The "Bergamonster 20 purple" model from Bergamont, released in 2024, is a versatile children’s bike priced at 399 EUR. It features a robust frame made from lightweight AL-6061 tubing in a 20" size, resulting in a total weight of just 11 kg. The maximum load capacity is 65 kg, making it suitable for a wide range of young riders.
The bike is fitted with high-quality components that ensure a reliable and safe ride. The front and rear brakes are from Tektro and are V-brakes. The corresponding brake levers are also from Tektro; they are made of aluminium and offer an adjustable grip width to suit the child’s hand size.
The gear system on the Bergamonster 20 purple is controlled by the Shimano RD-TY300 rear derailleur and the Shimano SL-RS36 twist shifter, enabling easy operation and precise gear changes. The bike offers a total of 7 gears, supported by the Sunrace MF-M300 cassette (13–34t) and the KMC Z7 drivetrain. The Prowheel crankset has a length of 127 mm and a 36-tooth chainring.
The Suntour XCT JR fork, with 40 mm of travel and soft fork springs, provides additional comfort and control. The Marwi SP-700 pedals and the sealed cartridge bottom bracket contribute to the bike’s durability and ease of maintenance.
The BGM Comp Riser handlebars are 540 mm wide and fitted with BGM Kids grips to ensure a secure grip. The stem is also from BGM Comp and features a Syncros Stem Protector for added safety. The semi-integrated A-Headset headset (1 1/8") ensures stable steering.
The bike rides on Shining V-6NS rims and Kenda Booster tyres in size 20x2.20", fitted to both the front and rear. The hubs are also from BGM Comp and contribute to the bike’s overall stability. The Syncros Future Pro saddle and the BGM Comp seatpost provide comfort whilst riding. A practical aluminium kickstand from BGM rounds off the specification.
The bike’s packaging measures 21 mm in width, 64 mm in height and 110 mm in length, with a gross weight of 14,220 g. The Bergamonster 20 purple is available in a single ‘one size’ and is ideal for young riders looking for a reliable and well-equipped bike.
