just thought, if you dont have a speedometer on your bike, how do you know how fast your going, so how can you know your breaking the law, so how can they fine you. If your in a car you know its a 30mph zone and you can see your speedometer. If your on a bike, its different. I'm sure there is a loophole if you contest it
You cannot be charged for speeding on a pedal cycle, computer or not.
Any speed indicator on a 'road going' vehicle has to be approved by the VCA, Vehicle Certification Agency.
A bicycle does not have an Internal Combustion Engine ( wow, what a revelation ) so does not need VCA accriditation.
You will be told there is a speed limit in force and cautioned. A second caution will lead to 'Reckless cycling'.
There is a 10 mph limit in Mill Lane, Solihull ( approach to Mell Square ) and I have been 'finger wagged' by a copper there between Warwick Road and the bicycle parking metalwork outside Marks and Spencers.
Lode Lane, Solihull is a 30 mph limit, and I've been cautioned there.
