Free Items with this Bike! (Subject to stock availability)
As riders ourselves, we know exactly how to improve standard build bikes to ensure the best possible enjoyment for the rider. Instead of cutting prices, we spend extra time setting the bikes up to a high standard (which takes almost an hour per bike), and we also include the following items free of charge:
TartyBikes T-Shirt: We have Extra Small, Small, Medium, Large and Extra Large available (Men's sizes) in varying colours, click the link to see what we currently have available. Please ensure you specify which size T-Shirt you would like - it's unlikely our guess will be correct!
TartyBikes Chainstay Protector: Nifty little device to protect the paintwork on your frame when the chain slaps against it. One logo on each side... choose whichever you prefer!
TartyBikes MultiTool: What better to help tweak and set up your bike than a designed-for-purpose multitool?
You'll also receive some free TartyBikes stickers to use wherever you like!
Please ensure all the details on the warranty sheet supplied with the bike are adhered to. Certain circumstances (such as stripped threads or rounded crank arm tapers) only occur due to a lack of correct maintenance and all manufacturers are aware of these situations, so any claims due to incorrect maintenance procedures are much less likely to be successful.

Hi Deny - It's difficult to say for definite as it depends on how tall the child is, but between 5-10 years old seems to be right usually. Thanks, Mark
