CHIGEE SR-1 Millimeter-Wave Radar System

CHIGEE SR-1 Radar System – Eyes Forward. Radar Watching Your Back.

The CHIGEE SR-1 brings advanced 77GHz millimeter-wave radar technology to motorcycles, giving riders an extra layer of awareness for what’s happening behind them.

Designed specifically for motorcycles — not adapted from automotive systems — the SR-1 constantly monitors the area behind and beside your bike, helping alert you to vehicles in your blind spot, fast-approaching traffic, unsafe lane changes, and potential rear-end collisions.

Four Active Warning Modes

The SR-1 runs four intelligent warning systems simultaneously:

• Blind Spot Detection (BSD)
  Detects vehicles sitting in your blind spot before changing lanes.
• Lane Change Assist (LCA)
  Warns of fast-approaching vehicles from behind before you move across.
• Rear Collision Warning (RCW)
  Detects rapidly closing vehicles approaching from the rear and triggers high-priority alerts.
• Active Overtake Alert (AOA)
  Helps prevent cutting back in too early after overtaking another vehicle.

Designed Specifically for Motorcycles

Unlike many radar systems adapted from cars, the SR-1 has been engineered around real motorcycle riding conditions.

The compact radar module uses:

• 77GHz automotive-grade radar technology
• Up to 70 metre detection range
• IP68/IP69 waterproof rating
• 2Tx / 4Rx antenna configuration for improved accuracy and responsiveness.

Visual & Audible Alerts

The SR-1 includes:

• Rear radar module
• LED blind spot warning indicators
• Active rear warning functionality to help alert approaching drivers

When paired with a compatible CHIGEE display, radar information can also be shown directly on-screen with optional audible alerts.

Upgrade Your SR-1 with CG BSD Radar Mirrors

Want a cleaner, more integrated setup?

The SR-1 can be upgraded with the optional CHIGEE CG BSD Radar Mirror Kit, which integrates the radar warning indicators directly into your mirrors instead of using separate external warning lights.

Benefits include:

• Cleaner cockpit appearance
• More OEM-style integration
• Warning alerts positioned naturally within your peripheral vision
• Reduced handlebar clutter

Choose between:

• Round Mirror Design
• Angular Mirror Design

⚠️ Please note: The CG BSD mirrors are an optional upgrade and are not included with the SR-1 radar kit.

The ABT Take

This is one of the most interesting motorcycle safety products we’ve seen in a long time.

It’s not designed to replace rider awareness — nothing does that — but it absolutely adds another layer of information in busy traffic and motorway riding.

And unlike many motorcycle gadgets that feel gimmicky, the SR-1 feels like genuine rider technology. Compact, smart, and properly thought through.
