What does a smart electric bike actually do?

Smart electric bikes add GPS tracking, 4G cellular security, motor customization tools, and ride data tracking on top of standard electric assist. On the Aventon Current ADV and Current EXP, these features are bundled into the ACU (Aventon Control Unit), giving you real-time location visibility, anti-theft protection, and control over how the motor feels, all from the Aventon app. This article breaks down every ACU feature by category so you know exactly what you're getting.

A regular ebike vs. a smart ebike: what actually changes

A standard ebike gives you pedal assist and a display showing speed, battery, and assist level. That's it. You ride, the motor helps, and when you park, you lock it and hope for the best.

A smart ebike keeps working after you stop riding. The bike is connected to a cloud server through 4G cellular, so it can send you alerts if someone touches it, let you see exactly where it is, and accept commands from your phone, like remotely disabling the motor or locking the system.

While you're riding, smart features go further than just changing power levels. The motor responds to real-time sensor data from an IMU (inertial measurement unit) built into the frame. It knows whether you're climbing, how steep the grade is, whether your front wheel is about to lift, and whether you've just left the ground. That data feeds into features like Auto Assist, Wheel Lift Control, and Jump Tracking. None of these exist on a standard ebike, no matter how good its motor is.

What "connected" means in practice

When people say a bike is "connected," they usually mean one of three things: Bluetooth (short-range app control), GPS (location tracking with a phone or satellite), or 4G cellular (independent cloud connection that works without your phone nearby). The Aventon ACU uses all three, and they serve different purposes.

The Aventon ACU, explained

ACU stands for Aventon Control Unit. It's the integrated smart platform built into the Current ADV and Current EXP, combining 4G cellular, GPS, Bluetooth, a touchscreen top-tube display, and a wireless handlebar control pad into a single system.

The 4G connection links directly to Aventon's cloud servers. This means security features (motion alerts, remote tracking, motor lockout) work even when your phone is miles away. You don't need to be within Bluetooth range for the bike to send you an alert. The bike is always online.

GPS gives you continuous position updates. These feed into the Track My Bike feature in the Aventon app, which shows a real-time map of the bike's location whether it's parked, moving, or being moved without your permission.

Bluetooth handles the local connection between the bike and your devices: the Aventon app for ride data and tuning, your Apple Watch, and Bluetooth accessories like heart rate straps and action cameras.

4G, GPS, Bluetooth: what each layer does

The touchscreen display and wireless control pad

The touchscreen sits on top of the tube (not on the handlebar where it's easily dinged) and shows speed, assist level, battery, cadence, power output, grade, and fitness metrics in real time. The wireless control pad on the handlebar lets you change assist levels, switch modes, and trigger features without looking away from the trail.

Security features that come built in

Most riders don't think about ebike security until their bike disappears. The ACU is built around the assumption that a bike worth $4,599 needs more than a cable lock.

GPS tracking and Lost Mode

Track My Bike in the Aventon app shows a live map of the bike's position updated continuously via 4G and GPS. When you park, the position is recorded. If the bike moves, you know immediately.

If the bike is reported stolen, Lost Mode disables the motor assistance remotely via the cloud connection. The motor goes silent the moment the command processes, making the bike much harder to ride away on. When the bike shuts down, it auto-locks.

Unusual activity alerts and geofencing

Unusual Activity Detection sends an immediate push notification to your phone if the bike is touched, moved, or tampered with while parked. You don't have to be checking an app; the alert comes to you. If someone leans it over at a trailhead parking lot, you'll know within seconds.

Geofencing lets you set up to four zones: either restricted areas (the bike shouldn't leave) or allowed zones (the bike should stay inside). If the bike crosses a boundary, you get an alert and the system can apply restrictions automatically. This is useful for families with younger riders, or for keeping a work bike on campus.

The integrated e-lock

The ACU includes a power-on passcode that prevents the motor from activating without the code. You can also trigger a remote motor lockout from the app. The motor lock doesn't physically stop the wheels from spinning (it's not a wheel lock), but it makes the bike significantly less useful to someone who doesn't have the code or the app.

Ride performance you can actually tune

Security features protect the bike when it's parked. Performance features change how the bike rides when you're moving. The ACU gives you several tools here, and some of them are exclusive to the Current.

Ride Tune: customizing motor feel

Ride Tune lets you adjust the torque and acceleration curves for every assist level through the Aventon app. The motor doesn't have to behave the same way in PAS 1 and PAS 5; you can dial each one separately.

If you prefer a snappy, responsive feel for technical climbing, set the higher levels to deliver power quickly. If you want a smooth, natural feel closer to an analog bike for longer rides, pull the torque curve back. Changes apply immediately and stay saved to your profile.

Auto Assist and Boost Mode

Auto Assist uses the IMU to detect the current incline and adjust power output automatically. On a flat, the motor conserves battery. On a climb, it adds power before you have to reach for the assist level button. The effect is a more natural riding experience: the bike responds to what you're doing, not just what level you've selected.

Boost Mode delivers a 20% increase in torque for up to 30 seconds. On the Ultro X motor, that takes peak output from 750W to 850W and torque from 110Nm to 120Nm. Use it for one hard obstacle, a punchy switchback, or the last bit of a steep wall you didn't think you could clear.

Wheel Lift Control and OverRun (Current-exclusive)

These two features don't exist on other ACU bikes; they're built specifically for the Current's eMTB use case.

