Product Description


Typical High Street Price £269.99 


The IRONMAN Keauhou 24 is a sports hybrid bike with a strong lightweight alloy frame and performance component package.  

Designed to be "fit for purpose" with an alloy frame it benefits from a rigid light, but robust, chromoly front fork to help keep the steering agile and responsive. By keeping the overall weight of the bike down it is also not so tiring to pick up and handle.  

Fitted with Shimano 7 speed gears featuring Shimano Revoshift twist style shifter for easy shifting whilst pedalling and the transmission utilises a Shimano rear derailleur and Shimano 7 speed freewheel, so parts design by Shimano to work together. 

A 36 tooth chain ring with alloy 152mm crank and 14-28 tooth multiple Shimano freewheel offer a wide ratio of gears for all terrains and the transmission is enhance by the use of a cartridge bottom bracket for a smoother set up.

It's 24" lightweight double walled alloy rimmed wheels are fitted with 1.5" fast rolling tyres with a versatile "small block" tread.

Reach adjustable alloy brake levers with alloy V brakes deliver dependable stopping power.

The lightweight components include a 560mm alloy bar, alloy front loading ahead stem and alloy micro adjust seat post. 

The double chainset guards protect fingers and clothes but also helps stop the chain from jumping off the cogs.

Scaled to work for younger riders the IRONMAN Keauhou 24 features junior specific platform pedals, soft grips and a padded IRONMAN printed saddle.

Also benefits from under lacquered decals which means the stickers, frame and fork are sealed by an extra lacquer for added protection against the elements.

The IRONMAN Keauhou 24 aims to make cycling fun for children as they progress.

Suitable for inside leg measurements: 58cm to 71m (23” to 28”) 

Weight of complete bike is approximately 10.8 kgs
