flat and hill speeds.
That sounds great. Mine was 47.1 or .3 down some hill but I had to slow down due to cars getting in the way. Lolthis question crops up every now and again.
For me 49.6mph down Devils Dyke just outside of Brighton.
Could have gone faster but there was another cyclists in front of me and didn't want to move out of his slipstream
Funny lol next time, sit on the bike and let your friend drive lolMy Planet X did 70 once, but it was on the roof rack at the time.