Wheel Lift Control monitors incline and motor output using the IMU. On steep pitches with a 110Nm motor, front-wheel lift is a real risk, especially for riders new to powerful mid-drives. Wheel Lift Control detects when lift is imminent and automatically reduces motor output to keep the front wheel grounded. It's a safety net that lets you run higher assist levels on technical climbs without worrying about flipping.

OverRun is subtler. When you stop pedaling, a standard ebike motor cuts off almost immediately. OverRun extends motor assistance briefly after your pedal stroke ends. On a trail with a root or rock where you physically can't pedal through without lifting your feet, that brief continuation of power is what gets the wheel over cleanly. It removes the jarring on/off feeling and makes the bike flow through technical sections more naturally.

Uphill Start Assist and Hold Assist

Uphill Start Assist detects incline and pedal torque at the moment you start pedaling on a hill. It provides an instant motor response that prevents rollback and makes steep starts feel effortless. On a 20% grade with a 56-pound bike, this matters.

Hold Assist engages when you're stationary on an incline. The motor maintains just enough output to hold the bike in place so it doesn't roll. Pause mid-climb to catch your breath without grabbing both brakes at once.

What the bike tracks on every ride

The ACU collects ride data continuously and displays it on the touchscreen. After rides, everything syncs to the Aventon app for a full breakdown.

Jump Tracking (Current-exclusive)

Jump Tracking is one of the Current's most distinctive features. The IMU detects when the bike leaves the ground (based on changes in gravitational force) and logs the jump automatically. Each jump entry shows air time, ascent height, takeoff angle, and landing angle.

For riders working on technical trail skills, the landing-angle data is directly actionable. A nose-heavy landing shows up numerically, not just as a feeling. You can compare jumps over time, see progression, and identify habits (consistent loop-out tendencies on bigger hits, for example) that are invisible without data.

Rider power, cadence, and left/right balance

The fitness display shows rider power in watts, cadence in RPM, torque, and left/right leg power balance in real time on the touchscreen. Leg balance is particularly useful: if you're consistently pushing 60% through one leg, that asymmetry shows up clearly. Runners, skiers, and anyone recovering from an injury often find this data more practically useful than heart rate alone.

Route sharing and global leaderboard

The Go feature captures your route using Bluetooth plus phone GPS for high precision. After the ride, it auto-generates a shareable ride card (not a raw GPX file, but a visual summary with stats) that you can send directly to friends or post.

Records and Rankings syncs your odometer through the cloud and places you on a global mileage leaderboard. Daily, weekly, and yearly totals are tracked. For riders who are motivated by visible progress, seeing a running total that updates with every ride has a different effect than an app stat buried three taps deep.

The connected ecosystem

The ACU connects the bike to your other devices, not just your phone.

Apple Watch integration

Pair an Apple Watch to the ACU and you can control the bike's power and locks from your wrist. The watch also displays speed and distance and syncs heart rate data directly, tying your cycling output to the same health dashboard where you track sleep and workouts. You don't need to pull your phone out of your pocket to lock the bike when you stop.

Action camera control for DJI and GoPro (Current-exclusive)

The Current ADV and Current EXP support Bluetooth control of DJI and GoPro action cameras from the bike's wireless control pad. Start and stop recording, take photos, and switch modes without reaching for the camera or fumbling with a mount. On a moving trail, having camera control on the handlebar button isn't a luxury; it's the only practical way to capture anything without taking your hands off the bars at the wrong moment.

OTA updates: features that arrive later

Over-the-air firmware updates mean the bike gets better after you buy it. Aventon pushes algorithm improvements, new mode options, and feature additions wirelessly. Boost Mode, Uphill Start Assist, and other features were added to earlier ACU bikes via OTA after launch. When you buy a Current, the feature set you see today isn't necessarily the final one. That's a meaningful difference from a bike with a fixed motor controller that will never change.

Smart features on the Current ADV and Current EXP

Both the Current ADV and EXP run the full ACU feature set described above. The difference is in the hardware around it.

Current ADV: $4,599

Built around a 6061 alloy frame with RockShox Psylo Gold 150mm fork and Deluxe Select+ shock, SRAM Eagle 70 12-speed transmission, and SRAM DB8 hydraulic brakes. The Aventon Ultro X motor delivers 110Nm of torque (120Nm in BOOST) from a 750W peak motor, paired with an 800Wh integrated battery rated for up to 105 miles. Weighs 56 lbs. Maxxis Minion DHF/DHR II 29x2.5"/2.4" tires, tubeless ready. Class 1 by default, convertible to Class 3 via the app. UL Certified. Colors: Blue Onyx and Camouflage.

Current EXP: $5,999

Shares the same motor, battery, range, and ACU platform as the ADV. The upgrade is in the frame and components: carbon front triangle with alloy rear, RockShox Lyrik Select 150mm fork and Super Deluxe Select+ shock, SRAM S1000 Transmission drivetrain, and SRAM Maven Base 4-piston hydraulic brakes. Weighs 53 lbs. Colors: Glacier Mint and Midnight Black.

The EXP is lighter, stiffer at the front end, and more precise on technical terrain. The smart features are identical across both builds.

Both models undercut direct eMTB competitors on price. Trek Rail+ 5 ($6,099) and Specialized Turbo Levo Alloy ($6,099) offer motor companion apps, but neither includes Jump Tracking, Wheel Lift Control, OverRun, or action camera integration. The Current covers the smart-feature gap while coming in $500–$1,500 lower.
