The M5 is a mid-range electric bike designed for commuting and casual riding on paved surfaces

The M5 electric bike is a pedal-information model made by Stromer, a Swiss manufacturer. It has a 45-kilometer range (about 28 miles) on a single charge, a top speed of 45 kilometers per hour (28 mph) when pedal-information is engaged, and weighs roughly 29 kilograms (64 pounds). The motor is a hub drive, meaning the power comes from the wheel itself rather than the pedals, which makes it simpler to maintain than mid-drive systems.

The bike is built for urban commuting and short recreational trips rather than off-road or mountain terrain. It comes with integrated lights, a display screen on the handlebars, and a frame-mounted battery that you remove to charge indoors. The price typically ranges from $3,000 to $4,000 depending on the retailer and any current promotions, though this varies by region and seller.

Key Takeaways

  • The M5 uses a hub-drive motor and removable battery, making it straightforward to charge at home or in an office without moving the entire bike.
  • A single charge covers roughly 28 miles under normal conditions, which is sufficient for most daily commutes but not for long weekend trips.
  • The bike reaches 28 mph with pedal-information active, so you will need to check your local regulations about speed limits for electric bikes in your area.
  • At 64 pounds, the M5 is heavier than a standard bicycle but lighter than many full-suspension electric bikes, making it manageable to carry up stairs or load into a vehicle if needed.
  • Stromer bikes are sold through authorized dealers rather than big-box retailers, so availability depends on whether a dealer operates in your region.

Motor and Power System

The M5 uses a direct-drive hub motor housed in the rear wheel. This design means the motor is sealed and protected from dirt and water, requiring less maintenance than exposed chain-drive systems. The motor draws power from a 529-watt-hour lithium battery mounted low on the frame, which keeps the bike's center of gravity stable and makes it easier to handle at a stop.

The battery charges fully in about 3.5 to 4 hours using a standard wall outlet. You remove it from the frame using a key, so you can charge it indoors without bringing the entire bike inside — useful if you live in an apartment or have limited storage. The display screen shows your current speed, remaining battery, and distance traveled, and you control the level of motor information through buttons on the handlebars.

The motor provides pedal-information only, meaning it does not propel the bike on its own if you stop pedaling. You must be actively pedaling for the motor to engage. This design keeps the bike legal in most jurisdictions where electric bikes are classified by power output and speed, though you should verify your local rules before purchase.

Range, Speed, and Real-World Performance

Stromer rates the M5 at 45 kilometers (28 miles) per charge under ideal conditions. Real-world range depends on terrain, rider weight, weather, and how much you use the motor. Flat urban commuting with moderate pedal-information will get you closer to the rated distance. Hilly terrain, heavier riders, or maximum motor information will reduce range by 20 to 40 percent.

The bike reaches 45 kilometers per hour (28 mph) with pedal-information active. Many U.S. states and European countries classify electric bikes into categories based on speed and power, and the M5 may fall into a category that requires registration or restricts where you can ride. Before purchasing, check whether your city or state has specific rules about electric bike speed limits and where they are permitted on bike paths and roads.

The bike accelerates smoothly from a stop because the motor engages gradually as you pedal harder. There is no sudden jolt or lag. Braking is handled by hydraulic disc brakes, which provide reliable stopping power even in wet conditions and require less hand strength than rim brakes.

Weight, Handling, and Storage

At 29 kilograms (64 pounds), the M5 is significantly heavier than a standard road or hybrid bike but lighter than many full-suspension mountain bikes or cargo electric bikes. The weight is distributed low and centered on the frame, so the bike does not feel top-heavy when you are riding. However, if you need to carry it up stairs, load it into a car, or store it in a small space, you will notice the weight.

The frame is aluminum, which resists rust and keeps the overall weight down. The bike has a step-through option available, which makes mounting easier if you have limited mobility or wear a skirt or dress. The removable battery is the heaviest single component at about 3 kilograms (7 pounds), so removing it before moving the bike reduces the load you are handling.

