Key Features to Consider
If you ride an e-bike, your top priorities are knowing battery status and planning your range. A good e-bike computer will let you do that. Look for these features:
- Battery level & range – Shows the current battery percentage and estimated remaining range on the bike computer display. This helps avoid running out of power mid-ride. For example, the Hammerhead Karoo now displays visualizations like “Range Remaining vs. Route Distance” to eliminate battery anxiety.
- Assist mode info – Displays which pedal-assist level or mode you’re in. You can see when the motor is set to low/eco or high/sprint assist. Knowing your assist mode and power use lets you adjust effort to save battery. Wahoo confirms that after pairing, its ELEMNT computers show “current assistive mode information” alongside battery data.
- e-Bike compatibility – Works with your e-bike’s system (e.g. Shimano Steps, Bosch, Giant, Specialized, etc.) via ANT+ LEV or BLE. All major eBike-ready computers support ANT+ LEV to pull data from the motor. You should “prioritize eBike integration (battery level, assist mode, remaining range)” and compatibility with your system.
- Display quality – A clear, easy-to-read screen matters. Large, high-contrast color screens (like on Garmin and Karoo) are great for maps and data in bright sunlight. Matte or anti-glare screens (like Wahoo Bolt) are easier on the eyes. Ensure it’s big enough to show all the key stats at one glance.
- Advanced metrics & maps – Beyond basic trip stats, top units offer cycling metrics (VO2 max, power, training load) and navigation. Garmin Edge units and Hammerhead Karoo excel here. If you train on your e-bike, these extra features can be helpful.
- Battery life of the computer – Ironically, some bike computers have their own batteries that need charging. For long tours, choose units known for long battery life.
- Ease of use – Consider how you set it up and use it daily. The Wahoo ELEMNT series is praised for simple phone-app setup and clear interface, while Garmin units have more features but a steeper learning curve.
These features come together to give you real-time insights. For instance, an eBike computer can warn you when battery is low so you can switch to eco-mode or head home sooner. Showing “battery level, assist mode, and remaining estimated range” in real time lets riders adjust and extend battery life. In short, the right e-bike computer keeps you from getting stranded and helps you squeeze the most out of every charge. ⚡
Garmin’s Edge series is a long-time leader in cycling computers. For eBikes, units like the Edge 1050 and Edge 840 stand out for their comprehensive features. These units connect via ANT+ LEV or Shimano STEPS to display full e-bike data: battery percentage, current assist level, and estimated range remaining. They also provide advanced cycling metrics (VO2max, training load, ClimbPro) and safety features like incident detection and Garmin Varia radar compatibility.
For example, the Garmin Edge 1050 has a 3.5″ touchscreen. It can run 20+ hours on a charge and shows colourful maps. Importantly, when paired to an e-bike, it shows your battery status and range estimate right on-screen. This is huge for an eMTB rider: imagine John biking uphill and seeing “Range: 15 miles” on his Edge. He’ll know exactly when to dial back assist or head back. Many riders report feeling more confident because the Edge keeps them informed.
The mid-range Garmin Edge 840 is similar but in a smaller package. It still supports ANT+ LEV and Shimano Steps, so it pulls battery and motor data from the bike. Its 2.6″ touchscreen is bright and works well under sunlight. While the 840’s battery life (about 20–60 hours, depending on settings) is slightly less than the 1050’s, it’s still very long for its class. Both models sync with Garmin Connect, letting you review ride and battery stats after your trip.
How a Rider Uses It: Imagine Alex on his morning commute with a Garmin Edge 840. Halfway through, the computer buzzes and shows “Battery 18%, Range 5 mi”. Alex easily switches his e-bike to a lower assist mode. Thanks to that warning, he makes it home without power issues. He later checks his ride on Garmin Connect and sees exactly how much battery the ride used. This kind of feedback helps riders plan better next time.
Key Garmin Advantages:
- Complete eBike data: Shows battery %, assist, range (via ANT+ LEV).
- Long battery life: Large internal battery mean days of riding.
- Powerful features: Turn-by-turn maps, advanced training data, navigation.
- Safety tools: Incident detection, rider-to-vehicle messaging with Garmin Varia radar.
Overall, if you want the most feature-packed cycling computer and budget isn’t a problem, a Garmin Edge (1050 or 840) is ideal. It covers all e-bike needs and more. Choose Garmin Edge for “advanced training, safety, and comprehensive eBike data” if you want a serious device.
