ROX 4.0 - GPS Bike Computer mit Höhenmessung
Der ROX 4.0 GPS Fahrradcomputer unterstützt Fahrradfahrer mit seinen 30 Funktionen und seiner Bedienerfreundlichkeit auf der Fahrradtour, so dass diese sich auf das Wesentliche konzentrieren können: Den Spaß am Fahrradfahren. Das extra große Display zeigt Daten wie Höhenprofil, Geschwindigkeit, Distanz und Trainingszeit zuverlässig an. Navigationshinweise und die Kopplung an das E-Bike und externe Sensoren sind für den ROX 4.0 Bike Computer selbstverständlich. Dank der kostenlosen SIGMA RIDE App lassen sich die aktuellen Fahrdaten jederzeit über die SIGMA RIDE App auf dem Smartphone verfolgen und analysieren.

Herausragendes Display
Das kontrastreiche Display ist aufgrund seiner 2,4 Zoll Diagonale und der extra-großen Ziffern auch während der Fahrt sehr gut ablesbar. Ein spezieller Red Circle oben rechts im Display ist farbig unterlegt und bietet Fahrradfahrern eine innovative und spannende Darstellung ihrer Trainingsdaten. In Kombination mit der kostenlosen SIGMA RIDE App für das Smartphone können individuelle Displayansichten mit wenigen Klicks eingestellt werden - es sind bis zu sechs Screens mit jeweils drei Werten konfigurierbar. Aktuelle Geschwindigkeit und Uhrzeit werden dauerhaft auf dem Display angezeigt.

Jederzeit startklar
Der ROX 4.0 Radcomputer wird mit wenigen Handgriffen direkt am Lenker positioniert - ganz ohne Kabel und Sensoren. Wer möchte, kann den Rox 4.0 mit zusätzlichen Sensoren zur Messung von Geschwindigkeit, Herzfrequenz und Trittfrequenz koppeln. Nach dem Einschalten ermittelt der ROX 4.0 in Sekundenschnelle mittels GPS und GLONASS die Position des Radfahrers. In Kombination mit der intuitiven Bedienung durch drei Tasten kann die Fahrradtour sofort starten.

Barometrische Höhenmessung
Ein echtes Highlight beim ROX 4.0 ist der integrierte Luftdrucksensor. Mithilfe dieser barometrischen Messung liefert er Bikern zuverlässig Informationen über die Höhe, ermittelt Steigungen und Gefälle und ermöglicht damit eine präzise Aufzeichnung der Route. Auch ein grafisches Höhenprofil kann auf dem ROX 4.0 abgerufen werden. Die Starthöhe am Beginn der Tour lässt sich automatisch per GPS kalibrieren oder kann wahlweise manuell eingestellt werden.

SEARCH & GO - die clevere 1-Punkt Navigation
Mit der „Search & Go-Navigation“ können Radfahrende schnell einen beliebigen Ort finden und dorthin navigieren. Dazu geben sie in der SIGMA RIDE App auf dem Smartphone entweder eine Adresse ein oder klicken einen beliebigen Punkt auf der Karte an. Präferenzen zu den Wegen (Radwege, unbefestigte Wege, Straßen oder Lauf- und Wanderwege) können individuell festgelegt werden. Der erstellte Track lässt sich anschließend direkt auf dem ROX 4.0 starten oder für später in der SIGMA RIDE App speichern.

Tracks von Dritten importieren
Radfahrer importieren über die SIGMA RIDE App flexibel Tracks aus dem SIGMA DATA CENTER oder aus Portalen wie beispielsweise Komoot und Strava. Der gewählte Track lässt sich sofort starten oder er kann auf dem ROX 4.0 gespeichert und zu einem späteren Zeitpunkt offline abgefahren werden. Auf diese Weise navigieren Radfahrer auf ihrer Tour, ohne dass eine Verbindung zum Smartphone bestehen muss.

Externe Sensoren
Wer noch mehr Daten oder eine noch höhere Genauigkeit seiner Werte ermitteln möchte, kann Dank ANT+ und BLE auch externe Sensoren wie Geschwindigkeits-, Herz- und Trittfrequenzsensoren an den ROX 4.0 koppeln und hat auf Wunsch alle Daten im Blick.

E-Bike ready
Der ROX 4.0 ist E-Bike ready und lässt sich kinderleicht mit vielen E-Bikes koppeln. Der GPS Bike Computer verbindet sich mit dem kompatiblen E-Bike-System und zeigt die aktuelle Unterstützungsstufe, Batteriestatus, Licht und weitere Daten auf dem Display oder im Red Circle an.

