Quectel Showcases Two-Wheeler Dual Radar Solution with 220m Forward Detection
At the 2026 China Motorcycle Expo in Chongqing, Quectel presented a two-wheeler dual radar solution: the AM100TA-MT forward radar (76-79 GHz, 220 m range, 5 cm accuracy) and the AM102AA-MT rear radar with BSD/LCW/RCW, already being designed into new models with leading two-wheeler brands.
From 19 to 22 September 2026, the 24th China International Motorcycle Trade Exhibition (CIMA Motor) took place at the Chongqing International Expo Center. At booth 3T09 in Hall N3, Quectel presented a forward-plus-rear millimetre-wave radar solution for high-speed two-wheelers, together with a clear commercial status: cooperation agreements are already in place with several leading motorcycle and two-wheeler brands, and the solution is being fast-tracked into their next-generation vehicle programmes. For OEMs and Tier 1s, that makes it a shortlist-ready radar option.
The Real Two-Wheeler Problem Is Perception, Not Handling
Passenger cars entered the ADAS era long ago; the two-wheeler transition is more pragmatic — it is first and foremost about rider safety. Vehicles closing fast from behind, figures emerging suddenly from a side blind spot, and visibility blurred by rain or fog form a high-risk map for riders. Vision alone struggles under difficult lighting, bad weather or high relative speed.
This is where millimetre-wave radar earns its place: it does not depend on light, ignores rain, fog and dust, and measures range, speed and azimuth directly, extending perception beyond human physiological limits. Quectel's forward plus rear combination forms a coordinated perception network covering the critical blind zones fore and aft, rather than a single-function part.
Forward Radar AM100TA-MT: 220 m Detection, 5 cm Range Accuracy
The AM100TA-MT targets the core requirement of high-speed riding — forward collision warning (FCW) and target detection. On national roads or expressways, when the vehicle ahead brakes suddenly or a stationary obstacle appears, human reaction time is a physical limit. Operating in the 76–79 GHz band, the radar can reliably detect targets at up to 220 metres with range accuracy as fine as 5 centimetres, reporting the position and motion state of up to 40 targets in real time to buy the rider a braking or evasive window.
On the engineering side, the forward radar uses slot-waveguide antenna technology and LOP packaging to improve signal-to-noise ratio and extend detection range, with thermal and EMC design addressing reliability under continuous vibration and harsh temperatures.
Rear Radar AM102AA-MT: BSD, LCW and RCW in One Unit
The rear radar addresses hazards that riders overlook, integrating blind spot detection (BSD), lane change warning (LCW) and rear collision warning (RCW). When changing lanes it sees through the visual blind spot and captures fast-approaching traffic up to 100 metres behind and to the side; when a vehicle closes at high relative speed, the system decides within milliseconds and triggers audible and visual alerts, freeing the rider from constant shoulder checks and mirror watching.
The published specifications of this model are summarised below for comparison against the vehicle's perception architecture:
- Operating frequency: 76–79 GHz
- Detection range: 0.5–100 m (@ 10 dBsm)
- Horizontal field of view: -60° to +60°; vertical field of view: -10° to +10°
- Operating temperature: -40°C to +85°C
- Ingress protection: IP67
Why Two-Wheeler Radar Is Harder Than Shrinking an ADAS Radar
Treating two-wheeler radar as a scaled-down automotive radar underestimates the engineering. For passenger cars, Quectel's central-computing satellite architecture pairs one forward 4D imaging radar with four corner radars on 8Tx/8Rx single MMIC chips, feeding raw point clouds into a central domain controller for unified alignment and fusion. Two-wheelers face a different set of constraints:
- Package size and mounting space: available real estate on a motorcycle or e-scooter is far tighter than a bumper, which is why the forward radar uses LOP packaging.
- Sealing and weather resistance: mud, heavy rain and continuous vibration are normal, and the solution is rated IP69 and IP67.
- Assembly cost: the design requires no manual bolt-and-torque calibration within installation tolerance, cutting line time and integration effort at the OEM.
- Power and electrical architecture: with limited battery and harness headroom on a two-wheeler, the solution includes a sleep/wake low-power design.
HSY Perspective
HSY represents Quectel's full portfolio, and two-wheeler radar is one of the categories where customer enquiries have grown most this year. Based on this solution, we suggest the following sequence.
Fix the function list before arguing about radar count. FCW and BSD/LCW/RCW map to two different part numbers (AM100TA-MT forward, AM102AA-MT rear); they are not one radar switched by software. If a customer is also planning radar-vision fusion with an AI camera — Quectel already offers a 1V1R configuration covering lane departure warning, headway warning, traffic sign recognition and speed limit alerts — plan mounting positions, orientation and harness routing for both sensors at architecture stage to avoid structural rework later.
Write ingress protection and assembly tolerance into the specification. IP69/IP67 and calibration-free mounting are the two-wheeler-specific value points, and they are hard indicators OEMs use to judge a supplier's engineering capability. Ask for the corresponding test reports at RFQ stage.
Track design-in status, not just datasheet figures. Quectel's cooperation with several leading motorcycle and two-wheeler brands, with the solution entering next-generation vehicle programmes, indicates these parts are in live project validation. Samples, evaluation boards or datasheets can be requested through HSY's standard selection channel; for front-fitment programmes, we recommend aligning schedule and capacity reservations with Quectel early.