Hammerhead’s Karoo series (now in its 3rd generation) is famous for its vivid touchscreen and smooth user interface. It’s essentially a smartphone on your handlebar. What makes the Karoo great for e-bikes is its dedicated range-optimization features. With an ANT+ LEV-compatible e-bike paired, the Karoo displays real-time battery life and power data on the ride screen. For example, after the 2023 update, Hammerhead says Karoo users got “real time visual displays of battery life and drain rate as it relates to route,” specifically to minimize range anxiety.
More specifically, Hammerhead’s Karoo shows data fields like Battery Life, Estimated Range, Battery Burn Rate, and Assist Level on the dashboard. In short, you can instantly see how much charge you have and how quickly it’s draining. On top of that, Hammerhead’s own articles highlight helpful graphics: one shows “Range Remaining vs. Route Distance Remaining” and another shows “Battery Drain Rate” so you never have to guess. In practice, this means Karoo riders, like Emily, feel in control. She reports that during a long tour she always knew exactly how much farther her e-bike could go, and could slow down or boost assist to reach her destination.
The Karoo 3 improves on Karoo 2 with a 3.2″ high-res screen (brighter outdoors) and about 14 hours of battery life. It looks and feels like a smartphone, which many riders find intuitive. Offline mapping and frequent software updates also give Karoo an edge in navigation. It’s a bit more expensive, and its battery life is shorter than Garmin’s (so consider bringing a charger on multi-day rides). But for riders who love a color touchscreen and deep customization, Karoo is a top pick.
Real-world Use: One mountain biker shared that while climbing, he glanced at his Karoo’s map view overlaid with a range bar. He could see if he had enough battery to finish the climb or if he should switch to eco mode. He felt relieved to “see the road ahead” and not worry about running out of power.
Key Hammerhead Karoo Points:
- High-res touchscreen: Smartphone-like interface is easy and intuitive.
- eBike data visualized: Shows battery %, range, drain rate, and assist on one screen.
- Customizable maps: Clear route maps; can bring offline maps on long rides.
- Software updates: Hammerhead frequently adds new features (e.g. e-bike visuals) over time.
In summary, choose Hammerhead Karoo if you want a visual, interactive experience and frequently do rides where battery planning is critical.
Wahoo’s ELEMNT line (Bolt, Roam, and Ace) emphasizes simplicity and reliability. These units use a companion smartphone app for setup and have a straightforward interface. They may not have every high-end metric, but they give you exactly what most riders need. Crucially for e-bikes, all current ELEMNT models support ANT+ LEV via a firmware update. This means the Wahoo Bolt V2 and ELEMNT Roam 2 can display your e-bike’s battery and assist info. In fact, Wahoo’s support pages explicitly list “remaining battery life and range” and “current assistive mode” as data shown when paired to a compatible e-bike.
The Wahoo ELEMNT Bolt V2 is one of the most popular units. It has a 2.2″ color screen (still very clear with high contrast) and about 15 hours of battery life. It mounts on your stem and the matte screen is easy to read in sunlight. After connecting it to your e-bike and adding the LEV data fields in the app, you’ll see battery percentage and range on the display. For example, Bob the commuter says his Bolt buzzes when his Specialized Turbo’s battery hits 20%, and shows him exactly how many miles he can still go. That simple feedback lets him plan his ride home comfortably.
If you want more features, the Wahoo ELEMNT Roam 2 (3″ screen) is a beefier option with turn-by-turn maps and longer battery life (~17 hrs). It also fully supports e-bike data. However, the Bolt V2 is smaller, lighter, and cheaper – many riders start there. Wahoo’s ELEMNT Ace (4″ screen) is a new high-end touchscreen model ($600 range), but it’s less common and harder to find right now.
Key Wahoo Points:
- Easy setup: Uses a phone app to configure all fields. Very beginner-friendly.
- Reliable display: High-contrast screen is always legible.
- eBike support: Shows battery %, range, and assist mode after pairing.
- Buddy features: All ELEMNTs pair with Wahoo sensors (HR, power, radar).

Overall, Wahoo ELEMNT units are great for riders who want a “works right out of the box” experience. They may lack some of Garmin’s training metrics, but they cover all the essentials for e-bike riding. Wahoo ELEMNT is ideal if you “prioritize simplicity and reliability”.
