Ooper you used a low resistance level and fooled the bike in thinking you went 33kph, your calories are low because you did not really go that fast if you would cycle real life, you would probably dont last 50 km. or if you did 100km you would need 5 hours or more.
i dont really care about cheaters online, but cheaters offline are the worst, they not only lying to themselfs but also to other people just to feel good about themselfs and their ego, just like my neighbour that tells everybody at work he really not eating much, but i see food deliveries atleast twice a week, he can admire his bike he lifts up the stairs everytime all he wants but he does not fool me, he will never loose weight.
but serious though, good that you have a bike, i admire people that want to make a change. i love exercise more then anything
