BP6: ‘Softening’ the Highway Infrastructure
Reference: Title of Biker-Mate

Brief Biker-Mate is an energy absorbing
Description cushion which fits around sign posts
of Project: and other street-furniture to reduce
the energy transfer to a motorcyclist
striking the protected object.
The energy absorption is achieved
through a ‘honey-comb’ of material
which deforms during an impact.
The manufacturer makes the following claims:
• “Large radius impact face drastically reduces "piercing" effects which would be
seen upon impact with an unprotected structure/ post.
• Wrap around design shields the likely impact region of the post but does not
need to be installed around all sides, reducing the footprint and the cost.
• No sharp edges
• Resistant to vandalism (subjected to basic trials) – rigid, non brittle, slow melting
rate, secure connection etc…
• Easy fixing system, designed to fit Lattix & Round Posts
• Modular system is stackable enabling flexibility. Various heights can be achieved
o Height – 420mm nominal
o Depth –160mm nominal
o Low Mass/ Weight: only 2kg nominal
• Designed to enable easy access to lamppost electric panels.
• Thin gauge casing helps with load spreading, and interaction of absorption
The Biker-Mate system has been performance tested using Head Impact
Criteria and this appears to indicate a protection level greater than that
required by crash helmets approved to ECE 22.05.
Monitoring Performance testing by the manufacturer using static crush tests and
Data: dynamic impact tests appears to predict an absorbing capacity of around
6,000J, equivalent to 100% absorption for a 75kg rider travelling at over

not appear to be any results available based on casualty reduction.

reduced injury severity for PTW users striking the protected object.
Projects for Frangible Street Furniture (BP6 001).
Comparison: Motorcycle Friendly Crash Barrier (BP6 004).
Justification: In-depth studies do not appear to show that striking fixed roadside objects is
a major contributor to urban PTW injuries but for specific sites where the
casualty data indicates the existence of this problem the Biker-Mate could
be an effective counter-measure.
