Small yet mighty.
The new Lezyne Mini GPS HRSC Loaded Bike Computer may look similar to its predecessor, but adds a massive range of functionality that's otherwise unheard of in computers at its price point. The most notable change is the advent of Bluetooth compatibility, which was previously only employed by its decidedly non-mini compatriots such as the Super and Power GPS models. This update upgrades the Mini GPS a full-fledged head unit status, opening up wireless access to power meters, heartrate monitors, and any other ancillary device that speaks Bluetooth. This particular Mini's HRSC Loaded designation means that it also comes packaged with everything you need to start gathering training data related to heart rate, speed, and cadence.
Lezyne's Cadence Speed Flow Sensor combines cadence and speed into a single lightweight unit that communicates seamlessly with the Mini via Bluetooth. Its use of a rare earth magnet helps extend the range of engagement, eliminating the will it/won't it anxiety of the millimeter spacing between sensor arm and spokes required by other sensor suites. This lets you take full advantage of the versatile mounting and adjustable swing arm, and an LED power indicator warns when the unit needs a nap.
The included Heart Rate Flow sensor also communicates with the Mini via Bluetooth, and features a soft, comfortable band that's a far cry from traditional, uncomfortable plastic models. Its LED indicator lets you know when the CR2032 battery's running on fumes, which is easily replaceable with a quick jaunt to the nearest convenience store.
With Bluetooth comes the link to the ever-present smartphone, and the Mini GPS takes advantage by using Lezyne's Ally app to provide the kind of smart services that let us turn off our own head units and shuttle all the blood to our legs. With Lezyne Ally you can enable live tracking for anyone who wants to follow your ride, get live segment alerts from Strava, translate ride maps into turn-by-turn prompts, and sync with third party sites like Strava and TrainingPeaks. It also displays text and call notifications so you can screen your messages and decide which ones merit a quick roadside lean session.
The Mini GPS's ride mapping features carry over from last year, demonstrating once again that this head unit is mini in stature only. Its out-sized feature list includes displaying speed, three different ride-related times, trip distance, odometer distance, elevation gains and losses, current elevation, laps, temperature, battery life, and even the strength of the GPS signal it's using to track all of that. In short, it's virtually every measurement you need to map yourself on a bike.
It has the capacity to store up to 100 hours of this data, and it now collects data for 12 hours at a time instead of 10. If you're unit is approaching full or you're just anxious to compile your numbers, the GPS Mini plugs into any USB port with a provided cable. Your ride stats can then be uploaded, automatically mapped, and converted to an analyzable data set on the free database on Lezyne's homepage. That site made the previous Mini GPS's data dumps among the simplest that we've come across; the latest generation's Bluetooth connectivity makes them even easier.
The high-resolution display may lack the bling of colorful touchscreen options, but it also doesn't wash out under sunlight and has a backlight function for visibility during early morning spins and under looming rainclouds . You can also toggle between km and miles in the menu, which eliminates the need to laboriously pore over giant, unfolding, multi-language manuals or perform complex button hold maneuvers in order to check your trip distance in metric terms. All of this functionality perches securely atop your bar or stem with Lezyne's included X-Lock bracket.
