The Puckipuppy Bulldog Pro is a dual-battery, full-suspension fat-tire ebike built for riders who care more about real range, comfort, and off-road stability than shaving every pound. It pairs a 750W rear hub motor (1350W peak) with a 48V 30Ah battery system (two 48V 15Ah packs), 26″ x 4.0″ fat tires, hydraulic disc brakes, and a torque-focused assist system tuned for mixed terrain.
On paper, Puckipuppy positions the Bulldog Pro as a true long-range machine, with a claimed 80–130 mile range, Class 3 performance (up to 28 mph with pedal assist), and a 400 lb payload rating on a 6061 aluminum, full-suspension frame.

Geometry (Reference Data)
The Bulldog Pro uses a single frame size designed to fit a wide range of adult riders.
| Measurement | Bulldog Pro Numbers |
|---|---|
| Recommended rider height | 5’4″ – 6’6″ |
| Reach | 26.3″ |
| Head tube length | 7.5″ |
| Wheelbase | 50.4″ |
| Standover height | 32.9″ |
| Handlebar height | 44.1″ |
| Min saddle height | 36.4″ |
| Max saddle height | 39.8″ |
In practical terms:
- Most average-to-taller riders will find a workable fit.
- Shorter riders near 5’4″ should pay attention to the 32.9″ standover and minimum saddle height, especially if they prefer a flat-foot stance at stops.
👉 If you’re near the edges of the height range, compare these numbers to a bike you already ride comfortably before ordering.
Motor, Speed & Power Delivery
Under the skin, the Bulldog Pro runs a 750W rear hub motor with 1350W peak output, tuned for high torque and sustained pulling power rather than just a quick burst.
What that means on the trail or road:
- Acceleration: Gets up to speed confidently, even loaded with gear or climbing out of the saddle.
- Hill performance: The motor, 26″ x 4.0″ tires, and stiff frame work together for steep, loose climbs where smaller city motors can struggle.
- Top speed: With pedal assist, the Bulldog Pro can help you reach up to about 28 mph in Class 3 configuration, while throttle-only riding typically tops out around 20 mph.
The assist system is built around a torque-focused sensor setup that looks at your pedal effort (and cadence) rather than just whether the cranks are moving. In practice, that usually feels:
- More natural and proportional to how hard you’re working
- Less “on/off” than a basic cadence-only system
- Better at matching power to terrain—light support on flats, more punch on climbs
If you’re upgrading from an entry-level cadence-sensor bike, the Bulldog Pro’s motor and assist feel more like an amplified version of your own legs than a simple on/off boost.
Battery, Range & Realistic Expectations
The Bulldog Pro’s dual-battery system is its headline feature:
- Two 48V 15Ah packs
- Combined 48V 30Ah (≈1440Wh total capacity)
Puckipuppy quotes a claimed 80–130 miles of range depending on assist level, terrain, rider weight, and pace. That’s optimistic—as all brand numbers are—but it does reflect a genuinely large battery system.
For planning, it’s more helpful to think in real-world bands:
- Everyday mixed riding:
Expect roughly 50–80 miles on a charge if you’re using PAS 3–5, seeing some hills, and mixing in a bit of throttle. - Range-focused riding:
With mostly lower PAS (2–3), steady pacing, and reasonable conditions, 80–100+ miles is realistic for many riders.
The key point: this is not a “maybe 40 miles if you baby it” battery setup. Even when you discount ideal test conditions, the Bulldog Pro sits in true long-range territory, with enough capacity for all-day adventures or several shorter rides between charges.
Brakes, Safety & Control
A dual-battery, full-suspension fat bike that weighs over 90 lb and can hit Class 3 speeds needs serious brakes—and the Bulldog Pro delivers.
Brakes
- Hydraulic disc brakes front and rear
- 180 mm rotors for strong leverage and improved heat management
Versus mechanical discs, hydraulics bring:
- Lighter lever feel and less hand fatigue
- Better modulation, especially on loose surfaces
- More consistent performance as pads wear
Combined with the fat tires and suspension, this brake setup is built to:
- Handle steep downhill runs with confidence
- Stay composed when you’re loaded with gear or riding in wet/loose conditions
Control & Security
- 2.8″ HD color display with speed, assist level, battery status, and ride data
- Display is removable and acts as an electronic key—no display, no power
- Thumb throttle for instant power when you need help getting up to speed or clearing obstacles
If you’re parking in public spaces regularly, the removable display/key is a small but meaningful security layer on top of a good lock.
Ride Feel, Handling & Terrain
The Bulldog Pro’s ride is defined by three elements:
- 26″ x 4.0″ fat tires
- Full suspension (110 mm front fork + rear shock)
- Long, stable chassis with a 400 lb payload rating
How It Feels
- Stable and planted: The wheelbase, fat tires, and overall weight make the bike feel very grounded—exactly what you want on gravel, fire roads, and loose surfaces.
- Comfortable over rough terrain: Suspension and tire volume work together to tame washboard, roots, potholes, and curb hits.
- Confident at Class 3 speeds: The overall package favors stability and control over razor-sharp flickability.
