Bontrager DuoTrap S

Easy assembly and works as it should

Pros & Cons

Great experience on the site and quick ordering. The products are clearly presented.

Die Bestellung war problemlos. Die Lieferung war schnell. Das Produkt entspricht genau meinen Erwartungen.

Easy to mount and connect to your bike computer. Does what it needs to do

Pros & Cons

I have only found one app that can communicate with the sensor via Bluetooth.

Pleasant and very easy to use. Duo staircase does not need to be turned on or off.

Pros & Cons

After six or so rides, I get the signal that the battery is low. Installed around March 10, today replaced the battery with a new battery. Result no more operation of sensor, led lights no longer respond to magnet. The Duotrap does not close completely against the frame the tail of the sensor points about 3 degrees towards the spokes. Can be remedied by removing the rubber sealing ring around the sensor. During bike rides it gave an impression of accurate operation speed and cadence.

Pros & Cons

Quick and easy to install

Pros & Cons

Sensor readings work as expected, cadence band was somewhat of an awkward fit. The sensor is only connected with a single bolt, weirdly enough, which seems a bit of a weak connection.

Pros & Cons

The Bontrager Duotrap S attached to my diamond 137 gravel bike. Cumbersome mounting. When changing the battery, the complete sensor must be removed. Works with my Garmin Edge 810.

Pros & Cons

Really meets me expectation

Pros & Cons

Ultra happy with this product which is discreet, light and easy to install. calibrates itself

Pros & Cons

Easy to install in the dedicated space. However, the sensor tends to pop out as soon as the screw is tightened, and the gasket seems ill-suited. Perhaps it depends on the type of frame...

Pros & Cons

Good speedometer

Pros & Cons

Installation took some looking around. Didn't find the manual super clear. But once you get the hang of it, it's pretty easy. Pairing with the Garmin also went fine. Nice magnet holder on the pedal (and 3 choices of thickness). I find the screw of the magnet to the spoke quite long. This makes it run pretty close past the sensor.

Pros & Cons

i can't get it paired with bleutooht on cell phone

Pros & Cons

Makkelijk gemonteerd in mijn Trek bike. Eenvoudige herkenning/koppeling aan fietscomputer. Snelheid en cadans aanduiding is uitstekend.

Pros & Cons

The Duotrap stops working after two years. Battery replaced and reinstalled but unfortunately no more cadence/speed measurement. The red and green lights are on. What now?

Works perfectly. Attaching in the intended frame holder goes easily, however, it does not seem as tight as I imagined. Holds but flawlessly, even on bumpy roads.

The whole thing works fine. And neatly tucked away. But do NOT select "cadence sensor" from your Garmin. Because then it will be found, but it does not work. Select "cadence/speed sensor". Then it will find it under a number instead of a name, but it will work.

Pros & Cons

Very easy to install and is recognized right away Top product
