The XCADEY Alpha 800 is an Android-based GPS bike computer (2 GHz quad-core, 2 GB RAM, 32 GB storage, 2,500 mAh, Android 8.1) that offers Karoo 2-class hardware at $159–$259, with a bright 3.2-inch 480×800 Blanview display, dual-band GPS, and roughly 20 hours of battery life. Reviewers agree the hardware, screen, speed, and value are strong, while the software is still maturing: navigation is basic, app/sync workflows were initially manual, and build/mount fit feels plasticky. Frequent firmware updates (every 2–3 weeks, through November 2026) have added heading-up maps, an app store, companion apps, and ClimbPro-style climb planning.
Pros

Cons
- Navigation is basic: only distance to next turn at the top, no arrows, and map stays north-oriented unless manually changed31
- Route loading and activity syncing were initially manual (GPX via cable, no Strava/Komoot sync), described as a time machine to 201514
- Cannot change route or ride profile while an activity is running31
- Build feels plasticky and somewhat hollow; mount fit is loose and the computer wobbles42
- Software still maturing from a small startup: some basics missing (e.g. importing your own workouts) and features arrive incomplete24
- Around 20 hours of battery is considered too short for bikepacking and multi-day rides2
- Large bezel around the screen; reviewer would prefer more screen and less bezel3
- No safety lanyard included, and no cable or mount in the box on the pre-production unit34

Reviews & Ratings
12:58The reviewer unboxes and briefly tests a pre-production XCADEY Alpha 800 GPS bike computer running Android. He notes it is a prototype with unfinished software, but sees potential in its large, fluid, and detailed display, and mentions it supports power sensors, Bluetooth, ANT+, Wi-Fi, offline maps, and a 3.2-inch touchscreen. He finds the build plasticky, the device gets warm, and the mount fit is loose. The companion app is not functional yet, and many features like navigation and radar support are incomplete.
08:58The reviewer presents the XCADEY Alpha 800 (referred to as 'Alfa 800' and 'Xcag' in the transcript) as a new Android-based GPS bike computer with a 3.2-inch TFT HD screen, dual-band GPS, WiFi, and Bluetooth. They highlight its fast performance, detailed offline maps downloadable directly via WiFi, smartphone-like touch interface, and long battery life, while noting some shortcomings like a large screen bezel, basic navigation prompts, and the lack of a lanyard. The reviewer considers it a very complete GPS at a launch price below 200 euros.
The reviewer, who is involved in the development of the Xcadey Alpha 800, describes it as an Android-based GPS cycling computer positioned more as a navigation device with sports functions, comparable to the Karoo. They note the device is under rapid development with updates every 2-3 weeks, and while the screen quality, build, and battery life are praised, navigation file loading and activity syncing remain manual and limited at the time of writing. A full review covering navigation, battery, sensors, and longer rides is planned later.
The XCADEY Alpha 800 is an Android 8.1-based bike computer (2 GHz quad-core, 2 GB RAM, 32 GB storage, 2,500 mAh) priced from $159 at launch to $259. Its hardware is similar to a Hammerhead Karoo 2 at a fraction of the price. Owners praise the fast performance, excellent GPS (comparable to a Garmin Edge 850) and a Blanview screen readable in direct sun at 25% brightness. Battery use is about 5% per hour (roughly 20 hours), enough for most riders but short for bikepacking. Software is developing quickly and XCADEY now runs a Discord for bug reports and feature requests. Releases through November 2026 added: - heading-up map mode and notifications on the ride screen; - an XCADEY Store with Komoot, and installing external Android apps such as Spotify or GPS Test (v3.1.9); - companion apps for Android and iOS; - ClimbPro-style climb planning, graphical data fields and larger numbers (v3.1.12). It can charge while running. Remaining gripes are a still-maturing software base from a small company, no way to import your own workouts yet, and a wobbly fit in a third-party Garmin mount.
