Why the Garmin Varia Changes the Cycling Experience
Many cyclists underestimate the mental load of monitoring traffic while riding. Even a single near-miss incident can shake confidence and make riders hesitant. The Varia helps eliminate that tension by:
- Providing real-time alerts for approaching vehicles.
- Allowing cyclists to focus on the ride rather than constantly looking over their shoulder.
- Helping you choose safer lines on the road, avoiding debris or obstacles near the shoulder.
As noted by cycling journalist Tara Seplavy, after a scary encounter on her usual route, using radar “helped me regain confidence and ride more comfortably.” This sentiment is echoed by countless riders who find it nearly impossible to go back to riding without radar once they’ve tried it.
