The TrekStor i.Beat road works as described and has both an excellent Fahhradhalterung: Among the features: => If the light function fine as a stand light on the bicycle or as additional light when driving lights not (being in the city, it is bright genung and the legal requirements are therefore met) => The charging process takes a little time but if you have a power charger cable with USB port has a problem or if you just sitting at the computer anyway => For battery life I can not say this is still untested, all recently is these depend on the volume and the brightness setting => The MP3 player provides a good functionality with decent sound (when the rubber cover over the terminals to be without this is not a sound body / volume available) Here I have to say that one would have been good but Shuffelfunktion not absolutely necessary. Otherwise still is an equalizer with sound presets available make the hearing itself. => The connections of the small "miracle" are quite good 2GB of internal memory can be expanded using a MicroSD to a total of 34GB. Also available an AUX port, and a mini USB. Port for charging but also for data transmission.
Thus a perfectly good product with a star deduction for the following reason: => In the manual is the device must be protected from moisture with no clear definition for the customer! As Bike gadget should least a splash protection exist, including but nothing is mentioned. Although I think that it should not be a problem (if the rubber cover located on the terminals) if slight drops hit the unit.
