The best bicycle gadget depends on the job: an electronic horn helps you signal, a bike computer handles navigation and ride data, a radar tail light warns of approaching vehicles, an action camera records rides, and a Raspberry Pi can anchor a custom electronics project. These five picks, identified in a SlashGear roundup updated September 26, 2026, are different kinds of tools—not substitutes for one another. The roundup drew on cycling discussions and expert publications; it did not report a representative cyclist survey.
How to choose among these bicycle gadgets
Start with the problem you want to solve. If you need to make yourself heard, consider an electronic horn. For route guidance and training data, look at a bike computer. A radar tail light is for rearward vehicle alerts and visibility; a camera is for recording; a Raspberry Pi is for someone prepared to build a device. Check how each item mounts, what it works with, and whether it needs batteries, charging, or additional components.
1. Daway A14 electric bicycle horn for signaling
The SlashGear roundup describes the Daway A14 as an electronic horn with five selectable modes, a separate control switch, a universal bicycle mount, and two AAA batteries. It also reports a positive expert score from Ride Review, with a 4.3 average score. Those details and the score are reported by the roundup, rather than independently verified here. The “110 dB” in the product name should not be read as a guarantee of audibility or safety in every riding environment.

2. Garmin Edge 840 for navigation and training
The Garmin Edge 840 is the roundup’s pick for riders who want speed and distance data, navigation, and training features. SlashGear specifically mentions suggested workouts and multi-band GNSS, and reports that Cyclist included the Edge 840 among the best bike computers of 2024. The source for these Edge 840 details in this roundup is secondary; current availability and feature specifics are not established by an official product page among the cited sources.
A bike computer makes most sense when you will use its ride-data or route tools. Before choosing this model, confirm current device and accessory compatibility, mounting fit, and the features included in the version available to you.

The roundup presents the GoPro HERO12 Black as a camera option for riders who want to record rides, mentioning stabilization, waterproofing, and the possibility of handlebar or helmet mounting.

5. Raspberry Pi 5 for a DIY bicycle electronics project

The roundup suggests it as a starting point for custom projects such as a horn, lights, a vehicle-alert system, or a bike computer. Those examples require suitable additional components, assembly, and configuration; buying the board alone does not provide a finished, road-ready gadget.
