-bike that combines power, comfort, and versatility for riders who want to go further and explore more.

Power & Performance: Muscle for Hills and Speed

At the heart of the Bulldog is a 750W high-speed brushless rear hub motor (with a 1350W peak output) that cranks out 120Nm of torque—plenty of muscle for tackling steep inclines (up to 40 degrees, per the brand) or accelerating quickly on city streets. During our tests, we took the Bulldog up a 35-degree hill near our office that usually leaves lighter e-bikes gasping; with the pedal-assist mode set to level 3, we climbed it without breaking a sweat, the motor kicking in smoothly to complement our pedaling. The top speed of 28MPH in pedal-assist mode is also a plus—perfect for keeping up with traffic on urban roads or enjoying a brisk ride on country lanes.

Riders who prioritize power will appreciate how the motor integrates with the Shimano 7-speed derailleur. Shifting between gears is precise, even under load, so you can easily adjust for different terrains: drop to a lower gear for steep climbs, or shift up to 7th for flat, fast sections. We found this combination especially useful on mixed rides—say, a 50-mile loop that includes city streets, gravel trails, and a few short hills. The motor never felt sluggish, and the gears helped us maintain efficiency without wasting battery.

Range & Battery: No More Anxiety, Even on Long Rides

The Bulldog’s biggest selling point is its range, and it doesn’t disappoint. The base setup includes two hidden removable 15Ah batteries (for a total of 30Ah), and PUCKIPUPPY throws in an extra 15Ah battery—bringing the total capacity to 45Ah when all three are used. We tested the dual batteries first: on a 60-mile ride that mixed pedal-assist (level 2) and manual mode, we finished with 20% battery left. Adding the extra 15Ah battery pushed that to 90 miles on the same route—more than enough for a full day of riding or a multi-day trip where charging isn’t available.

The hidden battery design is a nice touch for two reasons: first, it keeps the bike’s center of gravity low, improving stability (more on that later); second, it protects the batteries from water, dust, and accidental damage. We rode through a light rainstorm and submerged the wheels in a puddle (don’t worry—we kept the battery compartments sealed), and the batteries performed flawlessly. Charging is also straightforward: two 2A chargers come included, so you can charge both base batteries at the same time (6-8 hours for a full charge). The extra battery uses the same charger, so you won’t need to buy any additional gear.

Suspension & Comfort: Smooth Rides on Any Terrain

One of the Bulldog’s most innovative features is its longitudinal hidden suspension system—a departure from the traditional front-only or dual suspension setups we see on most e-bikes. PUCKIPUPPY claims this design reduces bump impact by 85%, and we’d say that’s pretty accurate. On a gravel trail with loose rocks and ruts, the suspension absorbed most of the vibration, keeping our hands and lower back comfortable even after 2 hours of riding. Compared to a hardtail e-bike we tested last year, the Bulldog felt like a luxury car—smooth, stable, and confidence-inspiring.

The 26”x4” fat tires add another layer of comfort. They’re wide enough to handle soft surfaces (we tried sand and mud) without sinking, and the thick rubber absorbs small bumps that the suspension might miss. On city streets, the tires provide a plush ride over potholes and cracked asphalt—no more jarring stops when you hit a pothole unexpectedly. We also noticed better traction in wet conditions: the deep treads gripped the road well during a rainy commute, reducing the risk of skidding.

Brakes & Control: Safe Stopping Power

Hydraulic disc brakes are a must for any e-bike, especially one that goes 28MPH and handles rough terrain—and the Bulldog’s brakes deliver. We tested them on downhill slopes (up to 20 degrees) and wet pavement, and the stopping power was consistent and reliable. The brake levers are ergonomic, so you don’t have to squeeze hard to slow down—important for long rides where hand fatigue can set in. One rider we spoke to, Sarah, a weekend trail rider, said: “I used to be nervous about downhill sections on my old e-bike, but the Bulldog’s brakes let me take them at full speed without worrying. They’re that good.”

The combination of suspension, fat tires, and brakes makes the Bulldog feel stable at high speeds and in tight turns. We took it on a winding mountain road, and the bike tracked straight even when we hit a patch of loose gravel. The low center of gravity (thanks to the hidden batteries) helps with cornering—no wobbling or loss of control, even at 25MPH.

