Compares your speeds

Increase your speed on the way to work or school! A special feature of the R2 is its continuous comparison between your current and average speeds. The comparison is displayed with an arrow: If it is pointing up, you are faster than your average. If it is pointing down, you are slower.

data transfer

R2 wr

The speedometer’s direct cable connection with the transmitter ensures smooth speed measurement. The R2 WR needs no battery for wired transmission, and you can use your bike computer for years without changing its battery.

R2 wl

You prefer wireless? No problem: The wireless (WL) encoded transmission eliminates the need for cables. A wireless transmitter attached to the fork continuously sends bicycle speed data to the R2 WL’s receiver.

Compact, yet clear

With its simple, slim aesthetics, the R2 looks good on any bike. Its 31 x 39 mm display is just the right size to give you a perfect overview of your data. The bike computer is an eye-catcher on a road bike, city bike, or even a child’s bike.

Attachment with cable ties

r2 wr

You can mount the handlebar bracket and the speed transmitter to your bike with the cable ties (included). The bike computer receives all the data you need through the cable. The R2 WR can be removed and stowed conveniently at any time.

r2 wl

It could hardly be faster to mount: You can use the cable ties to secure the handlebar bracket for the R2 WL and the speed transmitter in no time. The bike computer can be removed and stowed conveniently at any time.

Easy to use

Setting up and using the R2 is very easy – and requires just one button. You can toggle through the functions easily, even while you’re riding. It is the perfect speedometer for children.

Speaks seven languages

The R2 is quite the linguist. Its full text display can be in English, German, French, Italian, Spanish, Dutch, or Polish – seven languages in all.

Long battery life

You do not have to worry about your R2’s battery life. A button battery (CR 2032) is enough to power your speedometer for a long time: The wireless bike computer can run on one of them for about two years.

Records multi-day tours

Do you like riding your bike on the weekend once in a while? Or are you a commuter and want to see your riding time and kilometres over several days? The R2 gives you all your data: it records total distance and ride time.

Usable in wind and weather

Showers on the way to work or school are no problem for the R2 – it is water-resistant and weatherproof.

Tyre sizes specified

You can conveniently select the pre-defined tyre sizes, ranging all the way from a small child’s bike to a 29″ bike, so setting the R2 is effortless. You can also enter the tyre circumference exactly to the millimetre.
