KELLYS Vanity 30 26" 24G dydis 13.5" (34,5cm) (balta/mėlyna)

The frame is made stronger than other types of bikes, and is designed for the best possible rideability. The geometry can be chosen to achieve optimum stability or manoeuvrability.

Material - aluminium, the most common. Lighter than steel and stronger than carbon fibre. Used in various types of bicycles. It has the best price-weight ratio.

Wheel sizes can be varied according to the purpose of the ride. 26" wheels are usually used for more challenging trail sections. These wheels are the strongest and most manoeuvrable, but have poorer rolling characteristics compared to larger wheels. The 27.5" size is ideal for maintaining the balance between manoeuvrability and stability. Many manufacturers use these wheels on low-frame bikes to maintain good rolling performance and a low centre of gravity. 29" wheels are used on most mountain bikes. They have good rolling characteristics and slightly improve shock absorption.

Front shock-absorbing fork - for comfort, better grip on different terrains, to avoid obstacles, and to descend downhill more safely.

Main tube is open for easier access for cleaning and replacement. This is important because the higher load of mud during uphill pedalling makes the chain of a mountain bike the quickest to wear out.

Rarely available with mudguards, but essential for clean clothing and comfortable riding in the worst weather conditions, and possibly available as an optional extra.

The saddle is narrow - for a firm and flexible enough seat for uphill pedalling.

Dynamos are rarely used to maintain a lightweight construction. Therefore, headlamps are chosen to be placed on the helmet to give greater visibility, especially on bends.
