VELOPRO BUYING GUIDE · 6 MIN READ
A dual battery fat tyre e-bike makes sense when you want substantial battery capacity, a comfortable ride over uneven surfaces and fewer interruptions to your riding routine. The VELOPRO M9 combines two removable batteries with 20 × 4-inch tyres and front and rear suspension. The key question is whether those features suit your routes, storage space and charging habits.
This guide explains what to look for in a dual battery electric bike, using the M9's published specifications to connect the numbers with everyday decisions.
Who is a dual battery fat tyre e-bike for?
Start with your week. Perhaps you commute across town, make a few extra stops and want enough battery capacity left for a weekend outing. Or your route includes patched tarmac and uneven paths, making ride comfort as important as the motor specification.
The M9 is worth considering if you can store it at ground level, appreciate its retro styling and want removable batteries for charging away from the bike. It deserves a more careful comparison if you need to carry a bicycle upstairs, lift it frequently or fit it into a small shared hallway.

What do the M9's two batteries actually give you?
The M9 has two removable 48V 17.5Ah batteries. Together, they provide a stated total capacity of 1,680Wh. Watt-hours are the most useful starting point when comparing stored energy across different e-bikes.
The calculation is straightforward: volts × amp-hours = watt-hours. For each M9 battery, 48 × 17.5 = 840Wh. Two batteries total 1,680Wh.
Think of watt-hours as the size of the energy supply, rather than a promised travel distance. Hills, headwinds, temperature, rider and luggage weight, tyre pressure and assistance level all influence how quickly you use it. Two batteries do not guarantee twice the real-world range of another bike.
For a useful comparison, consider your longest regular return journey, the help you typically want from the motor and whether charging is available at your destination. Keep a reserve for detours and changing conditions. Learn your bike's consumption on familiar routes before planning a longer ride around a published maximum.
Fat tyres or narrower tyres: which suits your route?
The M9 uses Kenda 20 × 4-inch fat tyres. Their broad profile is part of its distinctive appearance, but tyre choice should also reflect how and where you ride.
| What matters to you | Fat tyres | Narrower city tyres |
|---|---|---|
| Uneven surfaces | Can add cushioning when correctly inflated | Comfort depends more on tyre volume, setup and suspension |
| Smooth daily routes | Rolling feel depends on tread, pressure and the complete bike | Compare tread, pressure and total bicycle weight for your route |
| Storage and handling | Check clearance in racks, doorways and transport equipment | May be easier to accommodate in narrow spaces |
| Ownership | Check availability of the correct wide tyres and tubes | Check the exact size too; compatibility still matters |
If your route is almost entirely smooth cycle paths and you prioritise easy lifting, compare overall bicycle weight before choosing by appearance. If rough surfaces and comfort feature regularly in your week, the M9's combination is worth a closer look.
Fat tyres still need appropriate pressure and careful riding. They do not remove the risk of sliding on wet markings, loose surfaces or ice. Follow the tyre and bicycle instructions for your setup.
What else matters beyond battery size?
A good buying decision connects the whole specification with your routine.
- 250W rear-hub motor and 60Nm stated torque: consider your starts, inclines and preferred effort, rather than comparing wattage alone.
- Five pedal-assist levels: adjust support as your route changes. Higher assistance generally uses more energy.
- Shimano seven-speed drivetrain: mechanical gears help you choose a comfortable pedalling rhythm alongside the motor's assistance.
- Front and rear suspension: useful features to assess for uneven roads; correct setup and maintenance still matter.
- Hydraulic disc brakes with 180mm rotors: check braking setup and include brake inspection in your maintenance routine.
The stated maximum assisted speed is 25km/h. Before buying, check the supplied configuration and the rules where you intend to ride, including access rules for paths. A motor rating alone does not establish permission for every location or use.
Picture a city week and a weekend ride
For weekday commuting, the useful combination is removable batteries, selectable assistance and practical equipment such as lights and fenders. Charge according to the instructions, check the bicycle before leaving and choose assistance that matches the route. A comfortable pace can make regular cycling easier to fit into the day.
At the weekend, a route with uneven sections gives you a reason to consider the suspension and wider tyres. Plan around suitable roads and permitted paths, with stopping points and an energy reserve. Suspension does not make every trail suitable for the bike or rider.

Plan storage, fit and charging before ordering
The technical specifications list the M9's net weight as 49.5kg. That makes access a real buying criterion. Measure your doorway and storage area, check any lift or transport limits and think through the route from the street to its parking spot.
VELOPRO recommends a rider height of 160–200cm, but height alone cannot confirm a comfortable fit. Compare the published dimensions with your inseam and reach, and consider how confidently you can mount, stop and manoeuvre the bike.
Plan charging time for both packs and confirm the supported charging procedure; do not assume one charger charges both simultaneously. Use the supplied compatible equipment and follow the battery instructions, away from excessive heat and intense sunlight.

Frequently asked questions
Does a dual battery e-bike always travel twice as far?
No. More stored energy can support longer riding between charges, but actual distance depends on the whole bike, route, conditions and rider. Compare watt-hours and leave a practical reserve.
Can the VELOPRO M9 batteries be removed?
Yes. The M9 has two removable 48V 17.5Ah batteries. Follow the supplied instructions for removal, charging and refitting.
Is the M9 suitable for carrying upstairs every day?
Its listed 49.5kg net weight makes frequent lifting an important consideration. Check your access and handling needs before choosing it for an upstairs home.
Is a fat tyre e-bike a good commuting choice?
It can be, especially when comfort on uneven surfaces matters and you have suitable storage. Compare weight, fit, tyres, charging and your actual route before deciding.
Choose around the riding you actually do
The M9's appeal is the combination of substantial removable battery capacity, fat tyres, suspension and retro styling. If those features answer your daily needs—and you have suitable access and storage—it belongs on your shortlist.
