    Great topic title!

    I'm a guy, 70 kg (154 lb.), and to burn 500 calories in an hour of cycling, I need to be cycling at 25-30 km/h (16-18 mph) on flat ground, somewhat slower in hilly terrain. However, unless you're doing a lot of hills, or you're going slowly, weight is less important than speed for cycling; above about 20 km/h (12.5 mph), the majority of resistance comes from the wind, and wind resistance is proportional to your body's surface, not weight.

    You can use the calculator at http://www.bikecalculator.com to estimate your energy expenditure in cycling. It might be a little higher than the 400 in 90 minutes that Endomondo calculated. A lot depends on your speed. Plugging in your weight, assuming a 12 kg bicycle and a fairly upright riding position, that site calculates that you would burn 400 calories in 90 minutes on flat terrain at an average speed of 21.4 km/h (13.3 mph).

    Thanks you for the advice, I checked the link and ur right!

    Thank you everyone for your input on this thread, I was not expecting many answers...

    I have learned the following:

    1. Get over it, I am small so will not burn many calories, I might have an appetite of a 6ft7 bloke but need to eat and exercise for my size

    2. To be more efficient it is worth building some muscle, I will be renewing my gym membership tomorrow and have already asked a friend to show me how to lift

    I appreciate the time and advice you guys have given :flowerforyou:
