FREESKY Alaska Dual Battery FAQ: How the System Works, Range Explained & Battery Questions Answered
One of the most common questions about the FREESKY Alaska series is not about speed or motor power—it’s about how the dual-battery system actually works in real-world use.
Can the bike run on just one battery? What happens if one battery fails? Why do some units use 18Ah + 23Ah while others use 18Ah + 27Ah? And how far can you really ride on a single charge?
This guide explains the Alaska dual-battery system in a simple, practical way so riders can understand how the system behaves before and after purchase.
Understanding the Alaska Dual-Battery System
The Alaska series uses a dual-battery architecture to extend riding range and improve flexibility.
Depending on production batch and configuration, the system may include:
Battery Configurations
Configuration
Structure
Total Capacity
Standard System
18Ah + 23Ah
41Ah
Upgraded System
18Ah + 27Ah
45Ah
Both systems follow the same working principle: two independent batteries working within one eBike system.
👉 You can view the latest configuration on the Alaska product page.
How Does the Dual-Battery System Work?
The Alaska dual-battery system is designed to manage power automatically.
In normal riding conditions:
- The system draws power from the batteries in a controlled way- No manual switching is required- Riders do not need to operate batteries separately- The system ensures stable output during riding
Key point:
👉 The dual-battery system is designed for extended range, not increased speed
Do Both Batteries Need to Be Installed or Working?
No.
The bike can operate with only one working battery.
If one battery is removed, damaged, or not functioning:
- The remaining battery can still power the bike- Pedal assist and throttle functions remain available- The bike can still be used normally
If One Battery Fails, Can I Still Ride?
Yes.
As long as one battery is functional, the bike can continue operating.
Common situations include:
- One battery stops charging- One battery is removed for servicing- One battery reaches end of lifespan
In all cases, the remaining battery can still power the system.
Do I Need to Replace Both Batteries If One Fails?
No.
Each battery in the Alaska system is independent.
If one battery fails:
- You only need to replace the defective one- The other battery can continue being used normally
This reduces maintenance cost and avoids unnecessary replacement.
How Far Can You Ride with One Battery vs Two Batteries?
Range depends on configuration, riding mode, and conditions.
Standard System (18Ah + 23Ah)
Setup
Estimated Range*
18Ah Battery Only
45–80+ miles
23Ah Battery Only
60–100+ miles
Dual Battery
Up to 160 miles
Upgraded System (18Ah + 27Ah)
Setup
Estimated Range*
18Ah Battery Only
45–80+ miles
27Ah Battery Only
70–120+ miles
Dual Battery
120–200+ miles
*Actual range varies based on rider weight, terrain, wind, temperature, tire pressure, and assist level.
👉 Full product details: Alaska Pro product page.
Why Do Two Alaska Systems Have Different Battery Capacities?
The difference between 41Ah and 45Ah systems comes from:
- Different production batches- Continuous product optimization- Improved lower-frame battery capacity
However, both systems share the same core design philosophy:
- Dual independent batteries- Same riding behavior- Same operational logic
The difference mainly affects total range potential, not usability.
Is the Advertised 120–200+ Mile Range Real?
Yes, but only under optimized riding conditions.
Maximum range is typically achieved with:
- Low pedal assist levels (PAS 1–2)- Flat or mild terrain- Moderate riding speed- Proper tire pressure- Efficient riding style
Real-world range will vary based on usage habits.
Does Throttle-Only Riding Reduce Range?
Yes, significantly.
There are two main riding modes:
Pedal Assist (PAS): rider + motor share workloadThrottle Only: motor provides full power
Range impact:
Mode
Range Impact
Low PAS
Maximum efficiency
Medium PAS
Balanced performance
High PAS
Reduced range
Throttle Only
Shortest range
If maximum mileage is the goal, pedal assist is recommended.
Does One Battery Affect Speed or Power?
No.
Top speed and motor output are controlled by the motor and controller system.
Battery configuration mainly affects:
- Riding range- Charging frequency
Not performance or speed.
Do I Need to Charge Both Batteries Together?
No.
You can:
- Charge both batteries at the same time- Charge individually- Charge only one battery if needed
For long-term balance, keeping both batteries at similar charge levels is recommended.
Why Use a Dual-Battery System Instead of One Large Battery?
The dual-battery system offers:
- Better weight distribution- Easier battery replacement- Increased flexibility- Higher total energy capacity- Redundancy (one battery can still run the bike)
This makes the system more practical for long-distance riding.
Final Thoughts
The FREESKY Alaska dual-battery system is designed to balance long-range capability with real-world usability.
Key takeaways:
- Alaska uses either 18Ah + 23Ah (41Ah) or 18Ah + 27Ah (45Ah) configurations- The bike can operate with only one battery- You do not need to replace both batteries if one fails- Dual batteries primarily increase range, not speed- Throttle-only riding results in shorter range than PAS riding- The system is designed for flexibility, redundancy, and long-distance riding

5 Reasons an eBike Is the Perfect Father’s Day Gift
Every Father's Day, the same gift ideas seem to make the rounds: smartwatches, headphones, grilling tools, tablets, or another gadget that feels exciting for a few weeks before ending up forgotten in a drawer.
But if you want to give Dad something he'll actually use long after Father's Day is over, a fat tire electric bike can offer something most gadgets simply can't: real experiences.
An eBike isn't just another gift to unbox. It creates opportunities for adventure, exploration, and quality time outdoors. It can turn ordinary errands into enjoyable rides, make weekend outings more exciting, and help Dad spend more time doing something he genuinely enjoys.
Here are five reasons an eBike may be the best Father's Day gift this year.
1. An eBike Creates Memories, Not More Screen Time
Most gadgets encourage us to spend more time looking at screens.
An eBike does the opposite.
Instead of scrolling through apps or sitting indoors, Dad can head outside to explore local trails, ride through the neighborhood, visit a favorite coffee shop, or enjoy a sunset ride after work.
Some of the best memories aren't made in front of a screen. They're created while discovering a new route, riding with family, or spending a quiet morning outdoors.
The best gifts aren't always the most high-tech. They're the ones that create stories worth telling.
2. It's Something He'll Actually Use
Let's be honest: many Father's Day gadgets lose their appeal surprisingly quickly.
An eBike is different because it naturally fits into everyday life.
Many riders discover that a long-range electric bike becomes something they use several times a week rather than a gift that collects dust.
Dad can use it to:
- Commute to work- Run errands around town- Ride with family and friends- Explore local bike paths- Stay active outdoors- Replace short car trips- Enjoy weekend adventures
The pedal-assist system makes riding easier and more enjoyable, even for people who haven't ridden a bike in years.
That means it's not just a gift—it's something that becomes part of a daily routine.
3. eBikes Make Riding Fun Again
One of the biggest reasons people fall in love with eBikes is simple: they make riding enjoyable.
Hills feel less intimidating. Longer rides become more achievable. Headwinds become manageable. Riders can travel farther without feeling exhausted when they arrive.
For many dads who used to ride more often—or have talked about getting back into cycling—an eBike removes many of the obstacles that make traditional cycling feel challenging.
The result is often more confidence, more exploration, and more time spent outdoors.
For dads who love adventure, models like the FREESKY Swift Horse Ultra electric bike are built to make every ride more exciting. With a powerful BAFANG motor, full suspension, and up to 140 miles of range, it gives riders the freedom to explore farther without worrying about battery life or challenging terrain.
Whether it's a weekend trail ride, a beach trip, or discovering new backroads, the Swift Horse Ultra helps turn ordinary rides into memorable experiences.
4. It Encourages a More Active Lifestyle
Unlike many gifts that encourage sitting still, an eBike encourages movement.
One of the biggest misconceptions about eBikes is that riders aren't exercising. In reality, riders still pedal and stay active while enjoying assistance when they need it.
Dad can choose how much effort he wants to put into every ride.
Want a workout? Use a lower assist level.
Want a relaxing cruise? Let the motor do more of the work.
This flexibility makes riding more accessible and enjoyable, which often leads to greater consistency.
Fresh air, sunshine, movement, and less time behind a screen? That's a combination many dads appreciate.
5. It's a Gift That Keeps Delivering All Summer Long
Most Father's Day gifts come with a brief "wow" moment.
An eBike keeps providing value every time Dad rides.
A reliable commuter electric bike can make everything from everyday errands to weekend adventures more enjoyable throughout the summer.
Summer is the perfect season for:
- Weekend rides- Family outings- Campground cruising- Exploring local trails- Beach trips- Visiting nearby towns- Evening rides around the neighborhood
Instead of being forgotten after a few weeks, an eBike becomes part of the entire season—and often many years beyond.
And once Dad starts riding, don't be surprised if the rest of the family wants one too.
Give Dad Something Better Than Another Gadget
This Father's Day, skip the predictable tech gifts and choose something that brings freedom, adventure, and enjoyment into everyday life.
An eBike isn't just a product. It's a reason to get outside, explore more, and create lasting memories.
And unlike many gifts that lose their appeal over time, the benefits of riding continue long after Father's Day has passed.
Find the Right Father's Day eBike
Whether Dad enjoys weekend adventures, daily rides around town, or discovering new places with family, choosing the right eBike can make this Father's Day one he'll never forget.
Explore our collection of electric bikes for adults and find a gift that keeps delivering long after Father's Day is over.

How Far Can an Electric Bike Go? Tips for Planning Longer Summer Rides in the UK
Summer is one of the best times to enjoy an electric bike in the UK. Whether you're riding through countryside lanes, commuting into town, exploring coastal paths, or planning a weekend adventure, one question always comes up:
How far can an electric bike actually go on a single charge?
