That's right Hamwich..there is a discreet box of tricks called a Speedbox that overrides the limiter on the electric motor.
Illegal in the Uk as 15.5 mph is the absolute max before it is classed as a moped and requires license,helmet,insurance etc.
I have tried a Bosch engine mountain bike with the Speedbox and achieved 37mph on the flat !!!
Remember you still have to pedal and max speed depends on gearing and your fitness..it will also drain the battery quicker.