Where It Shines
- Gravel roads and forest service roads
- Light to moderate off-road trails
- Rough, broken pavement and back roads
- Sand, mud, and light snow (with tire pressure adjusted appropriately)
If your riding is 90% smooth city pavement, the Bulldog Pro will feel like overbuilt comfort. If your routes mix pavement, dirt, and rougher surfaces, the platform starts to feel purpose-built rather than excessive.
Comfort, Fit & Ergonomics
Even though the Bulldog Pro is built to be tough, it keeps rider comfort front and center.
Comfort highlights:
- Full suspension to reduce fatigue over long, uneven rides
- 26″ x 4.0″ tires run at moderate pressures for extra cush
- Upright-to-slightly-forward riding position that balances control with relaxed shoulders
- Comfort-oriented saddle suitable for longer outings
Fit notes:
- Recommended rider height: 5’4″–6’6″
- Standover height: about 32.9″
- Saddle height range: about 36.4″–39.8″ from the ground
If you’re near the lower end of that height range and prefer to flat-foot at stops, check those numbers against your inseam. For most average-to-taller riders, the single frame size should be workable with cockpit tweaks (bar angle, stem, seat position).
This is not a bike you buy for how it lifts—at ~92.5 lb, comfort is all about how it rides.
Utility & Everyday Use
The Bulldog Pro is more than a weekend toy; it can easily be treated as a small utility vehicle.
Where it shines in day-to-day life:
- Commuting and errands: Dual batteries and Class 3 assist make back-to-back trips easy—commute, grocery run, and extra stops on a single charge.
- Hunting and property work: The 400 lb payload, fat tires, and torque-forward motor suit carrying gear over grass, dirt, and rough access roads.
- Weekend adventures and bikepacking-style trips: Realistic 50–100 mile range means you can explore far from home without obsessing over the battery gauge.
- Security & storage: The removable display/key and stout frame design pair well with a heavy-duty lock for in-town parking.
If you think of your ebike as a car or ATV replacement for many local trips, the Bulldog Pro’s mix of range, comfort, and payload capacity makes a lot of sense.
Pros & Cons
Pros
- Serious long-range capability with dual 48V 15Ah batteries (48V 30Ah total, ≈1440Wh).
- Full-suspension fat-tire platform that feels stable and comfortable on gravel, dirt, snow, and rough pavement.
- 750W (1350W peak) rear hub motor with torque-focused assist for strong yet controlled power.
- Hydraulic disc brakes with 180 mm rotors matched to a heavy, fast bike.
- 400 lb payload rating, opening the door to heavier riders and real cargo loads.
- Removable color display that doubles as an electronic key for added security.
- One-size geometry that fits a wide height range (5’4″–6’6″), which helps for sharing and resale.
Cons
- Weight: Around 92.5 lb—this is not a bike you want to haul upstairs daily.
- Overbuilt for short, smooth city hops: If your rides are mostly flat, paved, and under 10 miles, a lighter commuter may be more convenient.
- Single frame size: Riders significantly below 5’4″ may find standover and saddle height intimidating.
- Less nimble in tight spaces: Fat tires and a long wheelbase trade flickability for stability.
- Dual batteries mean more to manage: Extra weight, higher up-front cost, and two packs to maintain and charge.
Who the Puckipuppy Bulldog Pro Is Best For
The Bulldog Pro is a great match if:
- You want true long-range capability and dislike thinking about mid-ride charging.
- You regularly ride mixed terrain: pavement, gravel roads, doubletrack, light singletrack, or snowy back roads.
- You’re a heavier rider or you carry real gear and appreciate a 400 lb payload rating.
- You like the idea of a full-suspension fat-tire ebike that still feels responsive thanks to torque-based assist and a high-peak motor.
- You see your ebike as a car or ATV alternative for local trips, not just a weekend toy.
Who Might Want a Different Bike
You might be happier with another model if:
- You live in a walk-up apartment or need to lift the bike often—92+ lb is a lot to muscle around.
- You ride almost exclusively on smooth city streets and want something lighter, narrower, and more agile.
- You’re significantly shorter than 5’4″ or very sensitive to higher standover heights.
- You prefer the feel and efficiency of a lighter commuter, gravel ebike, or mid-drive city bike.
- You don’t need dual batteries and would rather save weight and money with a single-pack setup.
Final Thoughts: Is the Puckipuppy Bulldog Pro Worth It?
The Puckipuppy Bulldog Pro isn’t trying to be a slim, minimalist city bike. It’s unapologetically a long-range, full-suspension, fat-tire workhorse aimed at riders who want big range, big comfort, and big capability in one package.
You’re getting:
- Dual 48V 15Ah batteries for legit all-day range
- A 750W / 1350W peak rear hub motor with torque-based assist for powerful yet controlled performance
- Full suspension and 26″ x 4.0″ tires that tame rough surfaces and build confidence off-pavement
- A 400 lb payload rating that supports real-world gear, cargo, and larger riders
If your riding involves long distances, mixed terrain, and real utility use, the Bulldog Pro belongs on your short list.
If you love the idea of an ebike but mostly ride short, smooth city trips and prefer something lighter and more nimble, you’ll likely be better served by a single-battery city commuter or compact folding ebike instead.
