SmartHalo review: Minimalist smartphone-connected device protects, motivates, and informs bike riders

For $149 you can add modern functionality to your pedal bike, powered by your smartphone. The SmartHalo removes the distractions of your phone with a simple central display.


Bike mounts for your smartphone help you navigate, communicate, and track your fitness. Bike lights illuminate the path ahead and make you visible to others. Chains and cables secure your bike from theft.

All of these take up valuable space on your bike and can cost quite a bit. The new SmartHalo offers all of this in a single device that sits right at the center of your handlebars.

While I enjoy running as one form of exercise, cycling is more fun and gets me further at a faster speed. My 1993 Bridgestone XO-4 continues to help me knock out 32 mile regular commutes and the SmartHalo adds 2017 tech to a 24-year-old bike.

Installation and pairing

The first step to use SmartHalo is to download and install the app on your iPhone or Android device. The app will then walk you through the step-by-step process to secure SmartHalo to your bike and get started riding with the SmartHalo features. There are several steps because you will be securing the SmartHalo in a manner that it cannot be removed by anyone as it provides an advanced security system. It took me about 15 minutes to get the SmartHalo mount installed on my bike.

My bike required use of the provide spacers on the handlebars to ensure a secure fit. It is important to pay particular attention to the graphics on the setup screens since the parts will fit on either side of the center handlebar connection, but they are designed for only one side. There are templates to help you confirm your arrangement and sizing and it is one of the most impressive installation guides I have ever seen.

After the mount is attached, you clip the SmartHalo into place and then secure it using the HaloKey. The HaloKey is a customized key that fits into the impression on the right side of the SmartHalo and unlocks the attachment from the mount.

The SmartHalo charges up via a microUSB port on the back side that has a rubber port cover. The SmartHalo should last about three weeks.

After installation, setup your account and then connect the SmartHalo to your phone to start using the device.

Functions and smartphone software

There are five primary functions of the SmartHalo: navigation, light, alarm, fitness, and assistant. Let's take a closer look at each function.The navigation feature is designed to help reduce your focus on your smartphone display, which can be dangerous when riding your bike. You use your smartphone to enter your destination and setup the route, but then should put your smartphone away in a bag or pocke and let SmartHalo help you navigate. SmartHalo uses OpenStreetMap for plotting your course and currently doesn't offer path options or waypoints. The software will try to find you the best path using bike paths and trails though.

As you start riding, the SmartHalo will use the LED lights to guide you. As you approach a turn the lights will start out as wight and then change to green the closer you get to a turn and in the quadrant where you need to turn. It will flash green for the actual turn event. If you see it turn red, then you missed a turn and should turn around.

Since I have an established path on trails for my commute, I like using the fairly new compass mode that just indicates where your destination is in relation to where you currently are. Different colors orange, yellow, and green, give you a sense of how far away you are from your destination. You can also open up the app to show you where your bike's last known location was, in case you forgot where you parked it.

The light feature is pretty basic with an LED light on the front of the device shining in either automatic mode or manual mode. A double tap on the SmartHalo face will toggle the light on and off again. Auto mode will turn on the light when the sun sets and you are moving the bike. When you stop moving then the light will turn off automatically, there is nothing you ever have to do to have your light turn on or off. There are two light bulbs in the front and they are fine for many situations.

However, I ride on very dark trails and don't find the lights enough to replace my dedicated front light so I supplement it with my rechargeable light. I would love to see a more powerful light option on the SmartHalo. I set the SmartHalo on blinking mode for awareness of me riding while my own light is used for seeing the path ahead.

There is a funny episode with the alarm that you can read below in my daily experiences. The alarm functionality itself may be enough capability for you to consider the SmartHalo for your bike. The automatic alarm can be set to lenient or vigilant, which dictates how much movement is tolerated before it sounds.

If you park your bike in a public rack, you may want to set it to lenient so that others moving their bikes out of the rack don't set off your alarm. You can setup a custom tap code to toggle the alarm on or off in case your phone dies or is disconnected. This makes the alarm an important function that does not require a smartphone connection to be effective.

With the alarm activated, as long as your phone is not within the vicinity of your bike and connected via Bluetooth, your bike alarm is set. If someone starts jostling or moving your bike, the internal motion sensor is activated and alarms start sounding. I've seen several videos online where a very loud alarm with red lights will scare most thieves away, especially if your bike is parked in a public location.

I personally would still lock your bike up with some kind of cable or chain, but this additional protection should help prevent theft. Someone could always pick up your bike and throw it in a truck or something, but the alarm will sound until SmartHalo dies or is smashed to pieces.

The fitness feature lets you set time, distance, speed, calories, and CO2 savings goals for your bike rides. I usually have some kind of wearable on so use those to track GPS and calories burned and have a set distance to achieve with my commute, but found the speedometer goal quite useful.

You can set a speed, I chose 16 mph, and then see an indication of that speed around the outside of the SmartHalo display from green to red. With a 16 mph goal, each segment shows 4 mph increments of speed so it was easy to quickly see if I needed to speed up to achieve my goal.

The SmartHalo LED lights change in pink color as your other goals are tracked and achieved. The pink lights start at the bottom and work around the SmartHalo in a clockwise manner.

You can also toggle on the fitness function without setting a goal and just let the SmartHalo an dyour phone work together to track the duration, distance, average speed, calories burned, and CO2 spared with each ride. The lifetime stats show interesting summaries with averages, records, and more.

The last feature available is called assistant and shows different flashing patterns in blue light at the center of the SmartHalo display. These notifications are for calls or text messages. This could be useful if your phone is put away and you are expecting an important call. For example, I carry around a phone for marine salvage incidents and it is vital that I answer the call when it comes in. You can toggle on the sound and also the volume level in the assistant settings.

Daily experiences

There is no traditional on/off switch for SmartHalo. It will turn on automatically as you approach it and as you leave. The first day I went riding I took it off the charger in my office and started carrying it to the garage to mount to my bike. I forgot I had turned off Bluetooth on my phone so the alarm kicked in and started loudly blaring. Keep in mind, this was at 4:30 am so I wasn't popular with the family that day. If you need to travel with the SmartHalo or need to turn it off, just make sure to toggle off the alarm before doing so.

I also quickly learned that SmartHalo will track your fitness while connected and moving, even if you are going 65 mph on the commuter train while standing next to your bike. I could never ride my bike 65 mph and it would be great to see some kind of upper speed limit setting so that fitness would not start if your speed was too fast. Make sure to only toggle on the fitness function when you are ready to ride your bike, unless you want to track other movements too.

While I often commute with my RadCity electric bike, I also like to ride my traditional bike for the exercise benefit and the fact that it is lighter and easier to maneuver on the Sounder train. There are some great features on the SmartHalo and the fact that it reduces the distraction of your phone mounted in a carrier is great. It provides the essential functions that people commonly use with their bikes while having a battery that lasts for weeks.

I see on the SmartHalo blog that app updates have been released to improve navigation and Bluetooth connectivity while also adding in the compass mode. With the ANT+ support, I would love to see the ability to wireless connect my cadence tracker to the SmartHalo and then have a visual indicator for my cadence goal. I tend to ride to a cadence goal more than a speed goal so will pass along this request to the SmartHalo team.

The SmartHalo is lightweight and the visual indicators work well. There is quite a bit of capability packed into this $149 device and bike commuters will love the simplicity and functionality.
