German bicycle manufacturer Serious, is well known for manufacturing several of the market’s most reliable models.

Seriously good bikes for all levels

The Bikester.co.uk website stocks a comprehensive range of Serious bikes that are ideal for experienced or novice cyclists. Some of its best-known models include:

  • Shoreline - for those who love to mountain bike, Serious offers the classic Shoreline MTB hardtail model, perfect for those who like to challenge themselves. With its lightweight frame and superb riding behaviour, you will always maintain good control over the bike – even when the surface is unstable and you are travelling at high speed. The wheels are robust and designed to withstand regular outings, and the components of the bike are of a very high quality.
  • Rockyville - looking for something more beginner level? Then the Rockyville MTB is an ideal choice and a great introduction to mountain biking. With its sporty, classic design and lightweight aluminium frame, the Rockyville is a leisure and multi-use bike that leaves its mark not just for its excellent price/performance ratio but also because of its reliability, durability and comfort.
  • Eight Ball - the Serious Eight Ball MTB is another popular model with beginner-level cyclists and mountain bikers in mind. It is as at home on rugged off-road terrain and countryside tracks as it is coasting along through the big city. The perfect bike for fun or nature!
  • Tenaya - Serious also produces a line of hybrid bikes that both maintain high performance and are affordable. The Tenaya model is built for all types of terrain, it has very stable and lightweight brake discs and good suspension, handling the pressure well on uneven and rugged terrains.
  • Athabasca - the Athabasca is a hybrid bike for commuting or having fun. Fitted with the Shimano Deore gear system, you have 30 speeds with which to tackle different gradients and with its superior braking power it gives you full control over your bike, no matter the conditions you are cycling in.
