In occasione dell’arrivo della stagione invernale, si ritorna a parlare di come sia salutare e conveniente muoversi in città in bicicletta, senza i venefici ingorghi del traffico. I vantaggi derivanti dall’uso quotidiano della bicicletta sono oramai noti a tutti, ma forse è bene ricordare, che il mezzo di trasporto più semplice e più economico che conosciamo non è un giocattolo: è a vehicle and is subject to the same rules as all other vehicles driven on the road, this must be conducted with caution. The bicycle, in fact, must have:
brakes (one for the front and one rear wheel)
the doorbell or a signaling device acusticau
a light yellow or white front
a red light back
a rear red reflector
four yellow reflectors on the pedals.
Since 2006 he has implemented a new European regulations for the safety of bicycles, on just four types of bikes: a boy, racing, city and trekking and mountain biking. In it you specify the requirements for their manufacture and define methods test to be applied to individual components in order to assess their strength. The rules also set some parameters for determining the structural integrity of the frames and forks and indicate the new braking performance. For example, a racing bike that travels at a speed of 25 km / h on a dry soil, it must have a stopping distance of up to 6 meters and at a speed of 16km / h on a wet ground, the braking distance will be up to 5 metri.Ovviamente devices mentioned must be certified and / or compliance.
