28 INCH MEN'S TREKKING BIKE TR.2825 TREKKING BIKE SHIMANO ALIVIO RD-M3100 SGS.
Who said that a good bike has to be expensive? With the Airtracks TR.2825 you only get the bare essentials, no frills. As is usual for trekking bikes, it also has a derailleur, the 24-speed Shimano Alivio RD-M3100 SGS Shadow.
The side dynamo or the plug-in lights are replaced here with a complete lighting set from the brand Axa, powered by the Shimano Nexus hub dynamo. So you will not only be seen, but you will also be able to see yourself.
Ah yes, mud flaps from the company SKS you have it there too. Now your bike is ready to go in any weather.
The built-in V-brakes are not only in good condition, but also low-maintenance.
The simple gray design plays the role of theft protection in the metropolises.
With the pre-assembled luggage rack Racktime ECO 2.0 allows you to either attach side bags or mount or insert a bicycle basket.
It is not just cycling that makes you think green. This trekking bike has something else eco-friendly, namely the tires. swallow Road Cruiser's tread rubber is made with polymers exclusively from renewable and recycled raw materials.
Are you looking for something similar but in a women's version? No problem, we have exactly the right thing for you, take a look at the Airtracks TR.2825L trekking bike.
This bike is delivered 98% assembled. Only the handlebars and pedals need to be attached. The final assembly ready for use must be carried out by a qualified person.