The answer depends on several factors, including battery size, terrain, riding style, and weather conditions. But thanks to modern battery technology, many riders are surprised by just how far today’s e-bikes can travel.
In this guide, we’ll explain what affects e-bike range, how to maximise battery performance, and how to plan enjoyable longer-distance summer rides across the UK.
What Is E-Bike Range?
E-bike range refers to the distance an electric bike can travel on a fully charged battery.
Some riders only need enough range for short daily commutes, while others want an e-bike capable of long countryside rides or all-day touring.
Depending on the model and riding conditions, most electric bikes can typically cover:
- 20–40 miles (32–64 km) on smaller battery systems
- 50–80 miles (80–129 km) on larger batteries
- 100+ miles (160+ km) on high-capacity or dual-battery e-bikes
For riders interested in touring, commuting, or weekend exploration, long range electric bikes have become increasingly popular across the UK.
What Affects E-Bike Range?
No two rides use battery power in exactly the same way. Here are the main factors that influence how far your e-bike can go.
1. Pedal Assist Level
Higher pedal assist settings provide more support from the motor, but they also use more battery power.
Using lower assistance levels can significantly extend your range, especially on flatter cycle routes or canal paths.
For longer journeys, many riders alternate between low and medium assist levels to balance comfort and efficiency.
2. Terrain and Hills
Terrain plays a major role in battery consumption.
Flat roads and paved cycleways require far less power than:
- Steep hills
- Gravel tracks
- Forest trails
- Rural climbs
This is especially important in hilly areas such as the Lake District, Yorkshire Dales, Wales, or the Scottish Highlands.
That’s why powerful electric mountain bikes and fat tyre e-bikes are popular among riders tackling mixed terrain.
3. Rider and Cargo Weight
Additional weight increases motor workload and battery usage.
This includes:
- Backpacks
- Shopping bags
- Child seats
- Touring equipment
- Camping gear
If you regularly carry extra cargo, choosing a higher-capacity battery system can help maintain consistent range.
4. Wind and Weather Conditions
British weather can impact e-bike performance more than many riders expect.
Strong headwinds require the motor to work harder, while colder temperatures can temporarily reduce lithium battery efficiency.
Fortunately, warmer summer conditions are generally ideal for achieving maximum range.
5. Tyre Pressure and Bike Maintenance
Simple maintenance can noticeably improve efficiency.
To maximise your e-bike range:
- Keep tyres properly inflated
- Lubricate the chain regularly
- Check brake alignment
- Keep the drivetrain clean
This is especially important on full suspension e-bikes and larger fat tyre electric bikes, which naturally create more rolling resistance.
How to Plan Longer Summer E-Bike Rides
One of the biggest advantages of an e-bike is the ability to explore farther with less fatigue.
Here are a few ways to make the most of your summer rides in the UK.
Choose Scenic Routes
The UK offers plenty of excellent cycling destinations, including:
- Coastal paths
- National parks
- Forest trails
- Canal towpaths
- Countryside villages
- Seaside promenades
A capable all-terrain electric bike makes it easier to handle changing surfaces throughout longer rides.
Understand Your Battery Capacity
Before setting off, it helps to know:
- Your battery size
- Estimated riding range
- Charging time
- Remaining battery percentage
For example:
- The FREESKY Warrior Pro features a 48V 30Ah Samsung battery with up to 120 miles (193 km) of range.
- The Alaska Pro dual battery system can deliver up to 200+ miles (320+ km) per charge for long-distance touring and adventure riding.
For riders prioritising distance, dual battery electric bikes are becoming increasingly popular.
Use Assist Modes Wisely
You don’t always need maximum power.
Using:
- Eco mode on flatter roads
- Medium assist for general riding
- Higher assist only on climbs
can help extend battery life significantly during longer journeys.
Bring Your Charger for Day Trips
If you’re planning:
- A café stop
- A pub lunch
- Camping
- A visit with friends
- An overnight stay
bringing your charger can provide extra peace of mind and extend your riding distance.
Summer Ride Ideas by Distance
Need inspiration for your next ride? Here are a few ideas based on distance.
5–10 Miles (8–16 km)
- Local village rides
- Seafront cruising
- Quick errands
- Evening countryside rides
10–25 Miles (16–40 km)
- Canal path rides
- National cycle routes
- Park-to-park journeys
- Market town exploration
25+ Miles (40+ km)
- Full-day countryside adventures
- Coastal touring
- Forest trail exploration

Tips to Maximise E-Bike Range
Want to get the most from every charge? Try these simple habits:
- Fully charge before longer rides
- Keep tyres inflated correctly
- Pedal consistently alongside assist
- Avoid aggressive acceleration
- Ride at a steady pace
- Store your battery indoors when possible
- Reduce unnecessary cargo weight
Small adjustments can make a noticeable difference over longer distances.