Bequeme Datenauswertung
Mit der SIGMA RIDE App werden Trainingsdaten via BLE vom ROX 4.0 zum Smartphone transferiert und gesammelt. Die wichtigsten Daten und Statistiken lassen sich mit farbigen Datenfeldern übersichtlich darstellen, jederzeit auf dem Smartphone ablesen und bequem auswerten.

Flexible Montage
Der ROX 4.0 wird mit der herkömmlichen GPS-Lenkerhaltung ausgeliefert. Diese Disc wird mit Kabelbindern wahlweise auf dem Lenker oder Vorbau des Rades montiert und der ROX 4.0 durch Eindrehen mit einem Klick fixiert.

Fantastic!
Color: Light Grey, Size: Pack of 1, Color: Light Grey, Size: Pack of 1
Outstanding quality and incredibly easy to assemble! The back support is a perfect 10/10. I was debating between the M57 and the B100, and the B100 definitely won me over. The materials feel premium and durable. Highly recommended!

Comfortable. Great Value for money. Easy to assemble. Great customer service.
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I've been looking for a new chair to replace a cheap $30 chair i bought off of Amazon last year that had been killing my back and shoulders. I wanted something in the $150-$200 range and settled on the M18. Shipping was a fast 3 days with Prime and the box arrived in great condition. All parts were separately wrapped or in their own boxes. Came with all hardware and nothing was missing. Assembly took me a little longer then normal because i have rotator cuff injury in my left shoulder so that arm is mostly useless. The most difficult part for me was attaching the wheels to the base. Other then that it was simple. Once the chair was assembled i sat in it for the first time and started making my adjustments with the recline feature, armrest level along with the headrest. Next i reached around for the lumbar support knob and tried to adjust it but with my bad shoulder i decided to just get out of the seat and turn it around and adjust it with both hands. After spinning the chair a round to get at the lumbar knob i noticed a large crack in the plastic in the middle of the back of the lumbar plastic piece. I had not made any lumbar adjustments yet so i assumed this is how i received it. The lumbar support comes preinstalled to the backrest so it either was damaged before or during the shipping process. Either way it was damaged before being delivered to me. The lumbar support still functioned properly but it was still broken. I decided to contact Sihoo's customer support that came along with the installation instructions regarding the damaged lumbar piece. I received a reply the next day and after sending them some more info about my order and a couple pics they shipped me a replacement part which took a week to arrive. I swapped out the damaged part and after owning the chair for a week so far i am really happy with my purchase. Im about 5'10 180lbs. At its highest height level my feet reach the ground comfortably flat footed. The backrest fully covers my back and the headrest adjusts very well to sit on the back of my lower head/upper neck. The armrests only go up and down....not forward and back or tilt inwards. This is fine for me as they are grooved to fit your forearm while sitting at your desk/keyboard. The armrests are also a soft cushioned rubber material...not a hard plastic. The mesh of the backrest and headrest are good material and seem well made. The seat is very wide and the cushioning is firm which i prefer. Usually more firm cushioning seems to last longer and hold its form. The base of the chair is VERY sturdy and made of all metal. My chair is on carpet and holds its position very well. As far as recline goes you can set it to recline all the way back, half way or lock the chair in the upright position. You can also adjust the resistance on the reclining feature. So that being said im very happy with my purchase. It arrived with a slight flaw which the company corrected in a fast manor and was very polite in their customer support. I personally don't have a lot of experience with many office chairs and have never used a high end chair($500-$1000+) chair before to make any comparisons. All my chairs for the most part have been from local stores like Staples or Office Depot. Id recommend this over anything they carry in this price range....and i went and looked at their products before buying this chair as well.

SIHOO M18 chair is amazing
Color: Black, Size: Pack of 1
I purchased the SIHOO M18 Ergonomic Chair a few years ago and have really enjoyed it. It’s very comfortable and offers multiple adjustments, whether you want to recline and relax or sit upright for work. The back support is also excellent, and I haven’t had any issues with the chair at all. You can easily tell it’s high quality from the build and appearance—no creaks or noises whatsoever. I highly recommend this chair to anyone in the market for a new office chair.

Good budget-friendly option
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
The chair arrived 4 days early and was easy to put together by following the instructions carefully. It feels sturdy and comfortable. It does support the lumbar region of the back and the arm rests are adjustable vertically as well as the head rest. I wish the arm rests were able to rotate in and out for added customization and that the back of the chair could be adjusted up and down for more precise support. But for a budget chair, it does a good job.

A solid chair for the budget conscious sitter.
Color: Black, Size: Pack of 1
While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.
