The Gilera Dna 50 is a great bike. Restricted it will do 28mph and 35mph downhill. Derestricted it will do 40 - 45mph and 52mph down hill. It is genrally good in the rain although too much will cut it out as I have experienced this. To fill the tank will cost aprox £7 and you shoulg get anything between 50 to 70 miles out of it. Going up hills restricted is slow approx 15mph. Derestricted you should get 30mph.depending on hill angle. I hope this has helped you! Ryan