Storage is straightforward because the battery comes off. If you live in an apartment or office without find bike parking, you can remove the battery and bring it inside, leaving the bike locked outside. The frame itself is less attractive to thieves without the battery, though you should still use a sturdy U-lock.

Maintenance and Durability

The hub-drive motor has no chain or gears to maintain, which simplifies upkeep compared to mid-drive systems. You will still need to maintain the brakes, tires, and drivetrain like any bike, but the motor itself requires no regular service. Stromer provides a two-year warranty on the frame and motor, and the battery typically retains 80 percent of its capacity after three years of normal use.

Tire replacement and brake adjustment are standard bicycle maintenance that any local bike shop can perform. However, if the motor or battery fails, you will need to contact an authorized Stromer dealer, as the components are proprietary. This means repair costs may be higher than for bikes with standard parts, and you may face longer wait times if your local dealer has a backlog.

The bike is water-resistant but not waterproof. You can ride in light rain without damage, but you should avoid submerging it or riding through deep water. The sealed hub motor and battery connectors are designed to shed water, but prolonged exposure to moisture can eventually cause problems.

Where to Buy and Pricing

Stromer bikes are sold exclusively through authorized dealers, not through Amazon, Walmart, or other online marketplaces. To find a dealer near you, visit the Stromer website and use their dealer locator tool. Availability varies by region — some areas have multiple dealers, while others may have none within a reasonable distance.

Pricing for the M5 typically falls between $3,000 and $4,000, though this varies by dealer and region. Some dealers offer financing options or seasonal discounts. You may also find used M5 bikes on classified sites or through local bike shops, which can cost $1,500 to $2,500 depending on age and condition. When buying used, ask for maintenance records and have the battery tested to confirm it still holds a charge.

Many regions offer tax credits or rebates for electric bike purchases. Check with your local government or environmental agency to see whether you are in an area with such programs. Some employers also offer commuter benefits that can be applied toward electric bike purchases.

Alternatives to Consider

If the M5 does not fit your needs, several other mid-range electric bikes are worth comparing. The Trek Verve+ is lighter and less expensive but has a shorter range. The Riese & Müller Load is heavier and more expensive but designed for cargo and longer trips. The Giant Quick-E is faster and more powerful but costs more and is harder to find in some areas.

If you need longer range, consider a bike with a larger battery — many models offer 600 to 750 watt-hours, which extends range to 40 to 50 miles. If you need to carry cargo or passengers, look for cargo-specific electric bikes. If you plan to ride off-road or on rough terrain, a full-suspension electric mountain bike will be more durable, though it will cost more and be heavier.

Frequently Asked Questions

Can I ride an M5 without using the motor?

Yes. The M5 is a full bicycle with pedals and gears, so you can ride it like a regular bike if the battery is dead or if you choose not to use the motor. However, at 64 pounds, it will feel noticeably heavier than a standard bike when you are pedaling without information.

How long does the battery last before it needs replacement?

Lithium batteries typically retain 80 percent of their capacity after 500 to 1,000 charge cycles, which is roughly three to five years of regular use. Replacement batteries cost $800 to $1,200. Proper storage and avoiding extreme temperatures extend battery life.

Is the M5 legal to ride on bike paths in my area?

It depends on your local regulations. Many places allow electric bikes up to 28 mph on bike paths, while others restrict them to 20 mph or ban them entirely. Check your city or state's electric bike classification rules before purchasing. Some areas require registration or a license plate for bikes above a certain speed.

What happens if the motor fails after the warranty expires?

Motor repairs are handled by authorized Stromer dealers and typically cost $500 to $1,500 depending on the problem. If the motor is beyond repair, replacement costs $1,500 to $2,000. This is why checking warranty coverage and dealer proximity before purchase is important.

Can I upgrade the battery to get longer range?

Stromer does not currently offer a larger battery option for the M5. The 529-watt-hour battery is the standard for this model. If you need significantly longer range, you would need to consider a different Stromer model or a different brand entirely.