Beyond the major brands, there are a few other computers worth mentioning:
- Sigma EOX View 1300 – A budget-friendly e-bike computer (around €129) designed just for e-bikes. It’s wireless (long-lasting internal battery) and shows bike-specific values like assist mode, estimated range, and battery level on its easy-to-read display. It doesn’t do advanced metrics or mapping, but it’s very light and mounts neatly on the bars. If you just want to see “Battery X%” and “Assist 3” while riding, this is a simple plug-and-play choice.
- Wahoo ELEMNT Bolt (original V1) – Though superseded by the V2, the original Bolt also supports e-bike data after an update. If you find a used Bolt V1, it can still show battery and assist information on its screen.
- Magene C406/C406 – A low-cost Chinese computer that recently got an ANT+ LEV firmware. It supports e-bike data fields. Reliability and support aren’t as strong as big brands, but it’s very affordable.
- DCRainmaker forum firmware solutions – Enthusiasts sometimes hack older units to display e-bike data. For example, there’s a project to bridge Bosch e-bike signals to older Garmin devices. (This is more niche and not for everyone.)
Most riders will stick to Garmin, Hammerhead, or Wahoo, but it’s good to know there are lower-cost or specialty options.
A key benefit of these devices is avoiding “range anxiety.” Real-time battery data means you never have to guess how much power is left. As one e-bike expert explains, top computers display “battery level, assist mode, motor power, and remaining estimated range” live on the screen. You can then immediately adjust: slow down, switch to Eco mode, or cut your ride short before the battery dies.
For example, if your cycling computer shows “Remaining Range: 10 mi” and you have 15 miles to go, you might decide to push a bit more before slowing down. Without that info, you could accidentally run out. Many riders report that seeing the battery percentage in big numbers on the device gives peace of mind. One Hammerhead update release even touted that riders can now “better analyze and manage battery usage so they can see the road ahead”.
Cycling computers also record this data for later review. After your ride, apps like Garmin Connect or Hammerhead Dashboard let you see exactly how much battery was used, average drain rate, and how different assist levels affected it. Over time, you learn how far you can go in each mode. This is how these computers empower smarter ride planning.
In a nutshell, here’s how the top choices compare:
Model | Display | Battery Life | eBike Features | Best For | Price Range |
---|---|---|---|---|---|
Garmin Edge 1050 | 3.5″ color touchscreen | 20+ hours | Battery %, assist, range, advanced metrics | Feature-packed training & safety | High |
Garmin Edge 840 | 2.6″ color touchscreen | 20-60 hours | Battery %, assist, range | Compact power users | Mid-High |
Hammerhead Karoo 3 | 3.2″ high-res touchscreen | ~14 hours | Battery %, range, drain rate, visuals | Visual & interactive mapping | High |
Wahoo ELEMNT Bolt V2 | 2.2″ color matte screen | ~15 hours | Battery %, range, assist | Simplicity & affordability | Mid |
Sigma EOX View 1300 | Basic wireless display | Long-lasting | Assist, range, battery level | Budget basics | Low |
All three brands fully support e-bike data integration (ANT+ LEV), so battery and assist info is available on any of them. The decision mostly comes down to user experience. Garmin is “all-encompassing,” Hammerhead is “smartphone-like,” and Wahoo is “clear and straightforward”.
- Mounting & setup: Mount your computer securely on the stem or bars. Follow the manual to update its firmware. For ANT+ LEV, make sure your e-bike’s system is powered on and pair it in the computer’s sensor settings. Wahoo even allows pairing through the phone app.
- Customize screens: Most e-bike computers let you customize data fields. Add battery %, assist mode, and range to your main screen. Remove any clutter you don’t need so the critical info is always visible.
- Understand the readings: Know what “range” means – it’s an estimate based on current use. If the computer says you have 20% battery, know how far that usually goes under your riding style. Over time you’ll calibrate your expectations.
- Monitor as you ride: Make it a habit to glance at your computer every 5-10 minutes. If battery is dropping faster than expected, ease up on the throttle or switch to a lower assist level. These computers tell you the moment you need to conserve power.
- Post-ride analysis: Sync your device to its app or desktop platform. Review how battery was used over the ride. You can see graphs of battery vs. distance or speed. This helps you plan future rides (e.g. “I needed to use 45% battery for that route on eco mode”).
- Keep it charged: Remember, a computer with a dead battery is useless. Charge your Garmin/Wahoo/Karoo regularly. External charging packs can help on multi-day tours.
