I am 65 years of age and beginning to worry about the routes we were taking when out cycling with my husband as my knees really didn't like some of the hills we were going up. Now with my own Liv Avail which I love, fitted with the C1 I have no fear where we go (I can get at least 35 sometimes even 40 miles depending how hilly the route is) and the enjoyment of cycling is very much back. The staff at Cytronex Winchester have been extremely friendly and helpful with any queries we have had and I am now looking to have a C1 fitted to a cross bike so I can join my husband on off road routes. 23.05.2018 I am still loving my bike and have done many miles. After encountering a problem I took it back to Cytronex in Winchester who very quickly found the fault and fixed it promptly. [seems it might have been something I was doing wrong) and, after fixing my back wheel, with some more instruction [so I did not repeat the fault ] sent me happily on my way. Thank you very much Mark and your friendly team.
