The ROX 4.0 has over 30 functions offering all the data you need such as altitude profile speed distance and training time. The outstanding 2.4 inch display is very easy to read even when the bike is moving. A genuine highlight of ROX 4.0 is the integrated air pressure sensor that uses barometric readings to determine inclines and declines. Providing you with reliable information about altitude and generating a precise record of your route. ROX 4.0 shows navigation and can automatically connect with your e-bike and external sensors for measuring speed heart rate and cadence.

Large Display: The 2.4-inch-diagonal high-contrast display and extra-large numbers make it easy to read even during a ride.

Red Circle: The innovative Red Circle on the upper right corner of the display is highlighted in various colours and offers innovative interesting display of training data.

Everything At a Glance: The SIGMA RIDE app allows you to set your display view individually. You can set up to six views each with three values. Current speed and time are shown continuously on the display.

Ready to go Any Time: The ROX 4.0 bike computer can be positioned directly on the handlebars in a few easy steps- entirely without cables or sensors. If you want you can connect your Rox 4.0 to additional sensors for measuring speed heart rate and cadence. Your ROX uses GPS and GLONASS to determine your position within a few seconds of being switched on. The user-friendly operation with three buttons enables you to start a bike tour right away. You can use the SIGMA RIDE app to set your individual display views.

Perfectly Positioned: The Overclamp Butler enables you to perfectly align your ROX 4.0 bike computer even if you have a short stem. The computer head can thus be positioned centrally above the stem at the level of the handlebars. This ensures that there is space and order on your handlebars and that you have a good overview of all values even if you're not riding a mountain bike. The Butler fits on handlebars of 31.8 and 35 mm diameters.

The Classic: The classical SIGMA GPS handlebar bracket can be fixed in place without tools in a few seconds with two cable ties. This gives you a choice between installation on your handlebars or on the stem and the device fits handlebars of all sizes.

Up Where The Air Is Clear: A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provide you with reliable information about altitude allowing a precise recording of your track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS or you can set altitude manually.

Pioneer: Connect your ROX 4.0 with your komoot app and leave your smart phone in your pocket. Receive turn-by-turn navigation from the komoot app on your ROX 4.0. It can be displayed either as an arrow on the display or inside the Red Circle. This circle on the display is highlighted in red and shows the distance to upcoming turn-offs as coloured bars that get shorter as the turn-offs get nearer. The number of metres to the next turn-off is also displayed next to the circle.

E-Bike-Ready: You ride an e-bike? No problem. The ROX 4.0 is e-bike-ready and can be easily connected to many e-bikes. Your GPS bike computer establishes a connection to the compatible e-bike system and shows you the current assist mode battery status and light and other data on the display. You can use this list to find out if your E-BIKE is compatible with the ROX 4.0.

Best Measurements: Do you need more data or even greater accuracy for your values? ANT+ and BLE enable you to connect external sensors such as speed heart rate and cadence sensors to your ROX 4.0. You can find accessories sets with various sensors for your ROX in our shop.

For Data Collectors: You can use the SIGMA RIDE app to collect your training data transfer them to your smart phone via BLE and quickly set your favourite display views on your smart phone. The most important data and statistics can be read from your smart phone in real time with the SIGMA RIDE app's LIVE function and assessed conveniently.

Be There Live: Record your data with your bike computer and analyse them right away with the SIGMA RIDE app's LIVE view. You can set your individual display views extremely easily while you're riding.

Stay Tuned: Smart notifications connect you to the outside world even when you're riding. Notifications of incoming calls and messages to your smart phone appear on your display.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it

Very fun interactive toy
Color: Brown/Wild Duck, Size: Medium
This toy is very versatile. There's no stuffing yet it's very soft so it can be used as a tug toy. It also makes for a fun fetch toy because it has a cavity to put a water bottle. It gives your dog something that crinkles and can be pierced when bitten and easily replaced with another empty bottle whenever necessary. That is what really makes this toy the standout of all the ones offered by Best Pet imo. I don't expect this to last forever but once my pup gets bigger we'll probably get the large size for her because there's not too many all in one fetch and tug toys at an affordable price.

Great Toy, but Big Dogs Destroy the Squeakers Fast
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Large
My big dogs had the squeaker torn out in no time, but my little dog absolutely loves this toy. It’s the perfect size for her, and she carries it everywhere. Durable enough for small pups, just not tough enough for heavy chewers. Still a fun toy overall!
