The lockable bike bag
The name BikeBoot was derived from the British phrase for a storage area in the automobile the 'car boot'. However, in this case, it is for a bicycle.
The BikeBoot allows the cyclist to store items, while on the move or while the bike is left unattended, in a secure and lockable purpose-built bag which is fixed to the bicycle using the existing bottle holder bolts.
Using the standard bolts found on almost all bicycles the BikeBoot will allow you to hold not only a sports bottle while cycling but also other items such as bike cable lock, tools, or any number of soft belongings.
While that already makes it more versatile than a normal bottle holder it becomes even more useful when used as a lock box. You can use the BikeBoot to hold a range of items securely within the 0.5 litre compartment. You could store many items including lights, speedometer, tools or even your beloved bear.
A layer of durable, fire retardant (to BS5852) and waterproof fabric protects your items while also preventing the bolt heads from being accessed. A cut/slash resistant fabric (Cut-Tex Pro) inner lining and a steel reinforced seam protects your possessions from unwarranted attempts to access your locked bag.
A 50mm wide heavy duty recodable 5-digit combination padlock will be provided to prevent unauthorised access to the bag.Being recodable it allows you to input your personal number. No need for a key!
The bag is held upright using a poly-carbonate bottle holder whose flexibility allows for easy access into the bag.
All prototypes so far have been created with a basic slate grey colour scheme to prevent the product from being unduly targeted by would-be thieves.

Prototyping & Testing
Since the original conception of a lockable bike bag, there have been numerous prototypes and subsequent redesigns to get to the current streamlined product. This has always been envisaged as a bag that would be located on the bolts of the bottle holder. Several designs for the bag were considered before arriving at the present versatile shape.
As the bottle holder bolt is integral to the function of the BikeBoot
it is essential that this is tested to make sure it cannot be easily removed either by stealth or by brute force. The design utilises an inner lining that covers the bolt heads once installed, preventing them from being removed when the bag is locked. Destructive tests were carried out on scrapped frames, in order to ensure that the bolts/threads are strong enough to withstand a brute force attack. Both steel and aluminium frames were tested and as you can see from the GIF on the right, even the aluminium frames can withstand a great deal of pressure.
