We also developed a high quality real 20” mountain bike, ideal for smaller kids to practise a super fun ride and challenge themselves in any way. The geometry is also specific and delivers angles that will make the bike handle much better in curves and descents, providing the best sensations of a genuine mountain bike, where safety and fun complement each other.
Grom 20 was created for a modern and technological generation, which still enjoy the feeling of practicing sports activities in search of physical and emotional well-being, besides being able to expand their social relationships in environments closer to nature.
The Grom 20 comes equipped with Suntour suspension, disc brakes with proper safety protectors, 8 speed Shimano Altus gears, handmade aluminium frame, available in two colours. An ideal bike for girls and boys to start a complete lifestyle of fun on both wheels.
