can any one give me advice about what speed I should expect from a AV76? I have one that I want to use one for bicycle pacing work, but I am uncertain as to wether it will be fast enough. I need it to be able to ride comfortably on a flat road at about 28-30 MPH, with a 13 stone rider (182 lbs). Is this going to be possible. It would help me to know before I strart work on the bike. Thanks.
