Cars & bikes electronics that arrive when your project needs them
Whether you are fitting a dash camera in a commuter car, adding auxiliary lighting to a bakkie, or building an e-bike controller for a university project, having reliable local stock changes everything. Communica stocks practical components - batteries, power regulators, fuses, connectors, sensors and enclosures - with fast collection from our Samrand head office or Cape Town and Pretoria branches, and VAT-compliant invoices for school, tertiary and procurement records.
Why local availability matters for cars & bikes projects
Lead times for vehicle electronics can disrupt workshops and fleet upgrades. We prioritise commonly used parts so you can replace or prototype without waiting weeks. For branch locations and hours, check our branches page to plan pickup: Branches & Trading Hours.
Core categories useful for car and bike work
- Power conversion: buck/boost regulators and automotive DC-DC modules for 12V/24V systems
- Protection: blade fuses, resettable polyfuses, in-line fuse holders
- Connectors & cabling: sealed automotive connectors, ring terminals, heat-shrink tubing
- Sensors & interfaces: hall-effect current sensors, wheel-speed sensors, temperature probes
- Mounting & enclosures: IP-rated boxes, DIN-rail adaptors and vibration-damping mounts

Quick spec callouts to check before you buy
Two practical checks save workshop time: voltage compatibility and continuous current rating. Use Ohm's and power basics when sizing wiring and regulators:
Formula: P = V × I - where P is power (W), V is voltage (V), I is current (A). For example, a 12V LED bar drawing 6A needs at least a 72W supply and wiring rated above 6A with margin.
| Component | Typical spec | When to choose |
|---|---|---|
| Automotive buck regulator | 12V in, 5V/3A out | Powering dash electronics from car battery |
| DC-DC isolator | 24V to 12V, 10A | Trucks and rooftop accessories |
| Hall current sensor | ±50A, analog output | Battery management and motor controllers |
