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.

Effective

This worked wonders on my car’s performance! After one use, the engine started idling much smoother and the throttle feels more responsive. A very high-quality German-made product.

Great for All Cars but Especially German Cars
Size: 300 Milliliter
I use this in our used VW we bought and it helps keep the carbon build up down with their direct injection feature. I pair it with their oil additive which helps lubricate the rings so they don't stick as much.

Significant Improvement in Performance with Liqui Moly Jectron
Size: 300 Milliliter
I've been using the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner in my vehicle, and I am thoroughly impressed with the results. The 300 ml bottle, though compact, has made a noticeable difference in the performance of my car. After adding the Jectron cleaner to my gasoline tank, I noticed an improvement in the engine's responsiveness and smoothness within just a few drives. The idling has become steadier, and the acceleration feels more robust and refined. It's as if my car has regained a level of vitality that I hadn't realized was missing. The cleaner is incredibly easy to use – simply pouring it into the fuel tank before filling up ensures it mixes well and distributes evenly throughout the fuel system. I appreciate that this product is designed to be compatible with all gasoline engines, making it a versatile choice for different types of vehicles. One of the most significant benefits I've observed is the reduction in start-up problems and engine hesitation. It's clear that the Jectron cleaner effectively cleans the fuel injectors, improving fuel atomization and combustion efficiency. This has not only enhanced the driving experience but also contributed to better fuel economy, which is a fantastic bonus given current fuel prices. The blue color of the liquid and the design of the bottle make it easy to identify and use, ensuring I don't mix it up with other products. Despite being a single 10.14 Fl Oz pack, this cleaner packs a punch, proving that a little goes a long way. In conclusion, the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner has exceeded my expectations. It has revitalized my car's engine, improved fuel efficiency, and provided a smoother, more enjoyable driving experience. I highly recommend this product to anyone looking to enhance their vehicle's performance and maintain the health of their fuel injection system.

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Size: 300 Milliliter, Size: 300 Milliliter
Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.