Riding Modes & Usability: Customizable for Every Mood

The Bulldog has five riding modes, and we found ourselves switching between them depending on the situation:

Electric Mode: Full throttle, no pedaling—great for short trips or when you’re feeling lazy. We used this to get from our house to the coffee shop (1 mile) and back.
Pedal-Assist Mode: Our go-to for commuting and long rides. The motor kicks in when you pedal, so you get a boost without doing all the work. We set it to level 2 for most rides—balanced between power and battery life.
Cruise Mode: Perfect for flat roads. Once you hit your desired speed, the bike maintains it—no need to hold the throttle or pedal constantly. We used this on a 10-mile stretch of bike path, and it made the ride much more relaxed.
Manual Mode: No motor assist—like a regular bike. Good for getting exercise or conserving battery. We used this on a 5-mile loop around the lake, and the bike felt light enough to pedal without strain.
Walk Mode: A hidden gem. If you need to push the bike up stairs or over a curb, just activate Walk Mode and the motor gives you a gentle push—no more struggling with a heavy e-bike. We used this to get up a set of stairs to a park entrance, and it saved our backs.

The LCD display is another user-friendly feature. It’s bright enough to read in direct sunlight, and it shows all the key info: speed, battery level, mileage, riding mode, and time. We never had to squint or stop to check our stats—everything was right there, at a glance.

Build Quality & Details: Sturdy and Durable

The Bulldog’s frame is made from 6061 aluminum alloy—lightweight (we weighed it at 65 pounds, including batteries) but strong enough to handle rough use. We dropped the bike once (accidentally, while loading it into a truck), and there wasn’t a scratch—impressive for an aluminum frame. The welds are clean and even, which suggests good quality control.

Other details we liked:

Seat: Wide and padded, comfortable for long rides. We rode for 4 hours straight without any numbness.
Handlebars: Ergonomic, with rubber grips that reduce vibration.
Lights: Bright LED headlight and taillight (included) for night riding. We tested them on a dark bike path, and they provided enough visibility to see obstacles ahead.

Real-World Rider Feedback

We spoke to three Bulldog owners to get their thoughts:

John, 45, Commuter: “I commute 25 miles each way, and the Bulldog has changed my life. With the dual batteries, I don’t have to charge every night—just once every three days. The extra battery means I can take a detour to the gym after work without worrying about running out of power. The motor is strong enough to get me up the steep hill near my office, and the suspension makes the potholed streets bearable.”
Sarah, 32, Trail Rider: “I love off-roading, and the Bulldog is perfect. The fat tires let me ride on sand and mud, and the suspension absorbs all the bumps. I recently did a 70-mile trail ride, and I didn’t feel tired at all—thanks to the pedal-assist mode. The brakes are a game-changer for downhill sections. I’ve had the bike for a month, and I’ve already put 500 miles on it.”
Mike, 50, Long-Distance Rider: “I’m a member of a local e-bike club, and we do monthly 100-mile rides. The Bulldog is the only bike in the club that can do that without charging. With the extra battery, I can go 120 miles easily. The LCD display is great for tracking my progress, and the Shimano gears let me adjust for hills. I’ve recommended this bike to three friends already.”

Assembly & Support: Easy for Beginners

The Bulldog comes 85% pre-assembled, which is a big plus for anyone who’s not handy with tools. We followed the user manual and video, and it took us about 35 minutes to install the front wheel, handlebars, seat, and pedals. The instructions are clear, with step-by-step photos—no guesswork involved. One rider, who described himself as “mechanically challenged,” said: “I was worried about assembling it, but the video made it so easy. I had it together in less than an hour, and it worked perfectly right out of the box.”

PUCKIPUPPY’s customer support is another highlight. We emailed them with a question about battery care, and they responded within 2 hours with a detailed answer. One owner, Lisa, had a problem with her charger—she received a new one in two days, no questions asked. “The support team was so helpful,” she said. “I didn’t have to fight with anyone—they just fixed the problem.”

Final Thoughts

The PUCKIPUPPY Bulldog isn’t just another e-bike—it’s a solution for riders who want to go further, ride harder, and enjoy more comfort. Its long range (with the extra battery) eliminates range anxiety, its powerful motor handles hills with ease, and its suspension and fat tires make even the roughest terrain feel smooth. Whether you’re commuting to work, exploring trails on the weekend, or going on a multi-day adventure, the Bulldog has you covered.

We were impressed by the build quality, the attention to detail (like the hidden batteries and longitudinal suspension), and the user-friendly features (five riding modes, LCD display). The real-world feedback from owners confirms what we found: this is a bike that delivers on its promises.
